Corn needs plenty of regular watering - like each couple of days.

can i grow corn in planters?If, yes any recommendation on planter size and number of corn seed per planter. I have very small area in backyard with very sandy soil and nothing grows there easily.

I got great information on using fabric grow bag planters from YouTube. Her channel name: Growfully with Jenna / Title of video: Can I Grow Sweet Corn in a Container? Absolutely! / Date published: Sep 1, 2020 / Length of video: 5:39 She suggests using 20 gallon grow bag planters. No smaller. She suggests making 6 holes in soil with 2 seeds in each hole and thin if need be. She says she does two seeds because every now and then, you'll get a seed that won't germinate. I hope this helps. Please check out her video. :) P.S. She does discuss the type of soil to use because corn is a very heavy feeder. She says use 50% mushroom compost and 50% garden soil.

Try and buy some soil or find free or cheap soil and improve your soil with manures and compost.

Can i plant corn maize in pots?

You sure can I grew corn in pots last season, I used 500x390mm pots from bunnings (the biggest plastic pots they had) I had 9 pots in total in a cube with 3 corn plants in each one and they grew well, those pots are way to heavy for the wind to blow over. I have also used milk crates if you have any of them lying around just chop up your old compost bags and line the inside of the crates and fill, they're really easy to move around they're actually easier to move around then the big plastic pots haha.

Corn should be planted in blocks, that is 2-3 or more rows for pollination reasons. It is probably up to you - do you want say 20 x 30mm+ pots. When plants are 1.2-1.8m high they can blow over in the wind.

I am coming to the end of my Corn harvest. I have noticed that the corn is now poker dotted with white & yellow corn. All of my corn is from the same seeds I just staggered the planting to have corn for longer. Also the caterpillars are more frequent as are the gaps in the corn. Are all these normal for end of season "problems"?
