[CANUFNET] Tree Planting Programs

[Mark B]

Hi Julian,
So true about survival rates   Planting trees in appropriate sites, and the correct species selection. We all ( Arbs,LAs and Hortics) can get wrapped up in ‘ trendy’ trees at the time; with tough species or cultivars, then end up with monocultures. The Elm, Norway Maple  and Ash plantings have shown us this over the years.  

I would like to know now how are dealing with EAB and like Ash die back here in the UK. 

What trees genera and species are being planted? 

Is the tree population being planted diverse enough to diminish another DED or EAB onslaught?

Out here on the west coast, summer drought is now our new reality and watering restrictions are commonplace, and even when not enforced, watering is expensive. On some sites I am finding it hard to locate anyone who can water trees well -  as opposed to simply dumping x gallons of water on the ground and assuming it will work.  I also find that gator bags have very variable success. Just because they are there does not automatically mean they work. They need filling regularly, and they need maintenance. I am seeing a lot of case where they encourage moulds / fungi and insect when placed too close to the tree trunk, and other cases where ants seem to love the moisture but plug the drains holes with mud.
