These flowers must never be left in the rain; move them indoors as soon as possible to keep them from withering and dying.
Clivia must not be left in the rain; one rain and its core rots!
Although Clivia (Clivia miniata) is fine with an occasional rain shower, once a stretch of nonstop overcast and rainy days hits, you must make sure no water collects in the leaf core, otherwise the core will easily rot.
Solutions:
1. If your Clivia gets rained on, quickly dry the water in the leaf core with a paper towel, and at the same time move it to a ventilated spot, pour out the standing water in the pot, or let the excess moisture evaporate as quickly as possible.
2. If the core rot is severe, and even the leaves have rotted away, then the only option is to behead the Clivia, cutting off all the rotten leaves and leaf core, and let it push out new shoots again.
Gloxinia must not be left in the rain; one rain and its leaves rot!
Gloxinia (Sinningia speciosa) leaves are covered in fine fuzz, and once they accidentally get wet and aren't dealt with promptly, the leaves will rot, and over time the whole plant will rot along with them!
Solutions:
1. If the Gloxinia leaves accidentally get rained on, immediately place it somewhere with good ventilation and let the water on the leaves evaporate. When watering normally, try not to let water touch the leaves; if it does accidentally get on them, just wipe it off promptly.
2. If the leaf rot is severe, find a knife and cut off the rotten leaves, keep the healthy leaves, and stick them in loose, breathable soil to root; before long they'll take root and grow into new Gloxinias!
Cactus must not be left in the rain; one rain and the ball rots!
Lately I've really fallen in love with cactus; not only is it easy to grow, but each bloom can produce dozens of flowers! Moreover, cactus is fairly drought-tolerant, but once too much rain causes standing water in the pot, and then the temperature rises after the rain, the cactus ends up steaming like in a sauna, and in severe cases the whole ball will rot away!
How to solve it?
1. If the cactus rots from being rained on, find a sterilized knife, cut off the entire rotten ball, then smear a little wood ash or carbendazim on the wound, and leave it in a cool place for the wound to dry.
2. When watering cactus normally, it's best to water along the edge of the pot, straight into the soil; don't water from the top of the cactus, otherwise the ball will easily rot. If it's grown outdoors, getting rained on is fine, but after the rain it must not be in direct sun; just move it to a cool, shady spot.
Fuzzy succulents must not be left in the rain; one rain and they get black rot!
Many succulents have fuzz on their leaves, so when watering normally, be careful not to get it on the leaves. If they accidentally get rained on, and then the temperature rises after the rain, your succulents immediately turn into boiled meat and will surely die!
How to solve it?
1. If your succulents get rained on, immediately move them to a cool, ventilated spot, and absolutely do not put them back in blazing sun, otherwise they'll turn to mush and black rot even more easily. You can use a small fan to blow on them so the moisture evaporates as quickly as possible.
2. If black rot appears on the succulents, immediately cut off the black-rotted parts, then soak them in carbendazim for a while, and repot them. If the roots have already rotted, just put them in soil to re-root.
