- Deadhead flowering plants.
- Plant summer-flowering annuals.
- Feed citrus and litchi trees.
Feed and Fertilize
- Reduce feeding throughout the garden during June and the cooler months ahead.
- Feed winter-flowering annuals every 14 days with a water-soluble fertilizer like Nitrosol or Multifeed.
- Keep your spring-flowering bulbs moist at all times and feed them with bulb food for best results.
Mulch
If you didn’t make use of mulch during the hotter months, you have no excuse now as mulching will prevent the soil from losing moisture on hot days in the warmer regions. Mulch will also help with protection on cold frosty nights in the colder regions and serve a dual purpose for our more temperate regions! In case you needed yet another reason to get stuck in, mulch is also great for suppressing weed growth.
