What is the lowest cold-resistant temperature of Osmunda japonica Thunb?

Osmanthus fragrans has strong cold tolerance, the cold tolerance temperature is-12 degrees, and Lagerstroemia indica has the lowest cold tolerance of-15 degrees. Lagerstroemia indica will be frostbitten or even freeze to death when it is at-15 degrees for a long time. If it is maintained in the south, it can be maintained directly in the open air for the winter without special temperature control. If osmanthus fragrans is maintained in the cold northern region, it is best to move it indoors for maintenance.

Lagerstroemia indica, also known as itch tree and Jinger tree, is a deciduous tree. Lagerstroemia indica likes to grow in sunny places. The climate of the growing environment is warm and humid, and Lagerstroemia indica will grow better.

Is Osmanthus fragrans hardy?

Osmanthus fragrans has strong cold tolerance. Can accept the low temperature of-10 degrees. If osmanthus fragrans is maintained in the south, it can be maintained in the open air for the winter without special temperature control.

If osmanthus fragrans is maintained in the cold northern region, it is best to move it indoors for maintenance. Note that as long as the environmental temperature of osmanthus fragrans maintenance is between 0-5 degrees.

Cold resistance temperature of Osmunda japonica Thunb.

The cold tolerance temperature of Lagerstroemia indica is-12 degrees, and the lowest cold tolerance temperature of Lagerstroemia indica is-15 degrees. Lagerstroemia indica will be frostbitten or even freeze to death if it stays at-15 degrees for a long time.

The optimum temperature for Osmunda japonica is 15-40℃. Moreover, the minimum acceptable temperature of different Osmunda japonica varieties is different. Osmunda japonica can tolerate the low temperature of-10, and Osmunda japonica can tolerate the low temperature of -23.

How to plant wisteria in winter?

1, temperature

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.
