Paraic’s Tips For Your Garden in Late August

Late August is a time in the garden when you enjoy this year’s harvest but also start to plan for next year’s spring growth. Although the tasks are less numerous, there are still a few jobs that need to be done at this time.

This is an excellent time to take semi-ripe cuttings from your favourite shrubs such as Ceanothus, Choisya, Viburnum, Lavender or Rosemary.

  1. As the name suggests, you should select a new, yet sturdy, side shoot (non flowering) and remove it by cutting straight across just below a leaf joint.
  2. Remove all the leaves from the cutting apart from the top set.
  3. Dip the freshly cut stem into Strike Rooting Powder and insert the cuttings around the edge of a pout filled with a suitable compost such as GroWise Seed and Cutting Compost. If you don’t have access to specific seed compost, use a mix of one part regular compost to one part Gro-Sure Perlite.
  4. Firm the cuttings and compost gently and water well.
  5. The pot should be over-wintered in a cool bright area, such as a cold frame, and the cuttings should be rooted by spring.
  6. Your young plants can then be grown on in a relatively shady area of the garden and should be ready for planting out in early summer.

One of the jobs in late August is preparation for Spring; the new selection of Spring bulbs will begin to appear in your local garden centres. Think back to late May when you noted gaps to be filled and buy accordingly. Daffodils, Crocus and Snowdrops should be planted from now to the end of September but Tulips are best planted as late as October or early November.
pruning roses
Those with a rambling rose should consider pruning it after flowering by removing approximately one third of the oldest stems. The younger stems should be tied in securely after shortening them by approximately two thirds.

Summer flowering shrubs like Lavender and Hebe should be clipped at this time to remove the spent flowers. This serves many functions, but most importantly it will help to maintain a good shape to the plant and it will stop the formation of leggy growth. Remember, don’t clip them back too hard into the old wood.

Another area of preparation in the garden in August are the greenhouse, sheds and hard surfaces. Any repairs should be undertaken now before the onset of the autumn rains.

Don’t forget to keep the patio and hard surface areas of the garden moss and algae free as theses will be slippery during the wet Autumn and Winter weather. Try using PAC Patio Algae & Moss Cleaner; its long lasting formula will keep the area free of moss and algae for months.
