Chilli is not as easy to form roots along the stem as tomato but if a plant has become a little rickety, pulled off on the height because of low light in relation to the temperature it is possible to recycle plant in a deep pot.
Here it is a “Carolina Reaper Hot Pepper AKA HP22B” as my mother kept in a bright window that pulled away too much in height according to me. I pick some leaves along the stem to be able to put it down deep at the retraining to a 4 liter roskruka.
I fill in with a layer of rosjord at the bottom of the pot and press to the easy then just putting down the plant in the pot and then fill in with soil. Now it looks really nice out or, more accurately, so it looks like I want it. I hoses carefully and put it under my fluorescent lamps, There will now be at it's time for the plants to come out.
You should not plant his Chiles to deep if it is not necessary when you can get rot on the trunk which is underground if it keeps the soil too moist so I let it dry out just in time before watering again.
PS. I have 5 St “Carolina Reaper Hot Pepper AKA HP22B” plants and it is only this that gets this treatment.
