When it’s a deficiency

Yellowing between veins signals iron or magnesium shortage. Uniform fading of older leaves indicates nitrogen deficiency.

When it’s natural aging

Lower leaves turning yellow while upper ones stay green is normal. Plants shed older foliage to focus energy on new growth — especially after seasonal changes.

Fix & feed

Use a balanced houseplant fertilizer monthly during growing season. Trim yellowed leaves to stimulate healthy new shoots.
