What to do if the roots of crabapple are burned by fertilizer? How to prune

1. What to do if the roots are burned

If the roots of the crabapple are burned due to too much fertilizer or too high a concentration during maintenance, it is best to replace the potting soil. When the roots of the plant are burned, it is necessary to remove the pot immediately and take the plant out first. Then check the condition of its root system. If there is any rot, the rotten roots should be cut off first. Pour out the old soil from previous cultivation and replace it with new soil. Finally, disinfect the plants and plant them.

In addition, if yellow leaves appear due to root burn, the yellow leaves need to be cut off. If they are not cut off, the ornamental value will be reduced.

2. How to prune

1. When pruning crabapples in spring, you should cut off the thin, dry and cross-growing branches on the plant, which will be conducive to the growth of new buds. If there are poorly growing branches, they should be cut off from the base. In winter, plastic surgery can be performed according to specific circumstances.

2. In order to make it bloom better, it needs to be pruned before flowering, and the buds on the flowers should be thinned out. After flowering, the withered flowers should be cut off as soon as possible, and the flowering branches should also be pruned back. Pruning after flowering can help it survive the winter and reduce nutrient disinfection.
