Garden in summer: how to protect the lawn and plants from heat and drought? 5 useful care tips

For many, the garden is a perfect place to relax in the summer. However, for your own oasis to survive long periods of heat, good care is crucial. We explain how to protect the lawn and plants from heat and dryness and strong rays of the sun.

How to protect lawns, potted flowers and plants from heat: Here’s what you can do!

Garden in summer choose heat tolerant plants (1)

Most garden plants feel particularly comfortable at temperatures around 25 degrees Celsius. However, heat waves are no longer a rarity in summer. To survive these, the garden should be suitably prepared for the high temperatures. We explain what you can do against heat in the garden.

Water properly in the heat and save water

Watering properly in the heat how to save water

In hot weather, plants in tubs, pots and planter boxes are particularly at risk. Mainly because the small volume of soil can store smaller amounts of water. Plants that prefer full-sun locations but have large fleshy leaves could also die in dry conditions. The same applies to all flowers, shrubs and perennials that are in bloom. Even vegetables in raised beds or herbs in the herb spiral need plenty of water to get through the heat wave in good health.

The heat itself, i.e. the high temperatures, does not bother most plants. However, direct sunlight is problematic. Just the midday sun could burn the plants and accelerate the evaporation of water.

Water plants in raised beds when it’s hot:

  • Better once, but copiously, than several times a day, but too little. It is best to water the plants in the late afternoon. This way you can prevent the water from evaporating quickly.
  • Do not water the plants from above, as wet leaves can quickly burn under the strong rays of the sun the next morning. Water directly around the root area.

Water potted flowers and container plants properly:

  • It is best to use decalcified, lukewarm tap water or rainwater.
  • Water twice a day – early in the morning and late in the evening.
  • Water directly from below, always making sure that the water does not run out. This is because, especially in tubs, nutrients are gradually flushed out with leaking water. This could lead to nutrient deficiencies.

Water vegetables properly in summer:

  • To save water in the kitchen garden, you can opt for a beaded hose. This has the advantage of distributing water evenly over a larger area.

How do I protect my garden from drought in the summer?

Protect garden from drought with mulch useful tips

Humus-rich soil retains water: provide soil with horn shavings or other organic humus-rich fertilizers. In summer, it is very important that plants get enough water. A humus-rich soil prevents evaporation too quickly and has excellent storage capacity.

Mulching in summer prevents evaporation: Furthermore, it is a good idea to mulch the flower bed. A layer of mulch about 1 cm thick will prevent water from evaporating too quickly on hot summer days.

How to prevent plants from burning in the heat

Plants in the heat: Young plants in particular should be protected from strong rays of the sun. Before planting them in the garden, even true sun worshippers should first be placed in an off-sun location. Young plants need a lot of water anyway, so in hot weather you should water them extensively.

Properly care for potted plants in drought tips


Move potted plants in the afternoon: If they are planted in containers or pots, then you can move them to a shady or semi-shady place in the afternoon.

Fleece or shade net as sun protection: Outdoor plants can be protected from strong sun rays by fleece. The most important thing here is that the plants are aerated several times a day.

Lawn care in summer

Lawn care in summer what to consider in drought

When summer temperatures rise above 25 degrees Celsius, the growth of grasses is significantly slowed. Prolonged heat may even cause the lawn to temporarily retire.

Mow the lawn less frequently in hot weather: In hot weather, you should therefore mow the lawn less frequently, because it also grows much more slowly. Also, let the lawn get a little higher, around 7 cm is optimal. This will protect the soil from drying out.

Which plants are heat resistant?

Especially in summer is the right time to make a garden sketch and mark on it the different areas. Where does the sun shine for eight hours a day? Which corners are in the shade? This way, you can plan the planting of new species next spring. A tip: choose plants with small leaves. Plants for rock gardens also do well because they can handle direct sunlight and nutrient-poor soil. Deep-rooted plants are better for prolonged dry periods, because they can reach underwater and moisture from the lower layer of soil.

The summer garden pleases the eye with its splendor of flowers. But in order for plants to thrive in the heat, there are a few things you should keep in mind when caring for them. Proper watering, regular mulching, as well as sun protection can protect the flowers and crops from burning.
