I usually buy flower seedlings online for more than two years, usually in late autumn. At this time, everything began to enter a dormant period. At this time, planting Camptotheca acuminata can make it have enough dormancy period, and with abundant snowfall in winter, it can better meet the water and nutrition needs of Camptotheca acuminata in spring.

My practice is to cut off most of the Camptotheca acuminata trees I bought and bury the rest in the soil together with the roots. On the one hand, it can better keep out the cold, on the other hand, it can save and absorb more water, laying a good foundation for rooting and sprouting in the coming year. The survival rate of Camptotheca acuminata planted by this method is over 90%.

Of course, if you plant Camptotheca acuminata at home, you can also choose cutting or layering to make it take root and sprout. Cutting is a bit complicated. You need to choose strong branches as cutting mother strips, cut off 10- 15 cm branches and soak them in a container filled with rooting water, and the roots will come back in a week or so. I think this method has a low survival rate.

The layering method has high survival rate and simple operation. You just need to bury the branches you choose with soil. If they are in the sky, you can put the soil in a plastic bottle and then bury the branches in the plastic bottle. Generally, it will take root in 1-2 weeks, and after taking root, it can be directly planted by cutting.

2, water and fertilizer soil

Camptotheca acuminata likes neutral soil very much, so it must ensure good drainage performance. Sandy soil with good ventilation and drainage performance is suitable. Camptotheca acuminata doesn't like much water (waterlogging) and is drought-tolerant, so you can choose to water it regularly. Generally, I water it about three times a month, but it is easy to evaporate in summer, so the number of times of adding water can be increased appropriately. Camptotheca acuminata doesn't like too much fertilizer either. Generally, if you want to feed Camptotheca acuminata, you can meet its own needs.

3. Lighting temperature

Camptotheca acuminata likes light, usually 5-6 hours is the best. At the same time, it also likes proper shading, especially in summer. If it exceeds 30 degrees, it is necessary to shade and cool down. Courtyard farming should choose a ventilated place. In winter, we usually choose to cover the surface of camphor tree with straw to increase its temperature. If it is below-10 degrees, freezing injury may occur, so pay attention to keep warm and keep out the cold.

4. Pruning and coring

Prune camphor trees lightly. The first pruning is in early spring, when everything is revived, which is also an important pruning that determines how much camphor trees bloom. At this time, pruning should keep the long and strong main branches, remove the old, weak, sick and residual branches, and ensure that nutrients can be fully supplied to the main branches. The second pruning should be carried out after flowering, so that the whole plant can have a good growth form, and pruning should be carried out according to the growth of the plant and its desired development direction.

5. Diseases and pests

Aphids and scale insects are favorite pests of Camptotheca acuminata, which are common in hot and humid summer. The best way to deal with these two kinds of insects is to use pesticides, commonly used dimethoate, dilute it according to the instructions and spray it directly on the surface of Camptotheca acuminata, which can be reduced or even disappeared on the same day.

The common diseases of Camptotheca acuminata are leaf spot and powdery mildew, both of which are caused by bacterial infection, so the first thing we should do is to remove the diseased leaves and destroy them, and then use drugs. I usually choose carbendazim, but there are other fungicides that can be diluted according to the instructions and sprayed on the surface of Camptotheca acuminata.
