    Help Identifying Potential Fire Blight on Apple Tree #885458

    Asked September 16, 2024, 3:34 PM EDT

    Hello,

    I’m hoping to get some help with an apple tree on my property in Oakland County, MI. I’m worried it may have fire blight, but I’m not sure and would love some advice.

    I moved into my home four years ago, and the tree was already on the property. At the time, it had large branches that had been cut off, and this past April (2024), we removed a dead branch ourselves, making sure to sanitize the cutting blade with rubbing alcohol. The trunk has always had a strange appearance since we moved in. In the first year, the tree also had carpenter ants, which we were able to get rid of by spraying.

    This spring, the tree bloomed beautifully and produced apples. However, now there is only one apple left on the tree. I’ve attached images of the tree in September 2024. I’m hoping someone can help me determine if this is fire blight or something else.

    I would love to save the tree, as the apples are delicious, and the blooms are stunning. Any advice or help would be greatly appreciated!

    Thank you!

    Dark dots on hostas #885454

    Asked September 16, 2024, 2:57 PM EDT

    Hello, My dad has a beautiful woodland garden and many of his hostas have small dark dots on top of the leaves. They are raised, not in the leaf so to speak. They feel like running fingers over braille. I’m wondering if you know what they might be, and if they are harmful? The garden is thriving this year with the cooler temps and ample rainfall earlier this season. I should mention most of the hostas with these dots are under silver maple trees.

    Poa Annua #885451

    Asked September 16, 2024, 2:52 PM EDT

    Good afternoon. I'm curious how best to treat post emergent poa annua in a 4 cultivar perennial rye lawn. I'm in the kalamazoo area, soil test is fine, I renovated with good soil/sand, irrigate regularly but based on ETO, treat with ammonium sulfate and natural things like kelp, molasses etc. I didnt blanket spray herbicide or pre-emergent this year but have been spot treating with a speedzone/quonclorac blend. I also have a halosalfuron herbicide for yellow nutsedge. I'm wondering my options short of doing a glyphosate spot treatment. Caveat being I overseeded on August 18th. I've read on the prodiamine label that I need to wait 60 days after overseed before application. I have resisted using tenacity as a blanket spray due to my lawn being all perennial rye, Tenacity tends to damage rye according to its label, however I have come to terms that I may need short term visual damage if mesotrione is the answer. I'm curious what you recommend in terms of what I can do with our average first frost being approx a month out. Thanks so much for your time!
