Growth Stages

1

Seedling

2-3 weeks

Tiny leaves emerge, plant remains compact and low. Very delicate at this stage.

Keep soil lightly moist, provide bright light, avoid overwatering. Thin seedlings to 3-4 inches apart.

2

Vegetative

4-8 weeks

Plant develops dense mat of fine, narrow leaves. Growth is slow but steady, remaining prostrate or mounding.

Water sparingly, ensure excellent drainage. Begin pinching back tips to encourage bushiness.

3

Flowering

6-10 weeks

Red, crimson, or magenta flower spikes emerge above foliage. Flowers are small and densely packed on short stems.

Deadhead spent blooms to encourage continued flowering. Reduce nitrogen feeding to avoid excessive leaf growth.

4

Peak Production

Throughout growing season

Plant reaches mature size (4-6 inches tall, 12+ inches wide), covered with foliage and recurring flower clusters.

Harvest leaves regularly for culinary use. Prune after flowering to maintain shape and promote dense growth.

5

Dormancy/Winter

3-4 months

Plant remains evergreen but growth slows. Foliage may take on purplish or bronze tones in cold weather.

Reduce watering, allow soil to dry. Do not fertilize. Provide excellent drainage to prevent root rot in wet winters.
