Timing

• Sow hollyhock seeds in late winter to early spring (indoors) or late summer to autumn for spring/early-summer blooms the following year (biennial habit).

Seed Preparation & Sowing

• Surface sowing: Hollyhock seeds benefit from light — press seeds lightly onto the soil surface and do not bury deeper than 2–3 mm.
• Tray or direct sow: Start in seed trays with a free-draining seed mix (50% fine compost + 50% coarse grit or perlite) or sow directly in a prepared bed.
• Stratification (optional): A short cold period (2–3 weeks in fridge) can improve germination for some strains, but isn’t mandatory with Alkarty seeds.
• Germination: Expect 7–21 days at 18–22°C. Keep the surface evenly moist but not waterlogged.

Transplanting & Spacing

• When seedlings have 3–4 true leaves, harden off for a week and transplant outdoors after frost risk. Space plants 45–60 cm apart to accommodate tall flower spikes.

• Staking: Tall flower spikes can need support in windy sites. Use stakes or plant supports early to avoid root disturbance.
• Pinching & Deadheading: Remove spent flowers to encourage further bloom on side shoots. In biennial habit, allow some seed set if you want natural reseeding.
• Pest & Disease Management: Common issues include rust (Puccinia malvacearum) and occasional aphids or slugs. For rust, remove and destroy infected leaves, improve air circulation, and avoid overhead watering. Use organic controls (neem oil, insecticidal soap) for pests.
• Crop Rotation & Hygiene: Avoid planting hollyhocks in the same spot year after year if rust has been a problem. Clear and compost (or dispose of) old foliage at season end.
• Propagation: Save seed from mature pods, or propagate by basal cuttings or division where applicable.
