Watering plants in a targeted way

When it comes to watering your plants, it is better to water less often but more thoroughly to give it a chance to seep in and for the roots grow deep. You should apply 10 - 30 litres per square metre. Drive a spade into the ground and pull it back slightly. Then you will be able to see how far the water was able to penetrate into the ground.

In the summer, the earlier in the day that you apply the water, the better it is for lawns, beds and plants. Because the water soaks in well early in the morning and can be taken up quickly by the roots. Watering around midday causes most of the liquid to evaporate in the heat before it can soak into the ground. Furthermore, droplets on the leaves can act as a magnifying glass for the sun. The evening is also not ideal, because the leaves stay wet overnight and this invites fungal infections, mildew and snails.

How much water do plants need?

This can vary depending on plant and location. You will need to water more in sunny areas than in the shady regions of your garden. Also, some plants are especially thirsty, such as fuchsia. As a general rule, the amount of water to be applied increases with the size of the leaves. Seedlings and newly planted items require water every day.

Only water just before the leaves start to droop on your plants. This forces them to form long roots so that they can fetch moisture deeper from the earth and as a result, the plants will become more robust.

How thirsty is your lawn?

In a drought it is best to soak the lawn area once or twice a week, right down to the roots. We recommend around 10 to 15 litres of water per square metre of lawn. Grass under trees also needs more water because the trees are also absorbing much of the moisture.

Oscillating and rotating sprinklers

Oscillating sprinklers are ideal for regularly watering large areas. Simply connect the hose, turn on the tap and the water is distributed evenly over the area. The same applies to rotating sprinklers, which are mostly used on lawns. They wet over a full circle, but can also be set to water only an arc, depending on the model and the setting. If your garden hose is too short or your garden is too long, use a WOLF-Garten hose reel trolley.

The watering can still has its place in the garden

A watering can allows you to control which parts of your garden you will water, and how much. You can use the rose to direct less water evenly and gently onto small and delicate plants. Or take off the rose and water with a hard jet and a lot of liquid at once. Another advantage is that you can direct the water to only wet the soil, preventing water from forming droplets on the leaves of plants.
