[图片]一、浇水与花盆大小的关系 浇水是个细致的工作，就连花盆的不同也会影响浇水的质量。有些#金桔 的苗很大，但是花盆较小，这种情况下浇水的量要多一点，反之，苗很小但是盆很大的情况则要少交一些。 [图片]二、浇水与生长时期的关系 若是金桔正值上涨的黄金时期，生长旺盛期多浇些水，休眠时期尽量不浇水。 三、浇水与天气的关系 这点就很容易理解啦，天气热的话，水分蒸发速度自然快，所以浇水量也要提高，反之天亮或者阴天的时候，可以少浇一点。 [图片]四、浇水与季节的关系 上文也有提到，春天刚刚到来之时，正是它生长的黄金时间。这时候，气温越来越高，所浇的水量要增大一点。早春时节，给金桔浇水一定要保证在中午前完成。夏天比较热，金桔的成长环境也是不错的，但是蒸腾作较大，浇水要多一些。 夏天大家都知道，正午时间是不能浇水的，所以浇水的时间应该是在清晨或者傍晚。 初秋时候，气温渐渐降下来，金桔的花开的相对慢一点，所以要少浇水。 冬季气温低，进入休眠期的金桔尽量不浇水。 [图片]

[图片]一、#盆栽竹子 的施肥技巧 1、刚刚栽种竹子时应该使用酸性或中性土壤，土壤里最好含有一些砂质，农田土也可。刚种植入盆时就可以适当的放入点有机肥了。 1、盆栽竹子是喜欢水的，但是大家往往没注意到。为什么呢？竹子生命力很旺盛，所以施肥浇水的时候都可以量稍微大一点，这样它们才能更好的生长。 2、盆栽竹子的施肥时间可以定为一个月一次，这个速度相对来说是对竹子最好的。 二、盆栽竹子施什么肥 1、盆栽竹子尽量使用有机肥，此种肥料中有大量的钾钙元素，竹子生长全靠它。除了对竹子本身比较好以外，还能减少污染，何乐而不为。 2、生长过程中缺肥或施肥过量都会引起疾病，所以要注意施基础肥料。因为盆栽的营养有限，春夏时节肥要薄，次数可以稍勤一点，不断补充盆土养分。 3、盆栽竹子一定要用有机肥。 [图片]温馨提示 给盆栽竹子施肥的问题解决了总会问到浇水怎么办。竹子是非常喜欢水的植物，所以盆土要处于水润状态，不能缺水。环境如果干燥，可以选择稍微多浇水，还有，在生长黄金时期应该多浇水。 [图片]

[图片]褐斑病 #褐斑病 对叶片能够产生较大的危害，通常叶片上会产生一种圆形的褐色斑点，这种病菌能够通过雨水传播，残留的病菌附着到叶片引起病发。 预防这种病的产生可以将植株扩大间隔，良好的通风能够有效的预防这种病的发生，发病期间，要少浇水少施肥，适当的喷洒一定的药物进行防治。 [图片]灰霉病 灰霉病一般会发生在生长中期阶段，会对植株的茎和叶造成伤害。土壤中会留存这种饼的病菌，每年春季来临的时候，随着空气在空中落到植株上进行侵害。遭遇这种病时，可以通过多施肥，勤浇水的方法来医治，这样能够提高植株的抗病能力。配合一定量的药剂，不长时间就能减缓疾病的带来的伤害。 [图片]苗腐病 它能够使植物的幼苗根茎产生病变。开始时呈现出不同形状的病斑，然后病斑会变成黑色，产生腐烂，植株就会死亡。植株生病的部位会产生白色丝状物，甚至可能穿透叶片。 这种病通过水分传播，在农田的低洼处，病菌的生存率较高，是导致植株染病的重要问题所在。通常可以将病株铲除，适当的进行浇水，避免水分的堆积。同时配合药物进行喷洒，能够有效的治理这种病。 [图片]

Succulents don’t always fare well when exposed to the hot sun day in and day out. In nature, succulents often grow under or near a shrub or tree where they receive bright light but not constant direct sunlight. Don’t automatically plant your succulent smack-dab in the middle of the garden, where it receives endless hours of direct sunlight, especially during the summer. Instead, carefully select its growing location where your succulent will receive enough sunlight, but not too much. [图片]1. Determine how much direct sunlight your succulent should receive each day. Consider whether your succulent plant requires only 4 hours of direct sunlight a day, which is the case with most succulents. Plan to provide succulents with afternoon shade in areas that are scorched by hot summer sun. 2. Plant your succulent on the east side of a building, tree or another structure that is exposed to morning sun if your plant should be protected from the afternoon sun. Plant it under a tree, if desired, that receives filtered sunlight throughout the day during the summer, which also protects it from the afternoon sun. Alternatively, plant your succulent in a sunnier location, such as on the west or south side of your home, if your climate is mild during the summer and is not afflicted with hot, scorching summer days. [图片]3. Examine your succulent 2 to 4 weeks after planting and several times during the summer. Notice whether it is indented, or has a tan, yellow or red color on the side that faces the most sun, both of which indicate that your plant is receiving too much direct sunlight. Determine whether your succulent is not growing well, which could mean that it needs more sunlight, especially if you are providing it with proper water and fertilizer. 