Which leaves should you not use in the garden?
To prevent any risks to your garden plants, you should use autumn leaves correctly as compost. For this purpose, you should avoid some types of leaves, although it is not advisable to add the leaves of maple, eucalyptus, walnut, oleander or ivy. Most of them also contain substances that slow down the breakdown of certain components in the compost heap. The leaves of these plant species also contain toxins that can cause damage when fertilized.
For example, if you also want to add oak leaves to your compost, you should pay attention to the quantity. These affect the acidity of the soil and increase its pH value. In addition, walnut leaves contain juglone, which makes them unsuitable for mulching. There is also a lot of lignin in it, which slows down decomposition, although such foliage also requires a lot of nitrogen in the soil as fertilizer. One option is to use it as mulch at the base of strawberries, raspberries or fruit bushes. This allows you to make the soil richer in nutrients for such crops.
