Shoalhaven Growing Conditions
Soil, climate and a planting calendar for Shoalhaven — across 5 postcodes.
Soil
A soft, fertile silty loam that holds moisture and nutrients well and grows strong, lush plantings. It can cap or crust after heavy rain and compacts if worked wet, so add organic matter and avoid digging it saturated. A silty-clay-loam subsoil beneath holds moisture well but drains slowly, so raised beds and good falls pay off on wetter ground.
Climate & hardiness
A cool-temperate area — ANBG Zone 2 — with winter lows near 2°C and light to moderate frost. Most temperate garden plants thrive; keep frost-tender subtropicals to a warm, sheltered spot or grow them under cover.
Rainfall & growing season
A wet climate (1032mm a year): plants rarely go thirsty, but lean on free-draining soil, disease-resistant varieties and falls that shed water off paving and lawns. A frost-free, year-round growing season (~365 frost-free days) — something can be planted or harvested in every month, with warmth (and in the north, the wet season) setting the rhythm rather than cold.
Watering & drainage
This soil holds a generous reserve of water for plants (about 149mm), staying moist between rains — deep, less frequent watering suits it and drainage matters more than irrigation.
Planting Calendar for Shoalhaven
In the tropics and subtropics, the cooler, drier autumn–winter months are the easiest time to plant and establish new gardens.
Southern-Hemisphere timings, guided by this area's ~365 frost-free days and ANBG Zone 2; adjust for a cold or exposed garden.
