How to improve the survival rate of Magnolia grandiflora transplantation

Soil ball size

The size of the soil ball is the key to the success of Magnolia grandiflora transplanting.

In East China, the diameter of the soil ball is generally 8 to 10 times the tree's breast diameter. The soil ball should be dug into a gyroscope shape rather than a plate or cone shape, and should be tied tightly with straw rope to prevent it from loosening during transportation.

Transplantation Season

It is best to transplant large Magnolia trees in early spring, but the best time is the rainy season. When transplanting, it is best to choose a cloudy or overcast day.

Transplanting can be done about half a month after the Spring Festival. When the temperature rises in late spring, the roots begin to sprout and grow. In addition, there is heavy rainfall and high air humidity during the rainy season, so the survival rate of transplanted Magnolia grandiflora is very high at this time.

Water requirements

Digging and planting must be done quickly and in a timely manner to avoid excessive water loss that may affect survival. After transplanting, the first rooting watering should be timely, and the watering should be sufficient and thorough. If there is too much rainfall after transplanting, drainage ditches need to be dug to prevent water accumulation at the roots, which will cause the magnolia to rot and die.

If the weather is dry, you can spray the tree crown or spray from above.

Pruning requirements

By pruning and removing leaves, water evaporation can be reduced and the water supply pressure on injured roots can be relieved.

It is advisable to pick off only 1/3 of the leaves on the branches, otherwise it will reduce the transpiration pull and make it difficult for the roots to absorb water.

Other Tips

During the transplanting process of Magnolia grandiflora, in order to promote the recovery of the root system, you can use the high-efficiency rooting agent "Quick Rooting".

After planting, supporting wood should be installed to fix the tree trunk to prevent shaking and damage to the root system. A tripod made of 3 to 4 meters long bamboo or other materials can be used for fixing.
