August gardening jobs
- Wake plants from their winter slumber with a pre-spring fertilising campaign with slow-release fertiliser or pelletissed manure.
- Check for citrus gall wasp (indicated by ugly swelling on stems), remove with a knife if needed and destroy to stop new infestations.
- Prep to plant a hedge in early spring by turning over soil for aeration and nutrients.
- Sow seeds for early tomatoes (in colder areas sow in a tray on a sill indoors).
- Fertilise lawns towards the end of August as part of their winter recovery.
- Feed jonquils and daffodils as they finish flowering, but don't cut back foliage until fully dead.
- Lightly prune camellias after they have finished flowering.
- Inspect azaleas for petal blight and spray if necessary.
- Finish pruning your roses by mid-August and spray for black-spot if it's been a problem in the past.
- Check out some of the striking wattles now in flower and make choices for your own garden.
