Roses will uptake maximum nutrients when the soil pH is between 6.0 and 6.5. This reading changes in different locations of the garden. Other factors that change pH include use of chemical fertilizer and when the pH is tested, before, during or after the rainy season. West of the Cascades, the native soil tends to be acidic. (East of the Cascades the soil is alkaline) My Kitsap garden beds have had readings on October 2, 2016 between ph 4.5, pH 5.0 and pH 6.2. I applied granulated lime according to directions on the bag after these readings. You may have heard that lime is a slow acting soil amendment. I waited three months, until late December, to find pH in all rose beds to be pH 6.3 and pH 6.6.
I did not think this chart would project very well in the Rainier Room and even if it were projected, it seems to me to be something to study to fully understand.
The excitement is building now that the holidays are behind us. The 2017 Northwest Flower and Garden Show will be here before we realize it. This is the traditional kick off to spring in Seattle. Speakers and vendors crowd the convention center for a jam packed five days of garden glory. I love the display gardens to get inspired for the growing season. This year I will be speaking about roses on Saturday to kick off the the bare root rose growing season. I am so excited I can hardly wait. My program is finished and gets tweeked every week.
Let me start this discussion by pointing out that some roses are protected by plant patents. David Austin roses and many Weeks modern varieties fall in this category. It is illegal to propagate roses with plant patents. The large rose producers need to protect their investments in roses with plant patents. That said, many old garden roses, polyanthas and miniature roses do not have plant patents. Do your research before propagating roses.
I am not into budding onto rootstock, but I have had modest success with starting hardwood cuttings in fall. I credit my success to the continual rain in the Pacific Northwest providing the outdoor moisture. My method is simple: hardwood cuttings, rooting hormone powder and small potting mix filled containers. Roots form within two months but the starts will not be potted up until next summer or fall.

Saturday I was with a group of 18 very good rosarians from the Tacoma Rose Society. A long time member, George Hedger, passed away and formally left his 450 roses to TRS. Decisions were made to have a rose rescue and dig out, wash and pot the best roses for a sale next spring to benefit our beloved Point Defiance Rose Garden, that George so loved. My guess is the crew processed 170 roses.
With the dog days of summer upon us, the majority of my gardening chores are done in the early morning or in the late evening. More and more, I am finding myself sitting on the porch under a box fan with a cool beverage and reading a good book.
An early adopter in many respects, I must confess that I have never been able to convert my reading habits from a book to a nook or other electronic reading device. There is just something about the feel of a book, the smell of a book, the satisfaction you get when you complete a book and can snap it shut, after being filled with its knowledge.
I am a firm believer that everyone should have a personal library of the books that they love. Electronics often fail, things get lost in the “cloud”, but I can always go to the shelf and…
On the whole, I average 25-75 emails per week from folks asking rose related questions. About 25% of those are questions related to how to grow roses from seed. Growing roses from seeds can be done. It takes patience. In order to produce a mature rose shrub from a seed is a multi year process and is not for the faint of heart.
the ‘Osiria Rose’ – is actually a rose but is not sold in the U.S.
Many times people who write to me have already purchased seeds. Sometimes, they send along an exotic photo of an unusually colored rose supposedly grown in some far off land. They always tell me that they spent $$$ (+ Shipping & Handling) and are very disappointed with the results. Either the seeds failed to germinate or they produced a totally different bloom than what was advertised. Or, the shrub is spindly, sickly and rarely produces any blooms at…
This gardening season I have been thinking about my rose growing hobby a lot. I like rose horticulture exhibiting, making arrangements and growing the miniature and miniflora roses and I am moderately successful, especially since the move from the short growing season in Minnesota to western Washington. To do really well, a person needs some type of florist frig or other not frost-free frig that will stay at 36* F to hold roses for a week or so before a show. It will keep a perfect bloom in that state for days until needed. All the really good rose exhibitors have a special frig. I do not have such a frig. The frig really only needs to be using electricity for a month or so in June then a month in Sept. to cover all the rose shows in the Pacific Northwest. So I have been wondering, do I want to get such a frig? Do I want to continue showing roses at this level? How many more years would I really want to be showing roses? Would it be worth the effort? What do I really get out of all this? Heaven knows I don’t need more trophies and stuff. I like the recognition and thrill of getting on the head table. I only need one up there for it to be a success. I like being with rose people and judging. Judging is where the real action is, IMHO. So I am conflicted. I like my humble shrub roses with their full fluffy variety of colors. They are not show roses for the most part. Dr. Buck and David Austin are well represented in my rose collection. I am also trying a few of the Kordes varieties this year because of their reputation for disease resistance. So where does this bring me? I will probably continue life without a frig, but I would take one if it magically appeared.

Competition roses in the Pacific Northwest are amazing! I recently returned from Vancouver, WA where I participated in the American Rose Society, Pacific Northwest District rose show. There were two main categories of competition: Horticulture and Arrangements. In horticulture, the hybrid tea rose is always the top winner and is awarded Queen, King, Princess. (I like that Queen is the best 😀) My favorite competition has always been making arrangements according to the guidelines of the American Rose Society. I still get a kick out of growing the roses and doing something pretty with them. Being recognized by my peers for good work is great too. It was a satisfying rose show for me.
I won the PNW trophy for my Oriental free style, naturalistic design using two containers. The roses are the David Austin variety ‘Graham Thomas’.

I was awarded a blue ribbon for a miniature mass design (10 inches). The roses are ‘Jeanne Lajoie’. I made several other designs winning blue and red ribbons.
Six years ago, Orion Roses in Minnesota had a going out business sale and I purchased several roses thinking this one was ‘Celestial’. It is not pink or ‘Celestial’ but since they business is gone, I have no idea what the identity of the rose is. It is quite large, drops it’s petals cleanly and forms oval hips and fills a space but I wanted a re-blooming rose in this location. Do you recognize this rose?
