Q.How Can I Stop Orange Flowers On My Butterfly Weed From Falling Off?
I planted butterfly weed in the spring of 2019. It came back very nicely this year. The green stems and leaves look very healthy and it producing a lot of orange flowers, but the flowers fall off after a couple of days. Do you know what can cause this?
