The question, “why is my Christmas cactus dropping buds,” is a common one here at Gardening Know How. Christmas cactus plants are succulents and hail from the tropical forests of Brazil. Most of these are sold straight from greenhouses where they have experienced strictly controlled lighting, moisture and temperature conditions. Just moving these lovely plants into your home can cause bud drop on Christmas cactus, but there may be other factors at work as well. Read on to prevent Christmas cactus buds falling off and preserve the incredible flower display. [图片]Why is My Christmas Cactus Dropping Flower Buds? Sometimes I feel like the world is conspiring against me and my plants. There are so many factors that can cause them to fall ill or fail to flower or produce fruit. In the case of Christmas cactus bud drop, the causes can range from cultural care, lighting, and even the fickleness of the plant to its situation. These plants need more water then true cactus and require a photoperiod of at least 14 hours of darkness to set buds. Other issues that may result in a Christmas cactus dropping flower buds are incorrect moisture, drafty conditions, hot or cold temperatures, and an excessive number of buds. [图片]Outside of root rot, bud drop on Christmas cactus is the most common problem. It is often caused by a change in environment, as these are sensitive plants brought up in carefully controlled environments. Simply moving your plant to a new location in the home can induce bud drop but new plants are in for a whole set of shocks that may contribute to falling buds. New temperatures, humidity levels, lighting, and care will confuse the plant and cause it to stop production on all those glorious flowers. Mimic the care from a greenhouse as closely as possible. Water evenly but do not allow soil to get soggy. Suspend fertilizing in late summer. Keep temperatures between 60 and 80 degrees F. (15-26 C.). Anything above 90 F. (32 C.) can result in Christmas cactus bud drop. Christmas cactus reside in the deeply vegetated tropical forests of Brazil. The dense tree canopy and other vegetation make a warm, shady womb in which these epiphytic plants develop. They require a period of time without much light to force bud formation. To ensure that there are no Christmas cactus buds falling off and production is dense, provide 14 hours of darkness in September until the end of November, but bright light the rest of the year. These forced “long nights” are naturally experienced by the plant in its native region. During the day, the plant should be placed in bright light for the remaining 10 hours but avoid scorching sun from southern windows. Once buds have set and begun to open, the false lighting regimen can end. [图片]Other Causes of Christmas Cactus Dropping Flower Buds If photo period and care are all correctly followed, there may be other problems with the plant. Incorrect fertilizer can cause the plant to push out so many blooms that it drops some off to make room for full development of the others. This abortive behavior is common in fruit plants, as well. Keep the cactus away from drafty doors and blowing heaters. These can dry the plant out and cause ambient temperatures surrounding the plant to fluctuate too drastically. The shock of such variant temperatures may cause bud drop. Indoor conditions in winter often reflect dry air, which is a condition Christmas cactus can’t tolerate. They are native to a region with rich, humid air and require some moisture in their atmosphere. This is easy to accomplish by placing a saucer filled with pebbles and water under the plant. Evaporation will moisten the air. Simple changes like these are often the answer to bud drop and can have you on your way to a fully blooming plant just in time for the holidays.

