Companion planting is an ancient gardening technique that involves growing different plants close to each other for mutual benefit. When it comes to milkweed, a vital plant for monarch butterflies, choosing the right companions can enhance growth, improve pest resistance, and support local ecosystems. This article explores the best companion plants for milkweed and how they work together to create a thriving garden environment.
Understanding Milkweed and Its Role in the Ecosystem
Milkweed (Asclepias spp.) is a hardy perennial known for its milky sap and striking flowers.
