Leave the Leaves!
The nights are getting down below freezing. Fall color has come and gone and leaves are falling fast. Our summer songbirds have been replaced by winter residents like dark-eyed juncos, golden-crowned sparrows, and hermit thrushes. The signs are inescapable – it’s time to start transitioning our gardens into winter mode.
Even though the sounds of leaf blowers are everywhere, there are some really powerful and compelling reasons to leave those leaves right in your garden. This fall, instead of bagging your fallen leaves and putting them out on the curb, consider raking them on top of your garden beds instead. Why?
- Creating a leaf much for your garden beds is the equivalent of tucking your plants in with a nice warm blanket. Mulched leaves help insulate plant roots against extreme cold snaps and are a great way to help insulate your perennials over the winter.
- Fallen leaves – and the dead stalks from this summer’s perennials - provide shelter for overwintering beneficial insects and pollinators (native bees, butterflies, etc.). These beneficials will more than repay you next year by helping to control any garden pests that might try to get established. Once cold weather has passed, you can prune back your perennials to get them ready for their spring growth.
- Your leaf mulch will break down within a few months; creating a free source of nutrients for your plants. Leaving the leaves is also a really simple way to introduce more organic material into your soil; something that’s beneficial to all soil types.
Finally, if you absolutely cannot stand to have leaves on your garden beds, this is a great time to start a compost pile. Add green trimmings, vegetable scraps, manure, and turn a few times over the winter and – voila! – you’ll have fresh rich compost ready for next spring’s growing season!
