Peace lilies are so enchanting; it may come as a surprise that they are rugged plants that tolerate a variety of light conditions, including semi-darkness. Peace lilies can even survive a certain amount of neglect at the hands of busy or forgetful indoor gardeners. Do peace lilies need fertilizer? Believe it or not, many folks prefer to skip the fertilizer and their peace lily plants do just fine without it. However, fertilizing a peace lily now and then is important if you hope to encourage blooming. Read on to learn more about fertilizer for peace lilies.[图片]When to Feed Peace Lily Plants Peace lilies aren’t fussy and they really don’t need much fertilizer. The best time to apply peace lily fertilizer is when the plant is activity growing or producing blooms. As a general rule, two or three feedings throughout the growing season is plenty. If you choose to feed your plant more often, use a very diluted fertilizer. Avoid overfeeding, as too much fertilizer may create brown spots on the leaves. If the flowers are a little green around the gills instead of creamy white, you are probably overdoing the fertilizer. Either cut back or dilute the concentration.[图片]What is the Best Peace Lily Fertilizer? When it comes to fertilizing a peace lily, any good quality, water-soluble houseplant fertilizer is fine. Look for a product with a balanced ratio, such as 20-20-20, diluted to one-half or one-quarter strength. Be sure to water after feeding your peace lily to distribute the fertilizer evenly around the roots. Never apply fertilizer to dry soil, which may scorch the roots.[图片]

Peace lily, or Spathiphyllum, is a common and easy-to-grow houseplant. They are not true lilies but in the Arum family and native to tropical Central and South America. In the wild, peace lilies are understory plants that grow in moisture rich humus and in partially shaded light. Heat, water levels, lighting and disease are potential causes for drooping peace lily plants. Once you discover the cause, it is generally easy to revive a wilting peace lily. But first you need to put your Sherlock Holmes hat on and investigate the reason a peace lily keeps wilting.[图片]My Peace Lily Keeps Wilting Peace lily is an attractive foliage plant that produces a flower-like spathe, which is a modified leaf that encloses the real flower, a spadix. While these plants are known for their ease of care, occasional issues may arise. One of the most common is droopy leaves on peace lily. Wilting peace lilies can occur due to several conditions. It is important to look for pest and disease issues, but the problem could also be cultural.[图片]Watering issues Spathiphyllum are Aroids, which means they are known for their glossy foliage and characteristic spathe. Peace lilies grow naturally in tropical rainforests. These plants need water but once per week is usually enough. Water until the moisture comes out the drainage holes in the plant’s container. This will ensure that the root ball is getting moisture. When you repot the plant, separate the roots of the ball out into the new soil so they can gather moisture. One common mistake is to water into a saucer and let the moisture percolate up into the roots. This is time consuming for the plant and it may not be getting adequate moisture. Additionally, the standing water in the saucer may induce root rot and attract insect pests. Good watering practices can quickly revive a wilting peace lily. Lighting, temperature and soil Correct cultural care needs to be given to peace lily plants. Consistently wilting peace lilies are often the result of simple cultural issues that are easily corrected. Place plants in indirect but bright sunlight. Keep them in a container that is twice as large as the root ball. Wild peace lilies live in warm, tropical regions and require temperatures of 65 to 75 degrees Fahrenheit (18-23 C.) during the day and about 10 degrees cooler at night. Most thrive in average indoor temperatures but exposure to extreme heat or cold can cause drooping peace lily plants. Move any plants that are near the furnace or a drafty window or door. Good, well-draining soil is essential. Soil with a high amount of clay can create unfavorably boggy conditions and those with too much grit or sand will simply drain away the moisture added before the plant can uptake it. The best potting soil for a peace lily is a fine, porous mixture containing peat moss, fine bark, or perlite.[图片]Pests and disease When water levels and other cultural issues have been adequately addressed and the plant is still stressed, look for signs of pests or disease. Mealybugs are the most common pest problem. They can be seen as cottony bits of fluff adhering to the plant or in the soil. Their feeding behavior on plant sap reduces plant vigor and disrupts the flow of nutrients and moisture to foliage, causing discoloration and wilting. Sharp sprays of water to rinse off the insects or the application of alcohol directly to the pests can correct an infestation. Cylindrocladium root rot is the most prevalent disease of Spathiphyllum. It occurs in the warm summer months and causes chlorotic areas and wilted leaves. Remove the plant from soil and treat the roots with fungicide. Then repot in a sterile pot with clean soil. Several other pathogens may be harbored in contaminated potting soil. These are generally fungal and may be addressed in a similar manner as Cylindrocladium.

