Succulents are group of plants that have fleshy leaves, stems or roots designed for storing water and allowing the plants to survive periods of drought. Whether your succulents grow in containers on a patio, as groundcovers between the pavers in a garden path or as colorful and interesting accents in a garden bed, they need a growing medium suited to their capacity for retaining water.[图片]Soil Requirements Although succulents retain moisture well, they do still need moderate to regular watering, at least once a week or a deep soaking every few weeks during the growing season. But too much water will cause the roots to develop black stem rot, so the trick is finding a growing medium that drains quickly and dries out completely between watering. Succulents do best with soil that is normally considered poor, filled with inorganic elements, as opposed to one rich in organic material.[图片]Organic and Inorganic Elements Despite their need for well-draining soil, succulents do need some nutrients that organic elements provide. Some gardeners recommends a mix of 1 part garden soil, 1 part sand and 1 part peat moss or a mixture of 1 part potting soil and 1 part perlite. Other gardeners avoid potting mixes containing peat, remove any wood and twigs from the mix and add a coarse, gritty type of sand to potting soil.[图片]Testing the Soil Using sand, pumice, decomposed granite or perlite as the inorganic element in your succulent growing medium is less important than simply ensuring that the soil crumbles easily and lets water flow quickly through. If your soil falls apart after you wet it and give it a squeeze, it has the right components. If it remains formed into a lump, it needs more inorganic elements added to the mix.[图片]Other Growing Medium Needs The best soil for succulents is slightly acidic with a high lime content. If a soil test kit determines that your soil is highly acidic, your plants will benefit from some horticultural lime added to the soil. If your soil is overly alkaline, change the balance by watering with a solution of 1 tablespoon of white vinegar added to 5 gallons water. Top off your growing medium with a layer of gravel or small river rock to keep the tops of the plants dry.

Succulents are plants that store water in their tissues, enabling them to live in severe environments such as a desert. Many succulents thrive with full sun exposure. Once some varieties become accustomed to a low light environment, however, they can remain there indefinitely as long as they are cared for properly. Because succulents retain moisture in their thick foliage, they require soil that drains well and less water than typical houseplants.[图片]Mason’s Congo Originating in central Africa, Mason’s Congo (Sansevieria masoniana) can grow up to 5 feet (1.5 m) tall by 2 feet (60 cm) wide. As an indoor plant, it requires little light or water. Its wide, dark-green leaf stalks are covered with lighter green spots, providing a statement in any office, and the plant is simple to maintain. Mason’s Congo is hardy outdoors in U.S. Department of Agriculture (USDA) plant hardiness zone 10.[图片]Jade Plant The Jade Plant (Crassula ovata) is a popular indoor plant. It requires minimal watering and is known in Japanese folklore as the Money Plant. According to legend, it can lead to financial success. The thick trunk and branches give this plant a tree like look similar to a bonsai tree. If planted outdoors, the jade plant is considered a perennial succulent, thriving in sunlight to partial shade in areas where it is hardy, USDA zones 10a to 11a.[图片]Gasteria The Gasterias (Gasteria sp.) grow well indoors. Similar to the Aloe plants, Gasteria has long, spiny, green leaves that grow in a rosette or spiral form. The leaves are spear-shaped and, as true with all succulents, swollen with water-storing tissue. Gasteria is named for its stomach-shaped flowers. The largest Gasteria grows up to 2 feet (60 cm) tall. Gasteria is hardy outdoors in USDA zone 11 in sandy soil.[图片]Zebra Plant Zebra Plant (Haworthia fasciata) doesn’t take up much room and needs even less care. It’s the ideal succulent for busy lives. Hailing from South Africa, plants perch on soil and sport a tidy form with leaves that boast striking horizontal white stripes. Zebra Plant is hardy outdoors in USDA zones 9 through 11.[图片]Aloe Vera Perhaps the most commonly known succulent is Aloe vera. It can be grown in low-light environments, although it thrives in sunlight. Aloe vera is hardy outdoors in USDA zone 9.

