Hi Denise, My peonies are losing color. One of the three groups didn’t materialize at all in the spring. Then one of the other plants sprouted, produced one bloom, and then promptly withered away. My third plant is now on the verge of dying. My granny owned these plants. Are they permanently lost?
We recently noticed the mulch in this same bed being entirely turned when we got up. The bed appeared to have been flipped and scraped. Is this the work of raccoons, skunks, or might it be a turkey?
To Nikki: The peonies come first. Your peonies seem to have a fungus-related illness. Peonies are commonly infected by the fungus known as botrytis blight. It can cause later spring larger buds to turn brown and fresh spring stems to abruptly droop and fall over.
According to Virginia Tech extension plant pathologist Mary Ann Hansen, big, irregular dark brown blotches and large, fluffy masses of gray-brown fungus spores can occasionally be seen on the leaves. In more severe situations, botrytis can also result in crown and root rot.
But there is a cure, according to Mike Ecker, the Dawes Arboretum’s director of horticulture.
“Use a fungicide with a botrytis label on peonies in the spring. Some are also appropriate for fall applications. After that, remove and clean up all plant debris.
According to Brad Kiger, the Franklin County wildlife officer for the Ohio Department of Natural Resources, a turkey is most definitely not to blame for the oddly changed mulch.
“They are currently highly active, which is a major problem at this time of year. They destroy gardens and lawns in search of grubs.
Hi Denise, The plant in the attached photo is one that I’ve been attempting to identify for a year.
With the winter, the plant withers away to the ground. Every spring, it returns, and if I don’t cut it back, it will cover the area around the front entrance. It has huge leaves, a lovely purple blossom, and the scent of violets.
It has already begun to spread everywhere. We adore it, but how can we preserve it in a location?
Charlie, please: Your plant is a passionflower vine, which is unquestionably a hardy species in our environment. However, as you might have imagined, keeping it under control and contained can be a full-time job.
If you intend to maintain your vine and merely wish to contain it, “Garden consultant Deb Knapke advised digging up and removing the seedlings from any areas where you don’t want them to grow.
As soon as fruit starts to form on the vine, pluck it and throw it away to slow growth.”
Keep it from going to seed.
Be aware that you will need to carefully remove seedlings in places where the plant is undesirable for years.
Hi Denise, My ash tree is reportedly infested with clearwing borers. Can you describe these borers and the best way to get rid of them from the tree? Will the tree be felled?
Hi Helen, Ash, dogwood, viburnum, birch, and pine are just a few of the trees and shrubs that clearwing borers eat. They are native borer species. According to Chris Ahlum, an arborist of Ahlum & Arbor in Hilliard, native borers normally only attack dead, dying, recently planted, or stressed trees, unlike emerald ash borers, which attack any ash tree. They will probably cause the tree to die if not handled.
“Imidacloprid (trunk injections) does not work against clearwing borers if you have been treating your trees for the emerald ash borer; however, TREE-age will work against both borers.
Although a foliar spray can be used to treat them as well, Ahlum suggests a trunk injection.
Hi Denise, Two crab apple trees that we own have very few leaves and a black scab. Please let me know what the best plan of action is for treating this.
Greetings, Ray and Connie. The cold, damp spring has made apple scab quite common this year.
“According to Ahlum, this fungus typically infects trees in the spring but only produces leaf spots and leaf droppage in the summer.
Once the fungus is on the leaves, there is little that can be done to treat or remove it. However, the fungus can be prevented and controlled by using a series of three fungicide applications in the spring, from early April through May.
Rake up and get rid of all the fruit and leaves that have fallen from the tree till then. According to Ohio State University Extension, the fungus can survive the winter on the fallen leaves, and removing the leaves lowers the amount of spores that could restart the disease cycle in the spring.
Hi Denise, We used to have a lovely stand of hollyhocks, but this year they started to have issues. The tops of the leaves have reddish-brown patches, while the bottoms of the leaves have bumps that match the spots. The plants don’t produce as many flowers as they once did. I searched for insects but found none, despite spraying with Sevin and Bt, which had no effect. Can you offer me a diagnosis and a treatment?
