Week 7 – Holly

Monday, May 25 – Sunday, May 31

English Holly is perhaps our worst weed. It loves our wet, cool climate. It spreads like wildfire. And it’s REALLY hard to kill!

And, what’s worse, some residents of our townships grow it as an ornamental garden plant. So how are we every going to be free of it when thousands of berries (seeds) are freely fed to the birds each season, which then spread even more Holly throughout the creek-beds and gullies in the forest.

Nevertheless, it’s better to do something than nothing. So either start pulling out the little ones (making sure ALL the roots come with them) or get out the poison and get to work.

It’s a good time of year to get stuck into Holly. The soft ground makes it easier to pull out the seedlings. And the tree is currently drawing nutrients down into its root system in preparation for winter.

“Frilling” a small distance into the bark and applying 100 per cent concentrate herbicide all the way around the base of the truck is effective. But don’t expect instant results. It will take many months to die.

You also can cut a Holly down and paint the stump. But watch out that the fallen branches don’t take root and continue the spread.

Our Holly page (http://blackwoodlandcare.org.au/our-problem-weeds/holly/) has more information and identifying images.

There are also three 2013 weed maps to help, although it’s not hard to find in Blackwood and Barry’s Reef.