Peace lilies (Spathiphyllum spp.), with their smooth, white blossoms, exude serenity and calm. Although they are not actually lilies, these plants are among the most common tropical plants grown as houseplants in this country. Peace lilies are tough and resilient, but they are susceptible to a few pests and diseases. Read on more information about peace lily plant problems, including common diseases in Spathiphyllum plants.[图片]Peace Lily Plant Problems Peace lilies may be tropical plants but they do not require kid-glove care. On the other hand, the better your cultural care matches the plant’s needs, the less peace lily plant problems you are likely to encounter. Peace lilies need indirect light, never direct light. If you position your plant a couple of feet from a window, it should be fine. Another alternative is to put it near fluorescent lights. Sufficient light is essential to preventing diseases in Spathiphyllum. These lovely plants prefer a humid location. They thrive in warm, moist conditions. You can satisfy your peace lily and avoid peace lily plant problems by keeping the temperature between 65 and 80 degrees Fahrenheit (18-26 C.). Increase the humidity for your peace lily by setting the plant on a tray filled with pebbles and water. Watering too often can bring on diseases of peace lily plants. Wait until you see the plant wilting before adding more water.[图片]Pests and Diseases of Peace Lily Plants Taking good care of your peace lily will mean it’s less likely to suffer from pests and diseases. Remove all dead leaves from the plant and the pot. Wipe down green leaves with a damp cloth occasionally to remove dust. Check the plant’s leaves for pests like spider mites, mealybugsand scale. These might have come into your home on other plants and can cause peace lily plant problems if not removed or treated. When it comes to diseases of peace lily plants, the two most common diseases in Spathiphyllum are Cylindrocladium spathiphylli and Phytophthora parasitica, both causing root rot diseases. The former type of root rot is transferred among plants by infected water, the second by infected soil.[图片]If your plant has root rot, you’ll need to think about treating peace lily diseases. First, try to figure out what your plant has. You’ll recognize root rot disease in Spathiphyllum if you notice that a peace lily has yellowing leaves and a wilting appearance. If its roots are also rotting, it likely has root rot. Oftentimes, cleaning off the roots and repotting the plant in fresh, healthy soil will help.

Peace lilies (Spathiphyllum), also known as closet plants, are a popular choice for offices and homes. When it comes to indoor plants, peace lily plants are some of the easiest to care for. But, while peace lily plant care is easy, proper growing conditions are still important. Let’s take a look at the care of peace lilies.[图片]Growing Peace Lily As Houseplants Peace lilies make excellent houseplants for the home or office. These lovely plants not only brighten up a living space, but are also excellent at cleaning the air of the room they are in. Most commonly, these plants have dark green leaves and white “flowers.” But what most people think of as the flower is actually a specialized leaf bract that grows hooded over the flowers. Like many popular indoor plants, peace lilies enjoy medium to low light. Which kind of light you need to provide will depend more on what you want your peace lily plant to look like. Peace lilies that are placed in more light tend to produce the lovely white spathes and flowers more, while peace lilies in low light will bloom less and will look more like a traditional foliage plant.[图片]Peace Lily Plant Care One of the most common mistakes in the care of peace lilies is overwatering. Peace lilies are far more tolerant of underwatering than overwatering, which is one of the most common reasons for a peace lily to die. Because of this, you should never water peace lily plants on a schedule. Rather, you should check them once a week to see if they need to be watered. Simply touch the top of the soil to see if it is dry. If it is, water your peace lily. If the soil is still damp, the plant does not need to be watered. Some people will go so far as to wait until their peace lily is starting to droop before watering their plant. As these plants are very drought tolerant, this method does not harm the plant and will prevent overwatering. Peace lilies do not need frequent fertilizing. Fertilizing with a balanced fertilizer one to two times per year will be enough to keep the plant happy.[图片]Peace lilies also benefit from repotting or dividing when they outgrow their containers. Signs that a peace lily plant has outgrown its container include drooping less than a week after being watered and crowded, deformed leaf growth. If you are repotting, move the plant into a pot that is at least 2 inches larger than its current pot. If you are dividing, use a sharp knife to cut through the center of the rootball and replant each half in its on container. Since the wide leaves on peace lilies tend to be a dust magnet, you should either wash or wipe down the leaves at least once a year. This will help it process sunlight better. Washing the plant can be done by either setting it in the bath and giving it a short shower or by placing it in a sink and letting the tap run over the leaves. Alternatively, the leaves of your peace lily plant can also be wiped down with a damp cloth. Avoid using commercial leaf shine products, however, as these can clog the pores of the plant.