While the Christmas cactus may be known under various names (like Thanksgiving cactus or Easter cactus), the scientific name for Christmas cactus, Schlumbergera bridgessii, remains the same – while other plants may differ. This popular, winter-flowering houseplant makes a great addition to nearly any indoor setting. Christmas cactus is not only easy to care for but propagates easily too, making it an exceptional candidate for holiday gift giving. Let’s look at how to how to plant Christmas cactus and care for it. [图片]How to Plant Christmas Cactus The Christmas cactus is easily propagated by cutting a short Y-shaped segment from the stem tips. Make certain, however, that the cutting is taken from healthy plant foliage only. Plant the segment approximately a quarter of its length deep in slightly sandy soil. Moisten evenly and place the cutting in a well-lit area, staying away from any direct sunlight. To root cuttings for new plants, cut back shoots from the tips, cut at the second joint of each tip. The cutting should show signs of growth within a few weeks, at which time the plant can be transferred to another container, if desired, with a looser potting soil mix of compost, loam and sand. [图片]How to Care for Christmas Cactus Advice for Christmas cactus care tells us that it performs well under average home conditions with moderate care. The Christmas cactus will adapt to low light conditions, but the plant will produce blooms more readily if exposed to brighter light. That being said, too much direct sunlight can burn its leaves, so keep the Christmas cactus in an appropriate area to avoid this. Christmas cactus moisture is important as well. The plant requires frequent and thorough watering, during its active growth in spring and summer, keeping the soil slightly moist. Allow Christmas cactus moisture levels to drop and dry out some between watering intervals, but never completely, and never let the plant sit in water, as this will lead to root and stem rot. Applying a mild houseplant fertilizer solution every other week is also acceptable. [图片]When considering how to care for Christmas cactus, keep in mind it also prefers temperatures hovering between 60 and 70 degrees F. (15-21 C.) with average to high humidity levels. Placing a tray of pebbles filled with water beneath the Christmas cactus container is a good way to add more humidity to the home. Once the Christmas cactus has ceased all flowering (usually by fall), or about six to eight weeks before you want the plant to rebloom, you should allow the plant to begin its dormancy cycle by cutting back on Christmas cactus moisture and reducing both light and temperature. Simply cut back the watering and make sure the plant receives 12-14 hours of darkness and average temperatures around 50-55 F. (10-12 C.). Also, keep the Christmas cactus away from drafty areas. When you know how to care for Christmas cactus, this plant is not difficult to manage, and when given proper care and placed in a suitable location, the Christmas cactus may even surprise you with additional blooming cycles throughout the year.

Burro’s tail cactus (Sedum morganianum) is not technically a cactus but a succulent. Although all cacti are succulents, not all succulents are cactus. Both do have similar requirements such as gritty soil, good drainage, sunshine and protection from extreme cold temperatures. Growing burro’s tail provides fascinating texture as a graceful houseplant or lush green exterior plant in many landscape situations. [图片]Burro’s Tail Information Burro’s tail is a heat and drought tolerant plant well suited for warm to temperate regions. The thick stems appear woven or plaited with leaves. The succulent is green to gray green or even blue green and may have a slight chalky look. Try a burro’s tail houseplant or use it on the patio or full sun garden bed. [图片]Burro’s Tail Houseplant The misnamed burro’s tail cactus produces long, sweeping stems that are arrayed with thick, fleshy green leaves. The succulent thrives indoors in a well-drained container where bright sunlight bathes the plant. A burro’s tail houseplant will grow equally well in a mixed succulent container or as a hanging specimen. Slowly introduce the plant to full sun once purchased to allow it to acclimate first, as light conditions vary from nursery to nursery, etc. Provide even moisture and fertilize with cactus food during the growing season. Divide the plant when it gets too large for a container and transplant it every couple of years to provide it with fresh nutrient-rich soil. Burro’s tail care is easy and makes it an excellent plant for the novice gardener. [图片]Burro’s Tail Propagation Burro’s tail features long stems laden with small, rounded leaves. The leaves fall off at the slightest touch and will litter the ground after transplanting or repotting. Gather the leaves and insert them partway into a moist soilless medium. Burro’s tail plants can tolerate periods of drought, but the new potential plants need to be kept lightly moist until they root and establish. Propagating burro’s tail will ensure multiple enough of this versatile plant to play with and apply to many different indoor or outdoor landscaping situations. Propagating will also make numerous starts to share with friends and family or spread around the garden. Growing Burro’s Tail Outdoors One of the most fun plants around, this succulent is simple to grow. Outdoor plants may need winter protection with a light layer of mulch to protect them from cold. Plant the burro’s tail in full sun where there is shelter from drying and damaging winds. [图片]Growing Burro’s Tail Outdoors One of the most fun plants around, this succulent is simple to grow.

