Own root questions

19 years ago

How do own root roses do in hot climates (Florida)? I know they aren't as good as fortuniana, but are they better than other rootstock? Also, a really dumb question. If a rose is from a cutting is it considered own root or just the ones from seed?

Thanks,

Nancy

    A rose from a cutting is own root. That's how own root roses are grown. Roses from seed are own root also but each one will be unique and may be nothing like either parent. Because cuttings can require so much of a cane, where you might get two cuttings from a cane you could get up to eight or more bud eyes which can be budded to root stocks to make a similar number of bare root grafted roses.
    This is another reason bare roots are sold by the major growers. With a limited number of original mother plants, more plants can be propagated from one plant with bud eyes than with cuttings.

    Thanks Karl, I appreciate that. One more thing learned.

    Own-root Chinas are said to be nematode resistant. Beyond that, it would be a crapshoot. Multiflora rootstock is terrible, Dr. Huey is said to be good for a few years only. Most polyanthas, hybrid musks, and many ramblers have multiflora ancestors, so perhaps would not be leading candidates. Malcolm Manners at Florida Southern probably knows more about this than anyone.

    When it comes to Florida and rootstock you need to check your own area.We have had many discussions and the bottom line is there isn't hard and fast rule on the subject.Around here Dr.Huey and ownroots do fine.25 yrs. or more which is fine for something that never goes dormant.Other places of course Fortuniana is the way to go.I can't get anybody to respond but I suspect that this is alkaline country and fortuniana is promoted for acidic soil so nematodes may be more of a problem in acidic areas.Those of us in coastal area have soil built up from the ocean.Note the millions of seashells.Inland from the Mountains of Georgia washing out to sea for a million years or so.

    Pete is right. Not all areas of Florida have issues with nematodes. The soil and climate are extremely varied. It's a big state, so I'm not surprised. In fact, just outside the gate from where I live, some of the people are battling hard clay.

    Most of the chinas should do well, and there are many teas (not hybrid teas) that will do well own root also. Some of the older hybrid teas may do O.K., but I haven't tried many of them. Dame de Couer is the only one I tried. It seemed to do well, but I had to move it (which I usually have bad luck with), so I took cuttings and had it grafted. My modern hybrid teas are on fortuniana. Most of the newer modern hybrid teas do not have a vigorous root system on their own.

    I have found that any of the older roses that have a vigorous root system seem to do well. For example, Mrs. BR Cant, Bon Silene, and Madame Lombard can barely be dug out once established. In fact, Mrs. BR Cant will eat your house if you dare go on vacation for a couple of weeks. I cannot imagine her grafted on fortuniana. She'd probably take out the whole neighborhood. The china Louis Philppe can get quite large down here, while it stays smaller in other states.

    You can always obtain what you like and try it out. If it declines you can try to get someone to graft it for you (or learn to graft) if it is one you really like. Grafting may or may not help, as sometimes a rose is just plain unsuited to the climate and growing conditions. It is not necessarily a nematode issue.

    Some people have luck with hybrid musks on their own roots, and some don't. The ones that have had some sucess with them live in the panhandle, so they are further north than I am. I'm thinking of trying a couple, which may be an absolute waste of time and money, but I'm curious so I'm experimenting.

    I have 3 Double Knockout bushes near the foundation of my house that are absolutely gorgeous. They are on their own roots, and getting blasted with the afternoon sun on the west side of my house. Beware of the original Knockouts if they are grafted on fortuniana. They are monsters that get 8x8 and are VERY thorny. They will shred heavy leather gloves, and then proceed to shred you. Grafted ones need a chainsaw. I had them all removed.

    I have decided to grow the tough roses on the front of my house that will be most likely to put up with a huge storm, and still survive. Roses like Louis Philippe and Madame Lombard, Archduke Charles, etc. as well as the Double Knockouts.

    For the most part the chinas, the Bermuda Mystery roses, some teas, and some noisettes (such as Crepuscule) are your best bet, if you want roses that are totally suited to our climate. A good number of them do not ever need to be sprayed.

    Malcolm Manners has done much research regarding nematodes and other issues and has been a great help to me.

    Thanks Sandy. I know from trial and error that I have to have fortuniana in this part of Florida. I just didn't know if own root would be better than Dr. Huey which I know doesn't do well here. Is it somewhere between how Dr. Huey performs and how fortuniana performs? There are so few roses on fortuniana. I'm not crazy about the blooms on the old roses. I have a few but I have such limited space I really want beautiful high centered blooms which you don't find in old roses.

    Malcolm Manners has told me that roses on Dr. Huey will typically fizzle out within 5 years. However, there is a lady in Sarasota that grows many, many David Austins on Dr. Huey, because that is the only way to get most of them, and she says hers are still going strong after 10 years.

    I would say if own root does not work for you and you really want a certain rose, I would buy one on Dr. Huey, and then graft some cuttings (or have someone custom graft for you) onto fortuniana after a couple of years. That way you'll have another of the rose when the Dr. Huey fizzles.

    It sounds like you favor the hybrid teas, so in Florida they really need to be on fortuniana. I have actually thought of growing a few that I like, such as Heirloom (a purple hybrid tea), in a pot until large enough to get cuttings for grafting. Vintage Roses and Heirloom Roses have a large number of own root hybrid teas in bands.

    I have also purchased several hybrid teas from Johnny Becnel Show Roses. There is a phone number for Calvin who handles all the ordering. He buds on virus free fortuniana. If you can't find the number, e-mail me and I'll dig through my messy desk and find it for you.

    I love all roses, in particular many of the old garden roses. However, I also love having some hybrid teas, as they are so beautiful in a vase.

    The chinas are useful for landscape color, and the old teas make a very pretty landscape statement also. The old roses make an excellent replacement for boring green shrubs, are less care than the boring green shrubs, so you may want to consider a few just for that purpose.

    Actually Sandy I prefer floribundas which are even harder to find on fortuniana. I have a tiny lot, 1/8 of an acre, with house, 15x30 pool, 12x8 deck, large concrete patio around the pool, 2 car garage, well you get the picture. I have a very small space to garden. There are large trees and bushes on two sides in the neighbors yards. Every inch that has sun already has roses. I'd love to grow a variety, old, new, HT's, Floribundas, shrubs, etc. but I have to choose carefully since I can only manage a few. I have several in pots, one of them is Heirloom, don't you love that scent?
    That's good to hear about the Austins, I have several, a couple on fortuniana, but mostly on Dr. Huey and they for some reason seem to do OK, at least better than the floribundas. I appreciate your response. It is very helpful.
