Burning Bush #751057

Asked May 20, 2021, 12:04 PM EDT

I have 8 t0 10 burning bushes that are probably about 12 years old. The leaves turned brown, but did not drop off last winter. They are not leafing this year. A couple of them have gotten some leaves, but not full as normally happens this time of year. Most of the others have some greenery coming up from the base. Do you suggest cutting them back to near ground level, wait and see what happens, dig them out and start over or some other option?

Apple and Fruit Trees #751050

Asked May 20, 2021, 11:51 AM EDT

Hi, my name is Deb and I live in Aurora, Colorado. We have 1 apple and 1 peach tree and have experienced them being consumed with bugs inside when we finally pick them. We are wondering if their is a simple way, as we are truly amateurs when it comes to this, but would like to enjoy our fruits. 1. Is there a good time to treat the trees once they have blooms? 2. We have purchased Bonide Eight Yard and Garden but I was told to not use it until there are bugs. I see they also have a Fruit and Tree Guard which is for the fruit after it has produced. 3. Most importantly, is there a proactive preventive treatment that can be used?

Yellowing leaves on Red Twig Cornus sericea #751045

Asked May 20, 2021, 11:38 AM EDT

I planted my Red Twig, purchased from a reputable nursery, in March 2021, with some all around fertilizer mixed into the dirt/landscaping mix at the bottom of the planting hole. When I took it out of the pot, all the pot dirt fell off; it was planted as bare root, for all practical purposes. I located it in my sunny, rain garden location. It thrived. Although we have had a dry spring in Portland, I have watered well and it has continued to thrive, or so I have thought. However, for the last couple of weeks, the leaves are turning from green to lighter and lighter yellow-green, until now the impression as I look at the tree is that it has yellow leaves. Also, what I took to be buds forming now look all dried up. Is something wrong with my tree? Thank you for your help. Cheri

garlic weed control and disposal #751025

Asked May 20, 2021, 10:36 AM EDT

We recently discovered what this noxious weed is and our property has been invaded with a great deal of it. I'm pulling it up by hand and bagging it. Are there any programs, school or otherwise, of which you are aware that can assist? Some of it is located among stinging nettles - ugh. We're older and I'm concerned it's going to go to seed before we slowpokes can eradicate it. Also, now what - with the bags full? We're told it is toxic to soil so not to compost it. Burning it presents a carbon issue for us.Thank you.

Young oak leaf hydrangea #751006

Asked May 20, 2021, 9:32 AM EDT

We have three Snow Queen oak leaf hydrangea that were planted last May. Do they need netting to protect from cicadas? We covered them a week ago , but I am concerned about having the netting on will harm the plant for other reasons. What is the best call and how long do you keep the netting on, if it should be on?

Question about wounded tree #750993

Asked May 20, 2021, 7:37 AM EDT

Hello, I recently planted a 6 foot tall sycamore tree in my yard. Tonight I accidentally hit the base with a weed whacker (stupid stupid stupid mistake). There is still some bark intact from ground up, but about 4/5 of the truck is stripped in about a one inch band. I have wrapped it in a wet paper towel and secured it with packing tape. What do you recommend I do now/next? I looked at Tree Kote products but wasn't sure that was the correct solution. I want to try and save the tree and am asking for any help you can provide. Thank you in advance for your time.

American Sweetgum (Liquidambar) Tree Removal #750989

Asked May 20, 2021, 12:16 AM EDT

Hello - thank you in advance for your assistance! We have three Sweetgum trees that are starting to wreak havoc on some pipes leading away from our home due their expansive roots. As a result, we have been advised by our plumber that they should be removed, or else will continue to to cause issues. Thus, I had a couple of questions regarding their removal: 1. One arborist suggested that after cutting down the trees, we need to further "poison" the stump to prevent the roots from continuing to cause issues. My question is thus would those roots continue to grow/expand, even after the tree has been cut down? 2. He wanted to use Round-Up to "poison", but we are initially against due to the environmental concerns. He did however suggest that a combination of vinegar and salt could be equally effective. Would that mixture work? 3. If you had any other suggestions / points to consider with respect to removing this type of tree - please let me know. Thank you again! -Seth Philip

