Everything it needs
9 essentials at a glance
Watering
Gaillardia aristata prefers moderate watering.
Water the plant when the top inch of soil feels dry, typically every 1-2 weeks. In hotter months, increase frequency to weekly. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and browning leaf edges.
Light
This plant thrives in full sun, requiring at least 6-8 hours of direct sunlight daily.
Ideal placements include south-facing gardens or patios. It can tolerate partial shade but may produce fewer flowers in such conditions.
Soil
Gaillardia aristata prefers well-draining soil with a pH range of 6.0 to 7.0.
A sandy or loamy potting mix is recommended to ensure proper drainage and aeration. Avoid heavy clay soils that retain moisture.
Humidity
This plant prefers low to moderate humidity levels, ideally around 40-60%.
To increase humidity, mist the leaves or place a humidity tray nearby. Signs of humidity stress include leaf curling and browning tips.
Temperature
Gaillardia aristata thrives in temperatures between 70-85°F (21-29°C) and is hardy in zones 3-10.
It can tolerate brief periods of heat up to 95°F (35°C) but may struggle in extreme cold below 20°F (-6°C).
Fertilizing
Use a balanced fertilizer with an NPK ratio of 10-10-10, applying every 4-6 weeks during the growing season.
Reduce feeding in late summer. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Prune Gaillardia aristata in early spring to remove dead or damaged stems.
Use sharp, clean pruning shears for a clean cut. Deadheading spent flowers throughout the blooming season encourages more blooms and maintains plant health.
Repotting
Repot every 2-3 years or when the plant becomes root-bound.
Choose a pot 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of drainage holes and stunted growth. Follow by gently removing the plant, refreshing the soil, and placing it in the new pot.
Propagation
Propagation can be done through seeds or division.
For seeds, sow in spring after the last frost, covering lightly with soil. For division, dig up established plants in early spring or fall, and separate the root clumps, replanting immediately.
