I'm in Ipswich Qld .I've planted a whole tubor of the purple sweet potato ( after it produced roots in water) and it's shooting up beautifully, do I break these off and plant separately? or try to grow roots in water first? I have had no luck at all with the orange sweet potato.

Cut it into 4-6 pieces and plant. Then when they have grown for about 2 mths take some of the vine about 5-600mm long and plant in the soil laying horizontal with just the end sticking out of the soil. Water well for week or so.

Did you read the notes here. I suggest you do and pay attention to when to plant.

Can you please tell me what is the best type of fertiliser to prepare the soil for kumara?

Any general fertiliser - but probably something with a fair bit of P in it. N P K - something like 10 -14N, 6-10 P, 10-15 K.

When my tomato bed finished i refilled the bed with conpost and the sweet potatos started growing. I got quite a few potatoes and pulled them out in September to replant tomatoes. I couldnt get tomatoes to grow that summer so i gave up and let the je sweet potatoes come back naturally. Should i try for tomatoes again in that same bed? If so do i need to help the soil in any way? Thanks!!

I have been told sweet potatoes are a big consumer of nutrients from the soil - other words not much nutrient left in the soil after the crop Tomatoes would also take a lot from the soil. Did you add compost or totally refilled the bed with compost again. If the compost is not totally broken down then it will take N from the soil - therefore very little N for the intended crop. Look to the guide here for planting - although it has no planting time for sweet potatoes in temperate climates. After each crop you need to do one of two things - add completed compost, manures etc and make sure this is all broken down into the soil. Or you hit it up with some all round fertiliser. Also give your soil a rest for a few months and add compost and turn it in.
