I would like to know more about these two items you have (if you don’t mind my askinig)...
05906 - Ripple Mix Horizon Hybrid Geranium
05243 - Rose W/Bronze Leaf Big Hybrid Begonia
Both are an expensive way to get a few flowers, LOL! How’s that?
If you’re in a Zone warmer than I am (4/5) I’m not sure of when your starting times for those seeds would be. We start Geranium and begonia from seed/tubers in January up here.
Geranium seed is not very reliable, and they’re expensive. I have a local guy grow all of the geraniums we sell from cutting stock; even Jung’s doesn’t grow out geranium or begonia from seed; it’s cheaper to bring it to the public via plant cuttings.
Not to discourage you; you just picked two varieties that are hard to grow from seed. It CAN be done, though, or else people would stop buying them, right? ;)
