Tasks for December

Wash and store seed trays and pots ready for next year.

Keep off the grass when frosty or wet.

Now is a good time to prune back roses that are likely to be affected by the wind.

Keep an eye on the weather and keep greenhouse heaters on when the temperature dips.

Lift and store dahlias and cannas once the foliage has been frosted.
(You can lift half from each clump and cover the remaining tubers with leafmould. This will give a longer flowering season next year).

Rake up fallen leaves and store them in a pile to rot down into leafmould.
