Your new lawn is ready to be sown if you did the preparation last month. Time to exercise those muscles with some digging, rotovating and working manure into the borders. There are spring bulbs to be planted and seeds to be collected.
Many seeds will keep happily in brown envelopes somewhere dry and cool, for sowing next year. Time to tidy up and hoe out weeds, stake dahlias and take cuttings. There are plenty of tender perennials that, having been grown as summer annuals, all too often get dug up and consigned to the compost heap. Marguerites, osteospermums, fuchsias, pelargoniums to name a few can provide cuttings which can be potted, put into a cold frame to harden off and then brought indoors before the first frosts. Kept inside through the winter you can have young plants next spring to plant out in May to June.
