Do
- Grow in full sun and sharply drained soil.
- Prune hard every year or two in late summer or fall.
- Allow the plant to go semi-dormant during dry summer periods.
- Plant in poor, gravelly, or sandy soils to mimic its natural desert habitat.
- Prune lightly after flowering to maintain a rounded shape and remove dead wood.
Avoid

- Do not apply fertilizers, which cause weak and short-lived growth.
- Do not plant in heavy, poorly drained clay soils.

What goes wrong with Encelia
| Problem | What you'll see | What to do |
|---|---|---|
| Deer and rabbits | Clipped stems and chewed foliage, particularly on tender new growth. | Protect young plants with wire cages until they are established. |
| Aphids | Clusters of small insects on tender new growth, occasionally causing leaf curling on stressed plants. | Knock off with a sharp spray of water or allow native predatory insects to control populations naturally. |
| Aphids and spider mites | Distorted new growth, fine webbing, or stippled leaves during dry periods. | Blast pests off with a sharp stream of water or apply insecticidal soap if infestations are severe. |
| Snails and slugs | Irregular holes chewed in tender spring foliage and young stems. | Clear debris from around the base of the plant and hand-pick pests at night. |
| Root rot | Sudden wilting, yellowing leaves, and plant collapse, especially during warm summer months. | Ensure absolute drainage, avoid heavy soils, and eliminate summer irrigation. |
| Powdery mildew | White, powdery fungal growth on leaf surfaces, typically in humid or stagnant conditions. | Plant in full sun, provide adequate spacing for air circulation, and avoid overhead watering. |
| Stem fungal rot | Darkening and softening of the lower stems near the soil line. | Keep mulch away from the crown of the plant and avoid planting in heavy clay or waterlogged soils. |
