One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In London you can determine when to plant bellis by referring to the USDA zone info.

Bellis are one of those plants that can tolerate a little bit of cold weather which tells us that you can plant them a little bit earlier than more sensitive plants.

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

The last month that you can plant bellis and expect a good harvest is probably September. If you wait any later than that and your bellis may not have a chance to fully mature. If you are starting your bellis indoors then you might be able to get away with starting them a couple of weeks earlier.