Succulent plants that have been just moved from a shady location to direct sunlight are likely to get sunburn. Sunburn on a succulent shows the worst damage at the top and side that is facing the sun. Ridges are more likely to burn than valleys along the plant stem. Sometimes, cacti have wide ribs and little spine protection and then sunburn will occur in between the ribs. A light burn will just be a whitish discoloring on the exposed areas. More severe burns will become a hard brown scar along the plant in whatever areas did not get shaded by spines or other parts of the stem.[图片]Treatment If you catch a sun burned succulent at the whitish discoloring stage, you can undo the damage by getting it some shade protection. If the plant gets to the brown scaring stage, then the damage is permanent and the plant will have to grow out of it in time. Again, prevention is the best defense with sunburn.[图片]If you purchase a plant that has been sitting inside a store for some time, you will need to gradually move it into full sun. Do this by giving it full sun for a short period of time each day, and then regularly increase the length of time in the full sun over the course of a couple weeks. Keep in mind that some species do not ever want full sun all day. Also note that “full sun” in England is much different than “full sun” in Arizona. The stronger the sun where you live, the more careful you have to be to keep your plants sun burn free.[图片]

下面要介绍的就是一种非常耐寒、耐阴的观赏花卉，它的花朵长得一串串的，每一朵都像是一颗正在滴着血的心脏，花朵一般都是红色或粉红色，也有部分是白色的花，看起来十分非常神奇的。 [图片]#荷包牡丹 在我国野生的也有，不过现在经过不断的园艺品种的开发，已经有很多适合盆栽或地栽养护的品种。 荷包牡丹最大的特别就是喜欢遮阴的环境，如果你家里有阴凉的地方，那么栽种荷包牡丹就是不错的选择，还能和玉簪、蕨类植物搭配栽种，秋季栽种，来年春暖之后就能开花了。 [图片]栽种荷包牡丹非常简单，还不用经常照顾，以前都是一些有钱人家种在别墅里面的，不过现在已经变成众多花友青睐的花卉。 栽种荷包牡丹的环境不能有太充足的光照，每天最多只能有2~3个小时的散射光，过多的光照容易晒伤。 除了养护的光照问题，栽种荷包牡丹最重要的，就是保证栽种的土壤有良好的排水性，一定不能积水，不然很容易烂根烂茎。 [图片]可以看到上面这些荷包牡丹长得都非常葱郁，在阴凉的角落也能开出靓丽的花朵。 荷包牡丹对环境的要求并不高，只要保证土壤的排水性，加上通风微润的环境，就能让它保持良好的生长。 养护荷包牡丹虽然不能让土壤积水，但是也不能让土壤过于干旱，养护期间就是要保持盆土适当微润，微润而不积水，才是最佳的养护方式。 开花之后可以对荷包牡丹的植株进行适当的修剪，这样可以由于保留养分，这样可以让它保持良好的株型，而且会更加容易越冬。 [图片]栽种荷包牡丹的土壤一定要疏松透气和排水良好，肥力的大小并没有太大的关系，栽种的时候可以在土壤里适当添加腐熟的有机肥，其他季节基本不用施肥，不过为了促进开花，可以在3~4月的时候适当补充缓效性的肥料。

