Spiraea, also known as the May Bush (as this is when it flowers in the northern hemisphere) is a hardy shrub that’s covered in masses of beautiful white or pink flowers during spring. Growing to around 2m tall, spiraea looks fantastic as part of a mixed shrub garden and also when used as a hedge. It’s semi-deciduous in warmer areas and deciduous in cool zones.

How to grow spiraea in a garden

  1. Choose a sunny spot with well-drained soil. Enrich the soil with Yates Thrive Natural Blood & Bone with Seaweed.  If the soil is heavy or clay-based, to help improve the drainage add gypsum first and fork into the soil.
  2. Dig the planting hole twice as wide and to the same depth as the root-ball. Remove the shrub from the container, gently tease the roots and cut away any circled or tangled roots.
  3. Position in hole and backfill with soil, gently firming down. Water in well with Yates Thrive Natural Seaweed Tonic to help reduce transplant shock and promote root growth.
  4. Mulch around the base with organic mulch like bark chips, woodchip or pea straw, keeping it away from the trunk.
  5. Water deeply, once or twice a week, depending on weather conditions.
  6. Feed in autumn and spring with Yates Thrive Rose & Flower Granular Plant Food to promote strong root development, healthy leaf growth and lots of spring flowers. TIP: For an added boost, apply Yates Thrive Natural Fish & Seaweed+ Plant Food Concentrate.
