Summer Carnival Holly Hock Seeds

Planting: To achieve early spring growth, sow hollyhock seeds directly in the soil in August or September. Alternatively, you can plant the seeds in spring after the last frost. This plant thrives in full sunlight and nutrient-rich soil, preferably in a sheltered area. Plant the hollyhock seeds no more than 0.6 centimeters deep and ensure that the soil remains moist until the seeds germinate, which usually takes about 14 to 21 days. Space the seedlings 50 to 60 centimeters apart in rows that are 90 centimeters apart. If necessary, you can transplant the thinned seedlings. If you prefer to start the seeds indoors, plant them slightly below the soil surface and maintain a moist soil temperature of approximately 21 degrees Celsius until germination. Once the last severe frost has passed or the plants have grown sufficiently, you can safely transplant them.


Growing: When the hollyhocks begin to bloom, it is important to prevent the soil from drying out as these plants are not tolerant of dry conditions. Water the plants carefully, avoiding wetting the foliage to prevent the onset of rust and other diseases. If you notice any rust-infected leaves, remove them immediately. Pay close attention to young plants, particularly for slugs and snails. While some first-year plants may produce blooms, full flowering typically occurs in the second year of growth. Pruning the tips of the stalks for several weeks will promote fuller and shorter growth. Hollyhocks tend to self-sow easily, making them practically perennial unless you remove spent blossoms to prevent seed development. After the first autumn frost, cut the hollyhock stalks down to ground level and cover them with a layer of mulch for protection. Remove the mulch in spring. Hollyhocks also thrive as container plants and attract hummingbirds, butterflies, and bees.

To harvest Summer Carnival Hollyhock Seeds, wait until the flowers have wilted and dried on the plant. Then, carefully collect the seed pods or capsules from the stems. These pods will contain the hollyhock seeds. Place the collected seed pods in a dry and well-ventilated area to allow them to fully dry out. Once dried, gently open the seed pods and collect the seeds inside. Store the harvested seeds in a cool, dry place in an airtight container until you are ready to plant them in your garden or share them with others.

To save Summer Carnival Hollyhock Seeds, allow the flower heads to mature and dry on the plant. Once the petals have withered and fallen off, the seed pods will begin to form. Wait until the seed pods turn brown and feel dry to the touch before harvesting them. Carefully remove the seed pods from the plant and place them in a paper bag or container to finish drying indoors for a few weeks. Once completely dry, gently crush the seed pods to release the hollyhock seeds. Remove any remaining debris and store the seeds in a cool, dry place in an airtight container until ready for planting.
