Produce indoor greenhouses to cultivate succulents haworthia cooperi var

Morphological characteristics

Succulent perennial herbs. The plant is 5-16cm in height. The plant is solitary at the beginning, and then gradually presents
group growth. The fleshy leaves are arranged in a rosette shape, with green color and transparent or translucent top, which is
called "window". There are dark vertical lines on the surface and small "whiskers" on the top (commonly known as "top hair", which
is not found in some horticultural jade dew). Loose raceme with white florets and longitudinal green stripes. It blooms at the end
of spring.

Cultivation Techniques

During the growth period of Yulu, the soil should be kept moist to avoid ponding and rain, especially for a long time, in order to
avoid rotten roots; But it is not suitable for long-term drought, otherwise the plant will not die, but the leaves are withered,
the color of leaves is dim and lack of vitality. Yulu likes the environment with certain air humidity. When the air is dry, it can
often spray water on the plant and the surrounding environment to increase the air humidity. In the growing season, it can also
cover the plant with a transparent colorless beverage bottle with the upper part cut off, so that it can grow in the small
environment with humid air. This can make the leaves full and the transparency of the "window" higher. But in the high temperature
season in summer, we must remove the drink bottle, so as to avoid the plant death due to hot and humid. During the growing period,
the plants with vigorous growth should be applied with decomposed thin liquid fertilizer or compound fertilizer with low nitrogen
and high phosphorus and potassium once a month, while the plants with new growth or weak growth should not be applied with
fertilizer; Fertilization is not necessary during the dormancy period when the temperature is high in summer or low in winter. The
fertilization time should be in the morning or evening when the weather is fine[ 5]
In summer, the plant is dormant or semi dormant, and its growth is slow or completely stagnant. It can be maintained in a
ventilated, cool and dry place, so as to prevent the plant from "steaming" to death in a muggy and humid environment, and avoid
the sun exposure. Do not pour too much water, stop fertilization, and return to normal management after it is cool in autumn. In
winter, the lowest temperature is about 8 ℃ at night and above 15 ℃ during the day. The plants can continue to grow and should be
watered normally; If water is controlled to make the plant dormant, it can endure low temperature of 3-5 ℃ or even short-term low
temperature of 0 ℃. If the plant is in low temperature environment below 5 ℃ for a long time, it will not die, but there will be
traces of frostbite on the leaf surface, and even the peripheral leaves will freeze to death. Therefore, it is better to keep the
overwintering temperature above 5 ℃[ 5]
For the robust growth of Yulu, change the basin once a year in spring or autumn. If the plant growth is stagnant and the leaves
are shriveled during the growth period, it is likely that the root system is damaged, so it is necessary to turn the basin to
clean up the root system in time. When turning the pot, the aged and hollow roots are cut off, the long roots are cut short, and
the thick white new roots are retained, and then planted with new culture soil. The newly planted plants can spray water
frequently, but they should be watered less each time, so that the plants can recover as soon as possible. The soil should be
loose and fertile, with good drainage and air permeability, calcareous and coarse granular matrix. It is usually planted in the
mixed soil of 2 parts of rotten leaf soil or peat, 3 parts of coarse sand or vermiculite, and mixed with a small amount of bone
powder. The ornamental value of Yulu flower is not high. If the seed is not reserved, the flower can be pulled out from the base
to avoid consuming too much nutrients. It should be noted that the flower stem should not be cut with scissors, but should be
pulled out by shaking left and right hands, so as to avoid the residual flower stem remaining between leaves, causing adverse
effects on the growth of new leaves in the future[ 5]
Poor soil permeability, long-term waterlogging easily lead to rotten roots, plant rot caused by central waterlogging, long-term
drought or other causes of root atrophy, no new roots, unable to absorb nutrients and water, resulting in plant growth stagnation,
withered leaves, can improve the cultivation environment for prevention, if there are signs of rotten plants, to deal with in
time, remove the rotten parts, And daub carbendazim on the wound, then air it until the wound is dry. For completely rotten
plants, check whether there are still relatively complete leaves (especially the base must be complete). If there are, dry the
base and then carry out leaf cutting propagation[ 10]

About 10 cm

Main value

Yulu is one of the small succulent plants with exquisite plants, rich varieties, crystal clear leaves, moist and fresh, just like
a living handicraft. It is suitable for planting in small pots or making horticultural scenery boxes to decorate windowsill, desk,
desk, balcony, etc.

Introduction to Plants

Native to South Africa. It likes cool semi shade environment, and grows mainly in spring and autumn. It is resistant to drought
but not cold. It should avoid high temperature, humidity and sun exposure. It is afraid of shade and soil ponding. The sandy loam
with loose air permeability and smooth drainage is suitable.

Reproduction modum

Ramet
It can be carried out in combination with changing pots, or the young plants beside the mother plant can be dug in the growing
season. Both rooted and rootless plants can survive. Those with roots can be planted directly, and those without roots should be
dried for 1-2 days before planting. The newly planted plants should not be watered too much, so as to avoid rot. after the new
roots grow, the normal management should be carried out[ 5]
cuttage
In the growing season, the selection of robust and full fleshy leaves requires complete base. After the leaves are taken off, they
are allowed to air for 3-5 days. After the wound is dry, they are inserted into the substrate. Later, the basin soil is kept
slightly moist. It is easy for the base of nephew to take root and grow small buds. When the small buds are slightly larger, they
can be planted separately[ 5]
sow
Seeds can be obtained by artificial pollination and sown in autumn or spring. The sowing soil can be mixed with vermiculite in 3
parts and rotten leaf soil or peat soil in 2 parts. It is best to disinfect the soil with high temperature before sowing. The
seeds were covered with glass and emerged about 20 days after sowing. Remove the glass after emergence, pay attention to
ventilation, do not make the soil too dry, when the seedlings are overcrowded, pay attention to transplanting. Some variation
plants may appear in the seeded seedlings. The young plants with larger plants, compact plant type, fleshy leaves, high
transparency of "window" and obvious veins can be selected as the seedlings for preservation[ 9]
