Hello, Last year I sheet-composted an area with intent to plant kalmia and rhododendrons in a "cascade" effect, kind of sprawling their way down the small hill. Of course I failed to research the plants first! This year, the sheet-composted area is nicely broken down and incorporated a bit into the ground below. pH is 5.5 to 6.5-it varies from one section of the bed to another. I plan to top dress with more tasty compost before adding plants. I need help finding places to read about the rhododendrons! I've searched online a great deal and scanned a few library books for specific answers to my queries. Haven't found the answers yet. Rhodos generally indicate particular hardiness zone(s) or temperature ranges for cold tolerance, but not heat tolerance. I live where winters are cold and long, but summers can be devilish hot and humid. Low temps can go to -15 on bitter days, and highs can go to nearly 38 on the hottest days. Those are the extreme ends of my range. What effect does wind chill have on hardiness? It's windy here but I've planned this particular garden in a well protected spot-nary a breeze to ruffle their leaves. They have the morning sunshine then high dappled shade from around noon on. All the rhodos I've seen around here seem robustly healthy, but not one is planted on a slope. They're all in level ground. I wonder if levelling their spot by use of a wall would be better for them, and forget the cascade effect. Well. Sorry to unload all the questions here. Figured if you knew the sorts of questions I have you could direct me to certain publications. Thanks for any ideas!
