Beware treacherous late frosts and keep vulnerable plants and new shoots protected at night if frost is forecast. Don’t be tempted to put out tender bedding until the middle of the month and even then be prepared to cover it if necessary.

Continue with the spring cleaning. Hoe your borders to get rid of weeds before they take hold - annual weeds such as bitter cress and groundsel are enough of a nightmare without allowing them to go forth and multiply by seeding. If it’s dry, attack ground elder and the like with systemic weed killer painted onto the leaves. Remember these systemic weed killers are indiscriminate and will kill anything they contact. Dandelions are a monstrous nuisance at this time of year - if you don’t have time to deal with them terminally, at least chop their heads off before they set seed.

Mulch away while you can still see what you are doing and before the herbaceous growth really takes off. Use your own garden compost or leaf mold, well rotted manure, the contents of out-of-date grow bags or ready-made soil conditioner.

Now the soil is warming up and things are starting to grow, add general purpose fertilizer before covering with mulch especially in borders, the fruit and vegetable patch and containers. If you have already mulched, draw it back (if possible), tease the soil a little, add fertilizer and replace the mulch.
