For trees with large root balls (over 80 cm) or limited space:

1. Dig a hole at least 70 cm deep. If the root ball is higher, the hole should be the depth of the root ball + 10 cm.
2. Determine the size of the hole, which should be at least the diameter of the root ball + 60 cm in a square shape.
3. Place stone wool mats in a square around the root ball. Cut to size if necessary.
4. In limited space: Place mats where there is room. If there is not enough space all the way around, set the mats down where there is space.
5. Fill with growth soil on the inside while filling the outside with sand or soil, but only up to the level where the root ball should stand. (The top of the root ball should be about 10 cm below the soil surface).
6. Place the tree in the middle and fill up with growth soil inside the mats and sand/soil on the outside simultaneously.
7. Compact the soil thoroughly to ensure stability.
8. Secure the tree with 2-3 stakes, positioned on the inside of the stone wool mats.
9. For very clayey soil: A crushed stone construction under the mats is recommended.
10. Finish by adding between 80-100 liters of water per stone wool mat.
11. Water 5-7 times during the first two years. It is important to use surface watering with about 65 liters per stone wool mat at a time.

For trees that are struggling or have root damage:

1. Dig a hole 70 cm deep and about 25-30 cm wide between the large roots or at damaged areas.
2. In case of struggling: Place stone wool plates in a cross shape out from the tree without getting too close to the trunk.
3. In case of root damage: Place the plates at the end of the damaged roots.
4. Trim damaged roots close to the stone wool placement.
5. Lower the stone wool and cover the hole with existing soil or replace poor soil.
6. Finish by adding between 80-100 liters of water per stone wool mat.
7. Water 5-7 times during the first two years. It is important to use surface watering with about 65 liters per stone wool mat at a time.

For beds:

1. Dig a hole about 40 cm deep, depending on the size of the root ball.
2. Place stone wool mats flat at the bottom of the hole.
3. For root ball: Set the plants on the mats, and fill up with growth soil to the terrain level.
4. For bare-root plants: First fill up with growth soil to the terrain, and then plant the plants in the soil.
5. Finish by adding between 80-100 liters of water per stone wool mat.
6. Water 5-7 times during the first two years. It is important to use surface watering with about 65 liters per stone wool mat at a time.

Tip: Stone wool mats can be used as an effective solution to improve growth conditions in demanding soil conditions.
