More Harm Than Benefit: Garden Plants That Absolutely Cannot Stand Ash Fertilizer
Ash is an excellent fertilizer for many plants, which can also protect them from diseases and pests.
But there are crops that do not like this product. First of all, those that require high soil acidity with a small alkali content.
Since wood ash alkalizes the soil, this fertilizer is not suitable for these plants.
An expert of the online publication BelNovosti, agronomist, and landscape designer Anastasia Kovrizhnykh named crops that are best not to be fed with ash.
If we talk about ornamental plants and flowers, then ash is not recommended for thuja, juniper, dwarf pine, and certain varieties of spruce.
As for flowers, the same recommendation applies to asters, hydrangeas, azaleas, delphiniums and some others.
There is no need to “treat” sorrel with ash, otherwise it will become frail, the leaves will quickly turn yellow, become rough and thin, and the seeds will stop developing.
Radish is a little less capricious in this regard, but only a little. Experts recommend using ash in minimal quantities before planting.
You shouldn't feed melons with ash, otherwise, by alkalizing the soil, you will provide them, especially watermelons, with an acute deficiency of nutrients.
