[culture methods and matters needing attention] how to cultivate cold water spray

Cold spray is a kind of small potted indoor foliage plant with beautiful leaves. Like yin, suitable for small and medium-sized pot cultivation. It can be cultivated and ornamental all the year round in a brighter room. It can be suspended or placed on flower racks, corners or coffee tables, and it is also a rare ground material for decorating indoor gardens.

I. the culture method of cold water spray

The main results are as follows: 1. The cold water spray changes the pot soil once a year in spring, and the soil is cultivated with foliage plants.

From February to October, rarefied liquid fertilizer or granular fertilizer should be applied once a month. Pay attention to the fertilizer can not touch the leaves, after fertilization, it is best to sprinkle with water, rinse the leaves.

3. Mesophytic flowers should also spray water to the leaves every day in summer. Do not spray the leaves in winter to avoid black spots.

4. The cold spray needs good light, but the end avoids the strong light.

5. Keep the room temperature above 0 ℃ in winter.

6. Before sprouting in early spring, combined with turning the basin and changing the soil, the taller old branches were re-pruned to promote the growth of new branches so that the plants could be renewed.

II. Matters needing attention in the culture of cold splash

Change the basin at least once a year in spring, fertilize in about a week during the growth period, and fertilize once with a nutrient solution. The cultivation time is too long, when the growth is slow, it should be pruned and renewed in time. Otherwise, the ornamental effect will be reduced.

Cold spray likes strong scattered light, covering more than 70% of the sun in summer.

No shading or slight shading is needed in winter.

When overwintering, the temperature should be above 13 degrees Celsius. If the long-term temperature is lower than 10 degrees Celsius, the flower branches will be hurt. But about 5 degrees Celsius in a short period of time, there will be no harm.

Cold spray likes a humid environment and often keeps the spray moist and high air humidity. In the dry season, you can often spray water to the surrounding environment or foliage.

Third, the maintenance of cold splash

Sexual preference for warm, humid and semi-shady environment, fear of direct light, it is appropriate to be rich in humus and loose, well-drained soil. Pot culture should be made of rotten leaf soil or peat soil and garden soil mixed with about 1 to 5 river sand or perlite and a small amount of rotten cake fertilizer. The basin is usually changed every spring. Rarefied liquid fertilizer is applied once a month during the peak growing season. If too much fertilizer is applied, it is easy to cause overgrowth of plants. Watering should be "dry and wet" and do not accumulate water.

In spring and autumn, it is appropriate to put it in a semi-overcast place. In summer, it is well ventilated and there is bright scattered light. In winter, it is on the windowsill facing south. If there is not enough sunlight for a long time, it is not only easy to cause longer internodes, soft stems and loose plant shape, but also thinner leaves and lighter leaf color and lose luster. Reduce fertilization and watering after autumn. The suitable temperature for growth is 15-25 ℃, and the room temperature in winter should not be lower than 5 ℃. During the overwintering period, fertilizer should be stopped and watering should be strictly controlled.

Cold water, this planting object is small and green and beautiful, the animals and plants are slightly shocked when the flowers are in bloom, and the pollen that pops out is like a mass of fireworks, and the landscape is very beautiful, so it enjoys the good name of "fireworks and plants" in America, which can be used as cultivation and ornamental.
