Horseradish is grown from root cuttings. If you know someone who has it in their garden, just one piece of root will start off for you.

Dig a deep hole and refill with compost as the horseradish has a long taproot. Plant it and then leave it alone. Apart from constant wet or cold, horseradish will grow in any part of the garden.

Horseradish is an aggressive grower and will quickly take over the garden. It will also grow well in a deep container or sink an old bucket in the ground to prevent spreading. Otherwise, remove all the plant when you harvest it and save one piece to replant.

Can be planted in early Autumn or Spring

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!