Hello, Bill It’s challenging to identify your plants without seeing them, but hollyhock rust is most likely the cause. It is the most prevalent hollyhock issue, and the fungus that causes it. Older foliage is immediately killed off as it quickly spreads from leaf to leaf.
To manage it, “As the fungus overwinter in plant detritus, Knapke advised cleaning up and getting rid of all the old leaves and stems. Then, you can either get rid of the plants and think about “To stop further outbreaks, plant something else there that is not a member of the Malvae or Malvaceae family.
According to Virginia Tech Cooperative Extension, the plants may also be sprayed with a fungicide comprising chlorothalonil, mancozeb, trifloxystrobin, or myclobutanil at the first indication of disease.

How can a peony that is dying be saved?
Botrytis blight, also known as gray mold, causes flowers, leaves, and buds to drop off too soon as well as cause bud rot, wilted shoots, and foliage. High humidity promotes the spread of this fungus, which results in masses of spores that range in color from brown to gray on the peony. Plants with the infection experience twig die-back, flower buds that do not open, and wilting and dropping of their leaves from the twigs. Infected plants won’t suffer significant harm if the fungus is kept at bay with proper maintenance and cultural control. In humid, damp weather, regularly check the peonies for fungal illnesses. Regularly remove any plant debris that has fallen to the ground beneath the peony and dispose of it properly. Immediately remove from the peony any plant tissue that is dead, sick, or infected. Early spring applications of copper sulfate will aid in botrytis blight defense for the peony. However, don’t use it on shoots that are shorter than 6 inches.
Why are the leaves on my peony wilting?
The fungus Botrytis paeoniae, which is closely related to Botrytis cinerea, which causes grey mold on other plants, is responsible for peony wilt.
In the afflicted plant material, it creates tiny, black resting structures called sclerotia that fall to the ground. These have the potential to stay latent in the soil and spread the illness from year to year.
The springtime germination of the sclerotia causes a large amount of airborne spores to be released, which then spread to the leaves, stems, and flower buds. The fuzzy gray growth also creates more airborne spores, which spreads the illness even more.
What does peony botrytis look like?
Peony young shoots are covered in a thick, velvety gray mold by the Botrytis fungus. Very young shoots may become blighted and turn black early on. Bud blast and flower blight may also be caused by botrytis growing on developing floral components. Buds that are infected may enlarge before dying and never opening.
When should fungicide be used to peonies?
Employ a fungicide. When the plant’s young tips emerge from the soil, spray it with a fungicide. Apply again after two weeks, then every 14 days after that until mid-June.
What can you do to revive a peony?
You don’t have to let your proud bouquet slink quietly into the dark night without a fight. Your gorgeous flowers can recover with some quick emergency life-saving “medical care” (in a nice way, not in a zombie way). We’ll assist you in bringing the life back into your dying flowers by giving them some resurrection treatment.
Clean Your “Operating Room
Make sure your vase is spotless and free of any risks before tackling the root of the issue. Give it a few minutes to settle after adding some hot water and dish soap. Your vase should be prepared for its part in the rebirth after a thorough rinse.
Cut the Stems
Simply said, flowers aren’t getting enough water, which is why they start to wilt. Even if there is enough of water in the vase, this can still occur, mainly when there is no route for water to enter the stem itself. This is so because when a stem is severed, the tissue that carries water through the flower starts to die. This process starts at the incision and gets worse every day.
It’s crucial to clip the stems of your flowers in order to avoid the blockage of dead tissue. Use a non-serrated knife or pair of scissors to cut at a spot that is about an inch higher than the object’s present base. In order to improve the surface area for absorption and prevent the stem base from lying flat at the bottom of the vase, it is essential to cut the stems at a 45-degree angle.
Every time you replace the water in your Bouqs, trim the stems at a 45-degree angle as a best practice.
Crush the Stems
You might need to take extra precautions if your garden contains water-loving flowers like hydrangeas or irises. Crush the stems after removing them. Even though it seems counterintuitive, shattering the stems really helps the flowers’ health. The stems’ capacity to absorb water is increased by crushing them, which also enhances their likelihood of rehydrating.
Add Bleach to the Water to Kill Bacteria
No, you shouldn’t put your flowers in a bucket of bleach to accomplish this. But in little doses, bleach can be really helpful. A bacterial infection in the “open wound where it has been previously sliced” is one reason why water cannot pass through the plants.
