If you want to grow hollyhock flowers, beautiful climbing plants that bloom in a wide array of colors, you can start by planting hollyhock seeds. They are wonderful to grow in your garden, or even against a wall, trellis or on a pergola.
When you have your hollyhock seeds and are ready to plant, make sure that you do so during the fall. This will give them a chance to establish their root systems under the ground during the winter. Or, you can choose to plant your hollyhocks during the spring, although this will mean you won't have any blooming until the following spring season.
For spring planting, select a location in your garden that sees at least a good six hours of directly sunlight, and make sure the spot is open for good ventilation. Spread your hollyhock seeds evenly on the surface of well tilled soil, and place no more than one quarter inch of extra soil on top of them. Water the area immediately, make sure to keep the soil moist, and never let the seeds go dry.
Regularly water the hollyhocks' bed, and do so at least two times per week. Keeping them continuously moist will ensure that their roots will establish themselves in the soil and promote germination. You can expect your hollyhocks to bloom come the next spring season.
For fall planting, repeat the same initial steps as with spring planting. You should also transplant any plants around the hollyhock bed, or thin them out so that they don't interfere with the new plantings.
Once the hollyhocks begin to show up in the ground, cut them back during the first frost. This is necessary because you don't want them to bloom just yet. Meanwhile, they will establish their roots underground. Water them and apply mulch around the flowerbed. Once spring comes, you should remove the mulch.
When spring arrives, water your hollyhocks biweekly, and make sure to deadhead the flowers so that you can get new seeds.