4. Transplant your succulent to a sunnier spot, or prune nearby trees and shrubs to increase sunlight exposure, if necessary. Alternatively, transplant your succulent to a shadier site, or plant a shrub or other plants near it to provide more shade if your plant is getting too much sunlight. [图片]Tip Keep your succulent in a container for the first growing season so you can easily move it around until you find the best location. Slowly acclimate your succulent to its new growing location before planting it, especially if it was previously an indoor plant. Place it in the sun for 2 hours a day for 1 or 2 days. Increase the amount of time it spends in direct sunlight by one-half hour every day until it is exposed to the same amount of sunlight as it will get in its new location. Sketch your landscape and mark possible planting locations. Take a day to examine and record the amount of sunlight each area gets and what time of day.

Astroloba is a genus of flowering plants in the family Asphodelaceae, native to the Cape Province of South Africa. The name of the genus is derived from the Greek words “astros” (star), and “lobos” (lobe), and refers to the starlike shape of the petals, which appear at the end of the tube-like flowers. They are very closely related to the Haworthia genus, but are distinguished by their flowers being regular and not double-tipped. The flowers are small and white, and appear clustered on slender racemes. Astrolobas bear very regular, sharp, triangular, succulent leaves along their symmetrical columnar stems. They are slow growing, multi-stemmed, and their longer stems tend to sprawl in their rocky natural habitat. [图片]Growing Conditions and General Care Astroloba plants are increasingly popular as succulent ornamental, due to the extraordinary beauty of their leaf structure. Some have intricate patterns of lines, margins, spots and raised tubercles on their leaves. Nearly all of them display a crystal-like regularity in their leaf arrangement. This is not always apparent in wild plants, which are usually disfigured by their harsh habitat. In cultivation, Astrolobas are at their best when provided with some protection from full sun. In a semi-shade environment, with extremely well-drained soil and gentle conditions, Astrolobas can become remarkably beautiful and ornate. Unfortunately, when conditions are not ideal, occasional random leaves can die, shrivel up and go brown, all along its stem. This is unfortunate because, as explained, much of the beauty of the plants comes from the intricate, crystalline pattern of their leaves. However this disfigurement can be avoided by keeping the plants in optimal, fertile conditions – growing steadily and sheltered from stress. [图片]Propagation All Astrolobas can be propagated by seed, by cuttings/offsets, and by division of clumps. Cuttings or offsets should be dried for several days to weeks, in a cool, shady environment, before being planted in well-drained sand. Seeds should be collected and sown on well-drained soil. It is optional to cover them with a very thin, fine layer of sand. Keep moist until they germinate, and continue to water regularly until they are relatively large and strong. Keep in a bright spot, but out of direct sunlight. [图片]Hybrids can be made between all the Astroloba species (except for A. rubriflora, which has evolved a highly distinct chemistry in its flowers). Astrolobas can also be hybridized with other related genera, such as Tulista, Gasteria and Aloe.

