Last year I planted a bed of fall mums to impress my book club at a lonely bed near our property entrance. Come spring I was surprised to see their little shoots peeking up. This fall they are even more beautiful than last year. What a surprise to receive an instant fall bed without any work except weeding over the summer! A great investment and according to the article I did exactly as I should have - all by accident.
Mum flowers always seem like a surprise and a gift -- I think it's because we have a tendency to pay no notice to the plant all summer long, but when it blooms -- wow. The conditions must be exactly what your mum likes. Happy autumn!
