Fortuniana Rootstock
Comments (23)I'm not TD, but I've grown the rose bush Fortuniana and I've tried to grow roses grafted onto Fortuniana. Fortuniana (the rose) survives here even when the temps get below 0Fahrenheit, albeit with some dieback. The survival of the rootstock (for a decade now) emboldened me to try roses grafted onto that as rootstock. That was the problem. The roots are so strong that they keep pumping through winter, and that means growth of new canes and stems, even though it's freezing and the new canes and stems will die. People I know who are growing roses grafted onto Fortuniana in my zone and colder do serious protection of those roses through winter; this can be as massive as plywood boxes with stuffing (Memphis TN) and other mounding of protections. For Idaho, the question would be, will you have a long enough growing season to make this worthwhile for the rose to grow vigorously to offset the months it spends in serious protected conditions. You could try one rose on Fort and the same rose on other rootstock and see which one works better for you over three or four years....See MoreRose Vendors with R. fortuniana Rootstock?
Comments (25)Petalz, 'Fortuniana' normally does not make seeds, and even if it did, they'd likely not grow true-to-type, since it is not a true species. It also resents being bare-rooted and normally dies afterward. I know that we sent virus-free 'Fortuniana' to members of the Honolulu Rose Society, a decade or more ago. Do you know any of those folks? They may be able to supply cuttings within the state. Back to 'Marechal Niel' -- It has been suggested that much of it has a virus (likely NOT rose mosaic) which makes it difficult to grow. As far as I know, no one has ever proven that. But in any case, it does seem that some selections do better than others. We got ours from the plant Greg Grant and others found in Texas -- a very vigorous and carefree form. We then heat-treated it just in case. On 'Fortuniana', it is the most vigorous rose I've ever grown. We've distributed many of those plants, mainly at HRF meetings (Lakeland in 1991, Lakeland 2001, and El Cerrito 2002). ARE also has this form of the plant. So they're out there. Vintage also seems to have quite a good form of MN, but from a different (California) source....See Morefortuniana rootstock planted deep
Comments (19)Karima, I forgot to add that fortuniana can take up to 3 years to get fully established. However, in the meantime you should still see some progressive growth and blooming. After about a year it can be pretty impressive. I think your idea of clearing some of the mulch away from the base of the plant is a good idea. If you have piled any extra soil on top of the roots, I would gently skim some of that off with your hands. Don't poke around though, or you'll disturb the roots. I've had some of my bushes sink down into the ground in the past, and they did fine as long as I kept all the excess mulch and soil that wanted to keep caving in cleared out. Now I plant them a little high, as they always seem to settle some. One of the biggest advantages to fortuniana is that it is able to extract nutrients more efficiently from sandy soils. That's why it is the best rootstock for sandy areas. The fact that it is nematode resistant is a plus. (It is not nematode-proof though. If you have a huge nematode problem, it can get the fortuniana also). Nematodes are able to move through sandy soils easily, by using a swimming type of movement. There are many types of nematodes, including lots of beneficial ones. "Bad" nematodes do not like organic matter, probably because it results in lots of beneficial organisms that kill the bad guys, and maybe makes it difficult for them to travel. It's always a good idea to add some organic material when planting, top-dressing with some periodically, as well as adding a good layer of mulch. It seems to inhibit the destructive nematodes. Keep the mulch (pine bark, or whatever) a good 6 to 12 inches away from the base of the rose. Hope all this helps! Sandy...See MoreWhere to buy Fortuniana Rootstock
Comments (2)Monahmed, Cool Roses in Florida sells potted Fortuniana for budding and grafting. I have not purchased from them. I just remember seeing that they sell the Fortuniana I tried rooting Fortuniana with no luck. I think it wants to have a humid environment, with barely damp rooting medium... at least that's what I'm going to try next. Good Luck to You! Gracin...See MoreBenT (NorCal 9B Sunset 14)
