When landscaping around your property, you may wonder how much it costs to plant a tree. The answer depends on a lot of variables. If you are planting a seedling or very small tree, you can probably dig the hole yourself. If you are planting a more mature tree, then you may have to pay someone to dig the hole. There is a cost to the tree itself. Again a smaller, less mature tree will be less expensive than a mature tree. If you get a larger tree, there will also be a delivery charge from the nursery. For any size tree, you will also need to stabilize the tree until the roots take hold. Stabilizers are not expensive, but they do add to the cost. Finally, the ongoing cost of planting a tree is watering costs and fertilizer costs. All of these costs vary from location to location. For the best estimate on how much is costs to plant a tree, call your local nursery.
