What type of BUTTERFLIES are you trying to attract?
Monarchs, Swallowtails, Eastern Tailed Blue
What NECTAR and HOST plants are in your garden?
Butterfly Bushes for nectar and I did have several butterfly weed plants that did house cocoons last year, but I do not see it returning this year. It is possible that is was weeded or it hasn’t started yet do to this spring’s weather.
