We have a couple chocolate Joe Pye weeds planted in our flower beds next to our patio. I simply adore the foliage and the white flowers that bloom in late summer/early fall. However, I'm finding the sheer number of flies attracted to the plants overwhelming. If they would stay on the plant, that would be fine, but they usually roam around into our gathering/play spaces, too. How can I control/eliminate the flies?
I have heard of using any citrus, clove and/or basil oil in a suspension with a little dishwashing liquid (2-4 Tab. per 1 gal water) as a spray. Also, planting basil around the plant is supposed to repel flies. Tansy, rue, rosemary and marigolds act as insect repellents. If this doesn't work, neem oil should.
Will Joe Pye weed continue to come up every year if I keep cutting off the flower heads as soon as it blooms? I'm trying to get rid of it as it requires too much watering.

I planted a joe pye weed last year and the leaves are being eaten. I used an organic pest killer but it doesn't seem to help. We have had an unusual amount of rain. Could this be a cause?
Neem Oil treatment should take care of most sucking insects on your plants.
You can reapply weekly to help control the pests.
The rain my have washed off your application of the insecticide.

My cousin decided to uproot and discard her large Joe Pye plant and since I had the chance we took it and planted it in a well watered deep hole in a partly shady area a week ago. We watered it well on the days it did not rain. Now about 1/5 of the stalks have dark dead leaves all the way up and I am wondering if I should cut the stalks to a few inches above the ground and let the plant's energy just concentrate on the root system recovery. I do not know the best way to save it. More water? The soil is quite moist. Thank you.
It can be difficult to transplant successfully in the middle of the season, but your plant may recover. You will just have to wait and see. Here is some more information on possible treatments for transplant shock:

I know it grows up to 10-12 feet high, but I do not know how fast it grows. Can you tell me?
Joe Pye Weed can take a bit to become established, but once it has developed several stems it will grow more quickly.
You can find newer cultivators that will stay smaller for a home garden. Look for Gateway, Little Joe and Chocolate varieties.
Joe Pye Weed also began to boom later in the season, so planting in the back of flowers beds is a good option.

Will this plant survive if it is cut down several years in a row in late Spring. I noticed not much is coming up this year, 2017. A beautiful field of it is mowed down for a one day use each Spring for parking. I have pleaded witht these people to no avail. At least they will leave it now for the milkweed and other wildflowers.
Yes, the plants may die off if they have been cut down for several years.
My plant has brown leaves and something is eating it. It has blooms but they are not vibrant.
I would treat your plant with Neem Oil. Neem Oil works on most pests and also works as a fungicide.
