Stock plants (Matthiola incana) are a very popular spring flowering annual that produce a magnificent display when planted out in garden beds. This is due to their columns of fragrant flowers that come in brilliant shades of white, pink, lavender, red and purple. They are ideal as cut flowers and will add presence to any dining table or garden alike.


How to grow stock in a garden

  1. Fill starter pots or trays with Yates Black Magic Seed Raising Mix. As stock seeds require light to germinate, press lightly into the mix and water well. You can also sow these seeds directly where they are to grow.
  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 cm before transplanting.
  5. When transplanting them into your prepared garden bed, ensure seedlings are well spaced – at least 30 cm apart. Water in well.
  6. Mulch with an organic mulch, such as bark chips, woodchip or pea straw.
  7. Feed regularly during the growing and flowering season with Yates Thrive Rose & Flower Granular Plant Food. TIP: For an added boost, apply Yates Thrive Roses & Flowers Liquid Plant Food.
