About Garden Mum
Garden chrysanthemum (Chrysanthemum × morifolium) produces dense, daisy-like blooms in nearly every color in fall and winter. In NE Florida zone 9b, it is best used as a cool-season annual — plants cannot survive the intense summer heat and humidity and should be replanted each autumn for reliable color. Starting at $6.95.

Care essentials
Light
Grow in full sun to partial shade in NE Florida; afternoon shade reduces heat stress during fall establishment. Avoid full shade, which reduces flowering. In zone 9b, plant as a cool-season annual in fall.
Water
Water regularly to keep soil evenly moist but not saturated; do not allow to dry out between waterings. In NE Florida, plant in fall and enjoy through winter — plants will not survive summer heat and humidity.
Soil & Fertilizer
Plant in well-drained loamy soil amended with compost or peat; avoid heavy, waterlogged soils. Fertilize lightly at planting with a balanced slow-release fertilizer; excessive feeding promotes foliage over flowers. Replace plants each fall — do not expect perennial performance in zone 9b.
