How To Use Your Pump Sprayer To Reach Japanese Beetles In A Tall Crape Myrtle


I had three calls today to let me know that the Japanese beetles had made their appearance. The last message was a text from my good friend Randolph who wanted to know how to get the pesky beetles that were eating up his crape myrtles.

Japanese beetles in the Southern U.S can wreak havoc on plants such as roses and Crape myrtles. They don’t stay around long but they eat a lot

I started to explain the process to him but then I decided to get my friend Johntheplantman to write an article with pictures. Here’s how you do it.

Ace Hardware sold me a sprayer for around ten dollars. That’s reasonable and it serves my purposes. Here it is:

An inexpensive pump sprayer. Always clean and rinse the sprayer before using it on plants. Be careful

The most effectivechemical I have found for these beetles is Liquid Sevin, which is an easy to spray version of the old fashioned Sevin dust that has been used by farmers and gardeners for many years. Liquid Sevin is one of the safest insecticides on the market, but be sure to wear eye and face protection when applying it.

Liquid Sevin is a relatively safe insecticide and it works on the beetles. Be sure to wear safety glasses and face protection.

Most, but not all, sprayers have an adjustable nozzle similar to the one shown in the picture below. The expensive sprayers have a brass nozzle while some of the other sprayers have strange nozzles that won’t work. Here’s my nozzle:

The nozzle may be twisted to set a spray pattern. Here is a medium spray pattern

If you tighten the nozzle, the spray pattern becomes finer and wider.

Tighten the nozzle to increase the fan

And if you loosen the nozzle the spray pattern will become more concentrated and will shoot for a greater distance. I used this spray pattern for a good picture but you may with to experiment and you will find that if it is set “just so,” it will look like a high-powered water gun and shoot 20 feet or more.

Loosen the nozzle and experiment until you get a long, narrow stream. This will reach way up on the crape myrtle or other tall plants.

So mix the Liquid Sevin according to directions and set your sprayer. (Disclaimer: If You are against the use of this method of control, you may wish to get a Japanese beetle trap. If either of these procedures hurt your sensitivities in any way, I’m so sorry.)

Preventing inch worm damage on Knockout roses and watching the garden develop

Getting ready for the garden tour—part four

Last Tuesday morning, I was sitting on the porch eating my peach yogurt, drinking green tea, and watching the lovely spring day develop when the phone rang. I looked at the caller i.d. Yep, I had been expecting the call.


“They’re here,” the female voice replied.

I said, “Ok, I’m on it, thanks a lot.”

She answered, “No problem, glad to help. Good luck with your mission.”

 I had asked Jennifer to watch out for signs of inch worms because she lives down by the river and they show up there first. Last year there had been a bumper crop of inch worms and they had eaten up everything in sight right at the end of April. I thought they might be early on account of the mild weather this year, and I was right. I have been pampering a group of roses on the mountain to have them ready for the Rome, Georgia Junior Service League’s garden tour on April 28 and I sure didn’t want the inch worms to eat up the leaves and flower buds. I finished breakfast and got in the truck. When I reached the job site I found that I was just in time.

The damage was minimal but I could tell they had started. I saw a little hole here and another there. The caterpillars seem to come out at night and eat away the leaves. They only stay around a few days before making a cocoon and going into the next stage of their life. But they sure can eat during those few days. I got out my killer liquid sevin and the spray can.

A good dose was applied to the rose leaves, over and under. I also went around and took care of the Japanese maples and hydrangeas

As a reward for myself for a job well done, I went for a walk through the garden to see what was going on and to guess what would be in bloom for the garden tour. I first noticed the plant that we call “English dogwood” which, I think is really a mock orange. If you know the variety, please leave a comment.

English dogwood or mock orange?  (or are both correct?)

I stopped to admire the first open flower on the rhododendron by the fountain.

The hosta has really come out in the last week. I hope the deer don’t get to it.

I was really tickled to see the development of the flower buds on the Nikko blue hydrangeas. They just might make it for the show.

And the oak leaf hydrangeas have really done some growing. Here is a picture of the working flower buds.

I now have three weeks left until the tour. This coming week I will open the pool and we will do all of the last minute pruning and put down a hundred or so bales of pine straw.

Next week will be the “big mow” in which we cut about ten acres of hillside grass.

And then the final week will be to get the fountains clean and working, plant the flower beds and urns, and fix everything that ain’t been fixed.

Will John the plant man make it?  Time will tell.
