What Is Yarrow?
Yarrow (Achillea millefolium) is a hardy perennial known for its feathery leaves and clusters of small, colorful flowers. It has been used for centuries in traditional medicine and as a natural pest deterrent. Yarrow attracts beneficial insects and improves soil health, making it an excellent companion plant.

Marigolds as Garden Protectors
Marigolds (Tagetes) are vibrant annuals renowned for their pest-repelling properties. Their strong scent confuses and deters nematodes, aphids, and other common pests. Marigolds also attract pollinators, aiding in the pollination of nearby plants.
