Culture methods and points for attention of Phyllostachys pubescens

1. Light temperature

The newly planted bonsai of Luohan bamboo is watered thoroughly and maintained in a shaded place for about 10 days, then in a half-shaded and half-sunny place for 5 days, and then carefully maintained in a sunny, ventilated, warm and humid environment. Because the pot is shallow and the soil is less, it is easy to damage the root system under the hot sun in summer, so it is necessary to cover the shade properly. At the end of autumn and the beginning of winter, when the lowest temperature at night drops to about 5 ℃, it should be moved indoors and the room temperature should be kept at about 8 ℃. Too high room temperature is disadvantageous to the growth in the coming year. In the south, as long as the pot is buried in the leeward soil of the sunny side, it can survive the winter safely.

two。 Watering requirement

Luo Hanzhu likes to be wet and afraid of stagnant water. After loading the basin, the water should be watered thoroughly for the first time, and the basin soil should be kept moist after that. Do not water too much, otherwise the root will rot easily. From the basin to the survival stage, we should also often spray water to the leaves. If the basin soil is short of water, the bamboo leaves will curl. At this time, the bamboo leaves will expand again if they should be watered in time. On average, it should be watered once a day in summer and less in winter, but the basin soil should be moist to prevent "dry freezing".

3. Fertilization requirements

Potted Luohan bamboo fertilizer is mainly organic fertilizer mixed into the basin soil when potting, appropriate topdressing after bamboo survival, "thin fertilizer is applied frequently", 0.5% urea or 1.0% compound fertilizer is applied in spring and summer.

4. Turn the basin and change the soil

It is generally appropriate to turn the basin and change the soil before the new buds grow in spring every year. The best ground cover is February. Tufted bamboo shoots because of summer and autumn, so it is better to shoot from March to May in spring. When turning the basin, cut off the curled root system properly and add new culture soil and base fertilizer. For overgrown plants, you can also change to a larger flowerpot in September. In order to make the plant shape of potted rubber trees plump, coring should be carried out when the seedlings grow to 60-80 cm high, in order to promote lateral bud germination. After the lateral branches grow, choose 3-5, and then cut the opposite lateral branches once a year, and you can get round and plump trees 1.5-2 meters high in 3 years.

5. Pest control

Potted Luohan bamboo pests are mainly aphids, shell insects, etc., can be sprayed with 1000 dichlorvos emulsion or 40% dimethoate emulsion; the main diseases are coal pollution, arbuscular disease, etc., it is necessary to strengthen management and prune diseased plants in time.
