Hi,
Just got a question about tree rose for planting it in Southeast part of Ontario (Kingston). I am planning to buy it at HomeDepot ... the idea of grafting a rose on a tree is nice.
But will the tree rose survive the winter?
Also, will it actually looks as good as the picture on the tag?
Thx
HD roses are generally crappy quality ones that don't make the grade for a decent grower. Seconds. Most take at least a year to catch up with a good quality rose purchased from a reputable mail order or local nursery.
NO, it will NOT survive a winter outdoors in anything but the mildest zone 9 and up climate. The graft is very vulnerable and even a hardy variety can have the graft burst. YOu need to have it in a LARGE pot and bring it into the garage to overwinter.
Only if you spray it preventively for disease and fertilize it like you should all of the other roses you grow. And, only if you choose a floribunda or shrub type. Hybrid teas make very poor rose standards. Grafting a rose that grows to 6' tall on a 3' trunk is ridiculous.
Interesting. Guess Seattle, the Portland area and Victoria BC have moved up a zone or two - tree roses are quite common and add an appealing formal feature in all three cities public rose gardens. I also have a client that has a number of well established tree roses that have wintered over quite a number of years. Will it overwinter without protection in Ontario? Probably not.
