Potting On Chilli Plants
"When you pot on a chilli plant, you’re giving it room to stretch, strengthen, and become everything it’s meant to be."
As your chilli seedlings grow, they’ll eventually outgrow their starter pots or trays. Potting on (sometimes called transplanting) gives them more space, fresh nutrients, and stronger roots, setting them up for healthy growth and a bigger harvest.
When to Pot On
-
Seedlings usually need potting on when they have 3–4 sets of true leaves.
-
If roots are visible through the drainage holes or the plant looks cramped, it’s time.
-
Avoid waiting too long, overcrowded roots can slow growth.
Choosing the Right Pot
-
Size up gradually: move from small starter pots to medium containers (7–9 cm), then larger ones as plants mature.
-
Drainage is key: always use pots with holes at the bottom.
-
Material: plastic pots retain moisture, while terracotta breathes and helps prevent overwatering.
Soil & Compost
-
Use a light, well‑draining compost mix.
-
Adding perlite or sand improves aeration.
-
A balanced compost with slow‑release nutrients supports steady growth.
How to Pot On
-
Water lightly before transplanting, this helps the soil hold together.
-
Gently remove the seedling, holding by the leaves (not the stem).
-
Place it in the new pot, filling around with fresh compost.
-
Firm the soil gently, but don’t compact it too much.
-
Water in well and place somewhere warm and bright.
Aftercare
-
Keep plants in a warm, sheltered spot while they adjust.
-
Avoid direct, harsh sunlight for a few days to reduce stress.
-
Water regularly, but don’t let pots sit in soggy soil.
-
As plants grow, you may need to pot on again until they reach their final container size.
Tip
Potting on in stages helps chillies develop a strong root system. Jumping straight to a very large pot can leave roots sitting in wet compost, which slows growth.
