Mosquito Netting

We have 3 cherry trees growing in our backyard. They are about 8 years old. The varieties are Bing, Rainier, and Royal Rainier. In previous years, I have found maggots inside some of the cherries. Last year, most of the cherries were infested with maggots, especially on the Royal Rainier. I noticed small flies buzzing around the fruit. I suspected that the flies were spotted wing drosophila (SWD). Most of the cherries were brown and inedible looking from the insect damage. I ended up throwing all of them away.

I was on the verge of removing all of our cherry trees, because I didn’t want to implement a spraying regime. I had the same problem with raspberries in the past. I sprayed the raspberries back then, but it didn’t help. I ended up removing all of my raspberries. But I wasn’t ready to give up on the cherries just yet. It has taken several years for them to reach the size they are and to start producing fruit. Also, removing the cherry trees now would require much more work than removing raspberries.

So this year I tried something different. I have netted the cherry trees with bird netting in past years to keep birds away, but the holes in bird netting are too large to keep out insects. The only type of netting I am aware of that has a mesh fine enough to keep out small flies is mosquito netting. So earlier this year, I bought some mosquito netting.

After our cherry trees were out of bloom in mid-April, I wrapped mosquito netting around our Royal Rainier cherry tree and tied it with twine around the trunk. I then rolled any open parts of the netting together and sealed the openings with clothes pins to keep insects from flying or crawling in. It helped that I have pruned this tree to keep it under 8 feet tall. I didn’t bother to net the other two cherry trees, because they set very few cherries this year. Here is what our tree looks like netted.

Last weekend, I harvested most of the Royal Rainier cherry crop. Here’s what they looked like inside the tree.

And here is what they looked like after harvest.

They look beautiful and taste amazing. Not one of the cherries appears to have been touched by birds or insects. We have eaten most of them already, and we haven’t found maggots in any of them. The netting also allowed me to leave the cherries on the tree long enough to fully ripen.

Netting a tree is extra work, and it is probably not practical for large trees over 10-12 feet tall. However, I think it was worth the effort. Mosquito netting is easier to work with than bird netting, because it doesn’t get caught on things as easily. And it keeps out all kinds of pests including insects, birds, and squirrels.

In fact, I am so happy with the results of the mosquito netting that I am using it to cover some of my other fruits and vegetables. For example, I am using it to cover broccoli and cauliflower to keep out cabbage moths and aphids. I am also using it to cover my blueberry bushes as shown below. Even though the netting has a fine mesh, it appears to be letting in enough sunlight for these plants to remain healthy and grow.