When adding sugar or plant food, which bacteria love, this might become especially common. You just need to use a tiny bit of bleach—one teaspoon to a quart—to protect your blossom against illness and harmful germs. Since it is thoroughly diluted, your blooms won’t be harmed.
Add Sugar or Plant Food to the Water
Sugar is the adrenaline boost that gives your flower’s critical organs the emergency blood trickle they need to survive. For this reason, plant food already contains sugar; if you don’t have any packages of it laying around, regular sugar will work just as well. It should be sufficient to add one teaspoon of sugar or plant food to a quart of water to revive your flowers and restore their vibrant appearance.
After two or three hours, if this hasn’t helped, add one more teaspoon of sugar (first dissolved in warm water).
Trim Away Dead or Dying Foliage
Amputation is your sole option if your flower isn’t receiving enough food or water to keep all of its parts healthy. Cutting or pulling off these leaves and blossoms guarantees that your flower saves the energy it has for its healthy stems. Dead and dying leaves and blooms deplete important resources from viable blooms.
Keep Them Cool
Like many fresh items, keeping flowers cold and away from direct heat will help them stay fresher for longer. You can even store them overnight in a refrigerator if you live in an exceptionally warm area for maximum preservation benefits.
Since cut flowers cannot photosynthesize, direct sunshine is not beneficial to them. In reality, those flowering beauties can pass away more quickly in direct sunshine. Therefore, remove them from the windowsill or table by the window so they can live longer.
What is used as a botrytis spray?
- Put a lot of organic mulch or compost under the plants. Mulches will stop the fungi from splashing back up onto the foliage and flowers.
- Use a soaker hose or water in the early morning to give plants time to dry out over the day.
- Avoid composting sick plant leaves or stems, and in the fall, carefully clean garden areas to lessen the number of places where fungal spores can overwinter.
- Fungicides made of copper soap will aid by shielding plants from disease spores. Apply as soon as flowering begins and then every 7 to 10 days till harvest. When a prolonged period of cool, rainy weather is predicted by the weather, fungicidal sprays are highly recommended.
- Use SERENADE Garden to safely cure the majority of fungal illnesses, such as Botrytis blight. A patented strain of Bacillus subtilis that is authorized for use in organic production is used in this broad spectrum bio-fungicide. The best part is that SERENADE is absolutely non-toxic to helpful insects like honey bees.
- The biological fungicide Mycostop, which is permitted for organic usage, has demonstrated disease control. Spray vulnerable foliage, flowers, and fruits directly (5 gm/50 liters of water) till the point of run-off. Apply as needed, or as often as necessary, depending on the disease’s pressure.
- A proprietary potassium bicarbonate mixture found in Green Cure Fungicide, which is frequently found in food goods, kills several plant diseases on contact and offers residual protection for up to two weeks. Apply 1-2 Tbsp per gallon of water to all exposed surfaces of the plant at the first sign of disease. Repeat for maximum protection every 1-2 weeks until the risk of illness development is eliminated.
How can I eradicate botrytis?
Starting with adequate cleanliness will help with botrytis blight treatment. Debris that falls to the ground beneath the plant should be picked up and destroyed. This comprises fruit, flowers, buds, leaves, and twigs. Remove and destroy any contaminated plant parts. To stop the disease from spreading, disinfect pruners between cuttings with a 10% solution of household bleach. If burning is not permitted where you live, destroy contaminated plant material by burning it or by burying it under at least a foot (31 cm) of earth.
Natural illness in healthy plants is rare. As much as possible, stay away from stressful growing situations. Ensure that the plant receives the right amount of water, fertilizer, and sunlight. Water the soil directly to keep the foliage as dry as possible. Pruning should be done as needed to promote optimal airflow.
Good hygiene and better growing circumstances can help you prevent gray mold to some extent, but since the spores disperse widely on the wind, full control is challenging. Fungicides can aid in minimizing the harm done to priceless landscape plants. Select a product that is labeled for use on the particular plant type you are treating and for protection against botrytis blight. Store the product in its original container and out of the reach of children. Carefully follow the label directions.
