What fertilizer should you use prior to planting?

Go on the internet and find out what N P and K do for plants. Then think about what you are growing with sweet potatoes.

I find that the purple ones grow the best in my garden. Problem is I have miles of plant and not so many tubers. Going to use some of the advice I have read on this page and feed with seaweed.

Don't fertilise with nitrogen.

Hi June. I plant a sweet potatoe around August or September and let it grow wild. Then I take cuttings from that about 3weeks before Christmas and plant them out ,making sure I water them in really well for the first week or so. Then I harvest them just after the first frost with pretty good success.

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