Cacti are the perfect plant for the novice gardener. They are also the perfect specimen for a neglectful gardener. Bunny ears cactus plant, also called angel’s wings, has ease of care combined with an original appearance. The thick pads of this plant are adorned with fuzzy glochids, or short bristles, that resemble the fur of rabbits and grow in earlike pairs. Even a beginner can learn how to grow bunny ears cactus and enjoy the soft appearance of the plant without a lot of typical houseplant fuss. [图片]Bunny Ears Cactus Information Bunny ears cactus (Opuntia microdasys) originated in Mexico and is a denizen of arid, desert-like areas. Growing bunny ears cactus is as simple as mimicking its native regional conditions. So if you have a dry, low humidity home and plenty of sunny exposure, bunny ears cactus plant might be the perfect plant for you. Bunny ears forms a 2- to 3-foot tall plant with a spread of 4 to 5 feet in its native habitat. In the home, it is a slow growing plant that will likely reach 2 feet in height and have about the same width. It makes an excellent container plant with its paired 3- to 6-inch long pads, which start out a rosy red and deepen to bright green. An interesting bit of bunny ears cactus information is that it does not develop spines. Instead, it grows glochids, which are short whitish brown prickles. These still have the ability to bite, so caution is urged when handling the cactus. If you are lucky, the plant may produce 2-inch wide creamy yellow flowers in summer, followed by globular purple fruits. [图片]How to Grow Bunny Ears Cactus As with most succulents, you can start new bunny ears plants with a pad taken from the cactus. Use extreme caution when removing a leaf because the glochids dislodge easily and are very difficult to remove from the skin. Use thick gloves or newspaper to pick up the pad. Allow the end to callus for a few days and then insert into cactus soil. Use a good cactus mix for growing bunny ears cactus, or make your own with 40 percent potting soil, 40 percent sand and 20 percent peat moss. The pad usually roots within a few weeks. Bunny ears cactus requires a well-drained container for indoor use. An unglazed clay pot allows for evaporation of excess moisture, which is a prime killer of these plants. They can also grow outdoors but are only hardy in United States Department of Agriculture zones 9 to 11. [图片]Bunny Ears Cactus Care These plants are a gardeners dream for their low maintenance and interesting appearance. Water can be the death of the plant but it does need consistent moisture during the growing season. Water the plant when the top one inch of soil is dry. Allow the water to drain out of the pot and remove any excess from the saucer. During fall and winter, water lightly only every 3 to 4 weeks. Fertilize the plant every other water period during spring and summer with a diluted houseplant food or cactus formula. Occasionally, the plant will be beleaguered by pests such as mealybugs and scale insects. Combat these with a cotton ball soaked in alcohol. Bunny ears cactus should be repotted every 1 to 2 years. Wait at least a week after repotting to water the plant. Other than these steps, bunny ears cactus care is limited and the plant should reward you with its abundant pads and interesting features for years.

Fans of Doctor Seuss illustrated books may find similarity of form in the bizarre boojum tree. The unique architectural shapes of these upright succulents, lend a surreal note to the arid landscape. Growing boojum trees requires bright light and warm temperatures. Among the many interesting boojum tree facts regards its shape. The Spanish name for the tree is Cirio, which means taper or candle. [图片]What is a Boojum Tree? Boojum trees (Fouquieria columnaris) are native to the Baja California peninsula and parts of the Sonoran desert. The plants are part of rocky hillsides and alluvial plains where water is rare and temperatures may be extreme. What is a boojum tree? The “tree” is actually a striking cacti with an upright form and imposing columnar height. Southern gardeners in arid regions can grow a boojum tree outdoors, while the rest of us will have to content ourselves with greenhouse and interior specimens that will not reach the heights those wild plants can achieve. Cultivated boojum trees may command a price tag of $1000.00 per foot (ouch!). The plants grow slowly, putting on less than a foot of dimension per year and wild harvest is prohibited due to the protected status of this cactus. Boojums in the wild have been found at 70 to 80 feet in height, but cultivated plants are significantly less at only 10 to 20 feet tall. The trees resemble taper candles with tiny bluish-green leaves that drop off when the plant reaches dormancy. These are cool season plants that do the majority of their growth from October to April and then go dormant in the hotter weather. The main stem is succulent and soft while smaller branches appear perpendicular to the trunk. Flowers are creamy white in clusters on the terminal ends of branches from February through March. [图片]Boojum Tree Facts Boojum trees are named after a mythical thing found in the work, The Hunting of the Snark, by Louis Caroll. Their fantastic form resembles an upside-down carrot and groups of them create quite an astounding display as the vertical trunks snake up from the earth. Boojum trees are quite rare due to seed disputes and their protected wild status. The drought tolerant cacti are perfect in the southwestern landscape and provide vertical appeal that is enhanced by thick-leaved succulents and other xeriscape plants. Gardeners who wish to try growing Boojum trees should have deep pockets, since purchasing even baby plants can be quite expensive. It is illegal to harvest wild plants. [图片]Boojum Tree Care If you are very lucky, you can try to grow a boojum tree from seed. Seed germination is sporadic and the seeds themselves can be difficult to find. Once seeds are sown, cultivation is similar to any other succulent. The plants need light shade when young but can tolerate full sun when mature. Sandy, well-drained soil is a must with superior drainage, as the worst evil to befall a boojum tree is root rot. Water potted plants once per week when they are actively growing. During dormancy the plant can do with half its normal water needs. Container boojum tree care requires addendum nutrients to supplement the potting mix. Feed the plant in February weekly with balanced fertilizer diluted to half. Growing boojum trees isn’t difficult provided you can find one and you don’t over water or feed the plant.

