First, screen out the seeds from the river sand, plant them in the seedbed, cover them with fine sand, and water them thoroughly with a watering can. The seedbed should also be covered with straw and the soil should be kept moist. After the seedlings are unearthed, the covered straw should be removed in time. When seedlings grow 4~6 true leaves, weeds should be removed in time and fertilizer and water management should be strengthened. In summer, a shed should be built to keep out the scorching sun.

Planting method of witch hazel

1. Soil selection: Hamamelis has low requirements on soil, and both acidic and neutral soils can grow. It is best to choose fertile and loose sand with good drainage.

2. Light and temperature: Witch hazel is both shade-tolerant and cold-resistant. Good illumination is needed for cultivation, and proper shade can be provided in the early stage of growth, and the temperature is kept between 65438 05℃ and 35℃. It can resist cold in winter and has strong cold resistance.

3. Water and fertilize: Hamamelis likes moist soil and needs fertility. Water properly during the growth period to keep the soil moist. Fertilization can be normal. Fertilization in early spring can promote growth, and phosphate fertilizer should be applied once when flowering.

4. Precautions: There will be diseases such as leaf spot and anthracnose in the breeding process, and the pests are mainly thorn moths and leaf curl moths, so we must pay more attention.

Propagation method of witch hazel

1, sowing and seedling raising

After the fruit is ripe in autumn, collect the fruit branches and put them in the sun for 2-3 days. The fruit will crack automatically, and the seeds will be taken out for sowing. After sowing for about half a month to twenty days, the seeds basically germinate. Choose a time when the light is not very strong and uncover the grass.

In addition, it is necessary to loosen the soil, weed and topdressing. And pay attention to water and fertilizer management to cultivate healthy seedlings. During the period from defoliation to germination in the following spring, the seedlings were transported, and bare roots were planted or transplanted to complete the final planting.

2. Other copying

In the propagation of witch hazel, seeds are often used to sow and raise seedlings. Grafting, cutting and other methods are also possible, but their reproductive survival rate is not as good as sowing, so they are rarely used.

How to prune witch hazel

1. First of all, when pruning witch hazel, you should cut off some unnecessary branches, such as tillering branches and crowded branches, to make it look fresher and less messy.

2. Secondly, after the witch hazel blooms, attention should be paid to picking off the fruits and flowers. However, even if the witch hazel does not pick the fruit, it will not have much impact on its plant growth.

The most important thing is to adjust the tree shape of witch hazel. First of all, we should observe the growth of witch hazel, trim it on the premise of maintaining the overall balance, cut off the external branches and branches that affect the appreciation, and narrow the crown. If we want to keep the original height or the original tree shape, we can cut off the trunk of witch hazel that stretches so high.

The cultivation of witch hazel is relatively simple, and the common breeding method is sowing, but it still needs a little skill to grow better. Pruning is an important factor affecting its growth, and pruning after flowering is more effective.