Oxalis palmifrons is a fascinating and very attractive blooming perennial. Oxalis is the genus name of a plant from southern Africa that is made up of over 200 species. Oxalis palmifrons is one such species that gets its name from its leaves – tiny, symmetrical fronds radiating from the top of each stem, making it look for all the world like a tiny cluster of miniature palm trees. It also sometimes goes by the name palm leaf false shamrock plant, or simply false shamrock. But how do you go about growing Oxalis palmifrons? Keep reading to learn more about how to grow a palm leaf oxalis and palm leaf oxalis care.[图片]Palm Leaf Oxalis Plants Palm leaf oxalis plants are native to the Western Karoo region of South Africa, and they need similarly warm weather to survive. They can be grown outside in USDA zones 7b through 11. In cooler climates they work well as container plants on a bright windowsill. They grow very low to the ground, never getting more than a few inches tall. They also spread extremely slowly, reaching a width of two feet in about ten years. This compact size makes them ideal for container growing.[图片]How to Grow a Palm Leaf Oxalis Palm leaf oxalis plants are winter growers, meaning they go dormant during the summer. In late autumn, the leaves will emerge as bright green tiny palm trees. The flowers bloom light pink to white on stalks that reach just above the foliage. The leaves remain green through the winter, before the plant goes dormant again. Palm leaf oxalis care is relatively easy – water regularly but not too much, and give it full to partial sun. Bring it inside if your winters get chilly, and don’t give up on it when it fades with the summer. It will come back![图片]

Pachira aquatica is a commonly found houseplant called a money tree. The plant is also known as Malabar chestnut or Saba nut. Money tree plants often have their slender trunks braided together and are a low maintenance option for artificially lit areas. Money tree plant care is easy and based upon just a few specific conditions. Let’s learn more about how to care for money tree houseplants.[图片]Pachira Money Tree Money tree plants are native from Mexico to northern South America. The trees can get up to 60 feet in their native habitats but are more commonly small, potted ornamental specimens. The plant has slim green stems topped with palmate leaves. In its native region, money tree plants produce fruits that are oval green pods divided into five chambers inside. The seeds within the fruit swell until the pod bursts. Roasted nuts taste a bit like chestnuts and can be used ground into flour. The plants get their name because the Feng Shui practice believes it will bring luck to the owner of this fun little plant.[图片]Growing a Money Tree Houseplant USDA zones 10 and 11 are suitable for growing a money tree houseplant. In colder regions, you should only grow this plant indoors, as it is not considered cold hardy. The Pachira money tree is a perfect addition to the interior landscape and lends a tropical feel. If you want to have some fun, try starting your own Pachira money tree from seed or from cuttings. These plants do best when they are in full sun to partial shade. The best temperatures are 60 to 65 F. (16-18 C.). Plant the tree in peat moss with some gritty sand.[图片]How to Care for Money Tree These plants like a moderately humid room and deep but infrequent watering. Water the plants until the water runs from the drainage holes and then let them dry out between watering. If your home is on the dry side, you can increase the humidity by placing the pot on a saucer filled with pebbles. Keep the saucer filled with water and the evaporation will enhance the humidity of the area. Remember to fertilize every two weeks as part of good money tree plant care. Use a liquid plant food diluted by half. Suspend fertilizing in winter. The Pachira plant rarely needs to be pruned but as part of your annual money tree plant care, take off any damaged or dead plant material. The plant should be repotted every two years in a clean peat mixture. Try not to move the plant around a lot. Money tree plants dislike being moved and respond by dropping their leaves. Also keep them away from drafty areas. Move your Pachira money tree outside in summer to an area with dappled light, but don’t forget to move it back in before fall.

