When the plants are 40cm high run a thin line of fertiliser down each side of the plants and then hill the soil up around the plants. This will give the plant better anchorage to the ground and produce a good strong plant.

Plant 20cm apart rows 60-70cm apart. 15-20 seeds in 2-3 rows Try Boondie seeds on the internet – variety “bicolour” nice and sweet.

Thanks everyone for the advise. WIll check out Boondie seeds! Also found Greenpatch seeds around the corner from them too. Looks promising.

Better to plant 2-3-4 rows to have better pollination.

Corn missing kernels: I believe this has to do with uneven pollination. Hand pollination could help. Corn stalk shade: My cats have discovered the best patch in the garden is under the corn stalks. Intercropping with corn: Second word on shade, last year i tried intercropping corn with beans, but it was a big flop for the beans: they grew but didn't produce any beans. The nitrogen along their roots may have helped the corn though as the corn grew brilliantly. This year i will experiment with another intercrop and space the corn more broadly--perhaps a leafy veg. Hot weather: Man, it's hot. Last year I harvested my corn after a spate of very hot weather and some of the kernels had started to shrivel. The taste was also clearly past prime compared to corn harvested just before the heat. Won't be doing that again.