How to control weeds in my lawn. #750934

Asked May 19, 2021, 5:18 PM EDT

Please help. I replaced my yard by removing old sod and dirt underneath last year. I replaces it with compost and Colorado Blue (supposed to be drought resistant compared to Kentucky Bluegrass), from Green Valley Turf Company and I pulled weeds last year by hand and applied weed and feed in the fall. With all of the rain my grass is growing fast, iI try to follow the mow no more than 1/3 rule. I didn't get pre-emergent herbicides on the grass. I just read that on your site. So, I need a post emergent weed killer. I don't think it needs fertilizer because it is growing super fast and lush green. I haven't watered at all, yet. I have a dog. So, I'm not fond of harsh chemicals but weeds are coming back. I'm especially concerned about controlling the morning glory or bind weed that I dug down almost a foot last year to remove. It is coming back- no blooms yet. I have been battling that morning glory/bindweed stuff for 20 years now. And replaced my yard twice. I can't afford to replace it again and need to learn how to control my yard. I also have some thistle, dandelions and other weeds. Should I just pull all of them out or tis there a bio friendly weed/pest killer? If the bio friendly one isn't strong enough I will use chemicals or whatever is needed to control the morning glory/bindweed stuff. I've been aerating by hand (2 hole step aerator core tool). I'll include photos of what I call the morning glory/bindweed stuff and you could please let me know if that is what it is called.

Rust on Knockout Roses? #750933

Asked May 19, 2021, 5:17 PM EDT

The pictures are of a 10-year-old red knockout rose hedge in Comus (upper Montgomery County, MD). Tops of leaves show brown spotting; the undersides of leaves and a few rachises are covered with spots of very fine orange dusty-material. There are some smooth-edged medium to large sized inter-veinal holes in leaves associated with the brown spotting. Background: 1) Site gets full sun from sunrise to about 4pm; 2) Orange spots were first noticed around the beginning of May and weather has been unusually cool with occasional misty showers; 3) pictures were taken late afternoon on 5/19/21. Looks all the world like Phragmidium rose rust to me, but when I asked this question at the Ask a Master Gardener Training this week Dave Clement said rose rust is limited to the west coast and I should submit the information to extension for review. Here it is.

are those snake worms in my compost bin? #750923

Asked May 19, 2021, 4:30 PM EDT

My backyard compost bin is teeming with worms. I am unsure whether they are harmless earthworms or invasive snake worms. I am afraid to spread any of this compost in my garden until I find out. If they are snake worms, can you tell me what to do about them? I am attaching two photos taken about 12 days apart. I also have a video that I could send you, since I believe one way to identify them is by how they move.

How to wataer a large cottonless cottonwood #750915

Asked May 19, 2021, 3:48 PM EDT

I need to water my 20 year old cottonless cottonwood tree with a BUNCH of water. I have been putting the sprinkler on at its base and sprinkling a 50 foot diameter around the tree but this has not worked. It lost a significant amount of branches (lower down thank goodness) this winter despite watering several times for 8 hours at a time during the winter. Its roots are on the surface as much as 50 feet from the trunk. Can I just put a massive amount of water closer to the trunk and have better success? Thanks.

Japanese Upright Yew sudden brown needles #750907

Asked May 19, 2021, 3:19 PM EDT

Just within the past week my yew in the backyard developed a lot of brown needles on specific branches. When I looked at those branch's wood I noticed this white stuff on them. Possible fungus or scale? Not sure what it is, and then how to best treat it. Last month I cut out another brown branch but assumed (probably incorrectly) that it was from the harsh February cold. The yew is way away from any sort of street salt. I am attaching 1) a picture of the brown needles and 2) a picture of the white stuff on the branches. I live in St. Louis Park in Hennepin County.
