I want to plant the 3 sisters, corn (maize), beans and squash, for my zone (9b) both beans and squash can be planted in Aug/Sep but I've missed the cut off for sweetcorn. Has anyone had experience of planting maize in this climate at this time? Will it work or am I likely to be disappointed? Thanks for any help. Katie

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
