Prolonging flowering this autumn - Asters and crysanths and roses
Hello, I planted Asters (Lazy Daisy variety) and Crysanthamums, hoping they might keep going until mid October to use at our wedding. They still look great and I have some new buds still coming as I sowed some at different times. My question is, is there anything I can do to help maximise flowers for 3 weeks' time? I am deadheading them regularly as the petals start to droop. But wondered if it was worth risking anything more drastic - eg cutting back flowers which still look good at the moment to make more buds form. Obviously I know if we get a hard frost they could be done for!
I also have a rose bush - no idea of the variety sorry - and that is still flowering and some new buds still coming. I have been deadheading very regularly but again wonder if I cut off all the flowers now might that help more buds form?
I've also got Orlaya, Verbena Bonariensis, Nasturtiums and California Poppies which seem to all be lasting very well at the moment.
Grateful for any tips. I normally grow veg on my allotment but turned some of it over to flowers this year, so new to this!
