Grapevines have a high need for nutrients because they are cut back extensively every year. Proper fertilization therefore takes up a lot of space in professional care. How to handle the topic correctly.

Professional soil analysis provides information

Experienced hobby gardeners do not administer apparently suitable fertilizer preparations to their vines indiscriminately. The rule of thumb should be heeded: As much as necessary - as little as possible. Only a well-founded soil analysis by a professional laboratory can provide certainty about the actual needs of the soil. For an amount under 50 euros you will receive a detailed result with an individual fertilizer recommendation.

The right fertilizer rhythm for grapevines

Environmentally conscious hobby gardeners steer clear of artificial fertilizers with a long-term effect in their green realm. Instead, they use a wide range of organic fertilizers. Compost, stable manure, poultry manure, plant manure, worm tea or guano come into question.(121.99€) The resulting vines score with class instead of mass. How to proceed:

  • Incorporate organic fertilizer into the bed at the beginning of the growing season in March/April
  • Administer diluted plant manure or worm tea to the vines in the bucket
  • then fertilize twice a month
  • last fertilization takes place in September with an additional dose of algae lime or rock flour

After the autumn fertilization, this year's nutrient supply ends so that the vines can mature in time before winter.

Targeted mulching supports organic fertilization

A layer of mulch keeps the soil warm and moist for longer, while at the same time releasing more nutrients. Grass clippings make excellent mulch material, while trimmed leaves should be disposed of due to the risk of infection with powdery mildew. In contrast, experienced hobby winegrowers like to use chopped vine wood and grape seeds as mulch.(239.00€) The grafting point on the vine must absolutely remain free.

The ash of the vine wood is particularly suitable for promoting frost resistance. This is rich in potassium, which specifically strengthens the cell walls of the plant tissue. Therefore, as part of the autumn fertilization, spread the ash on the plant disc in a thin layer.

tips and tricks

Ecologically oriented hobby gardeners sow green manure under the vines, such as lucerne, wild poppies or vetchling peas. These loosen the soil, release additional nutrients, reduce erosion and strengthen resistance to diseases.