For unique interest in the home, look for the Fittonia nerve plant. When purchasing these plants, be aware it may also be called the mosaic plant or painted net leaf. Growing nerve plants is easy and so is nerve plant care.[图片]Fittonia Nerve Houseplants The nerve plant, or Fittonia argyroneura, from the Acanthaceae (Acanthus) family, is a tropically found plant with striking leaves of pink and green, white and green, or green and red. Foliage is primarily olive green with veining taking on the alternate hue. For specific color characteristics, look for other Fittonia nerve houseplant, such as F. argyroneura with silver white veins or F. pearcei, the carmine pink-veined beauty. Named for its 19th century discoverers, the botanists Elizabeth and Sarah May Fitton, the Fittonia nerve plant does indeed flower. The blooms are insignificant reddish to white spikes and tend to blend in with the remainder of the foliage. The blooms of the nerve plant are rarely seen when it is grown indoors as a houseplant. Hailing from Peru and other areas of the South American rain forest, this colorful houseplant craves high humidity but not too much irrigation. This little beauty does well in terrariums, hanging baskets, dish gardens or even as a ground cover in the right climate. The foliage is low growing and trailing with oval-shaped leaves on rooting mat forming stems. To propagate the plant, these rooted stem pieces may be divided or tip cuttings may be taken to create new Fittonia nerve houseplants.[图片]Nerve Plant Care As the nerve plant originates in a tropical setting, it flourishes within a high humidity environment. Misting may be required to maintain humid-like conditions. Fittonia nerve plant likes well drained moist soil, but not too wet. Water moderately and let growing nerve plants dry out between waterings. Use room temperature water on the plant to avoid shock. Growing about 3 to 6 inches by 12 to 18 inches or longer, the Fittonia nerve plant tolerates bright light to shade conditions but will truly flourish with bright, indirect light. Low light exposure will cause these plants to revert to green, losing the veins vibrant splashes of color. Growing nerve plants should be placed in a warm area, avoiding drafts which will shock the plant just as water that is too cold or hot. Think rain forest conditions and treat your Fittonia nerve houseplants accordingly. Feed as recommended for tropical houseplants per the instructions of your fertilizer brand. The trailing nature of the plant can lead to a straggly appearance. Prune the tips of the nerve plant to create a bushier plant.[图片]Nerve Plant Problems Nerve plant problems are few; however, as mentioned above, avoid overwatering as this can lead to root rot. Xanthomonas leaf spot, which causes necropsy of the veins, and mosaic virus may also afflict the plant. Pests may include aphids, mealybugs and thrips.

