Hello everyone.. I am new to this site, so I do not really know what I am doing yet. Can anyone help me? I have had butterfly bushes for the last 5 years. They have grown beautifully. This year all 3 of them died (or have seemed to) They are spaced about 20 ft. away from eachother in a ^ formation.
I have no idea what has happened. I live in zone
5. They have braved all the harsh winters before. I cover them with mulch every winter, but this spring
nothing happened. All my other plants in the flower
garden are fine. Just the butterfly bushes. I usually cut them down to about 1 1/2 ft. each year.
Please HELP :(
