You can plant geum just a tiny bit earlier in the year because they are barely cold tolerant.

The last month that you can plant geum and expect a good harvest is probably August. You probably don't want to wait any later than that or else your geum may not have a chance to fully mature. If you are starting your geum indoors then you might be able to get away with starting them a little bit earlier.
