Preparing Your Cape Town Garden for Summer

/in /by

As the days grow longer and the Cape Doctor winds start to pick up, preparing your garden for the hotter, drier summer months is crucial for its survival and beauty. With 25 years of experience maintaining gardens across Cape Town’s Southern Suburbs and City Bowl, Garden Greening knows exactly what your plants need to thrive.

Follow this essential checklist to ensure your outdoor space remains a vibrant oasis throughout the summer.

1. Water Wisely: Efficiency is Key

Cape Town’s summers are famously dry, making water conservation paramount.

  • Audit Your Irrigation: Now is the time to check your irrigation system. Look for leaks, broken sprayers, or blocked drippers. Ensure heads are positioned correctly to water plants, not pathways.
  • Water Deeply, Less Frequently: Encourage deeper root growth by watering thoroughly two to three times a week rather than light daily sprinkles. This helps plants become more drought-resistant.
  • Best Time to Water: Water in the early morning (before 9 AM) or late evening (after 5 PM) to minimise evaporation.

2. Mulch, Mulch, Mulch: Your Garden’s Best Friend

Mulching is perhaps the single most effective task you can do to help your garden through summer.

  • Apply a Thick Layer: Spread a 5-10cm layer of organic mulch (like bark chips, compost, or straw) around your plants, keeping it a few centimetres away from stems and trunks.
  • Benefits:
    • Retains Moisture: Significantly reduces water evaporation from the soil.
    • Suppresses Weeds: Less competition for water and nutrients.
    • Regulates Soil Temperature: Keeps roots cooler in the scorching heat.
    • Enriches Soil: As organic mulch breaks down, it adds valuable nutrients.

3. Pruning for Health and Bloom

Strategic pruning now can improve your plants’ summer performance.

  • Remove Spent Blooms: Deadhead flowering plants to encourage more blooms throughout the season.
  • Light Shaping: Lightly prune shrubs to remove any dead or weak branches, improving air circulation. Avoid heavy pruning of summer-flowering plants that are about to burst into bloom.
  • Consider Shading: For very delicate plants, consider temporary shade cloth if they receive intense afternoon sun.

4. Feed Your Plants (But Not Too Much)

Summer growth can deplete soil nutrients, but a balanced approach is needed.

  • Boost with Compost: Top-dress beds with a layer of good quality compost to provide a slow release of nutrients and improve soil structure.
  • Consider a Balanced Fertiliser: If your plants look a little lacklustre, a balanced, slow-release granular fertiliser can provide the necessary boost without risking burn in the heat. Always water well after applying.

5. Get Ahead of Pests and Weeds

Summer can bring increased pest activity and rapid weed growth.

  • Regular Checks: Inspect your plants weekly for signs of common summer pests like aphids, red spider mites, or whitefly. Early detection is key to natural or minimal intervention.
  • Weed Consistently: Remove weeds before they have a chance to set seed and before they compete with your desirable plants for precious water.
