Kalanchoe - potting questions

October 10, 2011 6:44 AM

When, if, and how should I repot my new kalanchoe?

I bought a kalanchoe about a week and a half ago. It's in the sunniest south-facing spot in the house (filtered sunlight) and I'm being careful not to water it too much. I'm in New England and indoor temps right now are 63-77 degrees - I don't have the heat on yet. I have forced-air heat which will dry things out considerably.

More flowers are opening by the day, and while I'm a little concerned about how some of the leaves look (brown edges/breakage on a few), I swear it's taller than it was when I bought it.

The poor plant looks cramped: it's in one of those little 4-inch green plastic pots. Should I repot, and if so, when? What size pot, and which growing medium (regular potting soil)?

If you ease the plant and its rootball out of the pot, can you see much soil, or just a mass of roots winding round and round? Kalanchoes flower better when they are fairly rootbound, so it's best not to re-pot until there's very little soil visible through the rootball.

I think with kalanchoes the best time to re-pot is when they're dormant. So Feb/March, before it starts to want to flower again.

Two tips I can offer. First, transplant up slowly. Succulents actually prefer to be rootbound, and if they're in too big a pot, they'll root out too far and get a little weaker.
Potting soil will be just fine. Basically, anything well-draining will work.

Response by poster: Thanks everyone. I'm glad I asked, since I was ready to do it now and it sounds like that would have been exactly the wrong thing to do.
