Sweet Potatoes? Please help
« on: October 20, 2019, 10:06:34 AM »
So every year for the past few years we have been growing sweet potatoes or at least attempting to with very disappointing results. I have looked through YouTube scoured through academic papers but so far no real luck. I've been hoping to grow large tubers, the NPK suggestions really aren't clear. The only universal thing agreed upon seems to be loamy/sandy soil. Can anyone help clear this up for me?? All of my tubers thus far have been tiny 50-100 grams at most

Like most plants sun plus water plus time equal growth... lots of nitrogen equals lots of green growth not so much tuber growth... in my experience

Also maybe try another variety?

I've tried other varieties with the same result. Tiny undersized tubers. I am aware that high nitrogen ratio is not helpful for tuber growth. What I would like to know is what the ideal NPK/micronutrients are for efficient tuber growth.

Unless you have something taking up that nitrogen... it's still in the soil. Grow something else then try again.

You need as much heat and sun as possible. Given your cool climate you might try growing on black plastic to warm the soil.

They really seem to appreciate heat and well draining soil. I grew a patch in an area with moist soil and only got a few small tubers despite ample foliage growth. They rot quite easily.