Barrel cactus are the classic desert denizens of lore. There are two genus types, the Echinocactus and the Ferrocactus. The Echinocactus has a fuzzy crown of fine spines, while the Ferrocactus are ferociously thorned. Each one can be grown as a houseplant or in less common situations the arid garden and are attractive additions to a succulent display. Growing barrel cactus requires a sunny location, well-drained potting soil and minimal watering. [图片]How to Grow Barrel Cactus Barrel cactus plants are characterized by their ribbed, cylindrical shape. The cacti come in many sizes and may be low and squat or as tall as 10 feet in height. The barrel cactus cares for lost travelers in the desert because it habitually grows tilted to the southwest. Caring for barrel cactus is quite easy and it makes a great plant for the beginning gardener. Site, water, soil and container are the key to how to grow barrel cactus. [图片]Potted cactus should be kept in the warmest room of the home in a bright sunny location. Direct southern sunlight may burn the plant in the height of the summer, so you should move them back from the window or turn the slats on your blinds to diffuse the light. Soil for barrel cactus is mostly sand with a little topsoil, perlite and compost. Prepared cactus mixes are suitable for growing barrel cactus. Unglazed pots are best for potted cactus because they allow the evaporation of excess water. Water is a very important component to caring for barrel cactus. The plants are native to arid desert regions and usually have only rainfall to supply their moisture needs. Water your barrel cactus once per week in summer. The barrel cactus doesn’t need much water in winter when it is dormant. Water once between December and February. Adequate water in spring may cause the plant to produce a large yellow flower. Rarely the plant will then grow an edible fruit. The cactus naturally grows in low fertility areas so their nutrient needs are low. Fertilize the barrel cactus once a year in spring when it leaves dormancy and begins growing again. A low nitrogen liquid fertilizer is a good formula for the barrel cactus. The amount of fertilizer will depend on the size of your container and plant. Consult the packaging for guidance on the exact amount. [图片]Growing Barrel Cactus from Seed Barrel cactus can be easily grown from seed. Fill a flat with commercial cactus mix and sow the seeds on the surface of the soil. Sprinkle a thin layer of sand on top of the seeds and then the soil needs to be evenly misted. Cover the flat with a lid or plastic wrap and keep it in a warm location. The seeds readily germinate and can be transplanted when they are big enough to a larger container. Always use gloves when handling barrel cactus, which also go by the name “fish hook cactus.”

One of the trickier diseases of cacti is pythium rot. It most commonly affects barrel cactus and can be difficult to detect before it is too late to save the cactus. Pythium rot symptoms start at the soil level and generally begin in roots. This makes it one of the hardest diseases of barrel cactus to diagnose, as most of the damage is under ground. To add insult to injury, the soil is the host of the pathogen. If soil is infected, the plant will certainly become ill. There are no effective methods of control of pythium rot but some prevention can be undertaken. [图片]What is Pythium Rot in Barrel Cactus? Pythium is an internal soft rot that affects cactus and many other types of plants. In barrel cactus, it occurs when conditions are moist, when the plant is too deep in soil and when the cactus sustains injury. For this reason, clean, sterile soil and proper planting methods must be observed to prevent the pathogen from invading your cactus. Once the plant has the disease, there is no effective pythium root rot treatment. The cactus is best removed and destroyed. There are, however, preventative treatments for susceptible species. The disease stems from a soil borne fungus-like organism. Once the roots are contaminated, the disease works its way up the cambium of the cactus and eventually will infect the entire plant. Once this happens, there is nothing to be done and the plant must be discarded. There are several common species of Pythium, each with favorite plant targets. While the disease is rarely found in commercial soil, it is easy to introduce through contaminated tools, old dirty pots and from animal activities. Even the use of dirty garden gloves can pass the pathogen into fresh, sterile soil. [图片]Pythium