Dear members,
Most of my roses have been heavily attacked with rust in the gray May. I have removed the leaves and cut the canes back; added fertilizer, epson salt; and hope to get new growth. Now we are having sunny days and I pray all will be well. My new Dave Bang roses had no disease! He is a young Breeder from San Jose. I hope to get him to speak next year. His roses are available from KandM nursery. You can view his roses there or on YouTube.
On June 8 you have an opportunity to see an amazing native garden so see the items below for information.. Also a great chance to meet Grace Paulson of Grace Rose Farm at our June 15th meeting. She sells cut flowers and roses out of Grace Rose Farm in Somis. I hope in the future to have an opportunity for us to visit the Farm. Happy rose growing this summer and as we don’t meet in July or August, I will see you in September for a talk by Kathy Monge about disease and bugs on roses!

Grace Poulson Grace Rose Farms
|
Gracie Poulson began Grace Rose Farm in 2016 with her husband out of their first home in California where they planted 500 rose bushes to honor Gracie’s late grandmother and shared content of the process across social media along the way. Shortly after, requests began pouring in from florists and flower lovers across the country, and Grace Rose Farm soon evolved into the leading supplier of cut garden roses in the United States, with over four million shipped annually.
This success led Gracie to make her first foray into the literary world with her book Garden Roses: The Complete Guide to Growing and Arranging Spectacular Blooms, released on March 26, 2024, where she unveiled her most coveted secrets on cultivating, nurturing, and crafting breathtaking blooms.

May 2024: Growing Mini-Roses in Pots with Suzanne Horn
|
It was wonderful to have a large audience who came to learn how to grow mini-roses in pots from Rosarian, Suzanne Horn. Suzanne shared her valuable secrets for growing award-winning roses. She shared specifics on how to pot them to create the ideal growing environment, and how to care for them to maximum growth. What a great opportunity to learn from an expert!

It is with great sadness that we report the passing of one of our longtime members, Barbara Schneider. Barbara was born in Iowa on July 9, 1932, and died February 18, 2024. She moved with her husband, Jack Schneider, about 60 years ago to California. She loved to grow plants and flowers, so her perfect job was floriculture superintendent for the Ventura County Fair. She was the only superintendent to work full time at the fair grounds until her retirement about 3 years ago.
She had a fuchsia nursery in Oxnard. She was a fuchsia hybridizer and later became a rose and arrangement judge for the American Rose Society. With her partner, Sue, she traveled to Northern California, Arizona, Las Vegas, and New Mexico. For about 33 years, Barbara and Sue judged rose shows and spoke at the club meetings - especially in Southern California. It was a wonderful life.
Barbara and her partner Sue Diller supervised the rose shows at Fair Friends of Roses Society as well as the Ventura County Fair Rose Show for many years. They grew about 350 roses of all kinds. hey needed to see how they grow here in Ventura. They were also great supporters of the Ventura County Rose Soceity. Their loss is incalculable.

Barbara's husband, Jack, died about 30 years ago. She is survived by her family; Sue Diller, Dog Mindy, and Cat Boo. Memorial contributions, instead of flowers, may be made in her name to a garden or to the Humane Society. As per her request wishes, she had a private memorial service with her family. She will be greatly missed by all of us who knew her.

