Growth Stages

1

Establishment

2-4 weeks

Young plants are tiny with sparse foliage and delicate stems beginning to creep outward

Keep soil consistently moist but not soggy. Protect from strong wind and direct hot sun. Begin in spring for best establishment.

2

Vegetative Growth

4-8 weeks

Plant develops a dense network of creeping stems with numerous small, rounded leaves forming tight mats

Water regularly during dry spells. Pinch back stems occasionally to encourage bushier growth. Ensure good drainage to prevent root rot.

3

Flowering

8-12 weeks (spring to early summer)

Delicate white, pale blue, or purple flowers appear on short stalks above the foliage; blooms are small but abundant

Maintain consistent moisture. Deadhead spent flowers to encourage continued blooming. Feed with balanced fertilizer if soil is poor.

4

Summer Rest

2-3 months

Growth slows in intense heat; foliage may appear stressed or less vibrant in extremely hot conditions

Increase watering frequency in hot climates. Provide afternoon shade in zones 9-10. Mulch lightly to keep roots cool and moist.

5

Winter/Dormancy

3-4 months

Plant slows growth; foliage remains green but growth nearly stops; some varieties may show bronze or purple tinges

Reduce watering significantly. Ensure drainage is excellent to prevent winter rot. Mulch in zones 7-8 for frost protection.