Rot Symptoms Pythium disease is almost impossible to detect until it is too late. This is because it starts in soil at the plant’s roots. If you were to remove the plant, you could see that roots are mushy, discolored and rotten. Pythium rot in barrel cactus will also produce brown lesions on the roots. Once this occurs, the plant cannot uptake adequate nutrition and the whole core begins to die. The disease progresses upward, developing soft spots and decay as the whole stem turns yellow. If you watch the base of the plant for yellowing at the soil line, you might still be able to save it. Once the stem becomes squishy, however, the cactus is a lost cause. Pythium rot in barrel cactus is usually fatal. [图片]Pythium Root Rot Treatment Of all the diseases of barrel cactus, this is a particularly insidious variety. Because there are no adequate methods of control of pythium rot, the best defense is prevention. Avoid burying the plant in soil to the fleshy part of the stem. If the plant gets wounded at the soil line, keep water off the area and let it callus over. Preventative treatments can be applied by professionals to valuable specimens. These include mefanoxam and phosphytl-Al. Such treatments can be costly and are spotty in their effectiveness. Plants in containers should have only sterile soil and all tools need to be cleaned before using them with the cactus. With a little care and some luck, you can prevent a barrel cactus from ever getting infected and possibly losing this beautiful plant.

Fenestraria baby toes really does look a bit like the tiny digits of an infant. The succulent plant is also known as living stones, with larger plants producing small rock-like protuberant leaves. In fact, it shares the same family as Lithops, which is also referred to as living stones. The plant is widely available at nurseries and a live object of artistic interest. Instructions on how to grow a baby toes plant are easy enough for children and young people, who adore the fascinating little plant. [图片]Baby Toes Succulent Description Baby toes plants (Fenestraria rhopalophylla) are native to subtropical desert zones. They require bright sun and moderate water in well-drained soil with plenty of gritty matter. Mother Nature engineered them to be very tolerant of low nutrient soils with extreme weather conditions. The perennial succulents form columns of leaves that are thick and rise up like small toes with flattened tops. The tops possess a translucent membrane over the top of the leaf. The vertical leaves may be mistaken for stems but are really modified foliage. Baby toes succulent may be mottled, grayish green to fully gray or even brown. [图片]Baby Toes Plant Propagation Like many succulents, Fenestraria baby toes produces offsets as the clusters of leaves mature and spread. These are easy to divide from the main clump and will readily produce another plant. Baby toes bloom in late summer to autumn with daisy-like flowers in a variety of hues. The seeds from the plant germinate sporadically and grow extremely slowly. Faster baby toes plants are achieved by dividing off the side growth. [图片]How to Grow a Baby Toes Starting baby toes from seed can be rewarding but you need a few key elements for a successful venture. First, the container should be shallow and well-draining. Make up a growing medium with equal parts coir, potting soil, sand, fine gravel and perlite. Moisten the mixture in the pot lightly and strew the seeds evenly on the surface of the soil. Sprinkle a light dusting of sand over the seeds. They will push the sand out of their way as the seedlings emerge. Cover the pot with clear plastic and place in a low light area until germination. Mist the plants after they emerge and remove the cover for half an hour daily to prevent fungal growth. [图片]Care of Baby Toes Move pots to a fully sunlit area where temperatures range at least 65 F. (19 C.). As with most succulent plants, the biggest problem is over or under watering. While Baby toes are tolerant of drought conditions, they need moisture to store in their leaves to sustain them during the growing season. Baby toes have few pest or disease problems, but do watch out for rot when plants are over watered or in pots that don’t drain well. Fertilize in early spring with a half dilution of cactus and succulent food. Suspend watering in the dormant season from November to February. Other than that, care of baby toes, is so easy the infant whose toes they resemble could almost grow these great little succulents.

