Yellowing Leaves � Nitrogen Deficiency

Commonly affects: Capsicum annuum, Capsicum chinense (Chili Pepper)

Older, lower leaves turn uniformly pale yellow first, while newer growth at the top of the plant stays green. Growth overall slows, and leaves may be smaller than expected for the plant's age.

Potential Causes

  1. 1Insufficient nitrogen in the soil or feeding schedule, especially in container-grown plants
  2. 2Heavy rain or frequent watering leaching nutrients out of the potting mix
  3. 3Root damage limiting nutrient uptake despite adequate soil fertility
  4. 4Old, depleted potting mix that hasn't been fed in several weeks

Solution Steps

  1. 1Apply a balanced, nitrogen-rich liquid fertiliser at half strength, and observe for improvement in new growth over the following week.
  2. 2Once new leaves show healthy green colour, resume a regular feeding schedule every 2�3 weeks.
  3. 3Check drainage holes aren't blocked and that the pot isn't sitting in standing water, which can indirectly starve roots of nutrients.
  4. 4If the plant is in old potting mix (over a year), consider repotting into fresh soil with fresh nutrients built in.

Prevention Tip

Feed container-grown peppers every 2�3 weeks during active growth, since frequent watering in containers leaches nutrients faster than in garden soil.
