The function of pruning watermelon is to prevent the growth of ineffective stems and vines, because these stems and 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 carried out in summer, because watermelon grows vigorously in summer, and the specific pruning time is from late June to early July, and the weather needs to be observed before pruning. In general, pruning can be done on sunny days.
Watermelon pruning method
Watermelon is generally pruned by three vines. When the main branch of watermelon has 8-9 true leaves, choose the main branch and two robust lateral branches, and prune all the other lateral branches, which can avoid the consumption of excess nutrients and is beneficial to the later 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 smooth. Pay attention to leave a 3-5 cm base in the trimmed part, so that the main branch will not be damaged when the wound heals. Scissors should be disinfected before use.