It’s not only attractive and easy to grow, but the miracle plant produces a very interesting berry that upon eating makes things taste sweeter. Learning more about growing miracle berries can make it easier for you to experience this unusual phenomenon for yourself. Keep reading to learn about caring for a miracle fruit plant.[图片]Miracle Plant Info: What Is a Miracle Berry? Miracle berry (Synsepalum dulcificum) is an evergreen shrub that is native to tropical West Africa. Outside of the tropics, it is a houseplant that is also known as sweet berry and miracle fruit. This interesting plant bears attractive and edible red fruit that are ¾ to 1 inch long with a seed surrounded by fleshy pulp. The miracle that this fruit performs is to make everything taste sweet. When you eat the fruit and allow the pulp to coat the inside of your mouth, it masks the real taste of bitter foods for a few minutes to several hours, depending on how much fruit you eat. This includes foods that are normally very sour, such as vinegar or lemons. Scientists are still unsure of how the fruit alters a food’s taste, but they think that it may have something to do with a protein with sugar molecules attached. The receptors on the taste buds seem to be temporarily altered when the fruit is eaten as a result of these molecules.[图片]Miracle Berry Growing In its native environment, the plant will reach up to 20 feet in height at maturity but only 5 feet when grown indoors, so make sure to locate it in a suitable area to accommodate this fairly large size. Growing miracle berries indoors requires a room with very bright light. However, it can be placed outside in a shady location when the weather is warm. This humidity-loving plant thrives when placed in a room with a humidifier or with a clear plastic bag wrapped around it to conserve moisture. Misting daily with water or setting the plant on a water-filled pebble tray can also help with raising humidity. Use only well drained, slightly acidic soil whenever you are growing miracle berries.[图片]Caring for a Miracle Fruit Plant Caring for a miracle fruit plant is not difficult as long as you keep the soil acidity constant. This can be done by using peat and perlite planting mediums and providing a fertilizer for acid-loving plants. Water the plant regularly but do not let the plant sit in water or it may become waterlogged and may develop root rot. Always feel the soil before watering. Now that you the answer to, “What is miracle berry?” you can begin your own miracle berry growing and explore the wonder of this interesting fruit.

Sometimes called Rose Grape, Philipinne Orchid, Pink Lantern plant or Chandelier tree, Medinilla magnifica is small evergreen shrub native to the Philippines where it is usually found growing on trees in tropical forests. However, Medinilla has been grown for hundreds of years as an exotic houseplant, once prized in Belgium by the wealthy and noble. Learn how you, too, can grow this exotic species.[图片]Medinilla Information Medinilla is a tropical shrub that can grow up to 4 ft. tall. It grows like epiphytic orchids, in holes and crotches of trees. Unlike orchids, though, Medinilla does not absorb atmospheric moisture and nutrients via velamen (corky epidermis of aerial roots). Instead, the plant has large succulent green leaves, which hold onto or store moisture similar to other succulent plants. In late spring to early summer, the plant is covered by drooping clusters of delicate pink flowers that look somewhat like grapes or wisteria flowers. These flowers are what gives the plant all its folk names.[图片]How to Grow Medinilla Plants Medinilla needs a warm and humid environment to survive. It cannot tolerate temperatures below 50 degrees F. (10 C.). In fact, 63-77 degrees F. (17-25 C.) is ideal for proper Medinilla plant care. It prefers warm days in high but filtered light, and cooler nights in the 60s. Cooler nights help the plant to send out more flowers. Before purchasing Medinilla, be sure you can give it the warm, humid conditions it needs year round. As a succulent, Medinilla does not need to be watered often, usually just thoroughly once a week. It does enjoy being misted by water often, especially in the dry winter months. If you have Medinilla as a houseplant, you may need to run a humidifier in the home during winter. Also, be sure to keep Medinilla plants away from air ducts and drafty windows.[图片]Medinilla Plant Care Instructions Caring for Medinilla plants isn’t difficult once you know what it needs. Grow the plant in filtered shade to full sun, though it prefers to avoid direct afternoon sun. During the flowering period, deadhead spent blooms to promote new flowers and keep the plant healthy looking. After the flowering period, give Medinilla regular houseplant or orchid fertilizer. At this point, your Medinilla can be cut back to keep under control and create bushier new growth. Be sure to leave at least one leaf set on each stalk you cut, or that stalk will die back completely. If you need to repot your Medinilla, do it after the flowering season. Repotting is an excellent time for Medinilla plant propagation, as the easiest way to create new Medinilla plants is by dividing an existing plant. When the time comes that your Medinilla has out grown its pot, just divide the plant in to several new pots.
