Hollyhocks (Alcea rosea), with their predominant stems of brightly coloured, double blooms, stand tall amongst the rest of the garden from spring to summer. They can grow up to a whopping 2 metres in height and are ideal as an annual decorative backdrop along sunny walls and fences.


How to grow hollyhock in a garden

  1. Fill starter pots or trays with Yates Black Magic Seed Raising Mix. Sow Hollyhock Double Elegance or Hollyhock Pink Powderpuff seeds, cover, firm down and water well.
  2. Water gently and keep moist through germination period.
  3. While the seedlings are growing, choose a spot in the garden that receives full sun and prepare the planting area well by digging in Yates Thrive Natural Blood & Bone with Seaweed.
  4. Allow the seedlings to grow to at least 5-7 cm before transplanting.
  5. When transplanting them into your prepared garden bed, ensure seedlings are well spaced – at least 30-40cm apart. Water in well.
  6. Mulch with an organic mulch, such as bark chips, woodchip or pea straw.
  7. Feed during the growing and flowering season Yates Thrive Rose & Flower Granular Plant Food. TIP: For an added boost, apply Yates Thrive Natural Fish & Seaweed+ Plant Food Concentrate.
