Why have my chilli seedlings stopped growing?

I'd say the stress of replanting is causing this non-growth. Small damages to roots and new type of soil. The seedlings need to recover. I'd be patient.

What's the fastest way to dry peat before re-potting an overwatered succulent?

Well I wouldn't worry about drying it out first - simply tip it out of its pot, preferably wearing gloves, carefully, and with any luck, most of the wet soil will fall off immediately anyway. The ...

Why should a pot be only an inch or two bigger than the previous pot when re-potting?

Roots head for moisture not walls. If you want a plant with deep roots, you water deeply and allow to dry before watering again. This trains the roots to grow towards the water so it will have the ...

Should I repot my plants that I bought online?

These are good sized, healthy plants, and the pots aren't tiny either. The fern and the Ivy should be potted on into something larger, not least because the soil level is too high in the pot - it ...

Do succulents need to be kept out of the pot for some time before re-potting?

The rationale is simply to allay as much chance for rot as possible. Succulents in particular are susceptible to rot and newly-broken roots from them, especially so. Also, it's purported that the dry ...
