First: don't let the geranium flowerpot accumulate water in summer. It's better to match the soil medium with the one that can be dried as soon as possible, such as peat soil + perlite + a small amount of plant ash, and try not to use the soil medium with good water retention, such as Cuiyun beautiful soil.
Second: there is a saying that has been said many times: the first thing Geranium needs most in hot summer is ventilation, the second is ventilation, and the third is ventilation.
First of all, it's easy to ventilate the flower friends who have yard. Pay attention to half shade of geranium, and don't let the roots of Geranium be in the environment of water accumulation. Basically, it's safe. Except for summer, geranium is really a very good plant to keep, so the outdoor flower friends can not look down.
Secondly, Huayou, who lives in a building but has transparent rooms from north to south, put all the geraniums on the beiyangtai (the unsealed ones are the best) because of the good ventilation conditions to avoid exposure to the sun, control the water and fertilizer, and basically have no worries.
Finally, the most bitter situation for geranium is to live in a closed south balcony with poor ventilation. It's easy to die of black stem and completely hang up. So be sure to pay attention to ventilation!
1. Wooden basin (it can't guarantee 100% summer, but 90% is OK)
2. Drill more holes on the plastic basin to ventilate, so that the soil can dry quickly.
3. Use a small cane basket, but be careful where the water flows.
4. Other methods, for example, one is to draw lessons from Clematis' conduit root irrigation method, the other is to draw lessons from African cordiery's cotton strip water diversion method. In practice, it is summarized after autumn.
