Planting Hollyhocks
You can start hollyhocks from seed, either directly in the garden or indoors. Sow seeds about a week before the last frost or 9 weeks before in your area.
They love well-draining soil with full sun to some shade. Make sure to plant them 12 to 18 inches apart to give them room to grow.

Caring for Hollyhocks
Hollyhocks are easy to care for once they grow. But, following a few key steps helps them do well. Deadheading spent flowers stops too much seed production and keeps the garden neat. Also, cut the stalks back to the base after they finish blooming.
Slugs, snails, spider mites, and Japanese beetles can bother hollyhocks. But, rust is the most common disease I’ve seen. It can be prevented by watering correctly and keeping air moving around the plants.
In cold areas, hollyhocks might need to be grown as annuals. Start seeds indoors and bring them outside when it’s safe. In warmer places, cut the plants back and mulch them in the fall to protect the roots.
With a bit of care, hollyhocks can be a beautiful part of your garden. They bloom from June to August. Knowing what they need lets me enjoy these lovely flowers every year.
