The methods are as follows:

Summer Gastrodia elata planting and management skills

1. Gutter drainage

When Gastrodia elata enters its vigorous growth period, it is time to start checking whether the drainage ditches in the cultivation site are waterlogged and unobstructed. The soil moisture content can be between 60-65%. July, August and September are the months when Gastrodia elata needs the most water. During this period, be sure to check and clean the drains in time to avoid water accumulation.

2. Cover and moisturize

Technical measures for cooling down. The mulch can be made of fallen leaves of broad-leaved trees (leaves of pine, cypress, camphor, etc. can also be used), grass, with hairy grass being the best, but rice straw, corn stalks, etc. can also be used.

If you check for pests such as termites, you should use trapping and killing methods to eliminate the insects. For example, bury pine wood beside the cultivation ditch box to lure termites and kill them with pesticides.

5. Add nutrition to increase production

Generally, no nutrients are required during the growth period of Gastrodia elata. In recent years, some people have sprinkled potato juice into the cultivation holes of Gastrodia elata and found that it can increase the yield by 10-15%.
