The rose database would be improved immeasurably by the addition of more comments. Please try to add a comment for every rose growing in your garden, addressing issues such as heat, rain, humidity, pest, and disease resistance. That's my project for this winter.
The roses in my garden that grow well for a couple of years and then decline are mostly hybrid teas and floribundas that were never meant to grow on their own roots and never will reach their full potential unless they're grafted. The shortage of sources for grafted roses is a much bigger problem for me than heat. That's why I've stopped buying roses from Vintage Gardens, Northland Rosarium, and Rogue Valley, which once were major suppliers for me.
