    Every time I do a research into my garden issues, I end up finding the answer and the solution to the problem on this channel. Jason, thank you so much for sharing your expertise for free ))

    The 4th of July I was at my best friend's house where she is just learning to become a gardener. She told me to come look at her rose bushes which were "filled with ladybugs." My first thought was, oh no she must have aphids but when I looked they were covered with Japanese beetles! As I'm trying to Google what would be safe to use on them she grabbed her spray bottle of water and peppermint essential oil and sprayed the plants. Not only did they disappear but several hours later they were still gone. Just a thought.
  • Hello Jason; for sure so many of us are grateful for your extensive information. I keep all your videos not only because they are of great help should I have problems, but because they are all so interesting and I enjoyed them. As you know I just have a small garden which is more than plenty for me, and I adore my roses 🌹. Thank you 🌹🌺🌸
  • Thank you Jason. I will be ready this rose season. Very appreciated to get clear information.
  • @donp1088
    What an amazing job you’ve done in explaining and describing this pest and things we need to know to fight the fight for our garden! Thank you, so much…👍❣️
  • @LaMarAzura
    Thanks!!! new viewer. Very much to the point of subjects!!! Many other garden youtubers talk too much unessential to the subjects. I click off less than a minute viewing them. Thanks for the all educational points you put out. and I love your garden background too. looks so pristine!!
  • @alliehartom5978
    I just found these on one of my plants outside and lo and behold your channel pops up in my recommendations. Thank you so much!
  • @cedarwriter26
    This is great! This is more detailed in solutions than I've seen in rose books. I have a container garden of roses, geraniums, hydrangeas and more, so when they find me, they party.
  • @dennistaft7868
    Once again, Jason you come though with the info we need. I get these but not in huge numbers. I would like to keep it that way so I'm going to follow your advice.
  • @nicicorps9683
    Thank u sooo much for this. Last year we had a bad invasion and have been looking everywhere on the internet how to deal with the problem. Finally, after your video, Feel armed and ready to get 'em!!!!!
  • @yeomjiwon
    I saw damaged roses a few days ago. It is a good review. Thank you!
  • Thanks. As always your information is clear and scientifically based. I used to have only once blooming heirloom roses that finish before JB season, but decided that they weren’t going to win and have added others during the past few years. They also LOVE cuphea and a few others. You have provided new tools in my armament. Kathleen, 5b

  • @Jennifer-qo4kz
    So glad I came across your video It’s gonna be so helpful because I’m starting to see a lot of them and they are wreaking havoc on my zinnias 🤨 Thank you 👍🏻
  • @traceye.6428
    This info is so helpful, thank you kindly. I have been very disheartened, so good to know about these methods. Btw, I like the fact that you are wearing your frayed sleeve jacket. A true gardener in his working garb! 😁
  • @jenjens916
    Thank you this was so informative because I see now the damage going on with my plants. My hibiscus plant is like a skeleton when I checked yesterday. I will be on it, now I know what's attacking my plants. Thank you again, first time finding this channel.
  • @tarar6926
    Thank you so much. I think this explains both the brown patches in my lawn and the holes in my grape leaves! Thank you!
  • @Junkinsally
    Thanks so much! Your videos are always so informative.
  • @xtina4968
    Hi. From Minnesota. Yes Japanese beetles I have great amount of them in my back yard. Thank you for sharing your great knowledge
  • Thank you for the finite explanation of who the Japanese Beetle is and how they make their way onto our plants, and now armed with new information, we can redirect them. =)
