Top Tips For Growing Begonias


Begonias are drought-tolerant perennials, ideal for any garden. They come in a variety of forms and grow 15-30cm tall. Of the nine basic groupings of begonias, the most popular choices are rex, rhizomatous, shrub-like and cane-like.

Gardeners are often drawn to begonias for their shade tolerance, but make sure you check the plants' light requirements because not all Begonias are the same. Some will prefer dappled shade, while others will enjoy full sun.




  • Begonias like an acidic soil (pH 5.5-6.5) with humidity (around 60%) and good drainage. Use a good quality potting mix for indoor plants.
  • When planting, add a controlled-release fertiliser to the planting hole, then apply a general-purpose liquid fertiliser at 3-4 week intervals (fortnightly for pots).
  • Water begonias when the soil surface dries out. Ensure the pot is saturated, but avoid watering foliage. If it's an indoor plant, leave it in a well-lit spot to drain.
  • All begonias benefit from regular pruning. Some require tip-pruning in the early stages to encourage lateral growth. This can also be done at any time. Prune heavily if they become leggy.
