A huge mistake gardeners make when feeding yellowing garlic: what gardeners do wrong
Many gardeners associate the spring yellowing of garlic leaves with a lack of nitrogen and try to correct the situation by actively applying nitrogen fertilizers.
Why this is a mistake and how to prevent yellowing of garlic leaves, says Anastasia Kovrizhnykh , an expert of the online publication Belnovosti, agronomist and landscape designer.
How to Prevent Garlic from Turning Yellow
Of course, it is necessary to feed garlic with nitrogen fertilizers in the spring, but do not overdo it.
Garlic leaf tips turning yellow early in the season are due to a sulfur deficiency, not a nitrogen deficiency.
Low temperatures in spring prevent garlic and other sulfur-dependent crops from absorbing sulfur from the soil.
Therefore, at the beginning of the season it is necessary to additionally apply sulfur-containing fertilizers.
The largest amount of sulfur is found in ammonium sulfate, potassium magnesium sulfate, and potassium sulfate. Sulfur is also present in sulfoammophos and superphosphate.
