Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Dublin you can estimate when it's possible to plant geum by checking out the USDA zone info.

Frost tolerance for geum:	Tolerant of a very small amount of frost.
When to plant:	Up to 3 weeks before last frost.

Since geum are one of those plants that can tolerate a tiny bit of cold weather you can plant them a bit earlier in the year than other frost tender plants.

The earliest that you can plant geum in Dublin is March. However, you really should wait until April if you don't want to take any chances.

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 couple of weeks earlier.
