Recipe: 1 TB per gallon for prevention, 2 TB for accute condition. Dish soap (I use castile--Dr. Bronners) to aid adhesion; helps it stick to foliage. Early morning application, spray once werkly.
I'm glad to know what to do about the powdery mildew. My second biggest problem in the garden is white flies. Insecticidal soap helps, but it is a never ending battle.
I needed to know this months ago. But sometimes experience is the best teacher! Thanks for sharing Luke. At least I won’t give up on cucurbits just yet 😂. I’ll utilize this for next years garden.
I lost all of my cukes and squash to powdery mildew this summer. I did not know what it was or how to treat it. I had to tear everything out of my garden.😢Saw the squirrel at 9:44 under the fence. I am so grateful for this informative video!
Thank you. Powdery mildew just killed my cantaloupes. I tried the milk and water, and it didn't work, I tried the baking soda and water, it didn't work,. So PREVENTATIVE measures is the best way to go. Thank you. You and this channel have truly been a blessing.✝️❤️🌍
@@gi295 yes , in some instances He will. But He gave us a brain to use too, and wisdom , if you belong to HIM. And He expects us to use them.God Bless you. You know the Lord warned there would be mockers and scoffers in the last days , and men would be lovers of themselves more than God. You are only confirming more , we are in the end of the end of time . I pray the Lord has mercy on your soul.✝️❤️🌍
Last year, I sprayed a milk/water mixture after each rain since I knew the high humidity (I'm in Georgia, zone 7) was a perfect situation for powdery mildew to grow. This worked very well as a preventive. Now to figure out how to keep Squash Vine Borers away.
Greetings from arizona! Now that we finally been getting rain the powdery mildew is creeping up on us. Great timing with this video. Thanks for all the tips and tricks brother! Cheers 🥂
The Dawn acts as a surfactant and breaks up the surface tension of the water... which keeps it from beading up and rolling off the leaves! Also great for helping home made weed killer stick to the plants and even soak into the ground down to the roots. Good stuff!
Thanks for the great video! Here in AZ we have monsoon rain almost daily from early July until September. That is our mildew season. I've never tried to control it, although last year I set in a second planting from seed in Mid-Aug and that crop did better than the spring crop. I'll give your solution a try this season.
Thanks for the video. Could you do something on distinguishing powdery mildew (or blight for that matter) from other things? I don't actually know what the visual differences are compared to things like the leaves getting old or a little heat burned so they crinkle and get a little brown... Thanks!
I find bacon grease to be effective at getting rid of pests like locusts. Apply it to all your surfaces & it will make them feel uncomfortable & move to other pastures where they are welcome. It’s also great to lube door hinges & keep garden tools like rakes, axes, shovels, hatchets etc from rusting. It also works on zombies that take over Europe in movies but I can't remember the movie name I saw that piece of movie trivia in so don't bother asking me about the movie where zombies take over Europe & it is solved with bacon grease. You only need a drop!
Thanks again, Luke. Great video; I like the old "Grow big or go home" video wrap-up. Grow Bigger is next level as far as I can tell. Great job to the team @ MIgardener.
Thank you so much for this video. I do have powdery mildew on my zucchini leaves. I found information that said to spray a milk solution every two days and baking soda every three. I did cut many of my leaves off and compost them as the plants needed trimming anyway. It has rained the last two days, so I haven’t sprayed at all. I will be going out this morning to check on the status of the plants. I was spraying the underside which, because of you, I will not be doing anymore. Take care.
This is not related to your video but I had a crazy, wild, vivid dream last night about getting to hang out with you. We shared a wonderful hug and our families spent an afternoon together at your house (which wasn't actually your house, lol, it was something my mind had imagined.) You were showing me your garden and suddenly a flood came! Which might have been a good thing because there was a 20 foot snake in your garden and you couldn't believe it! The mind works in mysterious ways, not sure what was going on in my subconscious to bring this dream about but I felt like I actually got to meet you, and I was thankful for that. I wasn't sure why I was so fortunate to spend my afternoon with such a wonderful person. I had to come to the computer and tell you my dream before it left me forever. Love ya Luke and I hope you and your family have a wonderful weekend!
