Gardening Tips for May


Watch out for late frosts, protect tender plants

  • Choose plants that are reliably hardy and suited to your growing conditions. Our in store gardeners will be happy to assist you!
  • Slightly tender plants should be grown in a warm sunny spot, e.g. against a south-facing wall, which will provide some extra warmth
  • If cold weather persists, cover plants with a double layer of horticultural fleece or other suitable protection when frost is forecast

Earth up Potatoes plant 

Earth-up the plants by drawing soil around the stems to form a ridge. The final height of the ridges should be 20-30cm (8in -1ft). Earthing-up will exclude light from tubers preventing them from going green – green tubers are potentially harmful if consumed

Plant out Summer bedding (at end of month)

Why not get creative with your designs? Do you dare give formal bedding a go? Most public gardens use formal bedding to create neat, symmetrical patterns. If you'd prefer to have some fun with colour and texture then informal bedding may be more your style! Straight lines are not compulsory, so why not try your hand at making your garden charming and unique!

Water early and late

Rainwater can be collected from the roofs of homes, garages, greenhouses and other garden structures as long as they have gutters and a drain pipe.

Regularly hoe off weeds

Open greenhouses to vent on warm days


Mow lawns weekly and apply fertiliser if you have not done so

Lift and divide overcrowded daffodils and spring bulbs

Tidy up climbers, apply fertiliser to composts

Plant up hanging baskets

Fill tubs and containers with bright Summer plants

Move houseplants away from strong sunlight to a shadier position.

Carrots, Turnips and Swede seedlings should be planted now to produce crops throughout Summer and Autumn.
