Why are my chilli plants growing slowly?

One of the biggest questions that refers people here is ‘Why are my chilli plants growing slowly?’ So I thought I’d try to give a few reasons for slow growing chillis.

Variety – some types of plant can be slow, others quicker. Try researching the specific breed of chilli pepper seeds you’ve planted.

Temperature – chilli plants grow better in warm conditions. Where possible, keep plants in a warm place and ideally use a heated propagator to germinate and grow seedlings. For most varieties, they need to be kept at a temperature above 15 degrees C otherwise the growth will definitely be disrupted.

Light – chilli pepper plants need as much light as possible, ideally natural sunlight. If you’re struggling to provide plants with enough light and are serious about growing chillis you could invest in an artificial light set up. Otherwise, a window sill with a good few hours of sunlight each day will be fine.

Nutrients – poor quality soil or a lack of nutrients will make it difficult for the plant to grow up fast and strong. You can usually tell if your plant is thirsty for nutrients by the colour of leaves.

Potting On – this is when you move your seedlings into a larger pot to allow for more growth. Some people say that if you put small plants into very large pots, they will concentrate more on growing their roots to fit the pot, than growing the plant itself. Although I don’t know if this is true, it’s probably best to make sure you gradually increase pot size over time.
