When planting very small seedlings protect them with some shade for 5-7 days. Transplant seedlings when they are 75-100mm high. Seasol is not fertiliser, it is a soil conditioner. Go and buy some fertiliser (organic or chemical). Wait until the plants have grown to 150mm high then fert lightly. Do again a month later, this time use more fertiliser - read the instructions. Buy a 2-3 kg packet of fert. The little tubs of fert are a rip off. When growing corn plant 2-3-4 rows 600mm apart for pollination reasons. Corn needs lots of fert and water.

Can you tell me what the best variety of sweet corn is for the tropics, and is it too late in the year to plant it here (Darwin NT)? It is currently our Dry Season - ie no rain at all. Thank you.

I have just bought seeds from Eden seeds for Bali corn, which is suited to tropics and will give two cobs per plant. I haven't planted yet, tho that is why I'm looking a t comments for any hints.

You can plant it any month except Dec. Try Sweet Corn Bi- Colour from BOONDIE SEEDS on the internet. I usually buy several packets at a time. Plant several rows 2.5' apart. When plants are 18 (?)

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.
