If the boxwood turns yellow, there can be various reasons behind it. In many cases it is the result of a previous lack of water or nutrients, sometimes the roots can also be damaged. This is how you can quickly remedy the situation.
A lack of nutrients can be the reason for the boxwood turning yellow
lack of water
Buchs has a fairly high water requirement and cannot cope with prolonged drought. Therefore, in hot and dry phases, make sure to water specimens planted in the garden regularly. If the boxwood is in a pot, on the other hand, it needs some liquid from time to time, even in winter. So don't forget to water the potted plants that overwinter on the balcony or terrace on frost-free days! Box trees in sunny, warm and sheltered locations are particularly at risk of drought damage.
waterlogging
As little as the Buchs likes dryness, it is even less able to cope with excess moisture and, above all, with waterlogging. Prevent by providing both garden and potted specimens with good drainage. The garden soil should be loose, permeable and humus. Also, do not water the box excessively and "by feel", but check the necessity with a simple finger test: If the substrate or the soil is dry a few centimeters deep, then fresh water must be given. Mulch the soil, for example with bark mulch, so that the moisture is stored longer and does not evaporate.
nutrient deficiency
The Buchs has a big appetite and is therefore dependent on a regular supply of a balanced nutrient cocktail. Mature compost is best, which is administered together with horn shavings (32.93€) and primary rock flour in April and June. A long-term fertilizer (if possible box tree fertilizer or green plant fertilizer) is also useful here.
tips
Another reason for yellow leaves on the boxwood can be damage to the roots caused by pests living in the soil, such as voles, broomsticks, etc.
