It's time to plant trees and to learn how to do it!

November is the start of the traditional tree planting season for bare root trees that are two to three years old. Normally, planting of bare root trees ends in March when the plants wake up after winter and start to grow again..

But things are changing. Mechanisation and industrialisation of the tree nursery business means that a much smaller number of very large nurseries on the best agricultural land now produce many millions of trees each and they have been able to extend the winter and planting season by keeping "bare root" tree plants in cold stores up until June or even later

Then there are trees grown in germination / propagation modules under plastic tunnels These can be planted at any time as they are well rooted in a ball of growing medium but these are much more expensive and difficult to handle on the planting site. A tree planter can carry 100 or more bare root plants in a bag over her shoulder but plants in modules have to be palletised and are a bit of a logistical nightmare on large, remote planting sites.

For my tree scheme the seed of the ,"native broad leaved" species that I plant must have a known provenance; in short the seed is collected in Argyll and is certified as such. It can then be sent anywhere to be propagated for two or more years before I plant it.

Because I am not a forester I went on a tree planting training course last weekend to learn how to establish a wood and a few basic rules emerged; plant good quality trees with well developed roots, smaller transplants are better than long whippy ones, don't let anything (voles, deer, sheep etc.) eat them, control the weeds and finally the actual planting is a skilled job. Rachel in the picture plants between 1,000 and 2,000 trees a day depending on conditions, I'll get her to do mine.
