To provide a safe and prolific environment for pollinators, we recommend cutting back tropical milkweed (Asclepias curassavica) each September and October. Here’s why: when Tropical milkweed stays evergreen through winter, naturally occurring protozoa parasites build up on the plant. This protozoa occur on all milkweeds but are reduced when native Milkweed plants die back each fall. Tropical milkweed will not die back the same way as native species, which is why we recommend gardeners cut it back.
Divide the roots and rhizomes of perennials such as agapanthus, yarrow, and iris.
