Arrowroot does best in the ground, but I needed to pot some up so I could take it with us when we move. I dug up a small tuber so it doesn't overtake the pot and decided to create a self watering pot in a bucket (buckets have handles so it's easier to carry). Now it's a bit boring having just one little stick of arrowroot in a bucket so I added a comfrey and strawberry.
I have to say this little guild is perfect and they have grown so fast! These three plants all prefer to stay out of the full afternoon sun, and they enjoy the more consistent moisture of the self watering pot. I did buy a fresh bag of potting mix for this one as comfrey pulls up all the nutrients. Since I've been cutting the comfrey to feed the chickens and add to any plants that need a boost, I will have to start feeding this pot regularly.
They say once you plant comfrey you'll never get rid of it... unfortunately mine disappeared when Ray helped me weed. After months of searching I was very lucky to find this single plant for sale. The lady at the nursery told me they finally filled all their special orders and only had one extra - it was waiting for me! Hopefully I can propagate it soon so I can have a backup - I'm not letting this plant die!!
