General Garden Maintenance

  • Feed pelargoniums and spray against rust where necessary.
    Lift and divide white arum lilies and irises after they have finished flowering.
  • Feed the lawn and mow regularly.
  • Fertilize roses and prune them lightly for lovely autumn blooms.
    Spray regularly against black spot and mildew.
  • Control ants, as they introduce aphids and scale to your plants.
    Make cuttings of azaleas, fuchsias, hibiscus, camellias and impatiens.
  • Finish planting nerine bulbs.
  • Annuals, Roses, and perennials like geraniums, daisy bushes and lavender need to be dead headed regularly to promote growth and encourage flowering. Phlox and catmint also respond well to deadheading. Remember to de-bud Dahlias at regular intervals.
  • Hedges, standards or “lollypops”, screens and topiaries need to be pruned regularly to keep them neat and in shape.
    • Fertilize and water PelargoniumsCannasGladiolus and Dahlia well and repeat feeding every second week or so.
    • Prune Acanthus mollis down to ground level and mulch well.
    • Check Dahlias and Hydrangeas for red spider mite.
    • Arum liliys, Irisis and Cannas can still be divided and re planted this month.
    • Tip and semi-hardwood cuttings can be made from the spring growth of Rhododendrons (Azalias) and Camellias.
    • Start watering Camellias well and mulch around but not against the stems.
    • Spray grapes for mildew if necessary.
    • Water Strawberries, Mulberries, Guavas, Pawpaws, and Citrus well.Ensure Chrysanthemums well supported and feed them every second week with a water soluble fertiliser.

          Watering

  • Water all trees well once a month during dry weather and trim any branches that have been broken by wind or hail.Continue to feed Annuals with a liquid fertilizer every second week.
  • Water the entire garden well during dry periods and pay special attention to the roses, water them nice and deep at least once a week. Keep your Agapanthus which are now in full bloom well watered for a really spectacular show.
  • To minimise your gardens water requirements:
    • Refrain from watering during mid-day.
    • Water thoroughly and deep at less frequent intervals rather than a quick splash on a more regular basis.
    • Though it is often tempting remember not to turn or “cultivate” the soil as this invites evaporation and stimulates weed seed germination.
    • Consider putting up a rain water tank this rain season, as a wide variety of vegetables and container grown plants give best results if watered with rainwater.
    • Keep the garden well mulched.

          Lawn

  • Mow bunch type and finer leaved lawns once a week, Kikuyu looks and performs best when mowed twice a week.

          Weeds

  • Remove weeds from the lawn by applying a broad-leaf weed-killer, weeds in the garden bed are best removed by hand before they flower and set seed.
  • Treat weeds in the driveway and paving with boiling water on a hot day, remove them by hand make use of a number of no- selective weed-killers available on the market. – avoid spraying on windy days and strictly follow dosage and package instructions.
  • Minimise weeds by applying mulch and weed guard or landscape fabric and refrain from turning or “cultivating” the soil.

        Pests & Disease

  • Spray regularly where necessary to keep the garden free of pests. – There are a number of organic products and remedies available.
  • Red spider mites love the hot dry weather so keep a close eye throughout the garden – they tend to gather on the undersides of foliage and can be treated with a spay of cold water when present in smaller numbers.
  • Keep an eye out for dollar spot on the lawn.
  • Mildew also tends to be a problem now (especially on Zinnias) spray if necessary
  • Amaryllis-borer caterpillar is a persistent problem on Clivias, Amaryllis, Zantedichia, Agapanthus and nerine so squish these black and yellow striped terrors on sight.
