fertilizing my geranium plant

Asked October 31, 2017, 3:12 PM EDT

Trimmed back about 1/2 of geranium plant I brought in--when do I start fertilizing it again so it will be nice by May? March or April?

I'm assuming you want to keep the geraniums inside as a houseplant over winter - there are other ways to keep geraniums into the next season, described in the references below. If that's the case, the ideal growing conditions may be challenging: bright light but not too warm (60's). Fertilize once a month with a typical houseplant fertilizer at 1/2 rate. Don't overwater. Then in late March or early April, start fertilizing more regularly and at full concentration. But don't expect blooms until May or June.
