The Mexican snowball is a horticulture species of the genus Echeveria in the family Chrysomelaceae. Mexican snowball is known as Echeveria elegans potosina. The leaves of the plant are closely arranged in an annular pattern, spoon-shaped, with small leaf tips, and the whole plant leaves are slightly closed towards the center. Smooth leaves of Mexican snowball are with micro white powder, leave all the year-round pale green, translucent leaf edge. When the temperature difference is large, the plant against the white powder on the leaves, is particularly lovely.
Mexican Snowball has strong habits and is easy to maintain. The suitable temperature is 10~25℃. During the spring growing season, the watering frequency can be 1-2 times a week. Summer should be an appropriate shade, pay attention to risk control water, overall maintenance is not difficult, summer is relatively easy.
Mexican snowball almost has no stem. Leaves of Mexican snowball are dense, oblong-obovate or obovate-cuneate, mucronate, upper surface flat or concave, 7 -- 7.5 x 1 -- 3.5cm, thick; Mexican snowball is almost white, or greenish frosted, sometimes with purplish edges.
Inflorescences are unbranched, 10 -- 15 cm tall, pedicels to 6 -- 10 mm.
Flowers: Sepals of Mexican snowball are 5 -- 10 mm, adnate or spreading, corolla tapered, 11 -- 18 x 8 -- 12 mm in diameter, pinkish to glaucous at the base, usually yellowish or green at the apex.
Mexican snowball is wildly distributed in Mexico Hidalgo, San Luis Potosi, Guanajuato, Queretaro, Jalisco and other places.
The spring and autumn season is the main growth period of Mexican snowballs. At this time, the temperature difference between day and night is big, the light is sufficient, the ventilation is good, especially the morning and evening dew is conducive to the growth of stone lotus. We can open doors and windows of the greenhouse, and removed the sun-shade net, to strengthen the light and increase the temperature difference between day and night, make it a more compact plant type, the white powder on the surface of the laid denser, the color of Mexican snowball is more bright-colored, otherwise Mexican snowball will lack light, the small temperature difference between day and night, cause the plant type is loose, and the red varieties cannot appear red, hairy varieties of hair grow thin, color and luster is dim, slender leaves thin, etc., these will affect their appreciation.
In the Mexican snowball growing season, we should master the "do not do not pour, pour then pour thoroughly" watering principle, avoid basin soil deeper, can rot root otherwise, but air humidity can be slightly bigger. When the air is dry, water can often be sprinkled around the plant to increase air humidity, but the leaf, especially the center of the leaf cluster, should not be water, so as not to rot. No matter when should avoid rain drench, especially long-term rain drench, otherwise the plant is bibulous overmuch, leaf, rhizome epidermis organization can be held by mesophyll organization crack, cause bacterial sex infection and rot. During the Mexican snowball growing season, apply decaying thin liquid fertilizer or "low nitrogen and high phosphorus and potassium" compound fertilizer every 20 days or so. When fertilizing, do not splash the fat water on the leaves. Fertilization is generally carried out in the morning or evening when the weather is fine. In the evening of the same day or in the morning of the next day, a flood is poured to dilute the residual fertilizer liquid in the soil.
In winter Mexican snowball should be given enough sunshine, if the minimum temperature at night at about 10 degrees C, and there is a certain temperature difference between day and night, can be properly watered, as appropriate fertilization, so that the plant continues to grow. If these temperatures cannot be maintained, control watering, keep the potting soil dry, stop applying fertilizer and put the plants to sleep. This will allow the plants to withstand temperatures of 0 ° C or even lower.
Turn the basin once every one or two years, in spring or autumn, the basin soil requires loose and breathable, with good drainage and appropriate granularity. It should be noted that Mexican snowball do not belong to fleshy root flowers, cultivation soil should not be too granulated, should choose about 1 mm, rich in humus fine sandy soil cultivation. Available leaf soil 3, 3 river sand, Garden soil 1, slag 1 mixed preparation, and mixed with a small amount of bone powder and other calcium materials, and sieving, sieving to too fine soil. When turning over the pot, cut off the old roots of Mexican snowball, cut the old roots short, and prune the old lignified coils appropriately to promote strong new roots. Replant with new soil. In order to be beautiful, still can spread a layer of stone or ceramsite and other granular material in the basin surface.
Propagation of Mexican snowball can be done by dividing plants, transplanting leaves, transplanting stems and sowing seeds.
Separating Mexican snowball can be carried out in combination with turning over the pot. The method is to take off the small plants that grow next to the old plants, but those with roots directly into the pot, and dry those without roots for a few days. After planting, they can survive.
Leaf insertion of Mexican snowball can be carried out in the growing season, take a thick and full of complete leaves, air 3 days to 5 days later, oblique insertion or flat in the soil, let the base and the soil closely combined, after spraying water in the half shade conservation, keep the soil half dry, soon the base will take root, and grow buds.
Cuttings of Mexican snowball can be cut with leaves of stem branches, some not easy to grow side bud varieties, the top of the rosette plexus can be cut, a few days after the cuttings, the remaining part is still in the soil, soon the residual stem will grow a lot of buds, such as these small buds grow up and then break off cuttings.
