Easy installation – step-by-step guide

For trees with a large root ball (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 root ball depth + 10 cm.
2. Determine the size of the hole, which must be at least root ball diameter + 60 cm in a square shape.
3. Place stone wool batts in a square around the root ball. Cut to size if necessary.
4. For limited space: Place batts where there is space. If there is not enough space all around, position batts 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 sit. (The top of the root ball should be about 10 cm below the soil surface).
6. Place the tree in the center and fill with growth soil inside the batts and sand/soil on the outside simultaneously.
7. Tamp the soil thoroughly to ensure stability.
8. Secure the tree with 2-3 stakes, placed on the inside of the stone wool batts.
9. For very clayey soil: A gravel base under the batts is recommended.
10. Finish by adding between 80-100 liters of water per stone wool batt.
11. Water 5-7 times during the first two years. It is important to use surface watering with about 65 liters per stone wool batt per 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 in damaged areas.
2. In case of struggle: Place stone wool plates in a cross pattern 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. Cut damaged roots off 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 batt.
7. Water 5-7 times during the first two years. It is important to use surface watering with about 65 liters per stone wool batt per time.

For beds:

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

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