Know What’s Wrong With Your Plant

It’s very frustrating to nurture a plant, sometimes from seed, and see it start to wilt away or turn strange colors! Fortunately, Diana Maranhao, author of Rocky Mountain Fruit & Vegetable Gardening shares her guide to diagnosing the problem. It turns out that you’re not the only one that could benefit from some extra nutrients every once in a while!

Nutrient Deficiencies

If your plant leaves are turning weird colors (purple, yellow), they might have nutrient deficiencies. Nutrient deficiencies cause highly predictable results, and it’s usually possible to diagnose deficiencies by looking at the plant.

This diagram shows the symptoms caused by the most common nutrient deficiencies.

Here’s a chart you can print out and take with you for reference!

  • New Leaves

Iron: Young leaves are yellow and white with green veins. Existing leaves remain green.

Calcium: New leaves misshapen or stunted. Existing leaves remain green.

  • Older Growth

Potassium: Yellowing at the tips and edges, usually in younger leaves. Dead or yellow patches develop on leaves.

Nitrogen: Upper leaves are light green where lower leaves are yellow. Bottom or older leaves are yellow and shrivelled.

Carbon Dioxide: White deposit on leaves. Stunted growth, and plants die back.

Manganese: Yellow spots and/or elongated holes between veins.

Phosphate: Leaves are darker than normal and loss of leaves.

Magnesium: Lower leaves turn yellow from outside going in. Veins remain green.
