I'm delighted to hear that your roses are now surviving the tough conditions you face. It's good to know that soil amendment can make a difference. And I'm happy that the growing season is coming around in a timely manner.
If it's not one thing, it's another. Once I get the soil right, I may need to worry about water.
Two days ago DW and I took a bike ride around a local lake, Willow Lake. (our lakes - if they were in the Northeast - would be called ponds) and we noticed that the water level is dangerously low. Since we aren't expecting much rain before August, I'm getting worried about water rationing. No mention of it yet. I guess I need to start considering using rainwater from the catchment tank. I've now got too much invested in the garden to let all the roses die of thirst.
