  6. Mulch with an organic mulch, such as bark chips, sugar cane or pea straw.
  7. Feed every 1 to 2 weeks with  Yates Thrive Roses and Flowers Liquid Plant Food.

How to grow from a tubers

  1. Once the weather warms up stored tubers will start to form eyes or shoots. Once these start to form the tubers are ready to plant out.
  2. Choose a sunny spot in the garden and prepare the planting area well by digging in some compost & Yates Dynamic Lifter Soil Improver & Plant Fertiliser.
  3. Dig a hole that is double the size of the tuber and water well prior to planting ensuring that you have left at least 30cm spacings between each tuber.
  4. Plant them whole with the growing eyes or shoots facing up. When planting make sure that the root end of the tuber is covered by at least 10 cm of soil.
  5. Once planted, do not water the tubers right away as this could encourage rot. It is best to wait until the sprouts have appeared above the soil to water.
  6. About 2 weeks after sprouts appear, feed them with Yates Thrive Flower & Fruit Liquid Plant Food.

Growing tips

  • Remove spent flowers to encourage further blooms during summer and autum

  • Taller varieties of Dahlias will require staking to maintain healthy growth and lovely blooms. For these varieties it is best to stake the plants upon planting the tubers to avoid any root disturbances later on.

  • To encourage bigger blooms, leave two or three flower buds on the plant, disbud any additional or smaller buds that may form.

  • Allow the plants to die down in late autumn and winter. Once the plants have died down, you can cut the plant down to ground level.

  • In cooler areas or in poorly drained soils, it is best to dig up the tubers and store for the winter. When removing, take care not to damage the crowns and store either in a corner of the garden shed or in boxes filled wbers attached.

  • Dahlias can be propagated from soft tuber cuttings in spring. Once the shoots have formed carefully cut between the shoots leaving some stem tissue surrounding the shoot and one or two tubers attached.
  • When picking flowers for indoor decoration, this is best done in the cool or the evening.
