ABOUT
Magnesium is a key element in chlorophyll and its deficiency affects mainly older leaves. A typical symptom is an interveinal chlorosis - yellowing between leaf veins. Another sign is leaves turning red-brown-purple, their necrosis, and dropping off.
How to treat?
- Biological
Replant the plant into fresh soil rich in nutrients.
Add manure or compost to the soil.
- Chemical
Apply missing nutrients to the plant foliage (suitable for quick help). Follow the instructions on the chosen product to prevent excessive fertilizer usage. Apply magnesium fertilizer as a foliar spray (e.g. magnesium sulfate, known as Epsom salt).
Apply missing nutrients to the soil (suitable for long-term help). Follow the instructions on the chosen product to prevent excessive fertilizer usage. Apply magnesium fertilizer to the soil (e.g. magnesium sulfate, known as Epsom salt).
- Disease prevention
Apply fertilizer regularly. Fertilizing is especially important during spring and summer.
Change the soil regularly. Plants should be repotted when the soil is compacted, depleted of nutrients, and no longer retains water.
Choose suitable neighboring plants. Plants with similar nutrient requirements should not be planted close to each other.
