Pull it out, remove all the soil from the roots, re-pot with fresh mix in a container
with drainage, and use a chopstick to work the mix into all the spaces between the roots.
Water the plant in, and then let the mix drain. Don't put the pepper back into direct sun or
intense light - it will need several days to recover. Keep it from moving around too much,
as well, so that the roots will re-establish themselves sooner. After approximately two weeks,
fertilize with a half-strength dose of fertilizer (such as Miracle Grow).
