This beetle was on our car at the Ranger station close to McKenzie Pass on 6/1/21. It is the largest beetle that I've ever seen. Photo included. I have no idea what it is and tried looking it up in various insect ID websites with no luck.

Severe sudden leaf disease in my flowering Hawthorne, The Dalles, OR #753785

Asked June 03, 2021, 2:40 PM EDT

After reading the article in the following link, I am concerned that this is an intractable plant disease and that I should have the plant destroyed. https://www.itv.com/news/channel/2015-06-02/disease-threat-for-blossoming-hawthorn-treesarea But when I look at the picures of Fire Blight, it looks different to what is happening with my tree. I have a quince next to it that are being affected; crab-apple across the street is unaffected. The architecture of the leaf is preserved and the areas between the veins becomes translucent. There are not raised elements. The leaves curl and then fall off-ghost leaves on the ground. Poor thing has not been fertilized in over 13 years. I'll work on getting some pictures.

White sticky powder from trees #753779

Asked June 03, 2021, 2:30 PM EDT

What is the white powdery sticky substance that seems to be falling from my river birch trees over the last few weeks, and how do I get rid of it? I will wipe off my patio table and it’s covered again within an hour.  I saw online that it could be honeydew from aphids, but I dont see any on the leaves of the trees.

Asked June 03, 2021, 1:31 PM EDT

I have several fruit trees in my yard including apple, pear, peach, and plum. What is the best way to fertilizing them? In the past I have used a root water device that you put pellet in and push in ground to fertilizer them. Is this the best approach or should I be using a surface fertilizer or the stakes you push into the ground? Also what is the best type of fertilizer to use?

Ready to build an Ark... #753755

Asked June 03, 2021, 12:54 PM EDT

There may well be no way to answer this question with any precision, but: our two young oak trees in our back yard -- a bur oak and a chinkapin, both in their fourth summer -- have had a fabulous spring so far. But now, with all the rain we've had, we worry -- partly because I managed to drown a similar pair of young trees about five years ago by over-watering ("You can't over-water anything in this climate", said our neighbors...well, yes, it seems you can...). So far they both appear to be OK, but are they likely in danger from all of the wet weather? We are on former ranchland -- now a suburban subdivision -- two or three miles south of the Travis-Hays county line...

Nothing much to be done about it, I suppose, but still...

Many thanks --

Leland Cypress and lawn ants #753749

Asked June 03, 2021, 12:35 PM EDT

Hello, Is there a good spray fertilizer for Leland Cypress trees? Also, over the past few years our lawn has been ravaged by ant hills all around my property. I want to put down some type of granual. I have used Spectracide Triazicide in the past but was concerned that it may have killed one of my yard trees that we had to cut down. Could you please recommend a good pest control granule product that is effective?

Flower Perennials Under Fruit Trees #753715

Asked June 03, 2021, 10:59 AM EDT

I have an abundance of yarrow & am wondering if they would be okay to transplant under a variety of fruit trees that I have (apple, plum, cherry). I've read that a tall plant underneath will deter pest from crawling onto the tree base because their weight will topple the plant. (True?) Your thoughts/recommendations? THANK YOU! Ruth

Good books for plant choice? #753707

Asked June 03, 2021, 10:35 AM EDT

Hi! I am originally from Arizona and we had a few standards that were always recommended for choosing plants like the booklet called "Landscape Plants for the Arizona Desert" put together by the Arizona Municipal Water Users Association. I was wondering if you could recommend any good sources for the Colorado climate for picking trees, shrubs, plants and vines. I found the https://plantselect.org/ website and will definitely use that as well. Anything you can recommend in the way of books, pamphlets and publications would be very helpful. I do see your publications library and will be looking through those. Thank you!!

shredded balsam trees as mulch/ spruce bud worm #753687

Asked June 03, 2021, 9:12 AM EDT

Have cut/shredded balsam fir trees at my north Minnesota home earlier this year.; many showed disease of spruce bud worm before cutting. Is it unwise to use the mulch around young conifers ( tamarack and spruce ) ? Is there an insecticide safe to place on the mulch that will mitigate risk of spreading spruce bud worm infection?
