One of the best tools that you have as gardeners to help us figure out your gardening schedule is the USDA zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Glasgow you can estimate when it's possible to plant aubretia by looking at the USDA zone info.

Since aubretia do well in cold you can plant them quite a bit earlier in the year than more sensitive plants.

The last month that you can plant aubretia and expect a good harvest is probably September. Any later than that and your aubretia may not have a chance to fully mature. You can get started a little bit earlier by starting your aubretia indoors.