Succulents are the perfect plant for forgetful and sometimes neglectful gardeners. They don’t require much care and are easy to grow inside as well as out. They come in a variety of colors and textures and look lovely potted or landscaped. [图片]Succulents are a diverse group of plants that come in many colors and shapes. There are over 20,000 varieties with kinds suited for all growing conditions. They store water in their leaves which tend to be thick and plump, although some have thinner leaves. They often grow in dry climates without much humidity. They do need to be watered, but can stand periods of drought instead pulling water that is stored in the leaves. They do not do well in wet conditions as their roots will start to rot if sitting in water for too long. Succulents often prefer warm weather can will not survive freezing temperatures. The stored water in the leaves will freeze and destroy the plant. Some species, however, can survive a freezing winter. The most common types of succulents that you’ll be able to find are Agave, Yucca, Aloe, cacti, Sedum, Sempervivum, Echeveria, Euphorbia, and even some orchids. [图片]Succulent Care As with all plants the four things to consider when caring for succulents are light, water, soil, and temperature. Light Both indoor and outdoor succulents generally need at least 3 hours of direct sun daily. Morning sunlight would be preferable as the afternoon sun can be too harsh. Some succulents that receive too much sun may be damaged and look sunburned with scars on their leaves or a washed out color. Especially in hot climates where the sun is the most direct be sure to keep your succulents in areas with filtered sunlight. Alternatively, succulents that don’t receive enough sun may begin to grow or reach toward the sun. The plants may begin to grow tall with the leaves more spaced out. Succulents that are colored may also turn green if not receiving enough light. Water Succulents are made to grow in arid climates and as a result do not need much water. They instead store their water in their leaves or stems. When watering your succulents be sure the soil is dry before you water. Soak the soil around the plant and don’t water again until the soil is completely dry. If the roots stay wet for long periods of time they may begin to rot causing the plant to rot. You will be able to tell this is occurring because the leaves will turn black and mushy and may start to grow mold. Generally, most succulents need to be watered only once a week. This will vary depending on your climate and soil conditions. If you are unsure how often to water your succulents it is better to underwater rather than overwater. Soil Well-draining soil is vital for succulents. This is important as too much moisture will cause the plant to rot. Unlike typical plants, succulent roots don’t absorb water through direct contact, but instead they get their water from the air. That is why well-draining soil is important. If you grow your succulents in pots, but sure the pot has drainage holes. When planting succulents look for cactus mix potting soil. This mix is designed to drain better than regular potting soil. If you are unable to find cactus mix you can make your own by mixing 1 part stone pebbles, 1 part wood mulch, and 1 part clay pebbles. The stone pebbles don’t absorb water and create pockets in the mix for the water to drain. The mulch and clay absorb moisture and slowly releases it allowing the roots to receive water. Temperature Most succulents are able to tolerate a large range of temperatures if they get the right amount of sun and water. However, the more delicate succulents should not be kept in temperatures above 95 degrees Fahrenheit (35 degrees Celsius) or below freezing. These are the types with really thick leaves. The extreme heat will cause them to droop when the soil gets too hot and dry and below freezing will freeze the water in their leaves. [图片]Propagating One of the excellent qualities of succulents is their ability to propagate easily. You can often start a new plant from leaf or a plant cutting. Some types of succulents propagate better from a cutting rather than a leaf. The succulents with the thick, fleshy leaves are best suited to leaf propagation. The best way to remove a leaf for propagation is to gently twist the leaf from the stem. You’ll want the entire leaf so nothing should be left on the stem. For succulents that propagate best from cuttings use sharp scissors or pruning shears and cut off a stem right above a leaf. This can be either the top of the succulent, or a new shoot. After removing the leaf or cutting you’ll want the end to dry out and scab over a bit before planting. If you plant it freshly cut it may absorb too much moisture. Depending on your climate and humidity this may take 1 to 3 days. The leaf or cutting may shrivel slightly. You’ll want to plant it before it dries out too much. When the end of the cutting is dry it is time to plant it. The leaf does not need to be planted and instead should be laid on top of soil. Mist the cutting or leaf with water whenever the soil is dry. You do not need to soak the soil. The leaves will begin to