March is the busy month, the weather is beginning to warm up so plenty of sowing and even repotting.
General Garden
Finish deadheading, trim roses back a bit more.
Don’t forget to prune buddleia, hydrangea and wisteria.
Bulb plants such as dahlia and lilies can be planted.
Vegetable Planters
Plant early potatoes, onions and asparagus. Top off with slow release fertiliser. Plant carrots, turnips, beetroot under cloches.
Broad beans can be planted directly.
Place the cloche down over well watered drills prior to sowing. Remember to water weekly. Direct sow onions and replace cloche.
Mid-March – plant potatoes
Fruit Cage
Last chance to plant bare rooted fruit trees until November.
Good month for planting cane fruits (raspberries etc). Top off with fertiliser like fish, blood & bone.
Growing in the Greenhouse
Sow celery, aubergines, courgettes, leeks, lettuce, radish, parsnips, spinach, beetroot, turnips, tomatoes and cucumbers for planting out once all danger of frost has passed.
Most herb plants can be started now.
Sow wildflower seeds in trays.
Harvest
Remove the last of the leeks and parsnips now. Also the last of the late brussels sprouts, cauliflower and swedes.
