What to do in the garden in December
- Mow and apply a hose-on fertiliser to have your lawns looking their festive best for the Christmas and New Year celebrations.
- Give outdoor furniture a pre-Christmas clean with a pressure hose.
- Deadhead roses, cut away dead and ugly growth from bushes and lightly prune native plants.
- Add water-storing crystals to pots to keep your plants hydrated while you're much more busy celebrating than worrying about watering.
- Mulch garden beds and check that already-laid mulch has not formed impenetrable barriers.
- Cut back herbs that have gone to seed.
- Net fruit trees to protect summer crops from bird and possum attack.
- Dead spent flowers of annuals, and lightly trim and feed with liquid fertiliser to encourage vigorous new growth.
- Lay snail bait around vegie beds.
