[Syngenta Flowers: Bertha™ White](https://www.syngentaflowers.com/ams/product/flower/70038580) ## Garden use and growing conditions Use the white blooms in sunny autumn borders or containers, where they brighten seasonal plantings. Garden mums grow best with at least six hours of direct sunlight and fertile soil that holds moisture without becoming waterlogged. The RHS also recommends chrysanthemums for borders, containers, and dedicated cut-flower plantings.

Container plants need regular moisture checks, especially in sunny or windy locations. In cold climates, spring planting gives garden mums more time to establish before winter; local hardiness varies among selections. ## Maintenance Keep soil evenly moist while allowing excess water to drain. Pinch young shoots in spring and early summer to encourage bushier growth, stopping by midsummer to allow flower buds to form.
