New roses dilemma

Hi all,

I bought two fragrant climbing roses, Guinee, from my local garden centre which i planted about a month ago. I dug some composted horse manure in the soil when i planted them, hoping to give them a good start, but they seem to be really struggling.

Both plants have developed purple and black spotting, some leaves have fallen off, others have curled. the new growth and the one bud they had have become very brittle. Shortly after i got them i found they had green fly so i have been using soapy water. One is planted in my south easterly back garden in full sun, theother is against the front of my house in a protected north westerly position.

What i need to know is should i take these plants back, they came with a guarantee, or is it normal for newly planted roses to take a while to settle in?

I'm new to roses so any advice would be much aprreciated

Cheers sunny X

 

You shouldn't be having this problem, it isn't normal.


You should spray with soapy water out of the sun, and then after about 20mins rinse off again. It kills the aphids by suffocating them and will have done its job by then. You could crush them between your thumb and forefinger-it takes a bit to get used to doing it but it is the best organic way to deal with aphid.
There is a chance that if you have sprayed and then they were in the sun then that will scorch the leaves.


Another likely cause is blackspot-a common enough fungal disease, that can be treated.


Was the manure well rotted? And have you been watering the rose?


A pic would be helpful.

 

Hi sunny. It might be of some benefit to you to take a look here http://www.gardenerscorner.co.uk/forum/showthread.php/pests-diseases-rose-20297.html
It describes several problems associated with roses. Blackspot seems like the favourite in this case, as Claire says. It's a very common disease, but several remedies are available :thumb:

Thanks for your replies. :gnthb:

Wiseoldowl, they are both the same rose and both in the same condition, so it could well be my planting technique that is to blame.

I did wonder if it may have been the horse manure, it was a bag i got from haskins, a large garden centre near us, it is well rotted, but i'm not sure how well i dug it in and i didn't spread the roots very well when i planted, is that a big problem? Would it be better to replant, spreading the roots better or leave them as they are now.

I think i may have shocked it and in it's weakened state with a bit of green fly it's picked up black spot, i'm going to buy something for that tomorow.

Lollipop, i know what you mean about squishing the green fly, it is the best way, i had nightmares a few years when i had been squashing cabbage white catapillars on my brocolli plants, euwgh the smell :euw:

I did do some research on the net but as is often the case, answers usually lead to more questions!

Cheers
