Goji berry winter pruning methods and technical key points

Medicinal Herb Cultivation 0 views
After a year of growth, the goji berry tree has many branches and a messy crown, and while new fruiting branches are forming, some fruiting branches have already begun to age. Therefore, goji berries need to be pruned in winter, otherwise the yield and quality of the following year will be affected. Through pruning, the old is removed and replaced with the new, retaining the old-eye branches and seven-inch branches with strong fruiting capacity, and cutting off non-productive branches, which can lay a good foundation for the old-eye branches to bear fruit and for new fruiting branches to grow the next year. Top pruning To make management convenient, the tree height needs to be controlled by top pruning.

Top pruning To make management convenient, the tree height needs to be controlled by top pruning. Generally, the tree height should be controlled at 1-8 m. Where there is space in the upper part of the crown, the water sprouts should be cut back, retaining branch stubs of about 20 cm to encourage branching and fill in the crown. Water-sprout branches with no value for retention should be cut off from the base.

Bottom cutting To facilitate soil management in the goji berry orchard and prevent the fruit on drooping branches from rotting, branches at the base of the crown that touch the ground should be cut back at a height of 30 cm from the ground.

Clearing the interior Thin, weak branches inside the crown should be removed, and densely crowded branches should be appropriately thinned to maintain good ventilation and light penetration, which is beneficial for fruit growth and development.

Perimeter trimming This refers to pruning the fruiting branch layer of the crown. It mainly involves retaining good fruiting branches and cutting off old branches, thorny branches, diseased and pest-damaged branches, wind-broken branches, crossing branches, overlapping branches and densely crowded branches in the fruiting branch layer. When pruning, the retention or removal of old branches should be decided according to the number of new fruiting branches. If there are many new branches, the old branches can be cut back to a vigorous branching point.

Winter pruning should be light rather than heavy, and not too much should be cut back. This is because the buds at 16-50 cm from the tips of the branches are the earliest to bear fruit the following year; if fruiting branches are cut back too much, it will directly affect the yield of spring fruit the next year. To avoid missing any cuts, pruning should be done carefully from top to bottom, going around the crown in one direction.
