Week 8 – Radiata Pine
Monday, June 1 – Sunday, June 7
This week’s weed is probably not considered a weed by some. We Blackwoodians are fond of our giant pines at the sports ground and they form part of our cultural landscape.
While not declared “noxious” in Victoria, the species does invade our forest and outcompetes our native species.
Where safe to do so, small trees can be killed by chopping them down. Again, where safe, larger trees can be simply poisoned and left in situ.
There is a bit of ring-barking going on in Blackwood. That’s good. But it’s even easier to poison pines. This study is a good guide – https://www.dropbox.com/s/mzdl4xn6a55rev5/Drill%20and%20Kill%20for%20Pines.pdf?dl=0
Known as “Drill and Kill”, it involves drilling holes 35cm apart around the trunk (angled down at 45 degrees) and injecting 10ml of straight herbicide into each hole.
