Summer is a geranium nightmare. Let the geranium rot if you don't pay a little attention to it.

Shortly after the beginning of summer, it has been very hot this week, and I can see that all flower friends are worried about the summer problem of geraniums. I am also very nervous every summer. Although I have had a few years of summer experience, I still have to be careful. Let's talk about the problems that geraniums may encounter in the summer:

What are geraniums afraid of spending the summer?

1. High temperature

High temperature will affect the synthesis of chlorophyll in the new buds of Xiaotian, and the leaves that lack chlorophyll will appear yellow and white. My side of the summer, the lowest temperature of more than 28 degrees, the heat-resistant days of the new buds will be whitened. When the lowest temperature exceeds 30 degrees, white leaves will appear in most upright and hanging skies. Dahuatian and angels will cause the old leaves to turn yellow and dry up gradually because the water evaporates quickly.

two。 Damp and hot

In the south of the Yangtze River, there will be "Huangmei days" for a few weeks. Although there is no big sun, it is often overcast and rainy, but the temperature is not low, and the air humidity is very high. In such a season, if you don't clean up the dead leaves in the lower part of the world in time, you can see the dead leaves in the flowerpot begin to grow white hair (mildew) every other day. At this time, the content of all kinds of bacteria in the soil is very high, a little careless, the small day will be black. At the beginning of the black pole, it is often invisible to the naked eye. Xiaotian shows symptoms similar to lack of water. The leaves wilt and then wither and yellow. If you are not careful, it will often increase the amount of water, which will further worsen the condition of the black stem, until in the end, the blackened and rotten stem is completely broken.

3. Over-dry

Because they are worried about the black pole, many flower friends will adopt the way of water control to raise the small day in summer, but improper water control will make the roots lack of water, causing the old leaves to turn yellow and fall off gradually. For the upright days of large flowers and Lignification of the main stem, I will not control the water, but water it every day and water it full. (old pot, well-developed root system, soil all over the root system, so feel free to water boldly. They still flourish in summer. And blossom. ) the sky and angels are fed with the right amount for two days a day. There is no Lignification of the sub-adult plants on the careful watering, slowly along the flowerpot on a circle, the right amount. Try not to wet the green main stem.

Main cause of death

1. Black pole

The cancer of geranium is basically hopeless as soon as it is discovered. The cause is damp-heat.

two。 Debilitated to death due to inability to perform photosynthesis

If the new leaves cannot produce chlorophyll because of the high temperature, and the old leaves lose light because they are too dry, they will be weakened to death because there is no chlorophyll for photosynthesis.

3. Dry to death

The root system is damaged by excessive water control, and it is not easy to grow new roots in hot weather, and gradually die of thirst.

Flower friends who like geraniums comprehensively consider what measures to take to spend the summer according to their own conditions. I hope that after the cool autumn, we can see the beautiful flowers of the geraniums. I used to post some of the problems of soil and watering methods, but I am lazy to write about them here. )
