TO DO INYOUR GARDEN NOW…
TREES, SHRUBS AND ROSES
CONTINUE the planting of evergreens and prepare the ground for deciduous bare-root trees next month. Most shelter belts and small woodlands are planted with small plants, called whips or transplants. This is most cost-effective and the trees establish better from small plants. Good weed control is essential. Check that staked trees are firmly tied and the stem is not rubbing against the stake. Shrub borders can have the residual weedkiller simazine applied, if not already done, but existing weeds must be controlled with Roundup or Gramoxone if there are perennial weeds present. Climbing roses can be pruned if fully flowered.
GREENHOUSE AND HOUSE PLANTS
MOST of the greenhouse crops can be cleared out soon, such as tomatoes, chillies, melons and cucumbers. Throw out any old plants that are past their best or half-dead plants because they are a source of pests and diseases. Tidy up all debris and reduce watering to just enough to keep pots from going dry. Place rooted cuttings in a bright position and also winterflowering plants such as Christmas azaleas and Christmas cactii.
FLOWERS
HERBACEOUS perennials that have grown too wide can be lifted and divided over the coming weeks, but not grasses. Try to resist the urge to propagate some of these rampageous plants for plant sales and the like. You are not doing any favours for other gardeners and it is not a waste to cover these troublesome plants/ weeds if they are going to become an even greater problem along the river banks. Usually summer bedding can be removed in preparation for planting spring bedding. This is the main time for planting spring bulbs and containers for spring colour.
