Rose disease and insect pests cause death

Summer is the peak season for rose diseases and pests. If the plants are always airtight, or water gets on the leaves when watering, various diseases and pests will occur. Leaf spot disease, red spider mites, powdery mildew all come knocking on your door, it's simply impossible to guard against them!

Death caused by exposure to the sun

Causes:

Although summer is the peak growth period of green radish, you still need to pay attention to shade in hot weather. If the green radish is exposed to the scorching sun, it will easily die.

Solution:

1. Check the condition of the green radish. If you find that many leaves are sunburned, cut them off immediately, because the sunburned leaves cannot recover at all. Cutting them off can also reduce nutrient consumption.

2. Place the green radish in a cool and ventilated place indoors, water it thoroughly once, and then take care of it for a period of time. The sunburned green radish will recover quickly.

How to prevent green radish from sunburn:
