The function of pruning watermelon is to prevent the growth of ineffective vines, because these vines will consume nutrients and affect the better growth of plants, so pruning can promote the growth of plants with more nutrients. Watermelon pruning is best done in summer, because watermelons grow vigorously in summer. The suitable pruning time is from late June to early July, and the weather should be observed before pruning. Generally speaking, it can be trimmed when the weather is good.
Watermelon pruning method
Watermelon is generally pruned by three-vine pruning method. When the main branch of watermelon has 8-9 real leaves, choose the main branch and two robust side branches, and cut off all the other side branches. This can avoid the consumption of excess nutrients and is beneficial to the flowering and fruiting of watermelon plants.
Matters needing attention in watermelon pruning
When pruning watermelons, use sharp scissors, so that the wounds of watermelon plants can be relatively small and flat. Pay attention to trim the base of the site 3-5cm, so that the main branch will not be damaged when the wound heals. Scissors should be disinfected before use.
