Autumn in the Garden
January is a month of rapid growth and the heat can continue well into February. Water regularly and thoroughly to keep plants growing but remember to observe local water restrictions. A good layer of mulch will help to conserve water and provide humus to your soil.

Dahlia, Dianthus, Dwarf Geranium, Impatiens, Lobelia, Marigold, Nasturtium, Nicotania, Penstemon, Petunia, Phlox, Portulaca, Snapdragon Salvia, Verbena, Vinca and Zinnia

Mulching and Watering
Now is the time to mulch your gardens to keep your plant roots cooler, to reduce evaporation and to help prevent weed growth. If you find that water runs off the soil rather than soaking in, then a product like Wettasoil or Saturaid will assist with water penetration through to the roots.
Pruning
- Cut Callistemons back to behind the flowers as they finish blooming
- Prune spring flowering shrubs
- Dead head annuals weekly
- Trim perennials such as penstemon, salvia, marguerite, daisies etc to promote further flowering
- Prune pelargoniums and geraniums
- Dead head roses weekly, and give a light prune in February for a good autumn display
- Trim back climbers once they have finished flowering
- Cut back lavenders once flowering has finished
Trees shrubs and climbers
