How to Sow and Plant
+
Sow hollyhock seeds indoors from March to April in trays or pots, keeping the soil moist and warm. Transplant seedlings outdoors after 5 to 6 weeks, once they are strong enough and the risk of frost has passed. For direct sowing, plant seeds outdoors from mid-April to mid-May in well-prepared, sunny soil with good drainage. Space plants adequately to allow room for growth, as these can reach up to 140 cm tall. Ensure the site receives plenty of sunlight to support healthy development and vibrant flowering throughout summer.
Hollyhocks thrive in sunny spots with well-drained soil, where they can grow tall and vibrant. Regular watering supports steady growth, especially during dry spells, but avoid waterlogging. Deadheading spent blooms encourages prolonged flowering from midsummer to early autumn. Providing support, such as stakes, helps maintain upright stems against wind. These plants benefit from occasional feeding with a balanced fertilizer to boost bloom production. Their striking flowers attract pollinators, enhancing garden biodiversity while offering edible petals for creative uses. Enjoy their vertical charm in borders or as cut flowers to brighten indoor spaces.

These tall plants, reaching up to 140 cm, add stunning vertical color from July through September. Regular watering and occasional feeding will support vibrant blooms. Hollyhocks also make excellent cut flowers, perfect for fresh arrangements, and their edible blossoms can enhance culinary creations.
