Tips to reduce water use

We recommend mulching the beds.
Experience has shown that covering the ground with hay or straw can reduce evaporation by 80%. Keeping the beds evenly moist will create an optimal moist microclimate under the mulch. This not only helps the plants to grow, but also reduces the water consumption enormously. On our farm we only water every 2-3 days and irrigate a 200 m2 cultivation area in the Algarve in Portugal with 500l of water. Our beds are always moist, which promotes plant growth and crop quality.

It is also advisable to keep the beds moist at all times.
Even if the bed is not used for a certain period of time. Drying out the soil causes a huge reduction in the micro- and macro-organisms in the soil, resulting in an infertile soil.
Tests have shown that the addition of water to the entire bed is lower over a longer period of time than if it is only poured selectively. Due to the small volume of the poured areas, as opposed to the large dry volume, they dry out faster than if the entire volume of the bed were filled with moisture.
Similar to heating in an apartment.

Maintaining an energy level always requires less energy than having to reach this level again and again.

St. John's wort is a very old perennial medicinal herb that has been used as a medicinal plant since ancient times and is highly valued. St. John's wort is originally native to Europe, North Africa and Central Asia. It can now be found almost worldwide, especially on roadsides, dams and in open forests on dry and calcareous soils. The symbolic medicinal plant has a long history of use and was used for somatic and psychological ailments several hundred years ago. The striking red oil has a high proportion of the active ingredient hypericin, which is used for rheumatism, gout, tension, depression, lumbago and also injuries. It has a mood-enhancing and calming effect and is often made as a tea. The traditional burning of the herb on St. John's Day is symbolic of the sun. A bee pasture.
