Red maple is a variety of Japanese maple (Acer palmatum). There are many cultivars, with graceful leaf shapes that are palmately 5-7 lobed, long-lasting red color, neat branching order, distinct layers, and a light and elegant tree posture, so it is widely cultivated. The earliest cultivation in China should have been in the Zhejiang area. Red maple is a very beautiful foliage tree species, with red branches and leaves that are dazzling, and its ornamental value is very high. Many people choose to grow potted red maples at home for appreciation.

The branches and leaves of red maple are graceful in shape, and the fiery red color can remain bright and lasting. It is a very suitable ornamental plant for indoor placement, and it will be a distinctive scenery in the room. Here is an introduction to the spring planting and management of red maple trees:

[Land Preparation]

Deeply plow the land where red maple trees are to be planted, then spread organic fertilizer. Use about 2 cubic meters of organic fertilizer per mu as the base fertilizer needed for the growth of the seedlings that year. At the same time, carbofuran soil insecticide can be used to eliminate underground pests, and then a rotary tiller can be used to rotary till the soil, so as to achieve good looseness of the soil before planting.

[Planting]

1. Before planting the seedlings, prune the root system of the red maple saplings to be planted to promote the growth of the red maple seedling root system. At the same time, dip the roots in a fungicide, generally using carbendazim or thiophanate-methyl diluted about 500 times, dipping the roots for about 20 minutes. When dipping the roots, a small amount of fungicide can also be applied to the stems of the seedlings.

2. When planting red maple seedlings, plant them according to the predetermined spacing between plants and rows. After planting, the seedlings need to be lifted slightly so that the red maple seedling roots can spread out better.

3. After planting the red maple trees, water them promptly, preferably three times in a row, with thorough watering. Ensure that the red maple seedlings and the soil are fully compacted and that there is sufficient water.

[Watering]

Red maple likes moisture during its growth process, but aside from sufficient watering in summer, watering at ordinary times should not be excessive. It is best to keep the potting soil moist regularly, as this helps maintain a graceful tree posture.

[Fertilizing]

From May to August each year, generally apply thin cake fertilizer water once a month. From September onward, switch to liquid fertilizer mainly based on potassium fertilizer, such as a 1% potassium sulfate solution or wood ash extract, to help the leaves stay bright red.

[Leaf Removal]

Most red maple cultivars are red during the new leaf stage, gradually turn green in summer, and then turn red again after frost. In order to make red maple show red leaves ahead of time around National Day, the method of leaf removal can be used to force reddening and compel new leaves to sprout.

The specific method is:

In mid-August, remove all the leaves on the plant together with the petioles. Place it in a sunny spot, apply manure 1-2 times, and water once a day to keep the potting soil moist, while also appropriately spraying water on the branches. After about half a month, the axillary buds will gradually sprout and produce small red leaves. In late September, the whole leaves will mature, and the whole tree will have red leaves, just in time to enjoy them during National Day.
