I think you can plant before December during spring already, as soon as the danger of frost has passed. Also, if you are planting more than one variety, it is best to do so a few weeks apart so they don't mature at the same time, because they cross-polinate between species.

I only have a small home garden. I generally start planting my first batch around more d Sept and the every 6 to 8 weeks thereafter. If my first batch was planted in September , my sweet or green corn is harvested in Early Jan or Feb. I plant pumpkins in between the rows and when the corn is about shin high I interspace with climbing green been. The pumpkin protects the corn roots and the beans provide nitrogen.

i have been monitoring the soil temperature for a couple of weeks and it seems to be above 12 to16 degrees most days , sometimes in the early 20 I measured the soil temperature at 25 mm below ground level , seed sowing recommendations the seeds went into the ground today and as we speak the sprinklers are on should come up in 2 weeks , fingers crossed I followed the 3 sisters format as close as I could , my beds are not 5 feet wide

Dear Sir, i have planted papaya trees in my yard. They are organic & flourishing very well . People got amazed when they see our papayas, they look different from south african pawpaws. They are very sweet & juicy, have also smaller trees growing. I also planted brocolli, lettuce, carrots & spinash. My challenge is not having enough space to grow all these bcos am now planning to plant sweetcorn, watermelon, spanspek or canrteloupe & pumpkin. I need mentorship & somyeone who can help with a land to lease or make partnership to expand business. Your advice & help will be much appreciated.

Greg, I'm at Albion Park NSW 2527. Can you better explain the 3 sisters method of growing corn and beans? When you say, '2mx2mm squares', how many corn plants and bean plants should I put in per plot? Also, distance apart, etc. Do I plant the corn and beans at the same time? Would it work with corn and snow peas as well? The more detailed your response, the better..... Thanks for your help, Rob.

Plant the corn first, as suggested on the packet, in a grid pattern, so the top flower head will fertilize the corn which grows on the side of the stalk.when the corn is about 20 - 30 cms high, plant climbing beans between the corn, and train them with a twig to grow up a corn stalk. Once the beans are up plant a small vining pumpkin, like butternut,so it doesnt keep growing outside of the area. This keeps the soil covered and cool for the corn and beans. Water by putting it down between the leaves, to keep powdery mildew at bay.A handful of dry chicken manure spread around the corn and beans will help as the corn is maturing. Pick beans carefully, and help pumpkins by fertilizing female flowers with males, due to the lack of bees. Good luck
