What is the reason for the inward curling of the leaves of Endless Summer? What should I do if the leaves of Endless Summer are infested with insects?

Endless Summer is a type of hydrangea, with beautiful flowers and large size, which is very ornamental. Sometimes the leaves of Endless Summer will curl inwards, so what is the reason? What should I do if the leaves are infested with insects?

What happened to the inward-curling edges of the Endless Summer leaves?

1. Watering too much or too little. The weather is dry and the temperature is relatively high now. If you put the Endless Summer on the terrace, you need to water it at least once a day, otherwise the leaves will turn inward and wilt. At the same time, there should be no accumulation of water if you keep the Endless Summer indoors.

2. Regarding the issue of sunlight, Endless Summer only needs proper shade in this season, but it cannot be completely without sunlight, otherwise the leaves will bend inward or droop. It should also not be exposed to the sun frequently. Ventilation is also very important.

3. Another problem is that the soil is compacted and water cannot be poured thoroughly, which can easily cause the leaves to grow unhealthily.

4. Iron deficiency in the potting soil may also cause this situation. You can water it with 0.2% ferrous sulfate, or spray potassium dihydrogen phosphate, or edible vinegar water every half a month. This will make the leaves stretch out, become lush and green.

What to do if the leaves of Endless Summer are infested with insects

One is thrips. You can buy a sticky insect basket and place it next to the plant to kill most of the pests. You can also buy some thrips-killing drugs, which are available in general pesticide stores. Spray once or twice.

The second type is the adult of the ground maggot. This one still has eggs in the soil, and now it has broken out on a large scale. First check if there are larvae in the soil. If there are, then you need to irrigate the soil with medicine. To remove the adults, you can use sticky yellow insect boards or medication.

The third possibility is leaf miners. Check the leaves of the hydrangea to see if there are stripes similar to those where insects crawled. These stripes are inside the leaves, and if you look closely, you can see the insect bodies. In this case, you can cut off the affected leaves or use drugs to kill leaf miners.

How to maintain Endless Summer

Endless Summer likes semi-shade or sparse light environment under the forest. It cannot tolerate strong direct sunlight. In spring, it can be properly exposed to sufficient light. After entering summer, it is necessary to avoid direct sunlight during the noon period. It is best to shade it from the side. In addition, it is a short-day flowering plant, but it cannot bloom without sunlight for a long time. The daily light time should be controlled at 8-9 hours.

The color of the Endless Summer hydrangea will change depending on the pH of the soil, turning blue in acid and pink in alkaline. If you want to bloom pure blue flowers, you need to start improving the soil pH before the buds grow. You can bury hydrangea blueing agent in the soil, and apply some ferrous sulfate or white vinegar every 2 weeks or so after the buds are produced.

Endless Summer should be cut off in time after flowering. If the environment is suitable, it can continue to bloom in summer and last until late autumn. When the temperature exceeds 30 degrees in summer, it should be shaded to cool it down. Put it in a cool place at noon to cool it down, and spray more water around it to increase air humidity and lower the temperature. It is best not to fertilize in summer. Pay attention to watering when the soil is dry and wet, and do not let the pot soil be too wet for a long time.
