Repotting lobelia

Question

When is the best time of year to repot my lobelia, please!

Answer 1

It's not so much a question of the time of year to re-pot but conditions that warrant a re-potting. Re-pot if your lobelia is root bound, outgrows its pot or when the water doesn't quickly drain. Trim back the roots and the top of a plant and repot in the same container (or the next larger size) with some fresh potting soil.
