We did this ourselves as we have a VERY (underlined) windy site, so windy that
almost nothing grows--we've tried gorse, radiata, corsican pine, flax, This
year we are trying broom, manuka, rugosa,
We had hoped that ripping might aid root development, but the trees seemed to
"swirrel around" making a little funnel in the earth. they were planted at 1
year and died before their second birthday. Sad but true.
This is in a site where wind is the limiting factor, at the top of a range of
hills. We get poor grass growth on the plateau of these hills, so we think we
needed some shelter.
Any ideas on what species to try? Could use some help. I'll try anything.
