Gardening Advice

General tasks and garden maintenance

Beware of 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 much later on in the month, and even then be prepared to cover it if necessary.

Deadhead daffodils and narcissi; give them a liquid feed or a sprinkling of bonemeal and then let them die down. Don’t cut off the leaves as they are necessary to replenish the bulb for next year. Keep deadheading spring bedding to keep it looking neat, and to encourage new flowers.

Continue with the spring cleaning. Hoe your borders, getting 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.

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 Use your own garden compost or leaf mould, well rotted manure, the contents of out-of-date grow bags or ready-made soil conditioner.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 fertiliser 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 fertiliser and replace the mulch.

Carry on removing moss and weeds from paths, terraces and drives.

Make new beds and borders - mark the shape with sand trickled from a bottle, remove the top layer of growing vegetation and dig the ground over, incorporating as much organic matter as possible. If you are making a bed in the lawn, remove the turf – if you dig it in the buried grass will regrow.

Clean and repair your garden tools, book the lawn mower in for a service and check garden furniture for any rot. When it is warm enough, treat sheds, fences and trellis with wood preservative; brushes and rollers are fine for most things, however a sprayer is well worth buying for tricky projects such as woven panels!

Now is the time to wage war on slugs and snails. They love tulips and delicacies such as the delicious young shoots of delphiniums and the like, so use pet-friendly slug pellets, and drench the ground around hostas with liquid slug killer to exterminate slugs below the surface. Keep an eye out for snails and pick them off - what you do with them is up to you. Birds are your friends here - flat stones artfully located are useful accessories for birds to practise their snail catching techniques.
