Plants need water in the summer regularly, even if it has rained, because usually the amount of rain is not enough. Flowers and grass do not have to be watered every day, but they do so extensively. Especially on hot days, the soil is so dry that the water drains quickly and can not seep into the soil sufficiently. As a rule of thumb: Dear once properly than several times too little pour. Thus, the plants can form deep roots and become more resistant to dryness.
Do not use a lawn sprinkler for bedding plants
Most plants should not be watered until the water shortage becomes apparent. This is particularly easy to assess in deciduous plants such as hydrangeas: when the leaves start to hang, the plant needs water. The lawn sprinkler is unsuitable for watering beds: The continued moisturization of the leaves can promote a fungal attack on sensitive plants such as roses.
Water with watering can or hose
Watering can or garden hose are much more suitable because the water only reaches the foot of the plants. For freshly set plants so-called casting rings are recommended. These are usually made of plastic and are stuck in the soil around the plant. Piling up soil can also help to collect the water around the plant so that it can slowly penetrate the roots. About two watering cans per square meter of bed are ideal.
Pearl hoses distribute water evenly
So-called perl or spray hoses are perfect for the economical yet effective irrigation of beds. Using fine sprays – for example, 13 holes per meter – the water is distributed evenly and directly into the soil and does not evaporate immediately on the surface.
Best pour early in the morning
The best time to water is early in the morning, ideally between three and five o'clock. Then it is usually the coolest and the evaporation low. Who irrigates his garden automatically, such as through hoses, can use a timer and set accordingly. Important: Never pour in the blazing midday sun or over the leaves, otherwise there is a risk of sunburn. Rainwater is best for irrigation, which can be caught in a rain barrel or cistern. Water from the pipe is often too cold. If you still need to use it, leave it in the watering can for one day.
Pour potted plants regularly
Plants in containers require particularly intensive care. In contrast to bedding plants, they can not be deeply rooted and thus reach water. The rule is: the smaller the container, the more water. Hanging baskets can even be watered twice a day in summer. Many potted plants are still limp in extreme heat. You get yellow leaves, sagging stems, burns or dried branches. Often, however, they can be saved. Wrong is over-pouring. The water usually seeps immediately through the drain hole on the bottom of the pot.
Under spreading plants, the soil is often dry
In order to revive withered potted plants, it is better to place the plant together with the pot in a bucket filled with water. However, only if the respective flower or plant pot has a drain hole. If there are no more air bubbles in the water, the earth has absorbed enough liquid. Then water the plant regularly and drain off excess water immediately.
Water the lawn extensively with lawn sprinkler
Under trees or particularly spreading plants such as large rhododendrons, box trees or conifers, the soil around the root system usually does not get enough water even after long rainy seasons. Even if the soil is superficially wet – just a few centimeters lower, the soil is dust-dry. Therefore, these areas must be poured extensively with a watering can or hose and directly at the root.
Do not mow too deeply
Who wants to keep his lawn green throughout the summer, should water him extensively. Only if the roots are optimally moisturized will it stay healthy. If the stalks do not straighten up after entering the lawn or are already turning in slightly, it is time to blow up. Also for the lawn: Too short a water penetrates only the topsoil and the water is wasted. A commercial lawn sprinkler should run about 1.5 hours. Tip: For control, place a large glass of water on the lawn and mark with a mark of about 1 to 1.5 centimeters. When this level is reached, the lawn has enough water.
