Gardening Advice For May


Probably the busiest month of the gardening calendar, when most of us plant out tender bedding plants, summer seeds and vegetable plants such as beans and tomatoes. Established roses, shrubs and herbaceous plants will soon be in bloom and weeds will be running riot in any bare patch of soil. It’s difficult to keep on top of everything, so here are a few guidelines for the most important jobs.
Take care to protect your bedding plants from frosts. Even when the days can seem warm night time temperatures can drop below freezing – so if you have planted out soft bedding remember to cover them with fleece at night.
Don’t forget to protect soft fruit such as currants and gooseberries from bird damage. Cover the plants with garden netting.
Watch out for aphids (greenfly and blackfly) on roses, delphiniums, lupins, foxgloves and pansies. They can multiply with phenomenal speed, so a weekly check throughout the garden is a good idea.
Plant up hanging baskets, patio pots with tender flowers such as fuchsias, geraniums, pelargoniums, busy lizzies, petunias and all manner of trailing plants such as begonia, lobelia, helichrysum and verbena. For magnificent results plant in Britain’s best container compost-Miracle-Gro Moisture Control Compost. This unique Aquacoir formula stores and releases water when the plants need it.
Nows the time to be earthing up your potatoes . When the plants have reached 20-30cm (8-12inches) tall then you need to draw the soil up and around them by scooping it out between the rows and using this soil to almost cover them over. This encourages potatoes to form higher up and ensures that light does not reach the developing tubers and turn them green. Ideally they should be ‘earthed up’ again in about 3 weeks.
