Boxwood is one of the plants that needs a lot of moisture for he althy growth. The evergreen tree feels most comfortable in fresh and nutrient-rich, but never wet, soil. Depending on the variety, boxwood also has little tolerance to heat and drought. Mulching - for example with bark mulch - keeps moisture in the soil longer and thus protects against drying out.
Is bark mulch suitable for boxwood?
Bark mulch is suitable for boxwood because it retains moisture in the soil and protects it from drying out. It also prevents weed growth and ensures nutrient-rich soil. High-quality coarse bark mulch from specialist retailers is recommended.
Bark mulch retains moisture in the soil
Now bark mulch has other advantages in addition to moisture protection. This will hinder the growth of weeds unless you use the already half-rotted material from the hardware store. Instead, use high-quality, coarse bark mulch (€29.00 on Amazon) from specialist retailers. You can check its quality with your nose: the lower quality the bark mulch, the more intense it smells - up to and including very unpleasant, moldy scents. High-quality bark mulch, on the other hand, has a pleasant, woody smell.
Tip
You don't need to worry about acidification of the soil due to bark mulch: According to new scientific findings from research by the Quality Association for Substrates for Plants, this risk does not exist.