CONSULTING ROSARIAN CORNER

Rose Horticultural Tips for May and June
|
by Tom Cooney, Master Rosarian
|
|
|
It may not seem like it with the late spring bloom cycle we’ve had, and some of us still waiting for that cycle to finish, but it is the end of May. Where did this year go? And RAIN, RAIN, RAIN! Wasn’t it delightful! NO MORE DROUGHT! ! I’m sure we’ll be looking for cooler days soon enough as the “May Gray”, June Gloom” days transition into the “lazy days of summer”. As I usually do in June, here are some things to keep in mind to keep your roses looking great.
Fertilizing and Pest Control
June Tasks:
You should stay on your normal fertilizer schedule as we head into summer. I don't really count June as part of the summer for the coastal communities since our coastal weather USUALLY is cool and gloomy and doesn't really start to act like summer until sometime around July 4th. Inland rosarians will start to heat up in June and should start to reduce the amount of nitrogen. They should cut back on synthetic fertilizers over 10% nitrogen unless you are using a time-released product that will slowly give the bushes all the nitrogen they need in small doses.
I’ve found it best to stay with a good organic fertilizer with NPK of around 5-7-5. The organics will break down slowly as do the time-release products and are usually less expensive. You can also stay on your monthly schedule using organics, making it easier to remember. Remember, Hot Weather Means Chilli Thrips, and Chilli Thrips like new growth so it’s best not to force heavy new growth as we heat up.
Prevention is the key to keeping fungal out- breaks under control. Botrytis, black spot, anthracnose, downy mildew, powdery mildew, and rust all flourish at temperatures of 59 to 75 degrees. All these diseases will subside as temperatures reach 80 degrees and above. Luckily, there is an organic product that handles most of these problems; Potassium Bicarbonate in the form of Green Cure or Milstop has been a proven source of control for all but the most severe cases of fungal diseases; so, a regular spray program is the best bet for avoiding heavy infesta-
tions. As always, follow label directions and use proper protection. For severe infestations, you may have to go to a chemical alternative. But remember, prevention is the key.
July & August:
As we get into the "real" summer in July you can start thinking about reducing your feeding program as the heat arrives. Think about a one-time application of Osmocote 14-14-14 or Nitroform 38-0-0 which release slowly over the summer to keep a steady supply of nutrients. Also, an application of magnesium sulfate (Epsom salts) and chelated iron at June month end will carry through to the fall. July or August would be an excellent time to apply a cup of good organic fertilizer to each bush, Organics makes a great summer feed because they release slowly, not pushing growth while the bushes may be under heat stress.

Any of the excellent organic products from Gro-Power, Gardener & Bloom or Dr. Earth will work. Insects love the heat, especially thrips and spider mites. Spider mites can be blasted off the plants with jets of water. If an infestation becomes intolerable, insecticidal soap or neem oil (not with temps in the mid 80’s for neem oil though) will take care of mites; Spinosad is economically best for thrips and rose slugs. A locally available product that contains Spinosad is Monterey Garden Insect Spray or for a more potent formula use Conserve SC. Always use these products when it's cool in the early morning or late evening when bees are inactive. One insecticide/miticide that I have used with good results and with the best safety rating is Azadirachtin. It is an extract from the Neem tree seed and can be applied during 80-degree weather since there is no oil. Several good products with this active ingredient can be ordered online.
Chilli Thrips
For many rosarians over the last few years, hot weather has meant the arrival of chilli
thrips. The approach to controlling them has been spraying with spinosad (Conserve) and imidacloprid (Merit) and as I stated azadirachtin has proven to be effective in my
Garden. Since chilli thrips attack new growth, it is only necessary to mist the new top growth to keep them under control but spray if you want to avoid these pests, at least until someday a natural predator arrives and takes control.
Watering
Of all the advice on growing roses during the summer, the most important ingredient is WATER. Simply water! The rate of transpiration of moisture through the foliage can be tremendous. Water taken up by the root system must be in balance with the loss of water through transpiration, otherwise, the foliage will wilt. In general, it is recommended that during hot days of 90F and higher, watering on alternate days is best. Potted bushes may need daily watering. The best time for watering is early morning. But on extremely hot days, a fine misting of the plants will help keep the foliage hydrated. You also might want to give some thought to using a moisture-retaining spray. Some good ones are Moisture In, Jaz and Cloud Cover. These products put a coating on the leaves to slow down the transpiration process, avoiding heat stress. If you’re growing roses in pots, you may have to water them daily when temps are in the 90’s or higher.
Mulching
The second most important piece of advice may be maintaining a 3–4-inch layer of mulch; this is highly beneficial for several reasons. One, it improves water conservation, minimizing moisture loss from the rose beds after watering. Two, organic materials decompose over time, providing a natural source of humic acid - humus being the end-product of decomposition. The humus then works its way to the lower soil levels improving soil fertility. Finally, most mulch is a natural barrier to the growth of weeds, reducing the need to use herbicides and reducing the loss of water to weed uptake.
Pruning.
Toward the end of August try giving your bushes a “summer prune”. Cutting back your bushes by 1/3 encourages good fall bloom and gets them ready for the rose shows in late October and early November. Give these ideas some thought and enjoy your garden this summer.
