Common problems in summer plum maintenance

Be careful of wind

Wintersweet is afraid of wind, so choose a sheltered place for outdoor cultivation. If wind protection is not done properly, the blades will rust due to friction with each other. If exposed to wind during the flowering period, the flower buds will not open easily and the petals will not stretch out.

Timely pruning

Wintersweet has a strong ability to branch out, and timely pruning is beneficial to promote the sprouting of more branches and more flowering. Pruning is suitable from the time when flowers fade to the time when leaves sprout, usually from March to June, and stop after July. Cut off diseased and insect-infested branches, dead branches, crossed branches, and overcrowded branches. Keep 2-3 pairs of buds at the base of annual branches and cut off the upper branches to promote branching. Pinch the tops of new branches every time they grow two or three pairs of leaves.

Pest Control

The main pests are scale insects and aphids. Scale insects are generally found in dark and humid planting areas, especially in the summer when rainfall is concentrated. The high temperature and humidity make it easy for summer sweetness to be harmed by scale insects, and timely artificial prevention and control is required. At the turn of spring and summer, the tender buds of wintersweets are easily harmed by aphids, which can be killed by spraying with 3000 times diluted 50% anthelmintic.

Disease control

The main diseases that occur are black spot and anthracnose, which occur most frequently in high temperature seasons. For black spot disease, you can spray 500 times diluted 65% Zineb or 0.3 Baume-stone mixture. Anthracnose can be prevented and controlled by spraying 800 times diluted thiophanate.
