01Bush habit, big appetite

Unlike sprawling pumpkin vines, zucchini grows as a compact bush — but it's still a heavy feeder needing rich soil and steady water to keep producing.

02Planting

Method
Sow or plant seedlings into a rich mound.
Soil
Rich, well-drained — dig in aged compost before planting.
Timing
Plant after frost risk passes and soil has warmed.

Planting timing varies significantly by Australian climate zone. Set your zone above (or use the Find My Climate Zone tool) for guidance tailored to your own area.

03Growing care

  • Water deeply at the base, avoiding wet leaves.
  • Pick young and often — one missed fruit can slow the whole plant down.
  • Feed every few weeks through the growing season.
  • Hand-pollinate if fruit are forming but rotting at the tip (poor pollination).

04Problems

  • Powdery mildew — white coating in humid weather; improve airflow.
  • Blossom end rot — irregular watering; keep moisture consistent.
  • Vine borer — sudden wilt; check stem base.
  • Poor fruit set — low bee activity; hand-pollinate with a soft brush.

05Harvest & storage

Signs
Fruit reaches 15–20cm — pick young for best flavour and texture.
Method
Cut with a sharp knife, leaving a short stem.
Curing
None needed.
Storage
Fridge crisper, about a week.
Preserving
See Fermenting (fermented pickles) or Root Cellaring (storing winter squash and pumpkin) for ways to keep a harvest surplus.
