Homeowner Growing & Maintenance

Alcea is easy to grow and adapts to most conditions. Feed once a year with a slow release fertilizer. To give your plant the best start possible, we include free fertilizer with every order.

Interesting Notes

Hollyhocks can be grown under Black Walnut trees; they are tolerant of the toxic juglone that is emitted through the trees roots.
