Summer lilac is not growing - What to do?
Summer lilac is considered an extremely undemanding shrub that literally "grows like weeds". In fact, you have to cut down the plant regularly, so that it forms many new shoots and thus flowers - and not verkahlt from below. Sometimes, however, the summer lilac does not really want to grow, which is always a clear sign that it does not really like the location, the soil and / or the care.
Causes of low growth
If the summer lilac does not grow, it can have different causes. It is important that you go first to the search for the specific cause and not immediately take action. Only when the reason is found, it can be eliminated - with the result that the shrub finally grows as desired.
Wrong location
One of the most common reasons for lack of growth in summer lilac is a too dark location. The shrub needs plenty of sun and warmth - if it is in partial shade or even in the shade, it does not feel well and does not grow as desired. The reason for this is the lack of photosynthesis: The plant simply can not convert enough light into sugar, which in turn is needed for growth.
nutrient deficiency
In fact, nutrient deficiency can be another reason for the miserable growth. Although the summer lilac prefers a well-drained, sandy soil, it needs a regular supply of compost, horn shavings and possibly manure. At best, use this natural fertilizer twice a year - once for budding and once in early summer - carefully in the root disk.
Too heavy soil / waterlogging
If the soil is too heavy and / or even too wet, not only does growth suffer. Quickly put the summer lilac in a more suitable ground or improve the existing with the intermixing of sand, grit and possibly compost.
Summer lilac frozen in winter
Buddleja davidii, in particular, is thriving reliably from its roots each year, despite frostbitten shoots - as long as they have not been damaged by the frost themselves. For this reason, you should always cover the root disc with a light winter cover, for example, with fir or spruce branches, and pack bucket specimens frost-proof.
Tips
Diseases such as mildew, which increases in wet summers, can also negatively affect growth. In the example mentioned often only helps a strong pruning and treatment with a brew of horsetail.
