I noticed swamp milkweed, along the ditches of highways here, that are in bloom right now. Mine at home have long since bloomed and developing seed pods. The ones along the highway must have been mowed down earlier in the year. It got me to wonder how I could deadhead my milkweeds to keep them blooming more.
Has anyone got experience doing this, and with which species?
) mentions "With early seed pod removal, some Asclepias will rebloom."
When would a milkweed need deadheaded? Just the expired blooms? or possibly the whole branch holding the blooms?
