Seedling
2-3 weeksTiny rounded cotyledons emerge followed by true leaves with a soft, fuzzy texture. Plant is very delicate.
Keep soil consistently moist but not waterlogged. Provide bright light. Do not cover seeds heavily. Thin seedlings to prevent damping off.
Vegetative Growth
4-6 weeksPlant develops square stems (typical of mint family) with opposite, heart-shaped, gray-green leaves. Foliage becomes increasingly aromatic.
Water moderately. Ensure good drainage. Pinch back growing tips to encourage bushier growth. No fertilizer needed if planted in decent soil.
Budding
2-3 weeksFlower buds form at stem tips in whorled clusters. Plant becomes taller and more robust.
Continue moderate watering. Reduce watering frequency slightly. Do not overwater during this phase.
Flowering
6-12 weeks (can rebloom if deadheaded)Lavender, purple, pink, or white flowers bloom in dense spikes. Plant is highly attractive to pollinators and cats.
Deadhead spent flowers to encourage more blooms. Water only when soil is dry. Provide support if stems become tall and leggy.
Seed Production & Dormancy
4-8 weeks to full seed maturityFlowers fade and dry seed heads form if not deadheaded. In cooler climates, foliage dies back; in warmer zones, plant may remain semi-evergreen.
Allow some flowers to set seed for self-sowing or collect seeds when dry for storage. Cut back dead growth in fall or early spring.

Harvest Tips
Harvest leaves and flowers anytime after flowering begins for peak potency. Cut stems in the morning after dew dries. Pinch off top 1/3 of stems to encourage bushiness and prevent flowering if foliage harvest is the goal. For dried catnip, cut entire plant just as flowers open, bundle, and hang dry in warm, airy location. Store dried leaves in airtight container away from light.
