It's hot outside and the warm weather is set to stay. While it is a wonderful time to enjoy the garden, the hot weather also stresses sensitive plants. Here are some ways to keep your garden healthy in the heatwave.
Increase the frequency and duration of watering. Water your plants early in the morning or late in the evening to minimize evaporation. Focus on the root zones of the plants, as wetting the foliage can lead to scorching. Consider using drip irrigation or soaker hoses to deliver water directly to the soil. Give priority to young or newly planted specimens, potted plants, and those with high water needs.
Apply a layer of organic mulch, such as wood chips or straw, around your plants. Mulch helps retain moisture in the soil, reduce evaporation, and prevent weed growth. It also keeps the soil temperature more stable and protects the roots from extreme heat.
Shade sensitive plants using cloth, row covers, or even umbrellas. This can help prevent sunburn and heat stress.
Adjust fertilization: Avoid applying high-nitrogen fertilizers during extreme heat, as they can encourage lush growth that is more susceptible to heat stress. Instead, opt for slow-release or organic fertilizers to provide necessary nutrients without overstimulating growth.
Prune or thin out crowded plants to improve airflow and remove any dead or diseased plant material promptly. Good air circulation can help cool down the garden and prevent fungal diseases.
Harvest ripe fruits and vegetables promptly to prevent them from becoming overripe or damaged by excessive heat.
Move potted plants to shaded areas or indoors, if possible, to shield them from direct sunlight and extreme heat. Grouping pots together can create a microclimate that helps retain moisture and reduce heat stress.
Be vigilant against pests and diseases: Heat-stressed plants are more vulnerable to pests and diseases. Regularly inspect your garden for signs of infestation or disease and take appropriate action promptly.
