• Can also be sown in February in cooler Gulf areas.
• Avoid sowing during the hottest summer months.

Seed Preparation

• No soaking is required.
• Optional: Soak seeds in lukewarm water for 6–8 hours before sowing to improve germination.

Soil Preparation

Hollyhocks prefer deep, fertile, well-drained soil rich in organic matter.

Recommended mix:

• 40% Sandy garden soil
• 30% Well-rotted compost
• 20% Coco peat

Ideal soil pH:

• 6.5–7.5

Sowing Method

• Sow seeds in seed trays or directly into prepared soil.
• Plant seeds 0.5–1 cm deep.
• Cover lightly with fine soil.
• Keep the soil evenly moist until germination.
• Transplant seedlings when they have 3–4 true leaves, taking care not to disturb the roots.

Temperature & Light

• Ideal germination temperature: 18–22°C
• Ideal growing temperature: 15–28°C
• Requires 6–8 hours of direct sunlight daily.
• In the Gulf, light afternoon shade during warm spring weather helps extend flowering.

Watering

• Keep the soil lightly moist during germination.
• Once established, water deeply when the top 3–5 cm of soil becomes dry.
• Avoid waterlogging while maintaining consistent moisture during flowering.

Germination Time

• 10–21 days

Plant Spacing

• 45–60 cm between plants.
• 60–75 cm between rows.

Flowering

• Flowers usually appear 4–6 months after sowing under Gulf cool-season conditions.
• Remove faded flowers regularly to encourage prolonged blooming, or leave some flowers for seed production.

Fertilization

• Mix compost into the soil before planting.
• Feed every 4–6 weeks with a balanced flowering fertilizer.
• During bud formation, use a fertilizer slightly higher in potassium to promote abundant blooms.
• Avoid excessive nitrogen, which encourages foliage instead of flowers.

Gulf Climate Tips

• Grow during the cool season only.
• Water early in the morning.
• Apply mulch to keep roots cool and conserve moisture.
• Support tall flower spikes with stakes if exposed to strong winds.
• Ensure good air circulation around plants.
