By May at the latest, everything starts to bloom and increasingly sunny and warm days draw us outside. But of course there is also more to do in the garden, such as keeping weeds and damaging plants at bay. You can find some tips and tricks for the month of May here:
During spring planting, remember that there could still be the occasional frosty night. Frosty nights can occur around the middle of May on the days dedicated (in Germany) to Saints Pancras, Servatius, Bonifatius and Sophia. They are called the "ice saints" in Germany because there was frequently a late frost on these nights during the last century. Custom says that spring weather will only be consistently mild after "Cold Sophie" (15th May) has passed. This is no longer true in meteorological terms, but May can still surprise us with cold spells. For this reason, most summer flowers and heat-sensitive vegetables such as tomatoes are only placed outside towards the end of May.
To prepare the soil for tomatoes, you can work horn meal into the earth. Tomato stakes are also placed into the ground. When the seedlings are finally set, plant the tomatoes deeply and slightly sloped to the lowest leaf shoot. This enables the stem to form additional roots.
Special films with holes or slits and fleeces are suitable for protecting young plants from the cold; they allow them to breathe. The cold protection is fixed to the edges of the beds using stones or boards and is removed during the day or for watering.
In April and May, exposed areas of soil should not be covered with mulch. Uncovered soil can warm up better during the day and give off this heat into the air during the night. If there is a frost at night, this can protect the buds from frost damage.
May is the ideal time for thinning out tightly packed seedlings. To achieve this, excess weak plants are carefully removed by pulling the top of their roots. The remaining seedlings are surrounded by soil and pressed in gently. If seedlings are very tightly packed, we recommend undertaking this thinning in several stages and always pulling the weakest plants.
Once no more frost is expected, you can take your balcony and pot plants outside along with seedlings for annuals. Do not forget to water the plants regularly and feed them if necessary.
Annual sunflowers can now be planted wherever there is still space: Between shrubs, at the edge of woody areas or even in vegetable plots. But beware: Fresh plants are a real delight for snails. You should therefore collect all snails at night until the flowers have taken hold.
