Growth Stages

1

Seedling

2-3 weeks

Tiny cotyledons emerge within 5-10 days; first true leaves follow shortly after.

Keep soil warm (70-75°F) and consistently moist. Provide bright indirect light. Thin seedlings to proper spacing once true leaves appear.

2

Vegetative

3-4 weeks

Plant develops bushy growth with multiple stems and increasingly fragrant leaves. Compact, dense foliage forms.

Pinch off top growing tips regularly to encourage bushiness and prevent early flowering. Provide consistent warmth and full sun. Begin harvesting outer leaves once plant has 6-8 leaves.

3

Flowering

Ongoing throughout season if left unpruned

Small white to pale purple flower spikes appear at stem tips. Leaves begin to thin as plant energy shifts to reproduction.

Pinch off flower buds as soon as they appear to extend the leafy harvest period and maintain tender foliage flavor. Remove entire flower spikes at the stem.

4

Leaf Production (Maintained)

4-8 weeks or until frost

With regular pinching, plant continues producing fresh, tender leaves throughout the season.

Harvest frequently (2-3 times per week), removing leaf clusters from the top. This stimulates more branching and keeps plant productive.

5

Decline/Frost Sensitivity

Variable, depends on climate

Plant slows or stops growing as temperatures drop below 50°F; leaves may wilt or blacken with frost exposure.

In cool climates, bring containers indoors or cover with frost cloth. In zones 10-11, plant may recover and regrow. End-of-season harvest before first frost.

Harvest Tips

Begin harvesting once the plant has 6-8 leaves (about 3-4 weeks from transplant). Pinch off the top 1-2 inches of growth, including leaf pairs, to encourage bushiness. Harvest frequently (2-3 times weekly) to maximize production and keep leaves tender. Remove flower buds as they appear to extend the harvest season. For best flavor, harvest in the morning after dew dries. Use fresh immediately or freeze in oil for later use.

Fun Facts
