Asters, mums and heat
I'm wondering if anyone else has this problem?
September around here is a weird month temperature-wise. Temps can be all over the place and yes, I hate to say this, but our first traces of snow can fall this month. More often than not however, we get a good blast of summer heat for at least part of the month. Recently it's been in the 80's to low 90's for a couple of weeks with not a drop of rain in over a month and very low humidity. My early blooming mums and asters are not happy.
I've been keeping everything well watered, but many of the buds and flowers on the mums and asters simply dry up. The flowers that open look fried within a day or so. Temps are going to fall like a rock starting tomorrow with highs later in the week only in the 50's and 60's, but what do you do about the hot days or don't you have that problem? Maybe I should only grow later blooming varieties, but that can be tricky too since October can bring really cold weather and major snow.
