Common problems

Root rot — Overwatering can lead to root rot, especially in poorly draining soil.
Spider mites — These tiny pests can infest plants in dry conditions, causing stippling on leaves.
Aphids — Small, sap-sucking insects that can weaken the plant and distort new growth.

Growing it

Propagation: Cuttings, Seed
When to plant: Spring, Summer
Overwintering: In regions with frost, treat Scaevola aemula as an annual. If you wish to overwinter it, bring container plants indoors before the first frost to a bright, cool location and reduce watering. You can also take cuttings in late summer to start new plants indoors.
In containers: Excellent for containers, hanging baskets, and window boxes; a minimum pot size of 6 inches is recommended for good growth.

Seed

Sow seeds indoors 6-8 weeks before the last frost.
Cover seeds lightly with a fine seed-starting mix.
Keep soil consistently moist and warm (70-75°F / 21-24°C).
Provide bright light once seedlings emerge.
Transplant seedlings outdoors after the danger of frost has passed.

Cuttings

Take 3-4 inch cuttings from healthy, non-flowering stems in spring or summer.
Remove the lower leaves and dip the cut end in rooting hormone.
Insert cuttings into a moist rooting medium, such as perlite or a seed-starting mix.
Keep cuttings in a warm, bright location and maintain moisture.
Roots should form within 3-4 weeks; transplant as needed.

Pair Scaevola with plants that enjoy full sun and well-draining soil for a cohesive and beautiful garden display.

Grows well with

Petunia — Both thrive in full sun and similar well-draining soil, creating a vibrant display together.
Lobelia — Lobelia complements the fan flower with its delicate blue or white blooms and similar moisture needs.
Marigold — Marigolds add bright, cheerful colors and can help deter some pests when planted nearby.
Bacopa — Bacopa's trailing habit and small flowers provide a lovely contrast and groundcover effect.

Keep away from

Mint — Mints can be very aggressive spreaders and may outcompete the slower growing Scaevola for resources.
Vinca — While also a groundcover, Vinca can spread rapidly and potentially smother smaller plants.
