You just grabbed your pruning shears to clean up the winter garden. You have 60 seconds before you destroy a nursery.
RIGHT NOW: 30% of native bees (like mason and leafcutter bees) are overwintering inside the hollow stems of last year’s dead flowers and berry bushes.
What happens: Silent. Fast. You cut the stalks down, bag them up, and throw this year's entire generation of pollinators into the municipal wood chipper.
What to do TODAY:
→ DO NOT cut back dead stems yet.
→ Wait until temperatures are consistently above 50°F (10°C).
→ When you do cut, leave 15 inches of the stalk standing.
→ New spring growth will quickly hide the old stems.
They spent the whole winter surviving the freezing cold. Don't let your spring cleaning be the thing that kills them.
Leave the stems. Every. Single. One.
