The good news is that hollyhocks are easy to grow flowers. They do have some specific requirements, but if the right growing conditions are met, these flowers will reseed themselves for years to come!

Hollyhocks need moist soil. They can be directly grown outdoors, a week or two before the last frost of the region, or you can start some seedlings at least three weeks before the last frost.

However, if you are following the second way, you should wait a week after the last frost to sow the seedlings outdoors!

All hollyhocks should be at least 2 feet apart from one another; this way they will all grow healthily, especially in zones 3-8.

Propagating Hollyhocks

Hollyhocks are self-seeding; this means that they will release some fertilized seeds into the soil, right before they die. Depending on the variety, some hollyhocks will release the seeds during the second year of life, that is why they are called biennial flowers.

On the other hand, other varieties of hollyhocks will only reseed themselves after the third year of life.

Fertilizer and Mulch

In fact, the soil should be amended before sowing hollyhocks. This could be easily done by adding a layer or two of mulch or compost. Ideally, you would place this at the beginning of spring.

Watering Requirements

If you live in an area where there are long periods of drought, then it is advisable to water them every other day, depending on their location.

Light Requirements

As stated previously, hollyhocks love the sun, full sun! However, the dwarf varieties of this plant should be placed in partial shade.

Many new gardeners will think that their hollyhocks have died because they look brown and dried during their first year. This is a normal behavior of hollyhocks, as they will tend to go like this during that time.

It is advisable to trim these areas and let them on the ground as mulch. Then, during the second and third years, these same hollyhocks will resurface healthier than ever before!
