Nursery Regimes
There are three main regimes which PSS use within their nurseries to produce the best possible stock and give every single seed a chance to develop and grow. These regimes are as follows;
- Field Grown
- Cell Grown
- Super Sitka (Cuttings)
Every kind of plant is different and requires a different type of environment. The Forestry Commission has spent a lot of time and energy in researching the best environment to grow a particular kind of plant and the results have allowed them to produce the best. Trees within FC nurseries are all grown to agreed size specifications, if they don't make the grade then they won't make it onto the back of a lorry. We want all our trees to have the best start in life so they have to be big enough to withstand the odd nibble by bambi. Field Grown Seed is sown outdoors and seedlings are either transplanted or undercut and wrenched to improve quality of root systems. Trees are lifted and supplied as bare root stock. Cell Grown Seed is sown in small containers and germinated indoors in large polytunnels. Plants are moved outdoors before they are lifted and supplied with the plug of compost to protect the root. Super Sitka (Cuttings) Stock plants are raised from high value seed insice polytunnels. Shoot cuttings are taken and placed in misthouses to be grown as field grown or cell grown stock as above. For further information on any of the above, please contact John Morgan.

What's of interest
Samples of trees are tested for physiological condition using a method called 'root electolyte leakage'. Roots offer the best measure of plant condition and the less that they leak usually means that they are most dormant and least prone to damage.
