Forestry Commission nursery,Lob's Slack,
Delamere,Cheshire,UK. One of the tunnel bays in image 5169084 filled with cuttings of genetically improved Sitka spruce. Once rooted and then hardened off, they are lined out to grow on before going to the forest. Although the subsequent plants are more expensive than those grown from open pollinated seed they have greater vigour,better form and better timber.Their stems tend to be thicker,at planting,thus less prone to Hylobius damage.
