Germination
7-14 daysTiny seedlings emerge with small oval cotyledons and fine hairs becoming visible within 7-14 days.
Keep soil consistently moist but not waterlogged. Provide light exposure for seed germination. Thin seedlings to prevent crowding.
Seedling/Vegetative
2-4 weeksHairy, heart-shaped leaves develop on low-growing stems. Plant remains compact with a rosette or trailing form.
Maintain moderate soil moisture. Remove competing weeds. Begin fertilizing lightly with balanced fertilizer if growing for culinary use.
Growth & Spreading
3-6 weeksStems elongate and may root at nodes where they contact soil. Dense mat forms with multiple growth points.
Monitor for pest colonization. Prune or thin if crowding occurs. Water moderately; avoid overhead watering to prevent fungal issues.
Flowering
4-8 weeksSmall white flowers (4-8mm) with notched petals appear in terminal clusters above the foliage. Blooms begin in spring and continue intermittently.
Flowers attract beneficial insects. Deadhead spent flowers to encourage continued blooming. Reduce nitrogen fertilizer to promote flowering over leaf growth.
Seed Production & Senescence
4-6 weeksSmall capsule fruits develop containing numerous tiny seeds. Foliage may decline in summer heat or persist into winter depending on climate.
Allow some flowers to mature if self-seeding is desired. Harvest seed heads before they fully dry and disperse. Remove spent plants after seed set.
