Growth

Stunted Growth in Young Pepper Plants

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

The plant grows very slowly or barely at all after transplanting, with small, sometimes purple-tinged leaves and a generally weak appearance compared to expected growth for its age.

Potential Causes

  1. 1Cold soil or air temperatures slowing root development and nutrient uptake
  2. 2Phosphorus deficiency, often signalled by a purple tinge on leaf undersides
  3. 3Transplant shock from root disturbance during potting up
  4. 4Pot-bound roots restricting further growth

Solution Steps

  1. 1Ensure daytime temperatures stay above 18�21�C and avoid exposing young plants to cold drafts or cold soil.
  2. 2Apply a balanced fertiliser with adequate phosphorus if purple leaf tinge is present.
  3. 3Check the root ball for pot-bound roots circling the container, and size up if necessary.
  4. 4Be patient with recently transplanted seedlings � most recover within 1�2 weeks once roots re-establish.

Prevention Tip

Wait until soil and air temperatures are reliably warm before transplanting outdoors, and handle root balls gently to minimise transplant shock.
