28 Jun 20, Judi (New Zealand - temperate climate): My 6-yr-old came home with an egg carton of sweetcorn seeds he'd planted at school. We put them on the windowsill and they've sprouted beautifully. But it's June, and although it's very mild now (in Waikato) we're expecting to get winter weather soon. He's very excited about these seedlings and would love to grow them to fruition - do you think I could grow them in a large pot as an indoor plant?

30 Jun 20, Anonymous (New Zealand - temperate climate): Corn needs to be planted in rows about 6-800mm apart. Seeds need to be planted about 150mm apart. Best to grow 2 or more rows together in a block for pollination. When the tassel and silks come out it takes about 5 days for pollination. Then about 21 days for cob to be ready to pick. Read up on the net.

Replying to:

Plant 2-3-4 rows about 80-90cm between rows. When plants are about 40-50cm high run some fertiliser down each side of the plant and then hill the soil up around the plants. Makes the plant more stable in the ground.
