Growth Stages

1

Germination

7-14 days

Tiny seedlings emerge with cotyledons (seed leaves) appearing within 7-10 days

Keep soil moist and maintain temperatures of 60-70°F. Provide bright light once seedlings emerge. Avoid high heat.

2

Seedling

3-4 weeks

Young plants develop 2-4 true leaves and grow slowly, establishing a compact root system

Thin seedlings to proper spacing. Provide bright light, keep soil moist, and maintain cool conditions. Begin fertilizing at half strength.

3

Vegetative Growth

4-6 weeks

Plant develops robust stems and foliage, becoming bushier with continued leaf development

Pinch growing tips when plants are 4-6 inches tall to encourage branching and more flower spikes. Maintain consistent moisture and cool conditions. Fertilize every 2-3 weeks.

4

Budding and Flowering

6-8 weeks or longer

Dense flower spikes emerge at stem tips, progressively opening from bottom to top with abundant fragrant blooms

Support tall varieties with stakes or cages. Deadhead spent flowers to encourage continued blooming. Maintain cool temperatures (60-70°F) for longer flower life. Water at soil level to keep foliage dry.

5

Seed Production (optional)

4-6 weeks

Flowers fade and develop seed pods if not deadheaded; seeds mature within pods

Allow select flowers to remain for seed collection. Once pods brown and dry, harvest and store seeds in cool, dry conditions. Remove spent plants.

Common Pests

  • Ensure good air circulation, avoid overhead watering, remove infected leaves, apply fungicides if needed

  • Improve air circulation, spray with sulfur or neem oil, maintain proper spacing, reduce humidity

  • Use row covers, hand-pick larvae, apply Bt (Bacillus thuringiensis), plant companion herbs like thyme

  • Use row covers on young plants, spray with neem oil, maintain good plant health

  • Increase humidity, spray with water, apply neem oil or miticide if severe

Harvest Tips

Harvest stems when the bottom 1/3 of the flower spike is open for longest vase life. Cut in early morning when stems are fully hydrated. Recut stems at an angle, remove lower foliage, and place immediately in cool water. Change water every 2-3 days. Lasts 10-14 days in a vase. For continuous outdoor color, allow some flowers to remain on plant rather than cutting all stems.

Fun Facts

  • 🌱 Stock flowers are named from the Old French word 'estoc' meaning a wooden stake or stem, referring to their sturdy, upright growth habit.
  • 🌱 Stock has been cultivated for over 2,000 years and was highly prized in Victorian gardens for both its fragrance and ornamental beauty.
  • 🌱 Double-flowered varieties (with more petals) are preferred ornamentally but are sterile and cannot produce seeds, so they must be propagated from cuttings.
