It’s the month of July, and Midwinter has arrived! As all of Nature’s energies turn inwards, and life comes to a standstill, we finally have a chance to rest and reflect too.
During this month temperatures will hit their lowest for the year in many parts of Australia. It’s the coolest and driest month for Darwin. Weather is mild and sunny in the Northern Territory with no rain at all, and days are warm in Queensland. Brief spells of strong winds may be experienced, which increase bushfire risks in the north.
There’s a range of seeds to sow, and lots of opportunity for winter pruning, relocating deciduous plants and planting new ones!
Things to Do This Month:
- Divide existing perennials and plant new perennials.
- Install windbreaks, such as the plastic tree guard sleeves, around newly planted evergreens.
- Prune tall shrubs to reduce height to better resist winter winds.
- Relocate any deciduous plants (trees, shrubs, vines) or herbaceous perennial plants growing in the wrong place in winter.
- Collect and sow seeds from berry producing trees and shrubs.
- Some perennials can be propagated from root cuttings, which can be taken through winter.
- Continue propagation of hardwood cuttings which began in autumn – prune off 30cm long shoots of current season’s growth, cut off the soft growing tip, cut off the bottom end below a bud, and dip end into rooting hormone. Make a ‘slit trench’ by pushing a spade into soil and rocking it back and forth. In clay soil, add some coarse sand for drainage. Put cuttings in so 2/3 is below the soil, and press the soil down around them. Cuttings will root and be ready to plant next autumn.
- Continue planting shallot bulbs.
