Springtime Sanctuaries: The Importance of Leaving Stems for Pollinators

In the delicate dance of spring’s arrival, our gardens hold secrets of renewal. Among them, the steadfast sentinels of last year’s growth stand tall – the perennial and grass stems. While their outward appearance may suggest dormancy, within their midst lies a bustling ecosystem.

Many insects, including beneficial ones like bees, butterflies, and ladybugs, overwinter in the hollow stems of perennials and grasses. These stems provide shelter from harsh winter conditions, protecting them until spring.

The uncut perennial and grass stems also serve as valuable nesting material for various bird species. Birds, especially those that build cup-shaped nests, such as finches and sparrows, often seek out these stems. They will gather and weave them into their nests, providing a secure and insulated environment for their eggs and fledglings.
