Of course, with these grown one must wait until after the ice saints with the distribution in the open air. It is different with the cold lovers. Due to the cold nights and lack of warming of the soil, it is only now that it makes sense to plant cold-loving plants such as parsley, chervil, borage and dill. These will be placed in rows. Chervil has a very fast cultivation time. It is a universal root herb, which is traditionally used especially in soups.
Sowing of robust summer flowers such as gold poppies and marigolds can also begin. Carrots germinate already at a soil temperature of 5 to 7°. The early sowing is intended for the summer harvest. Carrots, which are needed for storage, are sown later. Lettuce, radishes and kohlrabi also want it cool rather than hot. Covering the tree with fleece offers many advantages. The plants are protected from the weather and grow much faster. The fleece is taken off only for hunting and separating. An old method is to put canning jars over lettuce plants on frosty nights. This creates a mini wax house. Lettuce varieties that are intended for the outdoors, such as the time-honored variety maikonigin, do not do well in the greenhouse. It is too warm for them here.
Zucchini and cucurbits can be pre-cultivated now in pots by the window. Both need later nutrient-rich soil. Radishes fit into the smallest garden. The best way to cultivate them, if space allows, is to plant them in rows between lettuce and vegetables.
All summer bulbs and tubers can now be planted on the spot. These include monbretias, peacock lilies and gladioli. Also for the nasturtium now comes the sowing date as a pre-culture in pots. This summer flower grows quickly and bleeds until frost. In addition, the leaves can be used as a food supplement. The effect is blood purifying like the barlauch.
