Hollyhock Chater tubers received 5 6 2022. The three roots looked good but felt like smashed spaghetti noodles. Called Breck’s customer service. Within a week I received three replacement roots in great condition.

Seed Germination: Hollyhock seeds can be tricky to germinate, requiring a cold stratification period before they will sprout. A 2-week cold stratification period chilling in the refrigerator.

Sowing: Hollyhock seeds prefer some light to germinate, so surface sowing is the way to get better results. Soaking seeds in warm water for 12 hours can help soften the tough seed coat and potentially improve germination rates before casting on bare soil. Gently press Hollyhock seeds into well-draining soil, keep soil consistently damp until germination.
