I apologize for this delayed reply to your gardening question. The spring rush has brought a deluge of questions and we are working hard to catch up!

Trees develop surface roots when the soil is heavy or when surface erosion washes the soil away to expose roots. I suggest you bring young some soil mix with compost to spread around the tree and cover the surface roots. If you just spread soil three or 4 inches deep at the most and if it is mixed with compost that should not damage the tree at all. If you want your double trump tree to have a single trunk choose one of the two trunks and cut the other off at ground level. Some trees are growing to have multiple trunks and others to have single trunks but you can always remove any additional trunks you want taken away. The sooner you do this the better as the energy can then be directed into the remaining trunk. Be prepared to do some additional printing as resprouting occurs near the base where you cut the trunk off.

Thanks for the question. Best wishes for a wonderful gardening season. Please stop in again soon!
