Follow these simple step-by-step instructions when planting begonia tubers:

  • Place your begonia tuber on the soil surface with the convex side of the tuber underneath. This is where the roots will appear. The concave side facing upwards is where the growing shoots appear.
  • Push your begonia tuber firmly down into the top of the compost. The concave top of the tuber should still be visible.
  • Water in your tuber and keep in a frost-free place.

Tuberous begonias generally produce larger blooms than fibrous ‘wax begonias’ and they’re a popular choice for their bright colours and double flowers. Although usually treated like annuals, their tubers can be stored through winter for flowering the following year. Read our begonia masterclass for reviews of different varieties to try.

If you’re planting up a border, a begonia bumper back is a good way to enjoy a mixture of colours and flower forms. For hanging baskets, the trailing varieties in the begonia ‘Pendula’ mix make this collection ideal. And if you like to create contemporary hanging basket or window box displays, choose trailing begonias in a single colour to make a strong, eye-catching statement.