I found a video of yours that indicates that you shouldn't spray until you see the issue spreading. It was the video where you addressed the different products to combat fungal issues. One being copper fungicide and also the baking soda mix. Then I found this video. I always figured preventive measures were best but the other video had me wondering.
I've had luck with digging up perennial plants and fixing the drainage issues. I spray with milk and water as a preventative It works with cucumbers too.
I fought this all summer. Need to do a real good fall cleanup. It would have helped tons if my neighbor took care of his garden. Im sure the spores continually blew over.
Amy: Your interpretation is certainly more encouraging than mine, so I will try to keep it mind. I just wasn’t familiar with it. I believe community gardens are an excellent idea however I haven’t heard of any in my area.
I'd be very careful with that dosage and test a leaf or two and wait 48hrs before spraying everything. I've seen plants burn at 1 tablespoon per gallon even when spraying early in the AM. I keep it to 1tsp. Per gallon with 1tablespoon of full fat milk per gallon . You will notice the milk will make the leaves a bit shiny. You can test the pH of you mix using pH drops. 9-10 pH will do. Best thing is to have healthy vigorous organically grown plants to start but yea you'll be in tough if the nightly humidity rises and temperatures start dropping below 10 degrees celcious and oh yea don't overwater late in the season use minimal water and let the soil dry before watering again. 😄
That’s my biggest problem in the garden! I thought it was in the air! And that when you water from the above, it sticks to the leaves… Huh! Thanks for the fantastic info!
Good info! Thanks!! I think the pumpkin is done in though. I read the spores were underneath as well and it one reason I didn’t treat as that’s a Pain to do especially now they are crowded. Don’t think they will make Halloween. Maybe if I wax the pumpkins. They were so vigorous a week ago, not now. The Fall rain started and fog/dew from cool nights and it appeared. This is on a pile of dirt surrounded by grass. The dirt was delivered and wasn’t to excited about it because it has a lot of clay so we just threw seeds at it and we get what we get. I had to heavily fence it because of deer. I couldn’t get inside and just left it and tomatoes, peppers, Brussels, watermelon do their thing. What I noticed was it wasn’t affected by any blights as early or at all like regular garden-those tomatoes were hit bad a month ago, but it happens every year in august as the plants are just done. Well the circle experiment garden was fine till last week. Those pumpkin leaves are a big fuzzy attractor.
Have used baking soda, a little soap forever. Found that adding apple cider vinegar as a major ingredient made the difference. But also cutting back leaves as much as possible has been the win for me this year. Thanks.... yup WEAK plants take on the fungus first. Have been getting rid of these plants more aggressively this year.. WIN!
My zukes and cukes are suffering and I use this baking soda spray most evenings. It’s helping a bit. I wish I would have know I can use this earlier in the season as a preventative. I guess next year.
Luke, I have personally had better results using potassium bicarbonate and it leaves me wondering. Is there really any benefit to use potassium bicarbonate vs sodium bicarbonate? My initial thought was sodium would possibly build up salts in the soil. But on the other hand potassium could be beneficial to the soil. Am completely wrong in this thinking?
Potassium bicarbonate is better in my opinion. Not too much difference tho in my experience since you don’t use very much. Id be worried more about pH than salt build up
Already lost my fall cucumbers because of random frost night, did use veil though. Will see how fall garlics end up forming if theres 30 days needed for growth and frost night are so random. Not too easy gardening here in Finland at 60° north either O_o
My cucumber and squash leaves were covered! They were basically covered over night and it got way ahead of me. My first garden in 41 years, and I've never seen this before in my garden years ago. I tried baking soda, but it was just too late and I gave up. I will be on top of it next year!
I love your channel. As a novice gardener I’m getting very useful info from you. Thank you for this vid. I’ll keep this in mind for next year for sure because my cukes and zucchini are done for at this point. Can you say where you purchased the container/sprayer? I want one!
