How to raise wisteria in winter

Pay attention to the adjustment of temperature in winter. The cold tolerance of seedlings is poor, so it is necessary to do a good job of cold protection and heat preservation of seedlings. We shouldn't put Osmunda japonica in the environment after 5 degrees, otherwise it will die because of the low temperature. The grown Lagerstroemia indica plants have strong cold resistance, and the heat preservation can be stopped after more than three years of culture.

2. Water and fertilizer

In order to fight drought and avoid waterlogging, Osmunda japonica can be watered once a year before germination in spring, once with frozen water after defoliation in autumn, and pay attention to "no watering" at other times. In addition, we should pay attention to fertilizer and water management in winter and apply fertilizer once after defoliation in autumn. Fertilization should be stopped in winter, because Osmunda japonica is dormant in winter, and there is little demand for water and fertilizer at this time. Excessive application will kill Osmunda japonica.

prune

In winter, Lagerstroemia indica will enter the dormant period, and then pruning will be carried out after the dormant period to ensure the appearance of Lagerstroemia indica. In the process of pruning Osmunda japonica Thunb, the pruning of branches should have a layered feeling, so as to avoid the cross of seedlings after growth and look more layered, and at the same time, it is necessary to ensure that there are a small number of buds on the trunk. You can also cut off dead branches, overlapping branches and too dense branches, and then leave old branches about 10 cm.
