When to plant sweet corn in Gilberton
- Sow in the ground: late Aug to mid MarGilberton area, hot semi-arid
Worked out from 30 years of climate records for Gilberton. 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.
