- Prepare for early vegetable crops by warming soil before sowing, covering seedbeds with polythene or cloches.
- Keep off wet soils to avoid compaction. Use long boards as walkways, to spread your weight.
- If the soil isn’t too wet, start to dig in overwintered green manures such as grazing rye and winter tares, as the frost should have killed them off.
- Continue to tidy up and re-cut grass path edges where the grass has encroached on your plot.
- Give your compost heap a ‘spring turn’ this month. Turning will aerate and stimulate the heap. If it’s too dry, continue adding wet kitchen waste, and water it occasionally. If too wet, add more carbon-rich stuff such as twigs, crumpled cardboard and paper waste, to open up and aerate the heap. Continue to add layers of uncomposted stable manure to your heap.
- Empty compost heaps when ready and spread the well-rotted dark crumbly compost on beds prior to sowing or use as seed compost.
- Chit potato tubers in a light, cool, frost- free place.
- Clean pots and trays by scrubbing in hot, soapy water before starting to sow new seeds. Pests and diseases can overwinter in old potting compost, surviving to damage newly emerging seedlings.
- Sow sweet peas in deep pots or Root-trainers in a cold frame, greenhouse or windowsill. (A wide range of sweet peas – single varieties such as King’s High Scent and Midnight as well as mixes e.g. Mammoth mixed and Incense are all available in store.
