Knowing when to pot on chilli seedlings is not an exact science. I like to repot the chilli seedlings when they have developed their first true set of leaves like the seedlings pictured below.
My favourite method of planting chilli seedlings is to use module trays. This makes transplanting and potting on the seedlings much easier once they reach the appropriate size. This minimises any risk of damaging the root balls of the seedlings.
I raised the chilli seedlings pictured below on a south facing window sill. I planted the seed on the 24th February – germination took approximately 2 weeks. Because I wasn’t using any artificial lights or growing these in a greenhouse the seedlings became a little leggy. This isn’t a big issue as when potting them on I like to pot them a little bit deeper in the soil. The photo below was taken roughly 1 month after sowing the seeds.
At the above stage I will typically pot the seedlings on in to pots about 3″ in diameter. By using module trays you can simply apply some pressure under the module and pop out the seedling along with the whole rootball ready for transplanting to the next pot. Next simply fill the remainder of the pot with some fresh compost and water them in to ensure the fresh compost gets in good contact with the seedlings roots.
Knowing when to repot chilli seedlings is only half the battle. For the best success you need to provide them with sufficient light and heat. If your seedlings are leggy like the ones in the photo above it is a sure sign that the plants need some more light. In the case of the above plants. I moved them out to the greenhouse after potting them on to ensure they got a lot more light.
The Aji Lemon plant above appeared in the first photo above, approximately two months after being pricked out. I initially potted it into a 3″ pot before moving it up to it’s current 5″ pot.
Since I moved the plant to the greenhouse it has become more bushy. You can see more lateral shoots coming out between the main stem and the leave nodes. This is always a good sign the plant has enough light.
Thank you for sharing.
