I have planted slips that I grew about 2-3 months ago, The slips are in soil, in large plastic tubes with holes in the bottom & sides to drain as much water I can. We have had soooo much rain, & I checked the top & bottom soil. The top soil is dry, but the bottom soil is very wet. Should I leave them to do what it automatically do itself to grow, or remove the soil & slips & start again? I dug to bottom of the vines to see how they have been growing. The slips have lots of roots.

Lol... Not suitable for growing in Oz? Yams are a staple diet for our Indigenous Peoples, they've been growing them for centuries in Australia.

Growing orange sweet potato from sprouting end cut off. I have been told if I do it this way you will only get vines & no sweet potatoes. Told it was best to plant vines with roots to start with. I have rapidly growing vines, just waiting for it to die off so I can see the results.

Hi Darla. Sweet potato can be grown this way, but the shoots need to be detached from the tuber and planted out separately, otherwise all you get will be vines. We did it this way, and from one sweet potato to grow the sprouts (slips) we ended up with about 15-20 plants.

Is that white when raw or cooked because real kumara are yellow or lemon if you like in the inside.

Kumara or sweet potato is so easy to grow here in Perth WA, It grows like a weed , and spreads out through your garden over two years.
