🧑🌾 Step-by-Step Planting Instructions
Start Indoors (Recommended for all zones):
- Fill seed trays with moist, well-draining seed-starting mix.
- Sprinkle seeds on the soil surface. Do not cover. Light aids germination.
- Mist lightly. Cover with a clear plastic dome to retain moisture.
- Place in a warm area (65–70°F) with bright, indirect light.
- Remove dome once seedlings emerge (7–14 days). Keep soil moist.
- After 6–8 weeks, harden off seedlings over 5–7 days before transplanting outdoors.
Direct Sow in Spring (Recommended for all zones):
- In spring, after the soil is workable, prepare a well-drained bed in full sun.
- Sow seeds ¼ inch deep, spacing seeds 2–3 inches apart in rows.
- Water gently to keep soil moist until germination (7–14 days).
- After 3–4 weeks, thin seedlings to 18–24 inches apart.
- The plants will grow foliage in the first year and bloom the following spring.
Ongoing Care:
- Watering: Water regularly until established. Once mature, water only during prolonged dry spells. The plant is moderately drought-tolerant.
- Fertilizing: Do not fertilize. Hollyhock prefers poor soil and will produce more flowers when grown lean.
- Deadheading: Remove spent flowers to encourage a longer bloom period.
- Overwintering: In colder zones (3–5), provide a light mulch layer in winter to protect the roots. In milder zones, no protection is needed.
- Self-Sowing: Hollyhock will readily self-sow. If you do not want it to spread, deadhead before seeds form.
