One of the best tools that you have as gardeners to help us figure out 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.

The earliest that you can plant anise in London should be figured out by reviewing the USDA zone info.

When to plant:	Up to 3 weeks before last frost.

You can plant anise just a tiny bit earlier in the year because they do ok in moderate cold.

The earliest that you can plant anise in London 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 anise and expect a good harvest is probably August. You probably don't want to wait any later than that or else your anise may not have a chance to really do well. Starting your anise indoors is a great way to get them started a few weeks earlier.

Last Frost Date

On average the last frost when the weather gets warmer is on April 15 in London. It might get as low as -5°F during the coldest months of winter.

Since the USDA zone info for London is not always accurate the actual date of last frost is different every year. Half of the time in London it frosts late in the year after April 15 so be sure to be ready to protect your anise if you have a surprise late frost.
