The cultivation method and precautions of Epimedium

1. Growth habits

First of all, it is a plant that prefers a cool environment, so light can be present, but it must not be too strong, especially direct sunlight at noon in summer. In addition, it needs water, but it is also afraid of waterlogging, so the water supply needs to be strictly controlled. Then there is the issue of fertility. Relatively speaking, it has a relatively high demand for fertilizer. There are also treatments such as loosening the soil and weeding.

2. Specific methods

Lighting: Normal astigmatism is acceptable. If it is planted in the woods, you can trim the crowns of nearby trees or build a shed. If it is grown in bare ground, you can also build a pergola, plant other crops next to it (corn, sunflowers, etc.) or take other shading measures. One to two-year-old plants have weaker light resistance, so it is better to control the canopy density at 0.6 to 0.7; three to four-year-old plants are slightly stronger, so it is sufficient to control it at 0.4 to 0.5.

Water: Generally speaking, the moisture content of the soil should be controlled within the range of 20 to 30 percent. If it is less than 15%, irrigation can be carried out; if it is greater than 30%, drainage must be carried out. Especially during the rainy season, drainage is particularly important.

Fertilizer: Foliar fertilizer can be applied in the first year after transplanting, once after the leaves unfold and once during the green fruit stage. The treatment is different after the second year of transplanting. In addition to foliar fertilization, root side fertilizer is also required.

Soil loosening and weeding: It needs to be done three times a year, the first time is after the seedlings emerge, the second time is in early June, and the third time is after the seeds are collected.
