How to Grow and Care for Bare Root Perennials, Tubers, and Bulbs

Bare root perennials, tubers, and bulbs are an easy and economical way to jumpstart your garden with lasting beauty. These dormant plants should be planted in early spring or fall while the soil is cool and workable. Before planting, soak bare roots in water for 1–2 hours to rehydrate them. Choose a location based on the plant’s light needs—most flowering types prefer full sun, while others thrive in partial shade.

For bare root perennials, dig a shallow hole and spread the roots out naturally, ensuring the crown is level with the soil surface. For tubers and bulbs, plant with the pointed side facing up at a depth about two to three times their height. Cover with soil, gently press down, and water thoroughly.

Keep soil consistently moist (not soggy) until new growth appears. Add mulch to retain moisture and suppress weeds, but avoid covering the crown or bulb tops. Once established, these plants require little maintenance—just seasonal watering, occasional dividing, and deadheading or pruning as needed. With proper care, they’ll return and thrive year after year.
