Cultivation methods and precautions of Bletilla striata

How to cultivate Bletilla striata

soil

For potted Bletilla striata, you can choose moist soil with good air permeability, looseness, fertility and rich in humus. When potting, you can first fill some broken tiles at the bottom of the pot, then add leaf mold or garden soil mixed with some river sand, and apply some base fertilizer.

Light and temperature

Bletilla striata likes a warm growing environment, is cold-resistant and shade-tolerant but avoids strong light. When cultivating Bletilla striata, the suitable growth temperature should be kept at around 20℃. High temperatures in summer will easily cause yellowing of leaves, and the best overwintering temperature in winter is 5℃-10℃. Bletilla striata prefers a semi-shaded growing environment. In the hot summer, the light is strong, so it is necessary to pay attention to shading and keep it in a semi-shaded place.

Watering and fertilizing

Bletilla striata likes a humid living environment and is relatively fond of fertilizer. There must be sufficient water and fertilizer during the growth period. The soil should be kept moist and the air humidity should be kept at a high level. Water should be applied frequently during the growing season and water should be replenished in time during droughts. However, because Bletilla striata is not tolerant to waterlogging, it needs to be drained in time when it rains heavily.

There should be sufficient fertilizer. During the growth period, dilute fertilizer water should be applied once every half a month, and slightly more concentrated liquid fertilizer should be applied in August and September.

Things to note when breeding Bletilla striata

Reproduction method

Bletilla striata is usually propagated by tuber propagation. Dig out the Bletilla striata and cut it into several pieces with a knife, each with 1-2 small buds. It can also be propagated by seeds, but sowing is more difficult, so tuber propagation is more common.

Pests and diseases

Bletilla striata has fewer diseases and pests. The only disease it suffers is root rot, which is mostly caused by waterlogging. Pay attention to drainage. The pests are mainly cutworms and wireworms, which can be killed manually or by trapping, and pesticides can be sprayed when necessary.
