 edge dry volume, high temperature sunburn will damage the bark, more cold resistant, north of the Yellow River, it is appropriate to pot, winter is appropriate. But spring and autumn can also grow in full light. The soil

grafting

It is advisable to use 2 to 4 years old maple seedlings as rootstock, cutting should be done in March to April, the height of the rootstock can be determined according to need; The grafting is carried out in the plum rain season in May and June, and cut off after the fall leaves, this method is only used for a few precious varieties. Bud grafting is the most common application, and the best time is from late May to late June and from late August to late September after autumn. Early summer is the most prosperous period of branch growth. The full buds on the sunny short branches of red maple with 1 cm long petiole are used as grafting buds. The temperature after grafting is gradually higher, although the plastic band is tied after grafting, the bud and petiole are still exposed, and the red maple cortex is thin, and the bud is small, so it should be regularly sprayed and moisturized after pressing to improve the survival rate. The method of budding after autumn is basically the same. After 1 week, if the petiole is touched and falls, it means that it has survived, otherwise it should be repaired.

cutting

This method is especially useful when making small bonsai or potted plants. Cuttings are generally carried out during the Meiyu period from June to July. Select the strong branches about 20 cm in length as cuttings, quickly dip 1000 mg/kg naphthalene acetic acid powder, and plug into the medium of vermiculite or perlite and half of the mud. Pay attention to shade in the future; Spray water to moisturize, about 1 month later can gradually take root. If there are all light spray conditions, the selection of 2-year shoots can also take root, and the survival rate is high. After transplantation, shade should be carried out, sunlight can be gradually accepted after half a month, and water and fertilizer management should be strengthened.

Cultivation technique

Most varieties of red maple are red in the new leaf stage, gradually change to green in summer, and then turn to red after frost. In order to make red maple leaves before and after National Day, the method of leaf picking 

can be used to promote red and force new leaves to sprout. The method is to remove all the leaves and petioles from the plant in mid-August. Place in a sunny place, follow the manure 1-2 times, and water once a day, 

keep the basin soil moist, and spray water on the branches as appropriate. After about half a month, the axillary buds will sprout one after another, and small red leaves will emerge. In late September, the whole leaves 

will mature, and the whole tree will have red leaves, which will be appreciated during the National Day.
