Why can't these flowers be rained on in summer? An analysis of the reasons

In summer, in some places, rain is very frequent! Recently, many gardening friends have left messages for Chengcheng, saying that their flowers, ever since being rained on, have developed all kinds of problems, and two pots even died. They asked Chengcheng what the reason was.
Chengcheng tells everyone:Rainwater itself does no harm to any plant. Especially for some plants that prefer acidic soil, such as camellias, gardenias, jasmine, and so on, when it rains, letting them get rained on, or giving them a little rainwater, is definitely all benefit and no harm!
But there are some plants,such as snake plants, ball cacti, prickly pear cacti, and so on. They have a certain drought resistance themselves, and normally need very little water. If they are placed outdoors and get rained on, it will cause excess water, and once there is excess water, in summer, this high-temperature, high-humidity season, it is very easy to cause their root systems to rot!
And the succulents we grow,must absolutely not be rained on in summer either, because after being rained on, the potting soil cannot dry out for a long time. Once the weather clears and the temperature rises, the damp soil will become abnormally hot and humid. To say it is like a little steamer is really no exaggeration at all. If you are not careful, it will suffocate the succulent's roots to death!
In addition,for some plants that are blooming, we had best not let them get rained on either, because although rain does not affect their growth, since they are blooming, once the rain falls, the flowers immediately drop!
In short, rainwater itself does no harm to any flower. You can use it to water flowers, but be sure not to let your beloved flowers get rained on casually!
