Timing matters a lot with pruning, and getting it wrong can cost you a season of flowers, fruit, or just leave a plant looking hacked about for months. Late winter through early spring is a genuinely important pruning window for a lot of Blue Mountains gardens, so here’s what’s worth tackling before everything bursts into new growth.
Deciduous fruit trees. Apples, pears, plums and similar fruit trees are best pruned while still dormant, ideally before buds start swelling. A good structural prune now — removing crossing branches, opening up the centre for airflow, and taking out any dead or diseased wood — sets the tree up for a better crop and makes the coming season’s growth much easier to manage. Miss this window and you’ll be pruning into active growth, which is harder on the tree and costs you fruiting wood.
Roses. Late winter to very early spring is prime rose pruning time across the mountains. Cutting back hard now — removing weak, damaged or crossing growth and shaping the plant — encourages strong new growth and a better flush of flowers through spring and summer. Leave it too late and you’ll be cutting off flower buds that have already formed.
Winter and early-spring flowering shrubs — prune after flowering, not before. This one trips a lot of people up. Plants like camellias and some early-flowering natives set their flower buds on the previous season’s growth, so pruning them hard right now can mean cutting off flowers that haven’t opened yet. The rule of thumb is to prune spring-flowering shrubs once they’ve finished flowering, not before.
Hedges. Early spring is a good time to give hedges a solid shape-up before the main flush of spring growth kicks in, particularly if they got away from you a bit last year. A tidy now makes it much easier to keep on top of regular trims through the growing season rather than constantly chasing overgrowth.
Deciduous ornamentals and shade trees. Trees like Japanese maples, liquidambars and ornamental pears are generally best pruned while dormant, for the same reasons as fruit trees — it’s easier on the tree and easier to see the structure without leaves in the way. Once they leaf up, larger structural cuts become more stressful for the tree and messier to manage.
What not to prune right now. Anything that flowers on new spring growth — many roses aside — can often wait, and frost-tender plants are best left alone until the risk of frost has properly passed, since fresh pruning cuts and new growth are more vulnerable to cold damage.
Storm and frost damage should be dealt with regardless of season. Broken, dead or hazardous branches don’t need to wait for the “right” pruning window — get those removed as soon as you spot them, particularly anything near the house, fence lines or power lines.
Getting pruning timing right across a whole garden takes a bit of species knowledge, and getting it wrong can set plants back a full season. If you’d rather leave it to people who deal with this across the mountains every week, our tree pruning and hedge trimming services are exactly for this.
