I've been growing habaneros for about a month for the first time and learning on the go and I think the soil they're currently in is too heavy/tightly packed (there's a empty space all around the edge of the container). I've found a better soil and was thinking on repotting them with the new soil but don't know if I should remove the old soil completely or just take the plant with the soil and pot up filling the empty space with the new soil. Should I do it without removing the soil to avoid disturbing the roots?
