Regularly water newly planted plants, young veg and container plants.
Apply and renew mulches to reduce water loss and suppress weeds.
Fill gaps in borders with summer bedding to give instant colour to otherwise bare patches.
Perk up your lawn by applying a feed using a liquid fertiliser.
Thin out aquatic plants and generally tidy up the pond before summer.
Prune mature, deciduous shrubs including philadelphus, deutzia and kolkwitzia, once they have finished flowering.
Remove faded blooms from rhododendrons and camellias, so allowing the plant’s energy to focus on building up buds for next year’s flowers.
Cut down overgrown lilacs, sawing them down to around 45cm (18in) from the base. A mass of new shoots will regrow and eventually lead to a bushier, better-shaped shrub.
Remove suckers from roses, identifiable because the foliage is usually lighter in colour. The suckers should be pulled off the plant at their point of origin on the roots rather than cut off.
Remove old leaves and flower stems from hellebores, which start to look tatty once they are over.
Cut down the foliage of bulbs naturalised in grass, if at least six weeks have elapsed since flowering.
Plant out cannas and lily bulbs, which were potted up when it was too cold to plant outside. They can now be planted in borders.
