Seedling
2-3 weeksTiny seedlings emerge with two cotyledons and develop true leaves within 1-2 weeks. Growth is slow initially.
Maintain 70-75°F soil temperature. Provide bright indirect light. Keep soil consistently moist but not soggy. Avoid damping-off by ensuring good air circulation.
Vegetative Growth
3-4 weeksPlant develops multiple stems and foliage mass with increasing leaf production. No flowers yet but branching structure forms.
Pinch back growing tips when 2-3 inches tall to encourage bushiness. Transplant to larger containers as needed. Begin light fertilization with balanced NPK.
Pre-flowering
1-2 weeksPlant becomes fuller with visible flower buds beginning to form at branch tips. Bud break is imminent.
Switch to higher phosphorus fertilizer to encourage blooming. Ensure consistent watering and full sun exposure. Continue supporting shape if needed.
Flowering
6-16 weeks until frostMasses of pink petunia-like flowers blanket the plant, with 1-inch diameter blooms. Plant maintains dense flower production.
Fertilize every 2 weeks with balanced or flowering formula. Water consistently but allow top soil to dry between waterings. Remove any yellowing leaves. Self-cleaning variety requires minimal deadheading.
Decline (End of Season)
Variable, until first frostAs temperatures drop and days shorten in fall, flowering slows and vigor diminishes. Plant may become woody or leggy.
In frost-prone areas, prepare for plant termination or move containers to protected location. Can be overwintered indoors in cool climates but typically discarded. Collect seeds if desired before frost.

Harvest Tips
Calibrachoa 'Kabloom Pink' is grown for ornamental flowers rather than harvest. Deadheading is optional as the variety is self-cleaning. Pinch off spent flowers to encourage bushier growth if desired. To collect seeds, allow a few flowers to mature and dry on the plant; extract seeds when papery. Can be cut for short-lived fresh arrangements.
Fun Facts
- 🌱 Calibrachoa was first discovered and cultivated in South America (Argentina) and was only introduced to the ornamental plant market in the 1990s, making it a relatively modern garden flower.
- 🌱 The 'Kabloom' series was specifically bred for extra-large flowers and self-cleaning properties, meaning spent blooms drop naturally without deadheading, unlike many older calibrachoa varieties.
- 🌱 Despite resembling petunias, calibrachoas are genetically distinct and actually produce smaller flowers; the 'Kabloom Pink' cultivar is prized for having noticeably larger blooms than standard calibrachoas.
