Planting Details
| Seed Depth | Press into surface |
|---|---|
| Seed Spacing | A group of 3 seeds every 24"–36" |
| Thinning | When 3" tall, thin to 1 every 24"–36" |
| Germination | 10–14 days |
| Start Indoors | 6 to 8 weeks before your average last frost date. Roots are sensitive to disturbance; sow in biodegradable pots that can be planted in the ground. |
| Direct Sow | RECOMMENDED. 1 to 2 weeks after your average last frost date, or 2 months before your average first fall frost date. |
| Growing & Harvesting | For longest-lasting cut flowers, harvest when 1/3 of the flowers on the stem have opened. Harvest in the morning; cut stem at an angle and immediately place in a bucket of warm water. Before placing in a vase, dip the stem end in boiling water for a minute, or sear it over a flame for 20 seconds; this will stop the flow of the milky sap so it does not clog the stem. |

Writing a separate review for spring planted - I planted Indian Spring hollyhocks in early May 2024 and they were putting out flowers as late as October. Beautiful dark pink color. Needed some vertical support since they fell over a couple times.

I planted in August and my seeds had a low survival rate. The one that didn't die bloomed beautifully the following June.
