3. Then lower the box by gripping with hands on the sides and lowering it into the hole.
4. Fill sand or soil on the outer side of the box.
5. Fill up with growing medium up to the bottom of the root ball, so the top of the root ball is level with the ground height. For bare root trees, fill the entire box with growing medium 
6. Place the tree in the center of the box and fill up with growing medium.
7. Ensure that the growing medium and soil/sand are well compacted.
8. Attach ties to the tree at an appropriate height. Use 1-2 stakes and place them in the ground on the inside of the stone wool.
9. For very clayey soil, a gravel base should be constructed under the box.
10. Finish by adding 75-100 liters of water.
11. Water 7–9 times during the first 2 years. It is important to use surface watering with approximately 70 liters per time.

Tip: Use a quality growing medium to ensure strong root growth and healthy establishment of the tree.
