The summer lilac is considered an extremely undemanding shrub that thrives on almost any soil - the prerequisite is, however, that it is sunny enough and the soil is loose and permeable. However, if the plant gets yellow leaves, this is an unmistakable sign of its malaise. However, these can have different causes.
Yellow leaves on summer lilac can have different causes
Yellow leaves on the buddleia and what you can do about it
The actually quite robust summer lilac gets yellow leaves when it does not like the soil, the location or the care. Don't make the mistake of watering the shrub due to suspected drought - you're more likely to deal the deathblow. Instead, one or even more of the following reasons are more likely:
- Waterlogging - often due to heavy soil. You can do that: dig up lilacs and move them or improve the soil with sand and grit (€46.95).
- Location too dark - Buddleia needs a lot of sun and warmth, which is why it quickly develops yellow leaves in a location that is too dark. In this case, only a transfer will help.
- Lack of nutrients - The fast-growing summer lilac soon lacks the required nutrients, especially on loose, sandy soils. Feed it regularly, but at least at the beginning of the season, with compost, horn shavings (€32.93) and stable manure.

Too small a planting distance can also mean that the summer lilac does not feel comfortable.
