First, the good gardening news: UK sunrise should be 50 minutes earlier by the end of the month. Sunset almost an hour later, days nudging two hours longer by 28 February.
Now, though, the weather. Temperatures can be fierce. They’re often lower than January with severe frosts, sometimes snow. So don’t rush to sow outside even on a bright sunny day. In contrast to TS Eliot, I find February to be the cruellest month. Less so April.
