A Detailed Guide to Hawthorn Tree Transplanting Techniques and Precautions

In fact, in landscaping and garden construction nowadays, large-tree transplanting and tending management are mostly used, in the hope of achieving rapid greening and beautification effects in the garden. So the editor of Jiantu Liu Wang is going to talk about the transplanting techniques for hawthorn trees. Let's take a look together~

1. Transplant at the right time

Transplant after leaf fall in autumn and winter up to before the soil freezes, and before bud break in spring. However, to avoid the adverse effects of occasionally encountering relatively severe cold waves and low temperatures after transplanting, it is better to wait until the weather forecast shows no particularly low temperatures before transplanting after leaf fall in autumn and winter or before bud break in spring.

2. Rational root balling

1. Hawthorn is a shallow-rooted tree species, with an undeveloped taproot; lateral roots are mostly distributed within 50cm, with the greatest distribution in the 20-40cm soil layer. However, in deeply plowed loam or sandy loam, large hawthorn trees can reach a depth of 1.2-1.5m, and the horizontal distribution of roots can reach more than 15m. Therefore, transplanting large hawthorn trees usually requires advance preparation

2. In the spring or autumn 1-2 years before transplanting, with the trunk as the center and 2.5-3 times the trunk diameter as the radius, draw a circle, and outside the circle dig a trench 30-40cm wide (its depth depends on root distribution, generally 50-80cm), cut the roots flush with the inner wall, keep the large roots but girdle and peel the root bark, then fill level with live soil (preferably sandy loam or loam), tread firmly in layers, water regularly, and within 1-2 months many fibrous roots will grow in the trench. Root balling should generally be carried out in two stages, so as to avoid affecting the tree's life or causing death due to cutting all roots at once.

3. Usually in the first spring, choose the southeast two sides of the tree to dig and cut the roots, and in autumn use the same method to dig the other two sides. For large-tree transplanting, the protective original soil around the roots should be retained as much as possible, with a soil ball. In winter the aboveground part has already shed its leaves and water loss is low, so depending on the tree's shape and transport capacity, retain as many branches and trunks as possible, to facilitate faster restoration of the landscape after transplanting. But after all, a relatively large part of the underground portion has been cut away, so the aboveground part should also be pruned appropriately to achieve a balance of water and nutrients. Especially for large trees that are sprouting, if the transplanting period is the flowering period, improper pruning will overload the root system and even cause damage. In addition, to prevent wound infection and reduce water loss, larger wounds on roots and trunks should be sealed with latex, and larger wounds on branches and trunks should be bound with film. Build up a soil platform around it, fill in loose soil, and raise the planting hole to prevent water accumulation.

3. Strengthen tending management during the survival period of large trees

The first year after planting a large hawthorn tree is the key period for whether it can survive. During this period, tending management should be carried out promptly to ensure a relatively high survival rate for newly planted large hawthorn trees.

1. Straightening and mounding soil

If the tree disk sinks overall or locally, soil should be added promptly to fill it level, to prevent water accumulation and root rot after rain; if the soil in the tree disk is piled too high, it should be shoveled and raked level, to prevent the roots from being too deep and affecting root development. For leaning trees, measures should be taken to straighten them.

2. Water management

Transplanted trees are very sensitive to the amount of water due to root damage and environmental changes. Therefore, water management for newly planted trees is an important part of tending management during the survival period. In dry seasons, attention should be paid to irrigation, and it is best to ensure that the soil moisture content reaches 60% of maximum water-holding capacity. Under normal circumstances, in the first year after transplanting, watering should be done 5-6 times, and especially during high temperatures and drought, more attention should be paid to drought resistance. In hot and dry seasons, when leaves show mild wilting symptoms, a sprayer or spray gun can be used to spray water directly onto the crown or the upper part of the crown. Spraying can be done from 10 a.m. to 4 p.m., once every 1-2h, and if necessary, shade nets should also be set up to prevent excessively strong sunlight.

In addition, attention should also be paid to loosening the soil and weeding, rational fertilization, and replanting. That's all for today's hawthorn tree transplanting techniques, and we'll see you next time.
