Catmint20906 said:I had the same experience with my 'Ogon' last year--it kept petering out; I tried both full and part sun. This year, I have it nestled under the viburnum and a large azalea, where it probably gets a little dappled sun but mostly shade. It's finally doing well.
valleylynn said:Ofm, here in the PNW we don't need to water them, except maybe once or twice in the months of July, August and Sept. Unless it rains, then I won't water them at all during those months. But we seldom get any rain in Aug, and even Sept. And they need full sun. Mine are all still upright and alive and well. The leaves are starting to turn to the fall coloring with the cooler weather and shorter daylight.
valleylynn said:The first year I do water them and keep them in a state of growing well. Once established they seem to do very well in very little care. This is the tall upright ones.
I think withholding water causes them to send their roots deeper.
Here is a photo taken today. Full sun, almost no water this summer, once in July, once in August, none in Sept or Oct. Deep, fast draining sandy loam compost. All of them have started going into dormancy in the last week. It has turned cold her at night, but as you can see they are still standing upright with no support, had nice foliage until heading into dormancy.
I will leave the seed stalks until spring, when the new growth starts popping through the soil.
