Seedling
2-3 weeksTiny seedlings emerge with small cotyledons; plants are delicate and low to ground
Keep soil consistently moist but not waterlogged. Thin seedlings to proper spacing early. Provide bright light to prevent stretching.
Vegetative Growth
4-6 weeksPlants develop true leaves and establish bushy foliage; stems become stronger and more woody
Water moderately and allow soil to dry between waterings. No fertilizer needed if soil is amended with compost. Pinch tips to encourage bushier growth if desired.
Flowering
4-6 weeksDense spike-like flower clusters appear, typically purple or white depending on variety; flowers attract pollinators
Continue moderate watering. Do not fertilize during flowering as excess nitrogen reduces seed production. Ensure good air circulation.
Seed Development
3-4 weeksFlowers fade and are replaced by tiny seed pods containing the characteristic small, speckled seeds
Reduce watering gradually; allow plants to dry out as seeds mature. Avoid overhead watering to prevent fungal issues.
Harvest Ready
Until harvestSeed pods dry and turn brown; seeds are hard and fully mature, ready for collection
Stop watering. Allow plants to fully dry. Harvest when seed pods are completely brown and seeds don't indent when squeezed.
Common Pests
-
Spray with water to dislodge; use neem oil if infestation persists. Maintain humid conditions to discourage mites.
-
Spray with strong water stream or insecticidal soap. Encourage natural predators like ladybugs.
-
Use yellow sticky traps; spray with neem oil or insecticidal soap if needed.
