I would like to try to grow kumara potatoes in our green house as you say they need a long growing season. Can you advise me where I can buy tubers/seeds? Many thanks Graham

I get my slips from Pioneer Garden and Seed in Villa Park IL. I grew sweet potatoes for two summers with great harvests. I am not sure why they say 5b is not good for sweet potatoes.

Can you grow from store bought Sweet Potato

I grew a crop from store bought sweet potatoes - just have to wait for them to start shooting then plant to leave the shoot tips (with 2 small leaves) showing . I have had good crops for a couple of years with minimal attention other than normal weeding and watering.

Hi, I tried growing sweet potato here in Lismore, NSW. The plant grew well, but when it came to harvesting the tubers, I found that they were riddled with small white grubs. I have tried to google what the grub is and how I can control it (for next season) but the information is limited. Has anyone got any idea what the grub might be and how I could control them? Thanks Simon

Sweet pot grow well in the Brisbane area all year. Just a guide for fellow brisbanites if u live in a frost free area of bris ie bayside, use the tropical setting, sub tropical is more based on the Sydney area and from experience have learnt if u follow tropical instructions, u get heaps more luck. Give it a go.

I live in the Hunter Valley and the major supermarkets stock gold swt potato all the time.I believe they grow like regular potatos, so try buying some and store them in the cupbaord until they shoot.
