When to plant sweet corn in Canberra
- Sow in the ground: early Jan to early JanCanberra area, temperate oceanic
Worked out from 30 years of climate records for Canberra. Microclimates vary: frost hollows and hills run later.
A summer crop that needs warm soil, full sun and plenty of water. Plant in blocks of at least 4 by 4 rather than one long row, because corn is wind-pollinated and patchy pollination gives gappy cobs. Pick cobs when the silks turn brown and the kernels squirt milky juice.