Aloe aristata, also known as Lace Aloe, is a small hardy succulent plant popular as an indoor plant. It is a stemless, up to 12 inches (30 cm) tall, clump-forming succulent with dense rosettes of stubby, lance-shaped, toothed, white-margined, dark green leaves, up to 4 inches (10 cm) long, with small white spots and soft white spines, particularly beneath. In the fall, produces terminal panicles, up to 20 inches (50 cm) tall, 2 to 6 branched, bearing cylindrical, orange-red flowers, up to 1.5 inches (4 cm) long.[图片]Growing Conditions Light: Bright light suits Aloe aristata. It will not thrive if permanently placed at a distance from a window. Soil: Dry and well drained gritty soils are suitable for these plants. Sandy free draining soil will keep the Aloe aristata healthy. Use cactus compost or add sand to improve the garden soil drainage.[图片]Temperature: Aloe aristata plants grow well in normal room temperatures and are tolerant of dry air. To encourage flowering, however, it is best to give the plants a short winter rest at a temperature of no more that 50°F (10°C). Watering: During the active growth period water plentifully as often as necessary to keep the potting mixture thoroughly moist. During the rest period water only enough to prevent the potting mixture from drying out. Do not permit water to collect in the tight rosette. Fertilizing: Feed Aloe aristata very little now and then during the active growth period.[图片]Potting and Repotting Use a soil based potting mixture. Most Aloe aristata should be moved into pots one size larger every spring. Keep these plants in shallow pots. When maximum convenient pot size has been reached, plants should be top dressed with fresh potting mixture once a year. To prevent rot, make sure that these plants which have tick basal leaves are never buried deeper than they were before. A sprinkling of coarse sand over the surface of the potting mixture helps to prevent rot points where fleshy leaves of these stemless plants touch the soil.[图片]General Care In order to grow Aloe aristata in temperate climates they will need to be taken inside during the coldest weather and keep them in bright sunlight during the summer. This species is hardier than many other species within its genus, but will still appreciate the warmth. It requires very little maintenance, making it an ideal choice for novice gardeners. They flower freely in the summer and the soft-orange flowers are a wonderful addition to the arid garden. This genus is well known for its ease of cultivation, but they are sensitive to excessive irrigation. Provide regular watering in spring and summer to make the soil thoroughly moist then allow the soil to dry before watering again. In winter (during the dormant season) water sparingly or not at all, as it is prone to rotting; a thin layer of gravel on top of the soil will help to prevent this.[图片]Propagation Aloe aristata produces offsets that can be taken from the base of a plant early in summer. These small new rosettes are often attached to the parent by a short underground stolon and may already have little roots, which should be retained for propagation propose. Because very tiny offsets are hard to root, they should not be removed for planting until their leaves have begun to open into the characteristic rosette shape. Offsets will root in two to three weeks in the standard potting mixture if some coarse sand is sprinkled at the base of the rosette to prevent rotting. Until offsets are well established, they should be provided with bright light without direct sunlight and they should be watered only enough to moisten the potting mixture, allowing the top two-thirds of the potting mixture to dry out between waterings.[图片]Also, Aloe aristata can be propagated by seed sown in warm environment as soon as ripe. Pests and Problems Most likely to be caused by incorrect watering. A properly watered Aloe aristata plant can resist most pests and diseases. Wilting is the result of inadequate water in summer. Yellowing leaves accompanied by rotting at the base is the result of overwatering plants kept in cool winter conditions.[图片]Mealy bugs and root mealy bugs ca be troublesome. The former hide deep in the crevices of rosette foliage and the latter generally bury themselves in the roots, just below the surface of the potting mixture. Treatment: Remove visible bugs with a toothpick or a damp cloth or swab them off foliage with a small, stiff paintbrush dipped in methylated spirit or an insecticide solution. Then spray all top growth with an appropriate pesticide. Alternatively, place granules of a systemic pesticide in the potting mixture. During the next month examine plants weekly for traces of reinfestation.[图片]Scale insects can also infest this plant. Treatment: Scale can be easily controlled by physical removal, wash off with high pressure jet of water or scrape off with cotton wool buds or by chemical control with appropriate pesticide.

植物叶子变黄是有很多的原因引起的，如果你能及时发现原因，那么很快就能让植物恢复健康，如果原因不明显，那么就要多尝试几种方法才能解决问题了，如果你在植物刚开始黄叶的时候不管，那么很容易整棵植株变黄或枯萎。 #黄叶 之后及时处理，很快植物就会恢复健康，新的叶子长出来之后，植物还是可以正常开花的。 以下是黄色叶子最常见的6个原因： 1、给水不适宜 过度浇水或浇水不足是造成植物叶子变黄的最主要原因，每次浇水之前，都要检查土壤是否还是湿湿的，只有等盆土比较干之后才能再次浇水，如果土壤经常是湿湿的，即便是喜水的绿萝，也很容易烂根烂茎。根系积水，就不能进行呼吸，容易导致根腐病。 [图片]如果植物不能吸收到足够的水分，它的叶片就容易变黄变干，植物生长需要消耗水分，如果根系没有水分，首先的就是消耗叶片，如果没有及时补充水分，就容易越黄枯萎，如上图的孔雀竹芋。 如果不知道植物什么是该浇水，可以用盆土干透浇透的方法。 2、叶片正常老化 [图片]盆栽植物慢慢养护一段之间之后，在根茎底部的叶子就会慢慢变老，这些叶子不可避免就会变黄，这些就是植物的正常消耗，只有消耗了底部的叶子它才能不断长高，在这样的情况下，可以考虑及时摘掉这些黄叶，避免过多的养分消耗，这样也能促进植物更快更好的生长。 3、植物受冻 [图片]热带植物在北方地区就很容易受冻，一旦受冻首先的症状就是叶片变黄了，这和植物短时间暴露在寒冷的环境中的状况是不同的，这会导致植物的叶片彻底变成褐色，而且叶片的叶脉上会出现苍白的透明白点。 这个时候就要将盆栽植物慢慢搬到温度更高一点的地方，但是温差不能超过10度，不然温度一下子变化太大，对植物的恢复是非常不利的。植物也要避免放在空调的出风口或暖气上。 4、光照不适宜 [图片]养护盆栽植物不能频繁搬动，而且不能一下搬到环境差距过大的地方，如果是已经适应遮阴环境的植物，想要让它见光，就不能一下给过多的光照，只能先让它适应微弱的散射光，之后慢慢增加光照。 盆栽植物切记不要频繁搬动，植物适应一个新的环境需要一段时间，花果期更是少搬动。 5、营养不足 如果植物的顶部叶子变黄，叶子黄化得比较异常，而且日常的浇水和见光都是没有问题，也没有病菌感染，那么就是植物缺乏营养了，有部分是土壤偏碱造成植物的叶片变黄，长期直接用自来水浇花容易让土壤板结和偏碱，植物缺氮也是叶片黄化的主要原因。 这个时候可以适当补充硫酸亚铁，改善土壤酸碱度，土壤结块的要适当松土，添加有机液肥补充土壤的有机质和各种养分。 6、病菌感染 [图片]植物如果是病菌感染造成的叶黄，那么叶片上首先出现的就是斑点，如果不及时处理，植物叶片上的斑点就会慢慢扩散成黄色的斑块。 之后植物还会出现变形的茎叶，如果没有及时治疗植物的病叶，还容易传染给周围的叶片，甚至传染给旁边的植物。 发现病叶之后要及时清除病叶，盆内也不要留有残叶，之后要定期喷百菌清或托布津进行防治，每周一次，喷3~5次就能痊愈了。

