Certain seeds benefit from being grown indoors in containers, such as those that need extra warmth to sprout or grow well, annuals that need a long growing season to bloom well, perennials that may bloom the first summer if given a head start, and summer sowings of perennial seeds.

Starting Spring Seeds Indoors: 

Germinating Hollyhock Seeds:
1) Fill seed starting trays to within 1/4 to 1/2 inch of the rim with moist soil mix.
2) Firm the surface with the back of your fingers, then scatter 2-3 seeds evenly over the medium.
3) Sprinkle a little additional soil mix over seeds until they are covered 1/8" add a label with the plant name and date.
4) Cover the finished pots with plastic and set them in a warm bright place or under lights at a room temperature of 65 degrees Fahrenheit .  
5) Keep the soil moist as the seedlings sprout and develop. Move the pots into direct sunlight to continue growing.

Temperature: 60 - 65F. 
Average Germ Time: 21-28 days
Light Required: Yes
Depth: Do not cover the seed but press into the soil
Moisture: Keep seed moist until germination

Transplanting Seedlings into Larger Pots:
1) When your seedlings have two sets of true leaves, pot them up into a larger container filled with a soil mix.
2) After the last threat of frost, harden off the seedlings in the garden for about 10 days.
3) Once the seedlings have been hardened off, you can plant them in the garden.

Spring Planting Outdoors:
Hollyhock seeds can be directly sown in the spring time after the last frost date. Direct sow 2-3 seeds 1/8" deep, 24" apart in any moist 
soil that is well-drained with pH 6.0 - 8.0. The prefer to be planted in an area in full sun.

Fall Planting: 
In late fall (
August or September), direct sow 2-3 seeds 1/8" deep in any moist soil that is well-drained with pH 6.0 - 8.0.
​How:
​Transplant your seedlings into the garden once the soil has warmed after all dangers of frost. Hollyhock prefers full sun and a moist soil that has a pH  between 6.0 and 8.0. Dig your holes as deep as the pots you are transplanting from and keep a spacing of 24" between seedlings. Your soil will need to maintain a medium moisture until your hollyhocks develop its taproot.

When outdoor temp: 60˚F to 90˚F.
​
Spacing: 24"
​
Support: No.

Water: Water daily for the first few weeks after planting, and regularly after that, keeping the soil is moist but not waterlogged. Once hollyhocks grow to maturity, they become relatively drought-tolerant, so you can then decrease your watering frequency to two to three times per week for the rest of the growing season

Temperature and Humidity: Hollyhocks grow in a temperature range of 60-90º F as long as conditions are ideal. If the temperature drops below 55º F, it will die back to the ground, and you will need to mulch the soil in order to insulate the dormant roots to protect them from getting too cold. Hollyhocks don't have any humidity requirements and actually fare worse in climates with high humidity as this makes them more susceptible to diseases such as rust. Hollyhocks need good air circulation, so enable this by planting them around 18 inches apart.

Fertilizer: Hollyhock flowers do well with 10-10-10 fertilizer, which, in short, stands for equal levels nitrogen, phosphorus, and potassium. You should only need two to three tablespoons of this fertilizer per plant per season.

Pruning: Individual hollyhock flowers can be removed when they fade and entire stalks can be cut back to the base after flowering. This will prevent seed heads from forming and reseeding. Although, if you'd like to have seeds set for next spring, leave the flowers and a few stalks until the seeds have dropped.
Harvesting Hollyhock Seeds:
At the end of the growing season (late summer or early fall), rather than picking the flowers on your hollyhocks, allow them to "go to seed" on the stalks.

When hollyhock flowers go to seed, they shrivel and turn brown. Eventually, the petals fall to the ground, leaving large, fuzzy, brown pods behind. These pods are seed pods, and they contain hollyhock seeds.

When they've dried to a medium brown on the stalk, it's time to harvest them.

To harvest hollyhock seeds, simply snap the hollyhock seed pods off the stalks with your fingers, dropping them into a brown paper bag. (If you want to sow them instead of saving them, autumn is also the ideal time for that. Simply scatter the seeds onto rich, fertile soil in a sunny spot in your garden, one that's appropriate for tall flowers like hollyhocks, and cover them lightly with soil.)

Keep the hollyhock seed pods in the paper bag until you're ready to begin the cleaning and drying process, which is the next step in saving hollyhock seeds.

Hollyhock seeds are large and flat. They often stick together in the pod and should be separated to facilitate drying.

Cleaning and Drying the Seeds:
To prepare harvested hollyhock seed for storage, crack open the seed pods, separating the seeds and discarding the pod.

Hollyhock seeds are rather large and flat. Inside the pod, they tend to stick together, and you'll probably have to separate them from each other using your fingernails. With tweezers (or your fingers—the pieces will be quite large), remove any debris or chaff.

Once you start handling the seeds, you'll realize that, despite the brown and shriveled appearance of the pods, the seeds aren't really dry. They still contain moisture and must be allowed to dry more before storage.

To remove the excess moisture, place the hollyhock seeds on paper towels, wax paper, or old window screens and allow them to air dry for about a week. Don't leave them much longer, as they'll begin to absorb the moisture instead of losing it, something you definitely don't want.

Culinary

Young leaves: raw or cooked. A mild flavor, but the texture leaves something to be desired. They have been used as a pot-herb, though they are not particularly palatable. They can also be chopped up finely and added to salads.

Inner portion of young stems: raw.

Flower petals and flower buds: raw. Added to salads. A nutritious starch is obtained from the root. A refreshing tea is made from the flower petals.

Medicinal

The flowers are demulcent, diuretic and emollient. They are useful in the treatment of chest complaints, and a decoction is used to improve blood circulation, for the treatment of constipation, dysmenorrhoea, hemorrhage etc. The flowers are harvested when they are open and are dried for later use. The shoots are used to ease a difficult labor. The root is astringent and demulcent. It is crushed and applied as a poultice to ulcers. Internally, it is used in the treatment of dysentery. The roots and the flowers are used in Tibetan medicine, where they are said to have a sweet, acrid taste and a neutral potency. They are used in the treatment of inflammations of the kidneys/womb, vaginal/seminal discharge, and the roots on their own are used to treat loss of appetite. The seed is demulcent, diuretic and febrifuge.

Companion Planting

Pair your Hollyhocks with bellflowers, daisies, delphiniums, foxglove, marigolds, phlox, rose mallow, sunflowers, 
yarrow, and zinnia. Some of these plants match the requirements of hollyhocks and some prefer dry soil and should be used to surround your hollyhocks to prevent competition.
A fiber obtained from the stems is used in papermaking. The fibers are about 1.9mm long. The stems are harvested in late summer, the leaves are removed and the stems are steamed until the fibers can be removed. The fibers are cooked with lye for 2 hours and then ball milled for 3 hours or pounded with mallets. The paper is light tan in color. The flowers are an alternative ingredient of "Quick Return" herbal compost activator. This is a dried and powdered mixture of several herbs that can be added to a compost heap in order to speed up bacterial activity and thus shorten the time needed to make the compost. The seed contains 12% of a drying oil. The red anthocyanin constituent of the flowers is used as a litmus. A brown dye is obtained from the petals.
