I've got no experience with sweet potatoes so can't say anything about them. But agree with the above that one pepper per 5 gallon container is the max. For the bigger containers it would depend on the dimensions as to how many plants you could put in them. You don't want to crowd them.

Black plastic nursery pots that are actually 25 gallons? Are you really sure about that? They would be bigger than a 1/2 whiskey barrel, about the size of 1/2 a 50 gallon oil drum. Have you considered the difficulty of moving the weight of such a container when it is full of soil and plants?

Then there are the problems of filling containers, any container, with things like "soils, shredded leaves, compost, etc." that aren't recommended for use in a container.

One pepper plant in a 5 gallon bucket filled with a good soil-less potting mix will probably do ok if fed and watered regularly and easy to move. Sweet potatoes are a whole different ballgame.

I have grown 2 Porto Rico bush variety sweets in a 25 gallon barrel and got fairly good production but that was with ProMix professional growing mix in the barrel. And I sure wouldn't have tried to move it.

yeah they are big maybe only 20 gallon or so...We have several heavy duty d

I measured 23 diameter and 18 inches tall..

. I bought two first thats all they had then bought 5 TEN gallon sized.

The owners have their garden in such like peppers, tomatoes and squashes around the greenhouses outside

Later Then found lots of them for sale at another Nursery bought more. Now still filling them....

several years (at former home), ago grew SP first time

and grew in bottom cut off totes. Did real good for that

I need to get my green beans agoing too Prev grew them in garden Ky Wonders ...mostly

Jason in "Container gardening" is supp growing them in buckets with a central

tower support

thanks yall

I have heard of people with some success with sweet potato in containers. Sweet potatoes love heat so this may work to your advantage. I think the problem will be watering. If you grew sweet potato several years ago then you know they put out massive top growth which will have massive water requirements. If sweet potato have water stress then production suffers. Evidence suggests that the number of tubers under the main stem are dictated within the first 16 weeks. Stress from water or low temperatures can cause your tubers to lignify and become pencil roots instead.

yeah had great sucess growing them in large 3ft wooden boxes and even better in 6 by 4 and bigger wood "boxes"

boxes of untreated pallet type wood etc for sides even used old oak flooring with the unfinished side facing in

Last year yield wasnt so great cause I didnt realize thatt letting the wandering foliage "root" would effect the tubers.

Have been growing in "containers" only for like 7 years...they were so easy to harvest too...

thanks all

I just Google almost the same question. Apparently you can fit six sweet potato slips in a 20 gallon grow bag. I'd only put one pepper plant per 5 gallon container. I do have two pepper plants per 10 gallon container. Hope that helps.
