I don't have much space... has anyone had success with growing corn in a large raised bed? Thanks!

Corn takes a fair bit of water so keep the drink up to them. They do have a pretty good sized root system so it would depend on the depth of the raised bed. I've grown them OK in 600mm deep beds.

Would they do well in a 3 foot or 914 mm bed?

CORN701 does not grow in the ground I tried several times, it grew once after that it doesn't. Second time seeds became big and never progressed in the ground.

Hello,I am about to start sweetcornfarming in Dar Es Salaam, Kigamboni, Tanzania. I intend to buy some different types of Sweetcorn to find out which type I should use. What do you recommend me to start with and fits for lowland, rain about 1200 mm per year, subtropical area, 2 rainperiods. Zone 12.The sweetcorn will be sold on the streets as boil and eaten as streetfood. I hope we will be able to plant the seeds all over the year for selling. Can you recommend different types which I can order and test in a little scale to see which type or types of your products works best for us? Also give me prices for the test. 50 or 100 seeds of each are enough. Before we place a larger order I must know which one works best in my area and environment. I looking forward for a fast response. I need the grains to be delivered to Sweden in a short time. Do you also have an WhatsApp telephone number where I can reach your support/service? If you can supply me with the right corn, can you give me an advice where to go for finding right products? Best regards Jerry Pettersson+46705556411
