I sent a very polite email to Parkers to let them know that out of the 6 climbers I purchased last year 2 were stone dead and had never shown any sign of life and 1 other was sickly and hadn't flowered. Here is their response
Thank you for your recent enquiry, we are sorry to hear of your disappointment with the roses supplied. Unfortunately you are now out of guarantee to claim against the failures as we had to be notified before 1 August 2014 on any failures.
Apologies for any inconvenience caused
Bloody cheek! They won't get any more of my money
