How to have healthy soil & roses, organically?
Comments (21)Hi Jasmine: That fertilizer recipe of 4 gallons water & 1 cup alfalfa meal & 1 T. molasses sound great !! Thank you. Few mistakes that I did which I hope others won't repeat: 1) Last year: The deer ate Sweet Promise and Firefighter hybrid. They were so bare without leaves, so I gave them high nitrogen fertilizer NPK 10-5-4. That burnt both in high heat, plus drove down potassium & calcium. Both had lousy blooms, plus cane-borers invaded Firefigher's weak stems. 2) Chicken manure is best only twice a year due to its salt. GERDA in HMF, zone 6b, has the best garden, and she uses chicken manure twice a year, after 1/2 bucket of cow manure in spring . Jeanie in PNW informed that the rose park fertilized with animal dung in the spring, and nothing afterwards. Cantigny Rose park here did that a decade ago, and it was their most healthy year. 3) My most healthy rose, and best blooms to leaves ratio is Arthur Bell. I did nothing, except chicken manure before the ground freezes, and the second time early spring. 100 % healthy with glossy foliage. 4) My worst rose, full of black spots, is Yves Seedling #2. It went from 100% healthy early spring (winterized with manure & cracked corn), to disease-fest. That rose has the most salt-damage: 2 applications of chicken-manure, plus sulfate of potash to produce more blooms, then ground limestone & red lava rock, then 2 soluble MiracleGro. I tested to see if chemical fertilizer induce black spots, and it sure did. 5) The stingy roses like Frederic Mistral, Jude the Obscure and Eglantyne BENEFITED from once a month of sulfate of potash & gypsum .. more blooms. Frederic is still clean with ground-limestone & red lava topping. Jude and Eglantyne broke out in B.S. with MiracleGro soluble. Salt in chemical fertilizer drives down potassium, necessary for disease-prevention. 6) Comte de Chambord in the ground is still clean with one application of sulfate of potash & ground limestone & red lava rock. Old Port next to it gets 2 applications of MiracleGro, and broke out in black spots. For pots: Duchess de Rohan and Rose du Roi gets sulfate of potash & gypsum ... both are still clean. Wimpy Duchess de Rohan also gets blood meal and some chicken-manure, still 100% healthy. Chicken manure is high in boron, zinc, and copper. Both zinc and copper are anti-fungal agents. La Reine and 2nd Comte de Chambord in pots: Both broke out in horrible black spots after 2 MiracleGro applications this month. I use less than half the amount recommended. 7) Same report with roses in front: none of these had brewer's yeast nor rice bran. The ones that got chicken manure only are 100%, the ones that got MiracleGro broke out in black spots immediately. I can't wait until more rain to de-salt the damage of chemical fertilizers. Less is best, and slow-released like manure is best. 8) Few years ago I used Lilly Miller acid fertilizer NPK 10-5-4 with chicken manure, plus chemicals. Great spring flush, I get impatient, and give it the SECOND time early June. It got hot & dry, and Mary Magdalene broke out in mildew, DID NOT improve no matter how much tap-water I gave. So this year I learn my lesson: nothing on Mary, except spring application of chicken manure. She's 100% clean, tons of buds. Below is Mary Magdalene's 2nd flush, taken today July 5....See MoreHealthy No-Spray roses: what are yours?
Comments (43)Vaporvac, I would recommend every one I've had experience with for being disease free and withstanding neglect. Some of them are outside the garden area, and I just don't get to them very often. I've never seen black spot or powdery mildew on any of them. Wm. Baffin - big guy - never gets any care except to be whacked on unmercifully by my husband when canes get in the way of the mower. They're in almost total shade and have a great early flush, then intermittent blooms throughout the season. In my opinion, best for great color at a distance because the individual blooms are sweet and pretty, but not extraordinary or breathtaking. John Davis and John Cabot are reliable for color all season. They're both giants. The Mordens - Blush, Centennial and Sunrise are excellent bloomers and fit into a garden of shrub roses of normal size, Centennial being the tallest. Bill Reid, a bright yellow that blooms constantly. Also, a good rose bed size. Martin Frobisher, rugosa, has the most delicate looking blooms, but is a strong, healthy bush. So far, it's not a giant. They never need winter protection and seem to do fine whether pruned or not. Winnipeg Parks and Campfire are two I would like to add. Mine are all own root from Northland, and have never been sprayed....See MoreHealthy DA climber rose similar to Lady of Shallot?
Comments (21)@Adelaide (Z8b Canada) ..Adelaide... DA shrub roses of 4.5 feet or above, generally have a dual personality... some might use more colourful terms to describe it... in that they can be grown as a shrub, or as a climber.. that choice is with the gardener.. although the rose will often tell you in no uncertain terms, which way they intend to go, like it or lump it... I've grown a number of them as short climbers very easily indeed.. DA's heights are just a guide, transcribed direct from the UK inventory and can often seem ridiculous when you've had the rose a few years.... the only ones I know that perform true for us, are those marked 3.5 feet or lower.. and there aren't many of those.. Unlike the ever popular Gertrude Jekyll... Royal Jubilee has fewer thorns, better foliage and repeats much better.. I am in the driest [if that's the right term] part of England but we get rain, and humidity is nearly always high.. I get my share of black spot such as it is here.. you may have more strains to deal with where you are though... so it's perhaps not wise to take my experience and relate it to yours but it's all trial and error isn't it?... I really want that rose again, I had to remove it due to building work on my property.. I want to grow it again one day, as big as it could get... let the thing rip, you know?... best of luck......See MoreRandom Qs & Observations about growing Healthy Roses
Comments (138)Here's a random observation for the morning...I only took 2 cuttings this fall to try and root over the winter and both appear to have taken. After reading one of the other threads about biochar I took a handful of small chunks of burnt pine from the fireplace and mixed that into the soil when I planted them. That is the only new difference from all my other failed cuttings (I do not have a good success rate! These are #4 and #5 out of hundreds of attempts). It may or may not be what made them both work, but I thought it was interesting to note....See MoreRelated Professionals
