Timely Tip #3

May 15 – 22

Time to protect your newly planted chestnut trees from deer.

Some growers use cages or a 10-foot-tall perimeter fence around their entire orchard. Those are both okay and we know growers who use these practices in their orchards. However, there is a simpler and cheaper method. It’s a product called Green Screen (Figure 1). It has worked extremely well with our trees. The good news is that deer problems “grow away” if you can keep the deer from stunting your trees.

Green Screen is made in the USA and is 100% organic. Ideal for gardens, farms, cemeteries, orchards, vineyards, golf courses, garages and sheds. Inexpensive, easy to use and safe.

Michigan State University used them in their cultivar trials and once they were on the stakes, the young trees were never touched again. It doesn’t smell that bad, so how they work is not known or our problem. But they do seem to work well.

No matter what you use, protect your new trees with something, but these little ‘stink bags’ cost about $0.80 each and are well worth the investment (Figure 2)!

They do attract dogs and bears (Figure 3). If you are in a bear area, there are reports that the bear go after the bags. If in an area with dogs or if you have dogs, use another products as dogs seem to love the bags as much as deer hate them. I have noticed my own dog trying to eat the bag. But these bags really work. One helpful hint. You can hang them from the stake about 4 feet high or you can hang them from a separate stake in case something grabs them as runs. Then it is not take the tree’s stake with it.

Figure 2. Ready to use. Easy to attach to stakes. We find it works nearly the entire year. So much easier to use than cumbersome deer fences.
