Homemade Rose Compost and Compost Tea...
Comments (267)totoro, my roses have really responded well to the tea. It's the best they've looked all year, so I'm bummed it's getting cold. I so hope all my buds eventually open. I also "accidentally" made some compost tea so I sprayed that with a little bit of AT directly on the leaves to combat BS. It's hard to know if worked, but even the worst offenders haven't caught BS yet, so who knows. Usually those grow back with BS, though. I'll try it from the first of the season next year now that I see how easy it is with my new Chapin mosquito sprayer. Samuel, you are so far ahead of us. We haven't lost any leaves and everything is still green. That will probably change with the cold this week. I've been putting the remainder of this years compost in bags leaving just enough to help with the microbes. I really need a source of nitrogen. Nobody bags grass around here so maybe it's time to try the coffee grounds. The thought has crossed my mind that applying it directly may help with midge due to the ph, but I haven't read any research on that. I have a separate place for my food waste. I'd still like to try turkey manure, but I lost access to a truck so It's bagged for me, I guess. What other easy sources of N could I find? I brought in all my houseplants and cuttings/rootings. I think I can leave my 5gal. potted roses out a bit longer. I don't think my coal cellar is that cold yet. I wonder what the temp needs to be to induce dormancy?...See MoreCold zone rose gardeners who don't winterize. Are grafted roses best?
Comments (16)I really have mixed feedback on this issue. I totally agree that the robust growers in cold zones do fine on their own roots and you don't have to worry about suckers from the graft. Too robust growers (like gallicas) can be better grafted so that you can plant the graft ABOVE the soil (only) for those super-hardy roses and avoid the gallica taking over the garden bed. I also agree that grafted roses of the wimpier varieties of HTs and floris are more robust in their first year or two and tend to grow bushy faster than own root versions of those plants. However, I've recently started to experience the down side of grafted HTs in a cold climate. First of all, virtually all of the grafted HTs and floris that I've planted with the graft properly buried have gone own root over time if they've survived. For instance, I bought In the Mood grafted from a local nursery and it was fabulous and bushy in its first year. The second year and for every year after that, it was a knee high one-cane wonder until it finally gave up the ghost and died after about 6 years. The same process has been happening more gradually with my grafted Savoy Hotel. It was lush (maybe 4.5' by 4.5') and incredible in its first year or two, ranking in my top 20 of roses. Every year since then it has declined and come back from the winter more slowly. By August this year, my plant in optimum sun and soil conditions has just now reached almost 3 feet with 3 canes on it and a couple of blooms here and there for the first time all season (nothing at all in June). Here's a contrast picture to show that effect - this is 2013 in June for Savoy Hotel at its full 4.5'x4.5' glory. Savoy Hotel is at the bottom right corner keeping up with Madame Isaac Periere in the back of it with no trouble. Granted, this was a particularly good rose year, but you can see the relative sizes. Now just one year later in 2014, here's Savoy Hotel in front of MIP (bottom center) also in June, and this was an average rose year for me. It's too late for MIP on the shepherd's hook to be blooming, but you can see MIP's height by the purple clematis. Notice that she's now in 2014 only 3' high and has about 4 blooms every couple of weeks. She has declined from that since, even though she's still a very nice rose. I don't have any more recent bush pictures for her since I only get the scattered blooms any more, and only late in the season to boot. One other effect I'm seeing in my older grafted roses this spring in particular is graft failure for a lot of my well-established roses with the graft well buried. Even under the soil, it seems like a grafted rose starts running out of places to grow new basal shoots after a while. For instance, this spring I lost an 8 year old Dream Come True (the tall rose at the left of the first picture) for no good reason that I could see, and it was a mild winter. Sure, you see pictures of 50 year old grafted HTs in warm climates, but those are warm climates. I suspect that if we have a 50 year old HT rose in cold climates that started out grafted and is still alive, it has gone own root in that time and is a robust rose on its own roots. My reluctant conclusions are that if a rose is going to be a wimp, it will reach that state on its own whether own root or grafted. If I get an own root HT rose through its first winter it will increase in size to its sustainable height and vigor and more or less stay there for the duration. If I get a grafted HT rose through its first winter, it will decrease in size to its sustainable height and vigor and stay there till the graft fails or it goes completely own root. There are only a few roses where I think the graft did give the rose a little boost in survival over that first winter, Memorial Day and Oklahoma come to mind, but for the most part I don't think it buys me anything in either survivability or vigor after the first year. That's why I tend to grow my HTs and floris on their own roots. I want to know the long-term height it's really going to be in its early years, I get reliable winter survival of the original rose from own roots if they get to a good size in their first year, and I don't have to dig up a massive root system when it dies or deal with suckers. Just my two cents Cynthia...See MoreCanadian Heritage Roses - Cold Hardy Roses
Comments (41)Frances - I doubt not spraying has anything to do with the hardiness of the rose unless you think the rose is less healthy going into winter? My few roses die back almost to a foot high most years. I do understand if you are looking for a climber, it is so much better if they are tip hardy. And I see Captain Sam Holland is a climber. I took a look at that Felix LeClerc and it’s gorgeous. No fragrance I suppose? The photos on HelpMeFind don’t look like the photos the nurseries present. Beautiful coloring if the nursery photo is correct. John Davis is one of my favorites but because there is no fragrance at all, I have not bought one. So pretty though....See MoreCold climate/northern garnders, show me your roses please!
Comments (97)Al: Gorgeous garden, what are the yellow roses in your pics? Also what type of soil do you have: loamy, sandy, or clay? What's the lowest layer of your soil? Thank you. I try to UP my winter-survival, lost many roses in poor-drainage clay. At first I felt bad, but many street trees here (N. Aurora) also died through freezing rain & poor drainage clay in my area. Now I spend at least 1 hour digging a hole, after testing for drainage by dumping a 5-gallon bucket of water. I have rock-hard clay above, with yellowish rocks & sticky & hard clay below that water can't drain fast enough for our heavy rain. Small comfort: Here in alkaline clay I have very little blackspots & no spray compared to my last garden of acidic clay in Glen Ellyn....See Morestrawchicago z5
