Hilltops Growing Conditions
Soil, climate and a planting calendar for Hilltops — across 9 postcodes.
Soil
The soil most gardeners hope for: a balanced, free-draining loam that holds moisture without waterlogging and suits almost everything — lawns, vegetables, natives and ornamentals alike. It asks little beyond an annual mulch to keep its structure. A clay-loam subsoil beneath drains moderately and holds a useful reserve of moisture into summer, though low spots can still sit wet after heavy rain.
Climate & hardiness
A cool-climate area — ANBG Zone 1 — with the coldest nights in the country, down near -3°C, and real frosts through winter. Choose frost-hardy and cool-climate plants, hold tender crops until the frosts clear, and shelter young growth from cold winds.
Rainfall & growing season
Low rainfall (617mm a year) — established beds still need summer watering, and drought-tolerant and native plantings suit the climate best. A long, largely frost-free season (~352 frost-free days), with only light frost risk at the margins of winter.
Watering & drainage
This soil holds only a modest reserve of water for plants (about 102mm), so it dries between rains — mulch heavily, improve it with compost, and water little and often through summer.
Planting Calendar for Hilltops
