Establishment
6-12 weeksYoung transplant with active root development and initial foliar growth
Water weekly for first 6-8 weeks if no rain, then taper frequency. Ensure excellent drainage to prevent root rot. Provide light afternoon shade in extreme heat (above 95°F) during first summer if possible.
Vegetative Growth
Several months to 1+ yearsPlant develops woody stems and foliage; slow to moderate growth rate
Minimal fertilizer needed; apply light balanced slow-release fertilizer in early spring only if planted in poor soil. Avoid high-nitrogen fertilizers. Prune lightly after flowering to maintain compact shape.
Pre-Flowering
4-8 weeks before bloomingPlant matures and prepares for bloom; flower buds form along stems
Reduce watering slightly to encourage flowering. Do not fertilize at this stage. Ensure full sun exposure for maximum flower production.
Flowering
8-12 weeks (spring and summer, can repeat in autumn in warm climates)Abundant tubular red flowers appear singly or in small clusters along stems; highly ornamental
Minimal intervention needed. Continue dry-side watering. Deadheading spent flowers encourages prolonged blooming but is optional. Enjoy pollinator activity.
Dormancy/Post-Flowering
Fall and winter, 3-4 monthsFlowering diminishes; plant enters slower growth period in cooler months
Reduce watering substantially. No fertilizer needed. Light pruning acceptable to remove dead wood or shape plant. Protect from frost in zones 9-9b.
