After all, you don’t want your hard-planted tomatoes and cucumbers to wilt and burn, do you? So how can you counteract the heat waves and how often should we water the plants in the heat?

How to protect the plants in the garden from heat?
The fact that it sometimes gets quite hot in the summer is actually nothing new. But if the temperatures stay above 30 degrees for several days in a row, then it is called a heat wave. Unfortunately, the long-term climate outlook suggests that we need to significantly improve our hot weather gardening skills. So, in order to get your herbs, flowers and plants through midsummer without damage if possible, amateur gardeners should know how best to protect the garden from heat. However, different plants also tolerate different temperatures. While vegetables such as radishes, broccoli, cabbage, pak choi or leaf lettuce prefer cooler soil temperatures, temperatures up to 30 degrees are optimal for summer vegetables and fruits such as tomatoes, peppers and peaches. Regardless of variety, young plants are more susceptible to sunburn and heat stress, and during a heat wave it’s best to bring them indoors.
Protect plants from heat with mulch
What protects our plants from the cold in the winter months has the exact opposite effect in the summer: a thick layer of mulch is one of the most effective ways to protect plants in the garden from heat. Mulching protects the soil from the sun’s strong rays and holds water much longer. In addition, mulching prevents the soil from heating up too much and keeps plant roots cool. To protect the garden from the heat, cover the soil with a thick layer of wood chips, bark mulch or grass clippings.
Provide some shade
To keep your plants from burning and to protect the garden from the heat, provide adequate sun protection. Especially during the midday heat from 11 a.m. to 4 p.m., cover plants and move potted plants into the shade. Whether you stretch white bed sheets over them for this purpose, buy a special shade cloth, or use a large parasol, there are plenty of ways to create shade in the garden. However, it’s important that you position the material so that it blocks sunlight, but still allows good airflow for the plants. While companion planting is more commonly used to repel pests or encourage pollinators, it’s also a great option for protecting plants in the garden from the heat. To do this, plant tall and heat-tolerant plants around tougher and more delicate varieties.
Using ground covers to protect the garden from heat
Various ground covers are not only a visual eye-catcher in the garden, but can also help keep the soil moist and absorb heat. For this purpose, it is best to choose evergreen and low-maintenance ground covers that can withstand dry periods well. To create quick cover, it’s best to plant groundcovers close together.
Do not cut or plant garden plants in hot weather
Gardening tasks, such as pruning, fertilizing and transplanting, always put stress on our plants. So if you want to protect your garden from the heat, it’s best to avoid doing so during the summer heat. Leave your garden plants alone for now and wait until temperatures drop below 30 degrees. You should also avoid cleaning out faded plants during the heat – these can actually serve as additional protection, preventing sunburn.
Protect potted plants in the summer
Potted plants cut a great figure in the garden and are a real eye-catcher. However, they are also the first to dry out during a heat wave. To protect them from the heat, it’s best to place them in full shade or bring them indoors on particularly hot days. In addition, the containers lend themselves to dry out faster and therefore it is important to water potted plants in midsummer, at least once or even twice a day.
Protect garden from heat: Watering plants properly in the summer
To protect the garden from the heat, we need to water our plants regularly – it makes sense, right? However, things can go wrong in the process, and you can’t overdo it – too much water can actually worsen soil conditions. First, gently push the soil apart and if the soil still feels moist, then watering can wait. The best time to water plants in mid-summer is early morning between 5 and 6 am. During this time, plants are still cool from the night and can better withstand the higher temperatures during the day. In the evening, on the other hand, the plants are very heated and cold water in this case acts as a shock. If there is no other way, and you need to water in the evening, then it is best to use stale and lukewarm water for this purpose.
