Watering water for the garden does not have to come from the tap. Rainwater is expensive and too bad to seep away unused in the ground


a hot summer means one thing above all else for garden owners: 

lots of watering! So that the weather doesn't eat a too big hole in your wallet, 

you have to think about how you can save water in your garden. 

Because even though most larger gardens already have a rain 

barrel, flowers, shrubs, trees and hedges are still watered with tap water in many places. 

With water prices averaging just under two euros per cubic meter, 

this can quickly become expensive. 

With some information and the right technology, 

water consumption during watering can be reduced significantly.

How can you save water in your garden?

  • Using lawn sprinklers at the right time
  • Do not cut the lawn too short in summer
  • Mulch mowing or spreading of bark mulch
  • Choose steppe or rock garden plants for sunny places
  • Collect rainwater in tons or cisterns
  • Chop vegetable beds regularly
  • Watering plants in the root area
  • Expanded clay and glazed pots for potted plants

1. use lawn sprinklers at the right time

If you water your garden at the right time, 

you can actually save water: Studies have shown that when watering the lawn at noon, 

up to 90 percent of the water evaporates unused. 

Better are the morning and evening hours. 

This is when evaporation is at its lowest and the water reaches 

where it is really needed: the roots of the plants.

2. do not cut the lawn too short

A green lawn needs a lot of water, especially if it is rasped short. 

Therefore, if you set the cutting height of the mower 

higher during the hot summer months, you will need to water less often.

3. save water by mulching in the garden

Bark mulch protects against evaporation and at the same time keeps weeds in check


Many modern lawnmowers can also mulch mow in addition to mowing and catching. 

In doing so, the lawn cuttings remain chaffed on the surface and thus reduce evaporation. 

Even in perennial beds or under trees and shrubs, 

a layer of bark mulch keeps the moisture in the soil. 

Special mulch films also help to save water in the kitchen garden. 

Due to the cover, a constant climate prevails under the film, 

which benefits the plants and significantly reduces evaporation.

4. choose suitable plants

Place particularly thirsty plants such as hydrangeas 

and rhododendrons only in semi-shady places. 

On dry, sunny locations they would only wither. 

In very hot locations in full sun, you should only place 

very robust steppe or rock garden plants that can get by with 

little water. Deep-rooted plants such as cherry laurel, yew, 

roses or lupines supply themselves with water from the lower layers of the earth during drought. 

Especially when selecting trees and shrubs, 

it is therefore worthwhile to consult with a tree nursery in your region before planning the planting.

5. use rainwater to save water

Collecting rainwater has a long tradition in gardens: 

with its low pH value, rainwater is better for rhododendrons 

and bog plants than the often calcareous tap water anyway. 

For small gardens a rain barrel is worthwhile, for larger gardens 

cisterns with a capacity of several thousand liters are a sensible investment. 

Complete solutions with a domestic water circuit at the house are also possible.

6. chopping saves watering in the garden

Work your vegetable beds regularly with a hoe and cultivator. 

This will keep weeds within limits and the soil will not dry out so quickly. 

The equipment destroys the fine water channels (capillaries) 

in the uppermost layer of soil and thus reduces evaporation. 

A good time to use them is after prolonged rainfall, 

when the soil has absorbed a lot of water and the surface is silted up.

7. watering plants in the root area

Water sufficiently near the roots


Do not use a thin spray for watering beds, 

but water the plants directly in the root area if possible. 

Do not cover the whole plant, as the water on the leaves will 

evaporate and can lead to burns or fungal infections. 

Water less often but vigorously, lasts longer than often and little.

8. expanded clay stores water

Fill balcony boxes with a layer of expanded clay before inserting the balcony plants. 

The clay stores water for a long time and can also 

release moisture to the plants during dry periods. 

This not only saves water, but also brings your plants well over hot days.

9. choosing the right flower pots

Terracotta is good for the plants, but not for your wallet

Unglazed terracotta pots are very attractive on terraces and balconies, 

but the clay surface also evaporates a lot of moisture. 

The cooling effect is good for the plants, but burdens the water bill. 

If you want to save water, place water-needy potted plants in glazed ceramic pots. 

Basically, you should make sure that the pots and tubs 

for the balcony and terrace are large enough so that 

the soil does not dry out immediately on warm days.
