This area is the high desert, over ft altitude and we get very hot summers and very cold winters similar to the area where rosemary originated. It loves it here. Many of the housing developments in the hills use prostrate rosemary for ground cover on hillsides to prevent erosion and it develops into a very dense mat only about inches high. Iguana, I think you are right about the powdery mildew - note that in my first post I mentioned lack of air circulation and excessive heat.
However I have found that the mild bleach bath does work to destroy the residual unseen spores that remain on seemingly unaffected plant parts.
I also use a very diluted spray of insecticidal soap, water and Listerine or a cheaper generic as recommended by Jerry Baker in one of his print gardening newsletters long before the internet to which I subscribed for years.
The spittle bugs seem to blow in on the wind, and can be an annoying pest but seem to do very little damage to healthy plants Mine are like The Day of The Triffids but I use the homemade spray in a small half-gallon pressure sprayer, followed a short time later with a blast of water and they rarely return. I think rosemary is one of those strange plants that grows for people it likes!
Eastern exposure with only morning sun. Perhaps it was the 3 inches of steer manure I tilled into the soil before I planted them? Anyway, back to topic I don't have the fungus problem, but I do occasionally see the spittle bug evidence. And spiders.
Generally a fungus problem is due to too much water and poor circulation. After the bleach treatment, I'd see about putting it somewhere with a little more breeze. White 'dust' on fresh rosemary. Share More sharing options Followers 0. Recommended Posts.
Curlz Posted January 28, Posted January 28, This is not just a dusty plant--it's something else. Any thoughts??? Link to comment Share on other sites More sharing options Sugarella Posted January 28, Does it actually look like dust? It could be something in your air that's settled. Posted January 28, edited. Typically rosemary will not overwinter in your area. It freezes when temperatures dip below 25 degrees F. But it is an easy herb to grow indoors. Move it inside along with your houseplants in fall.
Put it in a sunny window south facing is ideal and be careful not to overwater it. The roots can easily rot. An occasional misting can help if it gets too dry in your house.

I enjoy Houzz and all of the other virtual forums online. I think it's cool to be able to talk about what we love and help people with their questions.
I think it's important to balance these forums against the fact that by providing all of the detail and our sources, we may also be contributing to the public's ideal of getting free service. In other words, are we our own worst enemy as professionals? Do forums like this discourage people from hiring professionals?

Farmhouse Kitchen Advice Q. We had a similar layout with upper cabinets hanging under an 80's looking soffit.
We knocked out the front of the soffit, and added a thin sheet of wood oak as that was what the cabinets were - basically the same thing you can get at a big box store to place on the end of a row of stock cabinets , trimmed it out, added crown molding, and are now in the process of painting it all white.
I don't have pictures yet, but Kristi at Addicted2Decorating. Of course, hers are a lovely green - mine are white. Hmm -- tiles are glazed I think that's the right way to describe them -- tile body itself is light grey, then has blue glaze on top. Hadn't thought of cutting them -- but sounds like that maybe wouldn't work anyway? In terms of fridge -- what a headache that is. So few choices -- but there are a few. I found exactly one that is And then a few more choices that are Or would you not even notice?
Congrats on the new home. Interesting dining nook at the kitchen window -- really wide windowsill. Grover axel has the right idea for the wall above the wet bar -- but choose overhead cabinets instead of open shelves.
You might take some measurements for a project to resolve your dislike of the red by the window. Perhaps instead of repainting this area, you could cover it, attaching a shelving board flat against the wall there -- think cornice.

