Hey there...my very first post, so go easy!
I planted two kinds of Monarda two years ago, one of them was Squaw. Apart from powdery mildew, they were great - tall elegant stems and lots of flowers.
That winter they died back as expected, butI noticed that small, scrubby foliage persisted. I presumed this would spring back into the same tall growth as the previous spring. It didn't. It remained fairly scrubby and didn't get much more than a foot and a half tall.
Can anyone suggest why? I had just put in an irrigation system prior the second spring - I wondered if too much water may have caused it. For the first year I had bought lots of organic compost and turned it into the soil, but not for the second year. Could it be a fertiliser thing?
