Indoor cultivation and habits of Euonymus tomentosa

Small leaf yellow poplar likes warm, semi-overcast, humid climate, drought resistance, cold resistance, pruning resistance, is a shallow root tree species, slow growth, long life, is an excellent wood for bonsai production.

Populus tomentosa bonsai has dense branches and leaves and evergreen four seasons. It is not only a good indoor decorative plant, but also has a strong adsorption capacity to sulfur dioxide, chlorine, hydrogen sulfide, hydrogen fluoride and other toxic gases, and has the ability to absorb poisonous gas and purify the air. It is a veritable indoor "evergreen purifier", but if it is kept indoors for a long time, no sunlight will affect its normal growth, new branches are thin, and it is easy to breed diseases and insect pests.

Populus tomentosa can be dug and planted all the year round, but summer is the best, spring and autumn is the second, and winter is the worst. After excavation, the pile blank can be wrapped in plastic bags to moisturize the roots. To remove the descending main root when planting, it is best to seal all the wounds with commercial latex and cut off most of the leaves to prevent water loss and ensure survival. The billet can be raised in the open field or directly on the basin, but it must be cultivated for more than two years before it can be made.

The choice of basin can be Yixing purple sand basin or light glazed pottery basin. The shape and size of the basin can be determined according to the size and shape of the pile. In principle, the cliff type should be square or round thousand-cylinder basin, oblique dry type, curved dry type, jungle type, etc., and round, oval and rectangular basins should be used.

Potted soil small leaf yellow poplar likes fertile sandy loam, potted soil is better with fertile, loose, aerated and permeable sandy loam, and can also be mixed with slag 40%, rotten soil or vegetable garden soil 40%, and river sand 20%.

The best time for potting is between spring and summer. The excessively long and dense roots should be cut off when planting, and the roots can be modified to make the roots stretch naturally in the basin according to the needs of modeling. The depth of planting should not be too deep, after covering the soil with water, put it in a semi-shady place, keep the basin soil moist, spray water frequently to the leaf surface, and wait for about 30 days for the plant to grow, then it can be transferred to normal maintenance.

Modeling production should be based on the basic tree appearance of the plant, make measures according to the tree, let nature take its course, and carry out artistic modeling. Modeling techniques can be cut, can be tied, but climbing in summer and autumn is the best, when the branches are more flexible, easy to bend; pruning should be carried out in spring. It should be paid special attention to: although the germination power of Buxus microphylla is very strong, it is "no leaves will not be sent". Therefore, no matter it is styling or daily pruning, the method of "leaving leaves one by one, short cutting and forcing the bud" can be used for the branches that are not in place. And do not blindly pursue one step in place, do not leave the bitter pruning of branches and leaves, this often causes the branches and the whole plant not to germinate or even die.

The maintenance and management of small leaf boxwood likes to be wet and needs to be watered frequently to prevent the leaves from falling off due to water loss. The period from May to August is the peak growth period of Populus tomentosa, which can be combined with watering and applying thin rotten cake fertilizer for several times. Always pay attention to pruning overgrown branches, overlapping branches and extra branches that affect the shape of the tree. The fruit of Euonymus tomentosa should be picked in time so as not to consume nutrients. Generally speaking, small and medium-sized bonsai can be changed for 2 to 3 years and once every 5 years for small and medium-sized boxes. for plants with weak growth, the pot should be turned in time. Combined with changing the basin, cut off some of the over-long and dense old roots, replace the new culture soil and replant.

The main diseases and insect pests of Populus tomentosa are the larvae of shell insects and leaf rollers and soot disease. The control of leaf roll moth larvae and shell insects can be sprayed with 1500 times of dichlorvos. The key to the prevention and control of soot disease is to often spray water on the leaves and wash dust.
