to grow, and will flower the first year, if started early indoors. More often
though, they will bloom the second year. You will love the profusion of tall

Hollyhocks are natives of Asia. They have heart shaped leaves and bloom from
July to September in most areas. Tall Hollyhock flowers make great backgrounds,
borders, or even fences.

as high as 6 feet.
Hollyhock are often started from seed. You can sow Hollyhock seeds directly
into your flower garden. We recommend that you start them indoors six to
eight weeks before the last frost, and they may bloom the first year.
In the garden, they need plenty of room. Final spacing should be 18-24".
Give them plenty of room to allow air circulation and minimize rust and other
Established Hollyhock plants can be separated by division. This is best done
in the fall to allow the replants time to grow good roots in their new location

How to Grow Hollyhock Plants:
Hollyhock like full sun to partial shade. They will grow quickly to a height
of four to five feet or more, depending upon the variety you have selected
for your yard.
Hollyhock likes rich, well drained soil. Water as needed to keep the soil
moist at all times. Adding a general purpose fertilizer once a month will
result in bigger, fuller blooms.
After the growing season is over, Hollyhock should be cut back to ground
level. To assure that the plant doesnt get killed out completely, cover
the area with mulch, in case the winter is real harsh.
Flowers Bloom: Summer. A few varieties will bloom well into Fall.
Insect and Disease:
Insects problems are not too common and can be treated with insecticides
and insecticidal soaps.
Rust disease is a common problem. We recommend you apply fungicides regularly.
