I am considering growing sweet potatoes in a large container.
I am considering using a straw and sand mixture in this plastic container. I am unsure of ratio to use. My thinking is to fill to half with the straw. Then, wet. Then fill with a half-sand to half-compost mix. Then a sprinkling of straw on top of this final layer at the time the seeds are planted.
The hope is for some fluffy substrate for the sweet potatoes to grow as much as possible and not be hindered by compacted soil. The fluffiness will make the container not as heavy as well, since it is such a big container. I'm planning on a 18" wide pot that is at least 16" deep. If I can't find one deep enough, I'll probably cut the bottom off. But I'm hoping I won't have to do that if I can find two or three really big pots.
The sweet potatoes, since I am really really looking forward to them, will be watered with compost tea twice a week. That's the plan, and subject to change of course.
Anyone else growing sweet potatoes in plastic containers?
