Seedling
3-4 weeksTiny seedlings with 2-4 true leaves, still compact and delicate
Maintain warm temps (70-75°F), bright indirect light, consistent moisture. Mist lightly to prevent drying. Provide air circulation to prevent damping off.
Vegetative Growth
3-4 weeksPlant develops multiple stems and foliage, beginning to form a bushy or cascading habit
Pinch back growing tips early to encourage branching and fuller shape. Provide full sun and begin light fertilizing. Maintain consistent watering and moderate moisture.
Pre-flowering
2-3 weeksPlant reaches desired size with visible flower buds forming at stem tips
Continue pinching if needed for bushier form. Increase fertilizer frequency (weekly feeding). Ensure consistent watering and full sun exposure.
Flowering
8-12+ weeks (until frost)Abundant small velvety dark purple flowers open continuously along cascading stems
Deadhead faded flowers to encourage continuous blooming (though Surfinia varieties are self-cleaning). Water deeply and regularly. Feed every 1-2 weeks with balanced or bloom-boosting fertilizer. Watch for pests.
End of Season
4+ weeksFlowering slows and plant deteriorates as temperatures cool or frost approaches
Can be brought indoors in zones 8 and below before first frost if desired. Otherwise, allow to naturally senesce. In zones 9-11, prune back in fall and allow to rest for winter.
