Planting is the surest and fastest method to establish a new forest stand. In planting, as in any other stage of the forest regeneration process, the key to success is to do the work in a correct and careful manner.
The timing of the planting essentially depends on the tree species to be planted. For example, summer planting is only suitable for spruce and silver birch seedlings, whereas autumn planning is best suited for spruce seedlings and, according to preliminary research results, for young birch seedlings. Other things to consider in the planting is the planting depth and location and how the seedlings should be protected against vermin.
Planting seedlings into prepared soil has many advantages: there is less other vegetation to compete for water and nutrients, as well as less hay and straw to cover the seedlings. In addition, the soil temperature is higher in prepared soil, which expedites the germination process and provides a fertile breeding ground for the seedlings. Planting seedlings into prepared soil also helps to deter the large pine weevil, the most formidable pest of seedlings.
