I found a sweet potato tuber with shoots about 2cm long in the vegetable storer in the cupboard. I want to know if it will keep for a couple of months so I can plant it out when the threat of frost has gone . I paln to plant tomatoes, capsicum, peas and chiilis at the same time..... mid October ish.

next time plant them in a very large pot, wine barrel etc and keep indoors by a sunny window till frost passes. just trim the shoots that over hang or trellis them

I didn't think so, but I read on the blog of a Canadian gardener how she had a massive crop last summer, so I'll have a try this year. She cut the sweet potato in half and suspended it with the end in water until it grew shoots, then twisted the shoots off and planted them once all danger of frost was past. She also warmed the soil with black plastic.

Have seen them at Kim's groceries (around the corner from Maccas in civic), also sometimes at "Asian Supa grocery" at Belconnen. You can also get seedling from Daleys fruit trees. Good luck :)

Hi Santy, The fresh food markets (belconnen markets and fyshwick markets) have sweet potato. Most often they only stock the orange variety, but I have seen white and purple (purple skin, white flesh) there also. I am going to try to grow them this year, but keep in mind that they are not really suited to our climate!

Hi there.. I harvested my Kumara in March and unfortunately most of them tubers had multiple small holes in them. Looks like some type of insects got there first and ruined it. Is there anything that I can spray them with and kill them little bugs before they ruin my crops next season.. cheers