grow tiny roots within 4 to 6 weeks. When you begin to see roots cover them with soil so they don’t dry out. Propagating new plants from leaves and cuttings is not a quick process as it may take up to a year for the new plant to be fully grown. [图片]Identifying Often times when you buy a succulent at the store it may not be labeled. Or it will be labeled simply as “succulent” or “succulent variety”. This can be frustrating as different succulent have different growth requirements. There are many avenues you can take to help you identify your plant. The first may be to simply ask the seller. If they are unsure you may be able to identify your succulent with a photo using an online forum. The more difficult way to identify your succulent is to look at the characteristics of the plant such as leaf shape and growing habits. Leaf shape Succulents come in many shapes, sizes, and colors. The leaf shapes of succulent can vary greatly among the different kinds. Leaves are generally long and spikey or small and circular. Succulents that have long spikey leaves include Aloe vera, Agave, and Gasteria. Within the spikey-leaved category the leaves may be grass-like or fleshy. The succulents with circular leaves are rose-shaped, called rosette forming succulents. Rosette-forming, circular leaved succulents include Aeonium, Echeveria, and Graptopeltum. Rosette type Succulents that grow in the rosette-form feature close clusters of leaves that radiate from the center as a flower would. These leaves may be pointed or round, fleshy or grass-like. Jobivarva succulents feature rounded leaves and hen-and-chick feature pointed leaves. Configuration Some succulents grow in long stalks and others grow close to the ground and spread out. Succulents may change in configuration as they mature so waiting until they have aged may help in making an identification. Plant size The size of the plant may help you identify the plant as well as determine where it should be grown. Smaller plants, those that are just a couple inches tall and wide, may be best suited indoors. Larger plants may be best to grow outside. [图片]Flower shape and color Flowers are one of the easiest ways to identify a plant. If your succulent blooms pay attention to the shape, size, color, and even the time of year that it blooms. The Christmas Cactus, for example, blooms only once a year, in midwinter. Indoor Succulents Succulents are a popular choice for houseplants because they don’t require a lot of maintenance. A Jade Plant is a classic choice and is easy to grow. Aloe vera is also popular and can be used to treat sunburns or wounds. Burro’s Tail is a pretty plant that can add some interest to your interior. It has overlapping leaves which can reach up to 3 feet (90 cm) in length and hang over the flower pot. Christmas Cactus and Thanksgiving Cactus are succulents that bloom during the holidays and offer some color during the time of year when it can be hard to find. Keep this succulent outside in a sheltered area in the summer and fall. Bring it indoors when the overnight temperatures begin to drop into the 40s. Fertilize the plant three times during the summer and keep it drier in the winter than in the spring and summer. One of the easiest houseplants to keep is the Snake Plant. It gets its name from the shape of its leaves. This is an indestructible houseplant that strives on neglect. It grows upright and can fit into many locations in the home. There are also many varieties, some that are variegated in color, to offer many options. [图片]Outdoor Succulents The most common succulents you’ll find to grow outside are Yucca, Prickly Pear Cactus, and Agave. These plants are great for landscaping and can be used alone or for all of the landscape. Yucca and Agave are hardy for most of the United States. Hen-and-chick are a type of Sempervivum and get their name from the mother plant, or the hen, that produces cluster of offsets, the chicks. They are an easy plant to grow in the sunny part of the yard. They are low-growing and are also a good choice for a houseplant. When keeping it as a houseplant be sure to let the soil dry out completely between watering. Sedum, sometimes called Stonecrop, are a great succulent to use as groundcover as most types are low-growing. Some varieties are taller and look best in the middle of the garden. They grow well in a normal garden, but do best in drier conditions. They also grow well in full-sun or partial sun. [图片]Planting Succulents When planting succulents in your garden one thing you should pay attention to is the soil. If your soil is not naturally well draining you will need to mix in some sand or gravel to help the drainage. No succulents can tolerate standing water so well-drained soil is key. To help landscape the succulents consider adding a rock garden. This is a great way to achieve a natural looking succulent garden. Rock gardens feature various sizes of rocks and help mimic many of succulents native habits helping the landscaped succulents look more natural. You can also plant the succulents in groups to help them look purposeful and avoid planting in rows which can create the effect of soldiers in a row.
