If you grow flowers on a rainy day, the leaves will get moldy and spotty. If you don't take care of them, they will all die!

Wet flower pots

It is easy for moisture to accumulate in flower pots on rainy days for two reasons: the humidity is high on rainy days and evaporation is low. If you still water the flowers normally, the flowers can only absorb a small part of it, and the rest cannot evaporate and accumulate in the pot; flowers left outside in the rain will be wet for one or two days, and the rain water far exceeds what the flowers need.

Solution 1: Water less on rainy days and use holes in the flowerpot

This method is mainly to prevent and avoid water accumulation in the pot. Be sure to water less on rainy days, especially for flowers that are afraid of waterlogging, such as money trees, Clivia, Kalanchoe, etc. The humidity in the air is already sufficient. If you leave it outside in the rain, the bottom of the pot must have holes, and the holes in a large flowerpot should be larger.

Solution 2: Place bricks under the basin to isolate the water source

Flowers that are left outside in the rain should not be placed directly on the ground. First, the water in the pot will not easily seep out. Second, contact with the wet ground is equivalent to soaking in water, which can easily lead to bacterial infection and root rot. We can put two bricks under the pot to expose the small holes at the bottom of the pot, so you don’t have to worry about being exposed to the rain for a whole day!

Solution 3: Turn on the fan to ventilate and find a way to dry it

If your flower pots are wet for 2 or 3 days, stop watering them immediately and put them in a ventilated place. If necessary, blow a fan on the flowers to speed up evaporation. If the situation is serious, take out the flowers with the soil, let them air dry, and put them back in the pots when they are almost dry.

Various flower diseases

After a rain, flowers are prone to disease, which mainly manifests itself on the leaves. You must be careful of the following situations!

Black spot disease: During the rainy season in summer every year, black spots will appear on the leaves of the flowers after being rained on. The spots spread quickly and the flowers will be left with nothing in a few days.

Solution: Sprinkle wood shavings on the surface of the basin, spray pesticide

Put some wood shavings, coal slag, bamboo charcoal, etc. on the surface of the pot to isolate the bacteria in the soil. When the rain stops, spray some carbendazim on the leaves. Then, away from the rain, place them on a ventilated balcony indoors to see the effect.

Anthracnose: It is caused by insufficient sunlight, high humidity and insufficient ventilation on rainy days. It is especially common in foliage flowers such as orchids, green ivy, money trees and monsteras. There are necrotic parts on the leaves that look like yellow water stains.

Solution: Clean up the rotten leaves and apply fungicide in time

The yellow and rotten leaves in the flower pots should be cleaned up in time. Some fungicides can be added to the soil and some coal slag can be added to the soil surface. When watering, be sure not to spray the leaves as this can easily spread the disease. Just water directly into the soil. Cut off the diseased leaves directly and apply some gentian violet or Daknin to the wound for sterilization and disinfection.

Powdery mildew: The air humidity is high on rainy days, and mushrooms grow in the flower pots of many flower lovers. White silk fibers appear on the flowers and leaves. Roses, geraniums, chrysanthemums, gloxinia, and clematis are all prone to powdery mildew.

Solution: Apply sulfur and ventilate frequently

Rub the sulfur soap at home into powder on cement, then sprinkle the sulfur powder on the diseased areas of the leaves. Be sure to keep it ventilated, whether on the balcony or windowsill, or with a fan, ventilation is the key. If the leaves are seriously infested, pick them off directly and apply some carbendazim, daktarin or gentian violet to kill bacteria.

Wilt disease: Some flowers will wither immediately after it rains, and there is no way to stop it, such as Clematis. It is so expensive, but it dies before even a rain. It is really painful. I hope it is not too late for Huahua to say it today.

Solution: Choose the right variety and spread some wood ash when it rains

Among Clematis, the entire series has the least amount of immediate withering, followed by the F series, and the 2 series has the most immediate withering. Flower lovers should buy according to their means. To avoid sudden withering, you can sprinkle a handful of wood ash on the soil surface of the clematis when it rains to kill bacteria and reduce moisture.

Rain attracts insects

There are many insects in the summer, and it is even more common when growing flowers. Especially when it rains, all the little insects come out. How do you deal with them?

Small flying insects: Some small flying insects surround the flower pots all day long, which is very annoying. In fact, it is because the soil in the pots is too wet. The white insects you find in the soil are their young.

Solution: Ventilation is the root cause, mosquito coils kill insects

If you want to completely eliminate small flying insects, you must maintain a ventilated flower-growing environment and do not water too much, otherwise everything will be in vain. If there is no way to cure the problem, you can also light mosquito coils around the flowers, or break the mosquito coils into pieces and stick them into the soil along the edge of the pot. The small flying insects will immediately stun.

Scale insects: Some flowers (especially succulents) are prone to scale insects in summer. The insects cling tightly to the flowers, and they grow more and more. Killing them one by one is not a solution. What can you do?

Solution: Alcohol insecticide

Use a cotton swab to dip in the medical alcohol (30-50% concentration) that you always have at home and wipe the leaves, both sides. If you find it troublesome, you can use a small spray bottle to spray it. Be careful not to spray too hard. The effect is more obvious around 6-8 pm.
