Starting Morning Glories & Hollyhocks from Seed in Denver

Timing, Taproots, and Tricks for Success

Both have deep taproots—transplant once, early, or direct-sow.

When to Start

• Wait 4 weeks (late April) unless you have soil heating cables.
• Cool soil causes "damping off" (seedlings collapse at base).

Morning Glory Prep

1. Nick seed coat with razor blade.
2. Soak 2–4 hrs in warm water.
3. Sow 1–2 per pot.

Hollyhock Notes

• Start now for summer bloom; 2–3 weeks to germinate.
• Need warmth; soil cables help.
• If started now, may bloom first year.

Planting Out

• After last frost (early May), when nights ≥50°F.
• Deep holes for taproots—no root disturbance.
• Bell jars/plastic covers for first weeks.
