Winter Kill Results.
I think its time to tabulate my
winter Kill experience for the benefit of the cold garden grower. As a primer, this winter it got down to -13F and stayed there several times. I recorded a -18F in my back yard which has a cooler micro climate. I do not protect my roses in any way except for the mulch that is always present on the soil. Most are own root if grafted I will note that. Most exposed. Prairie Princess - No kill. Jacques Cartier(M Bochella) - No kill. Clair Rose - No kill. Salet - No kill. Heritage - No kill AbrahamDarby (3' high) - No kill. Felicia - No kill. Garten Direktor Otto Linne - No kill (6" planted in October now 12") Aloha (4' plant) - No kill New Dawn(13') - No kill Alba Meidiland - No kill Bubble bath (6") - 3" of kill recovering nicely pom pom de paris - Dead Pom Pom Blanch Parfait - No Kill Gloire Lyonnaise - 6" of kill recovering nicely. Winchester Cathedral - No kill Excellence Von Schubert - No Kill Fairy - No kill of course. Kaiserin Auguste Viktoria - No kill Really surprised me. America (grafted)(Back yard) - No Kill again surprise surprise Veterans honor(grafted backyard) - Minimal recovering nicely. Eden rose - No kill John Clair - No kill (tough tough rose) forgot to water for 3 weeks in summer still survived. Rosemary rose - Minimal kill More protected still -13F Candelabra(grafted) - No kill. Pilgrim - No kill St Patrick (1 grafted 1 own root) - Substantial kill but already back to 3'. Guinevere(Grafted) - No kill Lavender Lassie - No kill (first to bloom) Ambridge rose - No kill Compassion - 6" of kill slow to recover Stunning. This seemed such a hardy rose. Show Biz(grafted) - Dead. Shed no tears. Iceberg(5' plant) - Minimal kill growing nicely. Darlows Enigma - No kill finally shed some leaves. Graham Thomas - No kill but slow to restart. Pink Gruss An Aaachen(Mosaic) - No kill slow growth. Louis Odier(8' plant from 6") - No kill racing with LL to bloom. Alexander Mackenzie 6' - No kill getiing ready to bloom Sunsprite - No kill slow to get going. Lace Cascade (grafted) - No kill but shovel pruned. Everblooming Cecile B.(11') - some kill but recovering nicely All the others were in extremely protected locations so the results are probably tainted. There also several I can't remember right now. My 61 potted roses are still under evaluation. As far as I can see 6 have died and 3 have substantial damage. About par for me. But I will report on that later. -- Theo in Zone 5 Kansas City |
