Hiya chicky. Well, echinaceas are cut back bit earlier really but did one or two fortnight back. When I buy any I always remove flower stems, even now, but no later than another week or so. I bought echinacea milkshake and summer sun 3 weeks ago, cut off the would be flower stems and they are now showing their new buds. Shorter, stockier but should flower for lomg time. I find they need a reasonable supply of moisture too.....I know they are "prairie" plants but they have become so hybridised they aren't so adept at surviving and flowering....in my opinion. So chicky, I would water a little....they will prob flower next month.
I don't cut back for second flush on echinaceas. I do it for a better, longer flowering period in mid to late summer.
