Help, My Tomato Leaves Are Yellowing (Easy Fixes)

Common Causes for Yellowing Tomato Leaves

Yellowing leaves on your tomato plants can be a real head-scratcher. Trust me, I’ve been there.

Overwatering

Tomato plants love water, but too much can be a problem. Overwatered roots can't breathe, leading to yellow leaves.

My rule of thumb? Water deeply but infrequently. Let the top inch of soil dry out before watering again.

Underwatering

Conversely, underwatering can stress the plant. When thirsty, the leaves yellow in protest.

Check the soil moisture with your finger. If it’s dry below the first knuckle, it’s time to water.

Nutrient Deficiencies

Tomatoes are nutrient hogs. A lack of nutrients can cause yellowing leaves.

Certain deficiencies, like nitrogen or magnesium, often manifest as yellowing leaves with green veins.

Try a balanced, slow-release fertilizer. In my experience, a little fish emulsion works wonders.

Pests and Disease

Pesky pests can also be culprits. Aphids, whiteflies, and spider mites suck sap and cause yellow leaves.

  • Inspect the underside of leaves regularly.
  • Use insecticidal soap or neem oil if needed.

Disease can be another cause. Blight, both early and late, can turn leaves yellow.

Practice crop rotation and space plants well to improve air circulation. Remove and dispose of infected leaves.

Environmental Stress

Sometimes, it’s just the weather. Cold snaps or intense heat can stress your plants.

During a heatwave last summer, my tomato leaves yellowed in protest. Shade cloths helped them recover.

pH Imbalance

Tomatoes prefer slightly acidic to neutral soil. A pH imbalance can lock out nutrients.

Test your soil. Amend with lime to raise pH, or sulfur to lower it.

Transplant Shock

If you recently planted your tomatoes, yellowing leaves might be due to transplant shock. Young plants are especially susceptible.

Be gentle when transplanting. Water well after planting, and consider using a root stimulator.

Practical Steps to Take

  1. Check soil moisture and adjust watering habits.
  2. Fertilize with a balanced formula.
  3. Inspect for pests and treat accordingly.
  4. Amend soil pH if needed.
  5. Protect plants from extreme weather.

Tomatoes can be finicky but rewarding. Observe, adjust, and soon your plants will be lush and green.

Happy gardening!
