It's too hot
With the scorching summer heat, mint plants in the house frequently show signs of burnt leaves and withered buds. Is it due to improper care or pests and diseases? As a robust aromatic plant, mint should thrive, but high temperatures and humidity often put it in a state of survival crisis. This article systematically analyzes common issues and solutions to help you become an expert in mint care.
War on Mint Pests
Dealing with Whitefly Infestation
When leaves exhibit sticky secretions accompanied by white flying insects, it indicates a whitefly infection. It is recommended to use a three-level treatment method: immediately remove the affected leaves upon initial discovery; for moderate infections, use the frozen water mist method (freeze water in a plastic bottle and spray avoiding strong sunlight); severe pest infestations require the use of yellow sticky traps, setting homemade sticky boards around the pot to exploit their phototaxis.

Dealing with Three Typical Diseases
• Rust: Common in the plum rain season, use a 15% triazole emulsion 1500 times solution for prevention and treatment.• Leaf spot disease: Likely to appear in the transition period between summer and autumn, a 65% zinc omadine 500 times solution is effective.• Black leg disease: A killer for seedlings, use a 70% chlorothalonil 800 times solution for root irrigation. Environmentalists can choose physical therapy: thoroughly prune diseased plants, enhance sunlight and ventilation, and apply wood ash.

Causes and Countermeasures for curled and Burnt Leaves
Water accumulation on the pubescent leaves is the main cause of burnt leaves. It is recommended to water from the bottom using the bottom watering method to avoid leaving water droplets on the leaves. Adjust immediately when burnt leaves appear: 1. Use a尖嘴壶 (spouted pot) to water along the pot edge. 2. Set up an air circulation fan to enhance ventilation. 3. Build a transparent rain shelter during the rainy season.
A Scientific Mint Care System
Four-dimensional Care Principles
• Temperature control: Maintain a growth golden range of 20-30°C, and shade cooling is required when it exceeds 35°C.• Smart watering: Use the "three-look watering method" - look at the soil color (water when it turns white), leaf condition (wilted as a warning), and weather (control water during rainy days).• Soil optimization: Loosen the soil once a month and mix in perlite to improve aeration.• Nutrient management: Alternate the use of rice washing water (diluted 1:20) and urea solution (once a month) during the growing season.
By systematic diagnosis and precise intervention, 90% of mint health issues can be resolved. The key is to establish a care concept of "prevention first, treatment second," regularly check the back of leaves, and control the growth environment. As long as you master these core techniques, your mint will surely survive the summer heat, continuously emitting a refreshing aroma.