This is insane! Sulfuric acid will kill the plant, the powdery mildew, and will scar you if it gets on you. By the way, H2SO4 is sulfuric acid. Use commercial sulfur products to control powdery mildew, not mix it yourself acids. My PhD is in Bio-engineering. H2SO4 IS sulfuric acid. It absolutely will kill your plants AND if it touches your skin or clothing, it will burn them.
Of course, it could be very dilute so it would only hurt a little but…. Suffice it to say, THAT is not what you want. Fisher Scientific. It would be expensive to purchase that way.
Green Cure Fungicide… Good luck with it. I just found mildew on ever leaf of the zucchini I planted two weeks ago. I realize now, as this is my first garden, that I caused it by watering too much. I treated the plants with an over the counter solution and cut away the infected leaves at the base. Now my plants look like stubs with a few new leaves coming in. Was this the right thing to do?
Or should I just dig them up and replant? You did fine Lauren. Keep in mind zucchini and squash will commonly show signs of mildew on the leaves. Removing the culprit is typically a good choice. But with zucchini and squash, most leaves will show this so removing them all will leave your plants looking pretty bare.
As long as you have new growth coming on, you should be fine. Just try to stay on top of the problem. I like the milk and water option. Good luck. Would Korean squash be the answer…? How do I get starts or seeds? Hi Joe, Just read this article and glad I did. I treated all the plants and cut away the really bad foliage. While I was washing the dishes I noticed the palm trees in the back yard have what appears to be PM and some black spots.
Could my plants have gotten it from the trees? My tomato and basil sit under one tree. How do I treat the trees? Do I treat everything back there? Thank you, Candy. Only certain plants are susceptible. And black spots are unrelated. I would treat what you know to be PM where you can and let nature take its course with the rest.
Hi Joe, Can powdery mildew be treated with neem oil?? Someone told me to use this but from what I read it Is for pest not fungus. Pam Texas. While it can help with certain diseases such as black spot on roses and as a deterrent to some pests, mildew is not one of them. Joe, you recommend Neem Oil. I went back and checked, and sure enough you do.
What do I make of this? Hey Tony. Thanks for calling me on this. I am going back to clarify my position on Neem Oil as a control against powdery mildew. I always opt for organic or natural solutions if possible. Thank you for all those great suggestions.
My question is, if I had an outbreak in my garden last year, do I need to treat the soil, prior to planting this year. I lost a lot of plants last year. The best treatment for powdery mildew is stay proactive and start treating the foliage at the first signs of problems or even before it happens is best. Once you have it, all you can do is try to prevent it from spreading. So the earlier you catch it, the better chance you have of keeping it in check. Have you tried Korean squash?
I figured that since it was humid there, it would grow here. It also gets the powdery mildew but continues to produce wonderful crops. It is a type of ball squash and is sweeter than zucchini which I have given up on due to the powdery mildew. I did have some success with some zucchini seeds from a website that is resistant to powdery mildew but it costs so much to mail I decided to get the Korean squash instead.
Make sure you trellis it as it likes to climb. My Korean friend brings it to me from Koreatown, Los Angeles. This milk is concentrated. Do you apply the neem oil directly to all the affected leaves or just on the new ones to stop them from getting the PM? Also, do you need to mix the neem oil with anything, or just use as is? Hi Dionne. Mix the neem oil with water as directed and spray to the entire leaf surface. Neem is one of the best organic controls I know of for controlling disease and acting as a repellent to some insect pests.
Could you give me an idea? Lots of good information, but I grow peas to eat and then turn the leaves and stems into the soil. If the peas get PW should I discard them rather than take the chance of infecting the soil?
Can the spores live in the soil and infect the next crop? I think the milk and baking soda up the ph of the water and powdery mildew likes a more acidic surface. I found using ph up to up the ph of your water to 9. Do not water plants with ph that high just spray the plant. Would like to know what plants you can plant next year in the area where P.
Hi Nancy. Powdery Mildew is most common on certain plants, while others rarely or never get it, even when planted in the same location where your squash for example was ravaged by it the previous year.
So by avoiding the most susceptible edible plants of powdery mildew, you will likely dodge the problem all together, even if planting in the same location the following season. In my garden, the plants most often affected are squash, cucumbers, and cool-season peas. Lots of great ideas on handling PM. I purchased a home with an amazing garden 3 years ago.
This year has been a HUGE struggle. Between PM, black spot, and some insane insect activity I have spent more time trying to save my plants than anything else.
I have come to terms with the loss of most of my new additions and the fact that i got only a few blooms from each plant this season.
Massive cut backs seem to have helped my roses, but the PM persists. I would prefer natural or organic methods, but will resort to chemicals if it means saving the plants. I have such a large area that spraying every plant on a regular basis seems unrealistic.
Its also the end of the season. I plant to cut down as much as possible and remove every last bit of mulch. But what next? Is their a systemic treatment i can douse the soil with? What should I do in the spring? This property lured me in with the beautiful garden, but I am definitely in over my head and need all the help I can get. Hi Eve. My best advise is to stay ahead of the problem.
One of the very best rose growers I know is religious about spraying her plants with Neem Oil mixed with water. She coats her plants with it every week or two. It keeps her roses looking beautiful and disease free, and all organically. To target the powdery mildew specifically, I would stay ahead of the problem by using the 2 parts water to one part milk spray solution. Again, the key is being proactive with this and treating your plants before symptoms become visible.
I read that you can eat the fruit of plants that have PM, but can you wash off the kale and eat that? I pulled up my entire raised bed this morning, which contained a lot of moldy zucchini leaves, and I found this site while looking for a way to treat the soil now in preparation for next spring.
Nothing winters over. Am I correct? Is there a treatment? Hi Andrea. I checked on your question with Dr. Jeff Gillman who conducted the study. It is possible that the fats help this compound to stay on the leaf. When I ran trials we used whole milk, but researchers have found success using a number of other types of milk including skim and powdered. Thanks for this insight on powdery mildew. It appears that it will not be a problem to compost my mildewed plants.
This is yet another case when more is not better. Concentrations above three parts water had adverse side effects. Three parts water to how many parts milk? Hi Carl. Thanks for catching that comment and I apologize for the confusion.
That line was part of an edit that should have been deleted. Stick with the one part milk to two parts water and you will be fine. Thanks again. A portion of my lawn has what I think is powdery mildew.
It is in the shade and only some of the blades of grass have a while tinge to them.. How would I treat this? A great resource for this or other plant-related problems is your local county extension office. You can take a sample by be sure to include healthy and diseased parts and they can analyze the issue and diagnose the problem to suggest the best solution. Hi Cyndi. The following reply is directly from Dr. I have been fighting powdery mildew this season.
I got it in my vegetable and herb garden. I sprayed my squash and cucumbers with the baking soda, dish soap and water solution. And for my dillweed, I just cut it out and got rid of it. I had a few volunteer dill plants come up. Well, they are getting infected! It has been about a month since I cut out the infected dill. And our weather has been mild with normal rain. Why am I getting the mildew back on the new dill?
Is there anyway to treat the bed to kill all the spores? E is used primarily as a pest control, since the fine particles are sharp and desiccate the tissue of soft bodied pests such as snails and slugs.
E has any properties that would fight powdery mildew. Joe, you have a great site. I read all your info about milk and PM. I have a well established infection of PM on a number of my Hibiscus in my greenhouse. What is your suggestion?
The PM is on the trunk and stems. Thanks, John PS I hard cut back hard each fall so there are few leaves to contend with. Hi John. I wish I could give you more concrete help here. I would continue to spray exposed areas with this periodically and see if we can keep it from spreading. Time will tell.
