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.

Planting information
In areas with mild winters, onions are sown in spring and summer, at temperatures of 15 to 25°C from February to June. In northern, cooler areas, sowing takes place at identical temperatures in spring from March to May.
In order to utilize the potential of each individual plant, we recommend pre-growing in small boxes with subsequent pricking out or letting them grow in the breeding boxes. The plants are ready to plant when they have reached a height of 20 cm. As a tip: If you prefer pre-cultivation without pricking out, shorten the plants by 1/3 at the roots and leaf tips before planting out. This stimulates the growth of the plants. Then plant as usual at planting distances.
This variety prefers a sunny location with sufficient water, as well as a calcareous, nutrient- and humus-rich heavy clay soil.
The onions are ripe when the leaves turn brown and dry out, but they can also be harvested beforehand for fresh consumption.
