What to do when mint wilts in hot weather? Master the first-aid methods while there is still time
Mint pest: whiteflies
If you notice the mint leaves at home feel sticky, and on closer look there are small white flying insects, then those are whiteflies!
Solutions:
1. Leaf-pulling method
Directly cut off all the leaves with whiteflies to destroy the whiteflies' nest. Do not feel reluctant, this is the most effective way to get rid of whiteflies.
2. Freezing method
Find a plastic bottle, fill it with water, leave it in the sun for a day, then put it in the refrigerator to freeze into icy water, pour it into a spray bottle and spray the front and back of the leaves. Be careful not to do this in the sun, and wait until the water on the leaves dries before taking them back into the sun.
Whiteflies are very afraid of cold, while mint is a plant tolerant of both cold and heat, so there is no need to worry that the mint will be damaged by freezing.
3. Homemade sticky insect traps
Insert some wooden sticks around the mint pot, wrap them with a loop of yellow tape to make homemade sticky traps, and use the whiteflies' attraction to yellow to eliminate them.
Mint pest: red spider mites
Turn over the back of the mint leaves and you will find a dense cluster of small red dots. Do not doubt it, those must be red spider mites.
Solutions:
1. Ventilate and remove leaves
Ventilate, observe the back of the mint leaves, and immediately remove any diseased leaves you find.
2. Homemade chili water
Cut some hot peppers, the spicy kind, add water about 30 times the amount of the peppers, boil for 30 minutes, put it in a bottle and spray it on the surface of the mint leaves. It is very effective against red spider mites.
Mint diseases
Rust
It usually occurs during continuous rainy days or excessive drought from May to July. It can be controlled with triadimefon emulsifiable concentrate solution.
Leaf spot
It usually occurs from May to October. Diseased leaves should be removed promptly, and at the early stage of the disease spray with a 500-fold dilution of 65% mancozeb wettable powder.
Black shank
Black shank usually occurs at the seedling stage, causing the stem of the mint to become soft and black, making the whole plant lodge and wilt. For control, spray with 70% chlorothalonil diluted with water during the period of disease.
Huahua reminds you: for sick mint, if you do not want to spray chemicals, just cut off all the sick leaves, place it in a windy and sunny spot, and let it slowly recover~
Curled edges and scorched leaves
Causes
The surface of mint leaves has a layer of fine hairs, so water easily collects on the leaves when watering, and prolonged soaking can cause the new shoots to die.
Solutions
In this case, appropriately increase ventilation, do not let it get directly rained on during cloudy and rainy days, and do not spray water on the leaves.
Daily care of mint
Temperature
The most suitable temperature for mint growth is between 20°C and 30°C. In summer, as long as the moisture is suitable, the higher the temperature, the better the mint at home grows.
Water
When watering in summer, you can check how moist the potting soil is. If the soil turns white, then water it quickly, and be sure to water thoroughly. If you have rice-washing water at home, save some to water the mint, and it will grow even better.
Soil
Sandy soil is best, and keep the soil loose and breathable at all times.
Even while the mint keeps growing, it should still be pruned and shaped, and then top-dressed around the base of the plant. A nitrogen fertilizer such as urea can be applied once a month.
The summer is hot
It is exactly the good season for growing mint
Everyone should quickly check their own mint at home,
and try to treat the problem according to its cause!