You never mentioned Downey mildew. Will this application will work for that too? It usually comes along with powdery mildew. Downey mildew is harder to combat once you have it on your plants, so preventative is the only way to go. This year has been a historic fungus year in our garden. SO strange. It's literally on everything. Even our peppers. We've NEVER seen this big of an outbreak before. I'm so burned out from spraying, and am out of copper fungicide. In a normal year, I would have to buy only 1 bottle. This year, 2 was needed. Thanks for a cheap alternative to try out, Luke. I pray it's as magical as my copper spray. 🙏
What if you spray like you explained and it rains the next day ? Should you spray again or wait a week . I’m past preventative it’s on all my cucumbers
Luke, As a professional aquarist, I learned decades ago that it is far easier, & better for the fish, to opt for species that adapt well to your water parameters than try to adjust the parameters to suit the fish. I tend to choose garden denizens much the same as I choose fish. Which brings me to my question. My native VA soil is predominantly acid clay, ergo, most of my plants are acid loving/tolerant varieties. You said that, to treat downy mildew, you raise or LOWER the pH on the leaves just a bit, therefore, it should be possible to also use vinegar as a treatment, correct? If using household vinegar, what would be the measurement per gallon of water? Thank you in advance for your advice! 😊
Hi Terri! I actually just watched another video Luke did 2 years ago called "My Mid Summer Spraying Regiment for Blight, Powdery Mildew, and Pests." In this video mentioned using apple cider vinegar as a way to treat an acute case of Powdery Mildew instead of as a preventative measure. He suggested about 2 tablespoons of vinegar in a spray bottle and fill the rest with water. Good luck!
Another great one. Only place I go for straight shooting on our gardening woes. Can plastic or wood chip mulch help to stave it off, too, by reducing soil contact?
Last week I was dealing with powdery mildew and white flies. I did a solution with 2 gallons of water. 1 tablespoon of baking soda tiny squirt of dawn and half a teaspoon of neem oil. I sprayed around 7:30pm and within two days they were all gone.... and so wer all the leaves 🍃 😢 😞 do not mix your ingredients people. Stick to the recipe.
I agree with a previous comment. “Grow big at home” is a much better slogan, “go home” says give up and annoys me every time I hear it. Thank you for this video as I’m fighting pm too. I will be sure to start the preventative approach as you advise next year. Love your advise, just hate part of you slogan.
It’s a play on “go big or go home” which means “if you are going to do something, then put all your effort into it.” I think your suggestion is problematic too. What about those gardeners who don’t garden where they live? Many people only have access to a community garden. Do you want him to not provide content that those community gardeners find helpful?
Perfect timing! Definitely going to give this a try. One quick question...my garden does get some overspray from our underground sprinkling. Should I apply this more than once per week?
I’m in north Florida. Raining about every day now. Should I still wait for one week spraying even after the rain ? Can you spray in the evening instead of morning?
Baking soda and soap fried my cucumber leaves. I should have tested first. Maybe because the sun was so strong. I don't know. I sprayed it on. It was fine. The next day, leaves were all dead and white. I'm trying to nurse it back. But it's probably dead.
Excellent information in this video! Will this work the same way in a greenhouse? Also, should I be removing leaves that are already infected with powdery mildew? Thanks.
I will NOT be using dish soap. I will find an alternative to Dawn dish soap (someone else suggested castile: Dr. B's.. will consider - thanks for the great ideas, though. Does anyone consider anything that can actually be eaten to combine w/bs to help with adhesion issue? I'm in OH & very new to gardening so I appreciate your comparisons of different zones/temps & detailed rambling more than you know, thanks
Can you talk about downy mildew? Once the temps cooled down, all my basils were affected. I saw in a different video that it’s just all over in the air in the East Coast. The only solutions offered were getting resistant cultivars and bringing the plants in on humid nights. Any help would be appreciated!
Luke thank you for all your videos. I have the old vine tomatoes coming in strong and my father is extremely excited about them. I have a question though, would that work for indoors as well, or this something for just outdoors? Last winter I was growing pumpkins indoors and I got PMD. Cheers!
Ugh! I wish you posted this video sooner!!! My cukes and squash are almost toast! Neem oil hasn't kept up with it. Will post back if this works. Also, there's white fuzzy mildew on the underside of my squash leaves... soooo yeaaah
Hello! Is this a new approach for you? A couple years ago you mentioned not to do anything with the plants unless 50% affected as it stresses the plant? Or is that just for pests? Thankyou I appreciate your experience.
