How to easily plant old Lagerstroemia indica piles and survive?

Pile material treatment: Prune the rotting roots of Lagerstroemia indica old piles after excavation, and apply rooting powder after a little recovery. Substrate selection: the mixed nutrient soil of river sand, humus soil and garden soil is planted in the treated old pile. Planting and maintenance: water immediately after planting and maintain in a ventilated place. Trim the shape: Trim it in the spring of the following year.

How to plant 1 and treat old Lagerstroemia indica piles

If you want to plant live Lagerstroemia indica old piles, you need to dig them when the leaves are dormant in winter. At this time, the leaves fall off completely, the ambient temperature is low, and the evaporation rate of plant water is slow. Protect the root system when digging, keep as many fibrous roots as possible, which is beneficial to the survival of plants, trim the rotten root system, and apply rooting powder after a little recovery.

Step 2 Choose a substrate

When planting Lagerstroemia indica old piles, the soil requirements are high, and the garden soil can not be directly used for planting. River sand, humus soil and garden soil are mixed to make nutrient soil with drainage, air permeability and certain nutrients. After being disinfected with potassium permanganate, they are laid in flowerpots, and the treated old piles are planted in the soil.

3. Planting and maintenance

Old Lagerstroemia indica piles need to be watered immediately after planting, so as to keep the soil moist, promote the root system to absorb water and speed up the recovery. They should be kept in a position where light is scattered and ventilated. In the later period of maintenance, water the soil when it is completely dry, and avoid light when the light is strong, so as to avoid rapid evaporation of water.

Step 4 trim the shape

After the old pile of Lagerstroemia indica resumed growth, it was reshaped with sterilized scissors the following spring. According to the growth of the old pile, trim it, cut off weak and dense branches, and cut short steep branches to make it flat and shaped. After molding, adjust water and fertilizer to control growth.
