WHEN and HOW to clean up the winter wildlife garden is a question I am often asked. My advice:
- Wait until you have a stretch of warm days (not a warm day here and there)
- Don’t tackle this task with a rake, but instead break off stems and seed heads, looking for life on them as you go (butterfly chrysalis, moth cocoon, Carolina Mantis egg case, etc.). If stems do not break off easily, cut them at the base, otherwise you may pull out the roots and lose these gem pollinator plants (like Anise Hyssop, Verbena bonariensis, and a few others). Collect these broken off stems and seed heads and transport them to a border of your property or your woods. Scatter them loosely, single-layer so overwintering insects can still complete their life cycle (because, believe me, there is hidden life you will not “spot” on those broken off stems and seed heads).
- Do not remove your old mulch but instead leave it in place, especially if it is salt hay or another organic mulch like leaves, grass clippings, or pine stray / pine needles, since these organic mulches will break down into soil
- wait to put new organic mulch down for a while until more and more of your perennials come up and you can see where they are.
Spring cleaning, if done with wildlife in mind, is a slow process. On hands and knees each section is tackled slowly enough to spot garden treasures (overwintering chrysalises on stems, partially grown caterpillars in curled up leaves, microscopic eggs on plant material). Each spring many treasures are found along the way: spider egg sacks (some intact, others that had been discovered by hungry birds and emptied sometime over the winter), Carolina Mantid egg cases, and plant stems that have been nibbled to the core (proof that the garden’s dormant insects aided wintering birds).
