Maize is generally the term for corn that is high in starch. Corn for boiling bbq etc is sweet corn or super sweet corn. Buy it at a supermarket or garden markets when in season. I grow sweet corn a lot of the year.

Please what are the requirements for growing sweet corn in the tropics

The biggest problem with growing sweet corn is germinating the seed. The ground should be moist when planting the seeds. Give a light watering after planting. Don't water again for 3-5 days depend on how hot it is. If the soil is too wet the seeds will just rot. If really hot weather try and cover with shade cloth or protect them from the hot part of the day. Once they are growing plenty of fertiliser and water.

Always plant at least 3 seeds in each spot as I find they don't always germinate. It's good to have back up.

1. How do you know when Corn is ready to harvest? @ How many cobs can you expect from just one plant ( i have six plants which are pretty near harvesting - I think they seem to have 2 - 3 cobbs per plant?

When the tassel (the flowery part that comes out the top of the plant) comes out the top, pollination will take place for the next 4-6 days. A rule of thumb is 21 days after pollination. The silky threads at the top of the cob will turn brown and then black. After they have turned brown feel the cob with your hand. It should feel bulked up (thickish). Peel a little of the husk down the cob to see the kernels, if small and pale in colour, not ready yet. If nice kernels and good yellow colour right to pick. If the kernels are looking sunken and dry it is too late. Generally 1-2 cobs per plant. In future plant several rows to achieve better pollination. I give my corn plenty of fert and water when growing.

Hiya i got given two shoots of sweetcorn, one about1inch high & the other is double in size (height) & i have just planted them both in the ground ... Just wondering if replanted wrong or too early.. Im in Vic melbourne... Its gonna b hot tday n stsying in the 20degrees all week... Also is seasol a good enough fertiliser ? Or? Will have more questions again soon no doubt (growing my collection of 24 seeds) thankyou kindly from the newbie in outdoor gardening)

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.

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.
