Q.Horse Chestnut Replanting
My partner grew a horse chestnut from a conker 25 years ago on a river bank before transferring it into a big planting pot. It’s is currently 4ft and we would love to plant it back on the river bank as we have just purchased the adjacent property. Do you think the tree will survive this or should we keep it in the planter?

If it is only 4 feet tall, I would go ahead and plant it on the river bank. It will likely grow quickly.
