Chrysanthemum Growing Guide for Zone 9

Planting Time: In Florida, plant chrysanthemums in early spring or fall. Chrysanthemums thrive in cooler weather but can tolerate the heat of summer, making them suitable for both spring and fall planting.

Soil: Chrysanthemums prefer well-draining soil with a pH between 6.0 and 7.0. Adding compost or well-rotted manure to the soil can improve fertility and structure.

Sun: Chrysanthemums grow best in full sun, requiring at least 6-8 hours of direct sunlight daily.

Watering: Keep the soil consistently moist but not waterlogged. Water regularly, especially during dry spells, to keep the soil evenly moist.

Spacing: Plant chrysanthemum seeds or transplants 18-24 inches apart. Chrysanthemums can spread, so proper spacing ensures adequate air circulation and room for growth.

Fertilization:
N-P-K Ratio: Chrysanthemums benefit from a balanced fertilizer with a slightly higher phosphorus content to support strong root and flower development, such as 5-10-10 or 10-10-10.

When to Add:

• Before Planting: Apply the fertilizer to the soil before planting seeds or transplants to promote strong initial growth.

• Early Spring: Reapply the fertilizer in early spring as new growth begins.

• Mid-Growing Season: Reapply the fertilizer every 4-6 weeks during the growing season to support continued growth and blooming.

Application Tips:

• Follow the directions on the fertilizer package to avoid over-fertilization.

• Apply the fertilizer evenly around the base of the plants and water thoroughly to help the nutrients reach the roots.

Additional Tips:

• Chrysanthemums grow best in well-drained soil rich in organic matter, so consider adding compost to improve soil fertility and structure.

• Mulch around the plants to help retain moisture, suppress weeds, and regulate soil temperature.

• Ensure that chrysanthemums receive consistent moisture, especially during flowering, to prevent stress and promote abundant blooming.
