Country Fence Row Hollyhocks

Hollyhock prefers full sun and well-drained soil with plenty of organic matter. It does best in a slightly acidic soil with a pH of 6.0-7.0. It is drought tolerant but will need regular watering during dry spells. It also benefits from a layer of mulch to help retain moisture.

Sow seeds in full to part sun one week before last frost.  Ample airflow is necessary to minimize disease.  Once established, plants should be spaced at least 18" in all directions. Alternatively, start seeds indoors, harden off and set outdoors after danger of frost has passed.

Space plants at least 18" in all directions. After danger of frost has passed, dig a hole roughly the size of the root ball and lower the seedling in. Water the plant deeply after transplanting and keep well-watered until it is established.

Although generally easy to care for, Hollyhock is susceptible to powdery mildew, rust, and other fungal diseases. Be sure to give plants ample space to promote airflow and limit disease.

Hollyhocks can make excellent cut flowers provided the stem scars are prepped before arranging. They have long, sturdy stems and large, colorful blooms that last for several days in a vase. They also have a pleasant, sweet scent that adds to the beauty of any floral arrangement.

CONSIDERATIONS:

Hollyhocks can cross pollinate so it is important to isolate different varieties if saving seed. To harvest hollyhock seeds, wait until the seed pods turn brown and dry, then cut them off the plant and place them in a paper bag. Shake the bag to release the seeds, then store them in a cool, dry place.
