Proper watering of the garden at high summer temperatures
When casting you can make so many mistakes, because not only too little, even too much water can harm the plants very much.
Rainwater is best used for casting, which is collected in an underground cistern or in rain barrels, as it is at the right temperature, free of limescale and minerals, and barely changes the nutrient content and pH of the soil. Also, the plants need different amounts of water.
For example, you should water lawns and vegetable beds with 10 to 15 liters per square meter, the rest of the garden needs after hot days even 20 to 30 liters per square meter.
When watering trees, shrubs and perennials, note that there are deep and shallow roots.
Flachwurzler (such as maple, birch, alder, pear, cornel, elderberry, spruce, vinegar, willow, wisteria, bamboo, viburnum, thuja, forsythia, witch hazel, hydrangea, magnolia, trumpet flower, privet and almost all fruit trees) are spreading their Roots only just below the soil surface, which does not reach the groundwater. Therefore, they depend on regular rainfall.
Deep or pile root (such as oak, yew, ash, chestnut, pine, larch, linden, robinia, elm, juniper, walnut), on the other hand, their main or taproots root, with only a few lateral roots, sometimes even penetrate up to 10 m deep into the ground. which allows them to reach the groundwater in most cases and thus survive dry periods better than shallow roots.
To dampen the soil 1 cm deep, depending on soil type, about 1 liter of water per square meter is needed.
If a soil layer z. B. 20 cm deep to be moistened, then you need about 20 liters of irrigation water per square meter.
The rainfall per square meter can be good with one pluviometer to be controlled. Even when using a lawn sprinkler, a rain gauge can be used.
Is used to pour the watering Can, then you know their contents (usually 5 or 10 liters) and can pour the required amount of water per square meter.
If you irrigate the garden with a tube from a cistern or from the faucet, then one is Water meter It is very helpful to correctly dosing the amount of water simply clicked between the hose and the pouring spout or pouring shower. The following information can then be displayed one after the other on a display by pressing a key:
- Water consumption per day
- Total water consumption per season
- Water consumption per single pouring process
- the current flow rate (in liters per minute)
So trees, shrubs, perennials, beds or lawns can be poured with the required amount of water.
