This is a DA Mary Rose bought about about 3 months ago.
Over the last 2 days and particularly last night in the rain most of the bottom half of the bush has de leafed .The branches seem dark and discoloured.
The top half is green with lots of buds???
Do you think there is dieback here or should I not worry.
Here is a photo of the bud union with all the darkened branches,esp on the left side of the lower part of the bush and lack of leaves.
Help!!
Thanks

| michelle...i can't tell from thr photo...ok.....keep in mind when roses go dormant they go to sleep from the bottom up-....ie:...they will de-foliate below...first...it could be that....or....if it has de-foliated suddenly...the leaves have gone dry and crispy?...maybe some have purply blotches over them?....maybe purply blotches on the stick parts that carry the leaves?....if thats the case it's more likely to be a fungal disease called downy mildew...you see it a lot around now and around october or so.....if any of this rings bell.....keep in mind you'll be prunning soon anyway...so your not really trying to save foliage or flowers....if it was on the leaves only...i'd prob say leave it alone....if it's on the stems....i'd prob advise to give the rose a good hair cut....and if poss cut the "blotchy" areas away and spray with...hmmm.....mancozeb plus 2-3 times at seven day intervals.....hope thats of help |

Thankyou Brenton a very helpful reply.I didnt know that roses go dormant from the bottom up. In that case I wont worry it sounds like a natural process.
I am very relieved!
cheers

| cool....understand though...that when things go wrong with roses it is usually simple things...and these simple probs tend to repeat themselves each and every year.....the main thing that will change is your knowledge in reconizing probs and thus solving them....when you learn to drive a car...the car is what teaches you to drive it........drop the clutch..probs...etc etc.....people can tell you what to do but it can only ever be the car that will teach you....roses are exactly the same...though the process is a lot slower....give it a year or two....listen to the odd so called "expert"(good luck)....and once armed with a bit of info....the rose will ALWAYS teach you and tell you whats up...you just have to learn to read the signs!.....having said all that.....yes...roses go dormant from the bum up...but...i would take a wild stab in the dark and think more along the lines of downy mildew.........i would suggest that most growers when confronted with something theyare not sure off....be it novice or "expert".......the general procedure is to give it a trim...a feed...and keep the water up to it.....this time of year it's usually the water (humidity) thats working against you (fungal disease)...but i hope you get my drift. |
