Growth Stages

Seedling

2-3 weeks

Tiny seedlings with first true leaves emerging; very delicate and small

Keep soil moist and provide bright, indirect light. Maintain warm temperatures (70-75°F). Avoid overwatering to prevent damping off.

Vegetative

3-4 weeks

Plant develops multiple stems and foliage; shoots elongate and spread horizontally

Pinch growing tips early to encourage branching. Gradually increase light and air circulation. Begin fertilizing weekly with balanced, water-soluble fertilizer.

Pre-flowering

2-3 weeks

Visible flower buds form at stem tips; plant reaches desired trailing length

Continue regular watering and fertilizing. Shift to slightly lower nitrogen fertilizer to encourage blooming. Ensure full sun exposure.

Flowering

8-12 weeks

Profusion of small, delicate flowers covering the trailing stems; continuous bloom

Maintain consistent moisture and weekly fertilizing with bloom-boosting formula (higher phosphorus). Deadhead spent flowers if desired, though not necessary. Provide full sun for maximum blooms.

Peak bloom & decline

4-8 weeks

Maximum flowering in mid-season; natural decline as temperatures drop or season ends

In perennial zones, cut back severely in fall or overwinter indoors. For annuals, enjoy blooms until frost then compost.