Aeoniums are fleshy leaved succulents that grow in a pronounced rosette shape. Growing aeoniums is easy in areas with few freezes. They can also grow indoors, in a sunny window where temperatures are toasty warm. Learn how to grow an aeonium plant for unique texture and form in both indoor and outdoor garden displays. [图片]What Are Aeoniums? Succulent plants have a special adaptive survival strategy for hot, dry locations. They come in a wide range of colors, textures and sizes. What are aeoniums? These plants also have the fleshy leaved characteristic of succulents, where they store moisture. Unlike many other succulents, however, aeonium have shallow root systems and cannot be allowed to dry out completely. Only the top few inches of soil should be allowed to dry out when growing aeoniums. There are over 35 aeonium species, in a graduating range of sizes. [图片]Aeonium Uses Consider growing aeoniums as part of a cactus or succulent display. They do well in shallow pots with a mixture of cactus soil and peat. You can combine them with other plants such as aloe, agave or jade plants. Place a thin layer of inorganic mulch such as ornamental rock around the plants and place in a sunny warm location. For outdoor use, place them along sunny borders or in rockeries. In temperate or cooler zones, frost may kill the foliage and the rosette will fall off. If the plant is mulched it will grow anew in spring. [图片]How to Grow an Aeonium Plant Provide the plant with well-drained soil in a sunny location. They prefer temperatures between 40 and 100 F. (4-38 C.). These succulents are very easy to grow from cuttings. You really just have to cut off a rosette and let the cut end dry out for a couple of days. Then set it in lightly moist peat moss. The piece will root quickly and produce a new plant. [图片]Caring for Aeonium Plants Aeonium care is remarkably easy. Plants in containers require more frequent watering than those in ground. Fertilize aeonium in containers once annually in spring when new growth commences. In-ground plants rarely need fertilizer, but may benefit from a light coating of mulch just around the base of the plant. Be careful not to pile it up around the stem or rot might set in. The most common problems when caring for aeonium plants are root rot and insects. Root rot is prevented by using clay pots with good drainage or checking soil percolation prior to planting. Keep the roots moist but never soggy. Good aeonium care also requires you to watch for pests. Mites and scale may attach the succulents. Combat these with horticultural soaps or neem oil. Be careful when using soap spays, however. Spraying too frequently can cause discoloration and lesions on the skin of the plant.

Agave is a long-leaved succulent plant that naturally forms a rosette shape and produces a flower spire of attractive cup shaped blooms. The plant is drought tolerant and perennial, making it ideal for the mature arid garden. Many agave plants are native to North America and are adaptable to colder climates in the Pacific Northwest and even Canada. [图片]Types of Agave Almost every climate is capable of growing agave as some are hardy down to single digits for short periods of time and with shelter. Agave is in the Agavaceae family of succulents which include dracaena, yucca and ponytail palms. The century plant (Agave americana) is one of the most notorious landscape agaves. It produces a lovely inflorescence (flower) and then the main plant dies, leaving behind pups or offsets. The American agave or American aloe, as it is also called, has a white stripe running down the center of the leaves. It is a warm season agave only. There are many other types of agave, which makes it easy to find and garden with this stunning plant. Some of these include: Agave parryi Agave ocahui Agave macroacantha Agave gigantensis [图片]Planting Agave Agave have a large tap root and do not transplant well, so choose an appropriate site when planting agave. The majority of the roots are surface roots and do not require a deep hole if planted when young. Check your soil for drainage, or if planting in heavy clay soils amend the soil with sand or grit. Mix in enough sand to make the soil halfway comprised of grit. Water the plant diligently for the first week and then cut it to half the second week. Taper off even more until you are only watering once every week or two. [图片]How to Grow Agave Growing agave is easy if you plant the right variety in the right location. Agaves need full sun and gritty soil that percolates easily. They can even do quite well when potted but use an unglazed clay pot that will allow evaporation of excess moisture. Water needs are moderate to light depending upon the heat of the season but the plants should be allowed to dry out before irrigation. In spring they benefit from the application of a granulated time release fertilizer that will provide nutrient needs for the season. Many varieties of agave will die after blooming and then produce pups or offshoots from their base to replace themselves. On varieties where the parent plant doesn’t die after flowering, it is a good idea to get long handled pruners and remove the spent bloom. After establishment, neglect is actually how to grow agave and produce happy plants. [图片]Agave Plant Care in Pots Agave that are grown in pots require even more grit in the soil and can actually be planted in a cactus mix. The addition of small rocks or pebbles to the soil increases the drainage capabilities of the container. Agave plants in containers will require more water than those in the ground and will need to be re-potted every year or so to replenish soil and root prune the plant. Agave plant care for container grown plants is otherwise the same and it affords you the ability to bring sensitive forms indoors when temperatures plummet.
