How and when to plant conifers
You can plant out conifers in a plant container in the garden throughout the year, and conifers with a root bale from the end of August already. Early autumn planting is advantageous for these trees as they begin to produce roots immediately on warm autumn days. They thus establish themselves very early, get through the winter better and sprout both earlier and stronger in spring compared with conifers planted in spring.
Conifers which are frost-proof to a certain extent, such as Blue Atlas Cedar (Cedrus atlantica ‘glauca’), Himalaya Cedar (Cedrus deodara), Umbrella Pine (Sciadopitis verticillata) or Siberian Cypress (Microbiota decussata) should rather be planted in early spring.
Secure conifers standing alone in exposed areas, for example freshly planted pines (except dwarf pines) with a tree stake, so that the freshly sprouted roots do not tear off when the gusty autumn wind tugs at the plant. Especially in
the initial growth phase, ensure that the newly planted plants do not dry out. It is helpful to add 20 litres of water per square metre at the right time. However, it is also helpful to surround the conifers in the initial growth phase with a straw mat as wind protection.
Planting a conifer hedge, for example Thuja:
With all planting work for conifers, never plant them in compacted soil. Always remove soil compaction beforehand by loosening the earth deeply around the planting area so that the conifers can easily grow roots.
Tip: Conifers provide structure in the garden and therefore approximately a third of garden plants should be conifers. They are especially important in the winter months for perception of space in the garden when most deciduous trees are bare. Around this time, they also offer garden birds vital protection from precipitation and icy winds.Source: www.gardena.com
