Watering plants when it’s hot
In the summer, the plants and the lawn in particular suffer from excessive heat and lack of water. The plants hang upside down and the lawn looks yellow and withered. The lawn grows best at temperatures up to 20 degrees. At temperatures above 30 degrees, it hardly grows and begins to dry out. The potted plants also have a high water requirement at the moment, as the storage capacity of the pots is very low. The best time to water is early in the morning, preferably between three and five o’clock.
Water pot and tub plants regularly
Pot and container plants dry out relatively quickly in the summer because they cannot root deeply. Only regular watering will help here. Especially small pots and tubs need a lot of water. If you can’t water in the morning, only water potted plants and beds in the evening when the sun is slowly setting. Because the water droplets on the sensitive leaves act like magnifying glasses and can cause burns on the leaves.
Waterlogging of plants in pots should be avoided. Heat-sensitive pot and tub plants should be placed in a shady spot in the garden. If there are no trees or other natural shade sources, installing an awning can also make sense.
Potting soil as a water reservoir
Good potting soil is an essential part of the water management of pot and container plants: it can absorb water quickly, store it and make it available to the plants.
How much water do plants need?
Shallow-rooted plants need to be watered more often because the top layer of soil dries out faster. Other plants that develop deeper roots usually manage with less water. For a vegetable garden you need on average about 10 to 15 liters per square meter. Flowers and perennials can tolerate 20 to 30 liters per watering.
water the lawn well
Like all plants, the lawn needs regular watering in the summer to stay green. We recommend watering the lawn at least once a week. In the summer, give your lawn 10 to 15 liters of water per square meter so that the soil can hold 10 to 15 centimeters of moisture. If it is very hot for a long period of time, water the lawn up to 4 times a week. It is important to water the lawn for a long time. With short watering, the water only penetrates the surface of the soil, does not reach the roots and evaporates very quickly.
