frustrated and exhausted

18 years ago

we have had the worst spring here on record in vancouver, and then we get a heat wave over night this weekend. everyone of my well cared for roses has broken out with yellowing of leaves and are falling off. this happens within hours and only seems to affect the older leaves. i do not believe it is a disease because even my neighbors roses have got it. there is vigorous growth on all of them, but i am unfamiliar with what is causing the yellowing. i wonder if itis simply shock to the plants- not seeing the sun and very unseasonably cold, to scorching heat over night. anybody else out there in vancouver experiencing the same thing? sorry i do not have pics but it is simply a fading and yellowing of the older leaves at a very fast rate of advancement ty.

    Are these established roses (have been planted in the same spot for a while) or are they new ones that you just planted this year?

    And how much water?

    It might just have been time for those old leaves to go.

    Sometimes you just go with the flow. Every year will being some new fresh Heck that we have to deal with. Nature of the beast.

    The first set of leaves will usually yellow and fall off once the temperature heats up. Some roses are more susceptible, particularly some climbers. In some years, I have hosed the climbers to knock off the yellowed leaves. The plant is quite healthy, showing new healthy growth, but as I mentioned, the first set of leaves is ready to fall or be taken off. It seems this spring as I look out my window, everything is green. The grass is green, the trees are green all of the shrubs and perennial plants are green and the roses look awful! It really is discouraging, especially when one puts so much time and effort into caring our roses.

    Hi Joebar

    You are not alone. I'm in Kamloops and we had the same thing happen here. I was looking at my roses this morning and noticing exactly the same problem. This is on my established roses which have been in the same spot for quite some time.

    Another thing I'm noticing here is that along with the distorted (frost damage) and yellowing leaves, some of the green leaves are getting tiny light yellow or white spots on them. It might be rust I'm not sure. I have been spraying with fungicide so it shouldn't be rust but, you never know.

    I'm just keeping my fingers crossed that as the weather warms up and STAYS warm things will level out and the problem with fix itself. A VERY weird spring indeed !!!!!!

    I forgot to add:

    I was very surprised that this morning a lot of my new growth on my roses (and clematis and aubretia come to think of it) was very wilty this morning. They weren't in need of water as the sprinklers had come on overnight. But the sun was quite hot even at 10:00 am. They perked up later when the sun went in but for a while there I was quite worried. Anyone else experience this?

    Joe I feel your pain. I am in a new house this year...I have lots of roses I put in pots. Hard to know what to do with this weather

    many are in pots and have recently come out of the greenhouse a month or so ago. they all have been acclimated. ironically though- my roses that are in the ground are doing the best of the bunch.

    I have 50+ roses in pots in Kalama. I hate that you all are having rose troubles but am glad to know that I am not alone. I have been so discouraged. Trying to keep my chin(s) up!
