Heatwave is a hot, dry and sunny period which usually lasts for a few days. Heatwave can cause a lot of damage to plants. Plants are sensitive to high temperatures.
The best way to protect your plants from heatwave is to use a sprinkler system, which can provide plants with regular water. You should also take steps to prevent the soil from becoming too dry. If the soil is too dry, it will not be able to hold any more moisture. This could make the plants very thirsty and weak. It could also lead to problems like fungal diseases. You could use a watering can or hose to wet the soil around your plants, but do not leave them standing in water for long periods of time. When using a sprinkler system, you should keep the nozzle at a height that gives your plants enough water. The nozzle should be about 3 feet above the ground. You should turn on the sprinkler system when the temperature outside rises above 25°C. The water flow rate should be set to about 50-100 drops per minute. This will give your plants enough water to survive. You should also turn off the system if the temperature falls below 20°C.
