More confused than ever
Comments (19)I think in the PNW multiflora rootstock does very well, so you can buy from Pickering and Palatine. I wanted to recommend you to check out Lynette, The Oldrosarian's website. She has a PNW garden with 6-800 roses to die for, with gorgeous photos and useful comments about every rose she grew. Alas, I cannot locate the website any more. Anyway, she gardens in British Columbia, and as far as I remember, she bought roses only grafted on multiflora and laxa. Dr. Huey is the rootstock for the alkaline soils in southern California and Arizona but you probably do not have alkaline soil in the rainy Seattle. As others already explained it, David Austin sells the right to certain nurseries to grow his roses. Some sell his roses own root, like Chamblee's, Heirloom, Vintage, RU, and some sells them grafted - for you the best choice is Pickering who has most of the Austins and their multiflora rootstock is grown from seeds so it is likely virus free. (So far I never got a virused rose from them - Austin or else). Own root, as others already explained you, does not mean that the rose will be virus free. Roses Unlimited announced a few years ago that they will clean up they virused inventory but that could not be done in such a short period of time considering the large variety they carry. There is a nursery on the west coast that guarantees (?) virus-free roses, Roses of Yesterday and Today if you want grafted plants and don't want to order from Canada, though Pickering is less expensive. And, Roses Y&T has very few plants grafted on multiflora but states that they sell only virus free plants. If you are willing to try bands, you have more choices: Northland Rosarium (WA), Heirloom (OR), Vintage (CA). I tried both Northland and Vintage and I was very happy with both though I was very reluctant to try bands. For bigger own roots you can check out Rouge Valley roses (OR)- they do not state that all their roses are virus free but accept the responsibility that no matter how many years later virus shows up they will reimburse you - so far this is the best guarantee I've read. Their selection is fantastic (unfortunately their shipping cost to the east coast is forbidding but for you it should be pretty good, I assume). Chamblee's (TX) has excellent 1 and 2 gallon own root roses, including some Austins, probably at the best price you can find. Their so-called Earthkind roses are the disease resistant ones. (Strangely enough they don't list Crepuscule among those while Crepuscule is one of my most disease resistant roses.)...See Moreis mosaic virus carried in all fig trees?
Comments (22)Like everybody else, I don't like this fig mosaic virus. It's my wish to have trees that don't have this disease. Once you start collecting, there's a huge risk you'll come across a diseased cutting/fig tree. If you are selling or trading cuttings, don't sell, don't trade 'clones' that would carry this FMV into other people's back yards, so to speak. Not all trees have this FMV. There are some countries where it's very hard to spot a tree with FMV symptoms. It's not because they are asymptomatic. It's because the infection is not there.Or perhaps some of the viruses that belong to this collection of viruses that is known as FMV, are not present. And the 'signs' don't show. The truth is, research on this subject is in its infancy. http://oregonstate.edu/dept/nurspest/fig_masaic_virus.htm This post was edited by jesj1852 on Wed, May 8, 13 at 16:24...See MoreHVX - concerned about other plants near by
Comments (20)Yes, your plant appears to be infected with HVX. To Steve_Mass, I'm afraid that the flowering cycle has nothing to do with spreading HVX by the roots when you are digging plants. You will still get HVX on your tools/shovels and you can still move it to other plants so long as they are actively growing. It is best to wait until the fall when the plants are totally dormant. You will still get HVX on your shovel from any dormant plant that has HVX, but since the sap isn't flowing in the healthy plants they won't catch it as easily. Your confusion is from Dr. Lockhart's research that showed that if a hosta with HVX is done flowering and you are cutting SCAPES you won't move it from one scape to another scape. This has nothing to do with moving a plant or cutting roots, crowns, or leaves. So if you cut the scape of a plant that had HVX you will get HVX on your scissors/pruner but then you won't transfer it to a healthy scape that has already finished flowering as there isn't any sap flowing in a finished scape. I hope that helps to clarify things. Wait until the fall, after the plants have gone dormant, and dig it out then. I agree to use a spading fork as you will do a lot less damage, just in case, since Dr. Lockhart's research used too small of sample sizes to draw absolute conclusions....See MoreQuestion about Rose Mosaic Virus
Comments (51)comtessedelacouche (10b S.Australia: hotdryMedclimate) I started each post to you with the following qualifier: "since you are from Australia, you may find these links of use:" Please notice the use of "you may find". I suggest that if you find something in the links that you are interested in obtaining addition information / viewpoints about, that you start a new thread on that point. If your rose growing skills are anything like what I saw illustrated in the annual, congratulations!...See More- 6 years ago
