Double Knock Out Roses As Cut Flowers?
Comments (1)Not very well. If you cut it just as it is opening and don't expect it too last long, you might get a couple of days out of it....See MoreCan I prune my double knock out roses now?
Comments (16)I haven't had roses long either, but I think it is fairly easy to see where to prune in the spring. Wait to do it after your last frost which should be around March or April. It is a signal for your rose to start growing again so wait until you are sure it is safe. Now, when you look at your rose this spring you will see brown ends on the canes. That is dead wood, and you will cut all of that out. Make your first cut just below the brown wood into the green part of the cane. If you don't see any green cane then prune down to the soil. If the green cane is all white inside like an apple, it is good wood. If the inside is brown then you need to prune further down. Watch for dark areas on the green canes. That is canker and you need to prune below any canker you see. Once you have finished pruning seal all the cuts with something. I use regular white glue, but you can use carpenter's glue or nail polish. That will keep out borers which would otherwise lay their eggs inside the cut end of the cane. Feel free to stop by the rose forum for more advice. I post there quite often and everyone is very helpful....See MoreAnyone planted Knock out or Double Knock out ?
Comments (8)The original Knock Out, along with Blushing and Pink, do very well here. There are several public plantings of the original Knock Out in Eatontown, they get minimal care. If they get any blackspot at all, it is minimal, and there is no leaf loss. Double is brand new this year (I saw 5 at Middletown Garden Center today, pounce if you're into it), but it is expected to have the same characteristics as it's "sister" Knock Out....See MoreDouble-knock out rose bushes too late to prune?
Comments (5)Denise, Landscape roses like Knockout Roses are very vigorous growers, so you prune them to give yourself some control over them. Otherwise they can get amazingly big and start looking kind of wild. The "rules" for pruning them are not necessarily the same as they are for some other roses like hybrid teas because they are landscape shrub roses. Some people don't prune them their first year because they want to get a good idea of how the natural shape of the Knockout rose is going to progress. Some folks prune them back only every other year because they want them to be huge monsters but know they have to maintain some sort of order and control. You just have to figure out what works for you and the space you have as well as the vigor of the particular Knockout you have. Some Knockout types get larger than others and some grow more vigrously. When you prune in late winter to early spring, you are doing so in order to control the shape and size of the bush, and to keep new growth coming out near the bottom of the plant. Remember that I mentioned my mom quit pruning her roses and the base of the plants became very ugly. Well, that "ugly" is what you want to avoid. If you don't prune, then the new growth comes out higher and higher every year and the bottom of the plant looks awful. I haven't grown Knockouts, but they probably should be pruned back to the 5, 6 or 7 largest canes each spring--removing what you need to in order to maintain the shape you like and that fits in with your landscape. You always remove the oldest and woodiest canes, because as they get older they just get woodier and woodier and don't look that great. Because Knockout Roses can be very vigorous growers if planted in ideal conditions, they sometimes need "corrective" pruning in the middle of the growing season when they send out an occasional limb that just shoots out from nothing to 2 or 3 feet almost overnight and is growing in the "wrong" direction, like directly into the wall of the house or a pathway or whatever. I don't think you have to deadhead Knockout blooms though, as they are self-cleaning. A friend of mine describes the more vigorous Knockouts as taking on the appearance of a drunken spider if left too long without corrective pruning, with long legs sticking out this way and that way, and she's not the only person I've heard describe them that way. I have a couple of David Austin English Roses that get that same "drunken spider" look in the middle of the summer, especially after a big rainy spell. They just send out canes out of nowhere that go this way and that way. I prune them out as needed and don't seal the cuts. They heal over just fine on their own. I googled and found you info on "Pruning Knockout Roses" and linked it below. Dawn Here is a link that might be useful: Pruning Knockout Roses...See Morejoannemb
