How Plants Cope with Heat and How to Care for Them
How Plants Cope with Heat
When the temperature rises above 85 degrees Fahrenheit, plants can suffer from heat stress. This is because plants need water to survive, and heat causes water to evaporate from the leaves. If plants don’t get enough water, they will wilt and eventually die.
Some plants, like succulents, are well-adapted to handle heat because they store water in their fleshy leaves. However, most plants do not have this luxury. As a result, they will show signs of heat stress, such as:
- Wilting
- Dryness
- Yellowing of the leaves
- Leaf drop
- Blossom drop
- Blossom end rot
How to Care for Plants in Hot Weather
There are a few things you can do to help your plants cope with heat stress:
- Water your plants more often. Plants need more water in hot weather to replace the water that evaporates from their leaves. Water your plants deeply and regularly, especially during the hottest part of the day.
- Mulch around your plants. Mulch helps to conserve moisture in the soil and keep the roots cool. Apply a layer of mulch around your plants, but be sure to keep it away from the stems.
- Provide shade for your plants. If possible, move your plants to a shadier location during the hottest part of the day. You can also use shade covers to protect your plants from the sun.
- Fertilize your plants regularly. Fertilizing your plants helps them to stay healthy and strong, which makes them more resilient to heat stress.
- Watch for signs of heat stress. If you see any signs of heat stress in your plants, take steps to address the problem immediately.
Tips for Specific Plant Types
- Container plants: Container plants need to be watered more often than plants in the ground, especially in hot weather. Water your container plants daily, or even twice a day if the temperatures are very high.
- Vegetable crops: Vegetable crops are particularly susceptible to heat stress. If you live in a hot climate, it’s important to choose heat-tolerant varieties. You should also water your vegetable plants deeply and regularly, and mulch around them to conserve moisture.
- Fruit trees: Fruit trees can also suffer from heat stress, especially if they are young. Water your fruit trees deeply and regularly, and mulch around them to keep the roots cool. You can also paint the trunks of your fruit trees white to reflect the sun’s rays.
By following these tips, you can help your plants cope with heat stress and thrive even in the hottest weather.
Additional Tips
- If you have any questions about how to care for your plants in hot weather, consult with a local nursery or garden center.
- Be patient. It may take some time for your plants to adjust to the heat.
- Don’t give up on your plants if they show signs of heat stress. With a little care, they can recover and thrive.
