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.

Postelein is an annual winter lettuce that comes from the west coast of North America. It was already used as a food and medicinal plant by the Native Americans at the time of Christopher Columbus. Leaves are thick-fleshed and can be eaten freshly harvested together with flowers and stems raw as a salad or briefly blanched as spinach. The closed buds can be pickled like capers or the roots can be boiled briefly in water, which develops a similar aroma to water chestnuts. The taste is fresh and mildly nutty. This variety can be harvested continuously, even in the dead of winter. As a medicinal herb, Postelein has anti-inflammatory, antibacterial effects and helps with heartburn and stomach inflammation. Can also be used as green manure.

Planting information
Postelein is sown, in areas with mild winters, in autumn when temperatures drop by 12°C or with a two-week artificial stratification, from October to February. In northern, cooler areas, sowing takes place at the same temperature in autumn or spring from September to March. Only germinates at temperatures below +12°C.
Usually the Postelein is sown in rows, like radishes.
This variety prefers a semi-shady to shady location with sufficient water and humus-rich soil. But can also be cultivated on other soils.
For a longer harvest period, care should be taken when harvesting to leave the basal leaves on the stem. Postelein prefers cooler and humid climates.
