They cut this off from my post. You need a slip about 18

I live in Fairlie South Canterbury and want to know if I could grow Kumara here and what month should I be planting them

I have two furiously shooting kumara that have been growing in the pantry (!) Whilst I was overseas. I'm located in a very sunny spot in Auckland, is there any point in attempting to grow them now? (End Feb)

Give it a go.

Pop it in the ground, that way you will have slips for next Spring. However, if you get cold winters over there, pop it in a pot, so you can move it to the garage or shed during the cold days and nights.

When is the best time to plant out the new growth from a tubar. I have a sweet potato that has sprung heaps of shoots. I'd like to put them into pots. Will they grow over winter in I keep them warm or am I wasting my time?

I am in Adelaide -Temperate, and I leave mine in the ground over winter.

Put them in the ground if you have a garden. Cover with some shade until they start to establish themselves. Sweet spuds are grown all year round in Bundaberg - 30-35 degrees in summer.

Does growing sweet potato deplete the soil of any particular mineral. I have grown a good crop of the sweet potato & intend to plant some sweet corn on the next full moon. Is there a particular fertiliser that’s advisable to add, prior to or as planting? I understand that all soils are different, but assuming all things are equal, is there something to add?

A bit of fert in the soil now and when the plants are about 12-15

Most if not all plants need some sunlight. Photosynthesis is the chemical process used in plants to convert energy in the form of sunlight into chemical energy in the form of sugars or other carbohydrates. The general process involves the combination of carbon dioxide, water and light energy to produce oxygen and carbohydrates. In plants and algae, this process occurs in an organelle called the chloroplast. Some types of bacteria perform photosynthesis in a slightly different process which does not produce oxygen.
