How much does a camphor tree and a ginkgo tree cost each, and are they suitable for planting in the north?

The camphor tree (Cinnamomum camphora) is an excellent landscaping tree, street tree and shade tree. The whole plant has a camphor aroma, and camphor and camphor oil can be extracted from it. Its wood is of superior quality and is a good material for making furniture. It is resistant to harmful gases such as chlorine, sulfur dioxide, ozone and fluorine gas, can repel mosquitoes and flies, and can withstand short-term flooding. The fruit of the ginkgo tree is commonly known as white fruit, hence the ginkgo is also called the white fruit tree. It grows relatively slowly and has an extremely long lifespan. Under natural conditions, it takes more than 20 years from planting to bearing ginkgo fruit, and only after 40 years can it bear fruit in large quantities. Therefore, some people also call it the “grandfather-grandson tree”, with the meaning of “the grandfather plants it and the grandson gets to eat”. It is the longevity star among trees and has ornamental, economic and medicinal value. Since they have so many benefits, let us take a look at how much each of these two trees costs, and whether they are suitable for planting in the north!

I. How much does a camphor tree cost each?

For camphor trees with a diameter of 6-7-8-9-10-12-15-18 (cm), the corresponding camphor prices are 45-65-95-130-170-270-580-1100 (yuan).

Because there are many factors affecting the price of nursery stock, the above prices are for everyone's reference only.

II. Are camphor trees suitable for planting in the north?

Camphor trees are actually not suitable for planting in the north. If you must plant them, then you need to be even more meticulous. The camphor tree has a graceful form, its branches and leaves can give off a fragrance, and it stays green all year round. It is an excellent street tree and shade tree and has relatively high economic value. Camphor trees like a warm and humid climate and fertile, deep acidic or neutral sandy soil, while the dry, windy climate and alkaline soil environment of the northern regions are not suitable for camphor growth. Below are the key points for planting in the north:

(1) Selection of nursery stock

The survival rate and planting effect of plants depend to a large extent on their own physiological characteristics, so transplanting camphor trees out of season should start from the following three aspects:

1. Choose nearby, that is, select seedlings in areas as close as possible to the transplanting site, so as to reduce the problems caused by long-distance transport, such as air-drying and dehydration of the large tree's trunk and roots and the breaking of the soil ball.

2. Make the soil ball as large as possible. If planting out of season, the camphor dug out from the nursery should have a larger soil ball than under normal conditions. In this way, the root system is relatively complete, and the transplanting survival rate is relatively higher. If it is a bare-root seedling, it should carry as much protecting soil around the roots as possible, and the retained roots should be long, with the more fine roots the better.

3. Use acclimatized seedlings and heeling-in seedlings. Seedlings that have been transplanted and acclimatized have basically adapted to the climate and environment of the north, and therefore have an extremely high survival rate; seedlings that have been heeled in for a period of time begin to sprout new roots at the root collar, are vigorous and thus have strong vitality and are easy to survive.

(2) Reasonable pruning

1. Bare-root seedlings: Before planting, cut off broken roots, dead roots and rotten roots, and also cut off 1/3 to 1/2 of all branches and leaves of the crown to reduce transpiration of the plant.

2. Seedlings with a soil ball: Root pruning is not needed; simply cut off 1/3 to 1/2 of the crown together with branches and leaves while maintaining the basic tree shape.

(3) Scientific planting

1. Timely planting: Camphor seedlings that have been pruned should be planted immediately. If the transport distance is relatively long, use wet grass and transpiration inhibitors to keep them moist.

2. Requirements for the planting hole: The hole should be large enough, and at the same time the inside of the hole should be kept clean. The bottom of the hole should be lined with soil from the original digging site or fine soil, and soil should be filled in multiple times up to the top of the hole, and a berm should be piled up around the seedling.

3. Scientific watering: After the plant is planted, water it immediately, and at the same time stir the soil around the tree hole so that the soil is packed firmly in the hole. In order to improve the survival rate of the tree after planting, agents such as rooting powder and large-tree transplant survival liquid can be added to the water to increase the activity of root hair cells and stimulate new root growth.

(4) Maintenance and management after transplanting

The maintenance work after transplanting camphor trees is also quite important. If camphor is transplanted in summer, spray clean water frequently on the ground and on the leaf surfaces of the camphor tree to increase air humidity and reduce transpiration of the plant. For ordinary watering, adhere to the principle of “do not water if not dry, and when watering, water thoroughly”. At the same time, to prevent excessive scorching, use shade netting to shade newly transplanted large camphor trees and avoid direct strong light.