Sempervivum arachnoideum, sometimes known as Cobweb Houseleek is a species of flowering plant in the family Crassulaceae, native to the Alps, Apennines and Carpathians.[图片]It is a low-growing, evergreen, perennial succulent, forming a mat of fleshy rosettes up to 1.2 inch (3 cm) in diameter. Leaves are green or reddish, with cobwebby white hairs at the tips. Starry pink flowers are up to 0.4 inch (1 cm) in width in flat cymes on stems up to 5 inches (12.5 cm).[图片]Growing Conditions Light: Full sun to light shade Hardiness Zones: 4a – 8b Soil: Sempervivum arachnoideum, as with most succulents, need excellent drainage. Poor, sandy soil would be just fine. You could work some peat into heavier soil, to lighten them and improve drainage. Water: Regular in growing season, very little in winter.[图片]Propagation Propagate by seed sown in spring, or root offsets in spring. General Care Relatively easy to grow in container or in rock garden, scree bed, wall crevice, trough or alpine house. After the plant blooms and sets seed it will die, but there will be many offsets to take its place. Plant in well drained succulent soil mix in full sun to light shade. Water regularly during the growing season and allow soil to dry out before watering again. Water very little during the winter months.[图片]Pests and Problems Sempervivum arachnoideum can get vine weevil and may be subject to a rust.

Crassula ovata (also known as Jade Plant) care is easy and simple. Many people enjoy growing Jade Plants in their homes and offices, and they are considered to be symbols of good luck. But you do not need to be lucky to learn what the proper care and maintenance of Jade Plants is. Keep reading to learn how to care for a Crassula ovata.[图片]Learning about the care and maintenance of Crassula ovata is easy. The most important factors to consider when growing jade houseplants is water, light, temperature, and fertilizer.[图片]Growing Conditions Light: Crassula ovata flourishes in good health with plenty of light. If you can provide a few hours of sunshine a day your going to have a happy plant. Soil: A good draining soil mix that is gritty is advisable to use, which is sold and used for cacti and succulents. Temperature: Room temperatures of around 60°F to 75°F (15.5°C to 24°C) are ideal. Winter no less than 50°F (10°C).[图片]Hardiness Zones: 9b – 11a Watering: It’s best to allow the soil to become dry between each watering which will depend on the time of year, how much humidity and amount of sunlight it’s getting. Allowing too much water to sit at the bottom of the pot with the roots will cause them to rot (avoid this). Fertilizing: Feed each week or two (maybe less) with a weak or diluted liquid fertilizer. Fertilizer made for succulents may be your best bet, that does not need to be a high strength type.[图片]General Care Easy to grow in container, best in full sun but will tolerate part sun. It need well-drained soil with a neutral pH. Water regularly form spring to autumn and allow soil to dry out before watering again. During the winter months, water only enough to keep the leaves from shriveling. Most common reason for failure is overwatering![图片]Propagation Propagating is achieved with leaf or stem cuttings which are placed into a soil mix, then wait until they show some growth. Before placing them in soil mix you will prevent potential problems from the sap seeping out by allowing them to dry on a windowsill, for a few days or so.
