Hi! As a fellow Floridan I feel your pain on our awful soil. Horseradish tend to have some aggressive spreading tendencies so putting them in a 5 gallon bucket or one of those bags used for growing potatoes would work well but I wouldn't place it in the ground if possible. I'd recommend planting in the beginning of fall (around the first time we get below 90) with well draining soil, they don't like wet feet, and making sure to give them shade in the afternoon as our Florida sun can be mighty aggressive when it reaches its peak. I would use a compost or essential minor elements (I tend to use this on veggies, herbs, and fruit I think it makes them taste better in my opinion) to fertilize it around 4 weeks after planting. Around early spring you should be good to harvest and enjoy!
