- Place a suitable substrate in the hole. To do this, it is recommended to mix black soil, sand and sawdust in equal parts. Also, when planting spruce, it is worth using nitroammophoska and a root formation stimulator.
- Place the seedling in the hole. This must be done extremely carefully. After which the hole should be sprinkled with earth, compacted and watered. When placing a seedling in a hole for planting, it is important to consider that its root collar should be located flush with the ground surface.
- Water the tree with water. For this, it is recommended to use 50 liters of liquid.
- Cover the tree trunk circle with a mulch layer. To do this, you should use peat or sawdust. This procedure prevents moisture evaporation and stops the active development of weeds.
During the first time after planting, it is worth shading the young tree with mesh material so that bright sunlight does not fall on it. Within a week after planting, it is worth using a solution that stimulates the formation of roots. In this case, it is recommended to use “Zircon” or “Epin” for spraying branches.
