Buying new plants during the bank holiday? Why not buy plants that will benefit local wildlife?

Trees, shrubs and climbers

- Tie climbing and rambling roses as near to horizontal as possible to restrict sap flow thus causing more sideshoots to grow along the stem resulting in more flowers.
- Mulching rose and shrub beds with a layer of organic matter will help retain moisture and reduce weed build-up; even improving soil structure over time.
- Delay pruning any spring-flowering shrubs such as Forsythia until after they have finished flowering or this year's display will be lost.
- You can still plant deciduous hedging plants, shrubs, trees and climbers.
- Prune evergreen shrubs such as Choisya ternata and evergreen Ceanothus.
- Remove frost damaged shoots from evergreens damaged by wintry weather.
- Remove green shoots on hardy variegated evergreens that are reverting to a single colour.
- Take cuttings of conifers for propagation of your favourites.

Lawn Care

- Mow lawns - the aim is to maintain a constant height; not necessarily short! Do what is best for your lawn.
- Cut the lawn edges and create a 3in gutting between the lawn and flower borders.
- You can sow new lawns or over-seed dead patches from mid-April to early May.
- Apply a high nitrogen spring lawn fertiliser to encourage good, strong growth.
- If you have a problem with moss you can choose a combined fertiliser and mosskiller when feeding the lawn but beware that moss killer can stain clothes.
- April is the best month to apply lawn weedkillers as the weeds are inactive growth.

Pond Care

- Pond algae grows when there is excessive sun light. Create extra shade by dividing and replanting waterlilies when they are showing signs of growth.
- Start feeding the fish.
- Clean out your pond filter. Check the filter a week after cleaning it as the water will be very dirty from the winter and it may need cleaning again.

Flowers

- Deadhead spring bedding plants such as pansies and primulas.
- Remove tired or dead winter bedding and plants that did not survive the winter.
- Divide any herbaceous perennials you want to propagate.
- Put supports in place now for perennials so that they can grow over them.
- Sweet peas can be sown outside this month.
- Prune penstemons, Teucrium, lavender and other slightly tender plants making the cuts just above fresh, new shoots.
- Plant summer-flowering bulbs.
- Deadhead daffodil and tulip flowers, nipping off the heads and seed pod as they fade but don't cut them down yet.

Greenhouse and house plants

- Indoor/conservatory plants will need more watering as the days get longer.
- Hydrangeas and fuchsias can be propagated from softwood cuttings from the stem.

Soft Landscaping

- Remove algae from paths using a brush with stiff bristles or a pressure washer.
- If the weather is dry paint wooden fences, sheds etc with a wood preservative. Ensure that you use only new chemicals as some older brands are now illegal.
- Think about any soft landscaping you would like done now to enjoy during the summer; decking for example.
