  • For optimal growth, ‘Bertinii’ prefers fertile, well-drained soil with a neutral to acid pH. While partial shade is ideal, it can tolerate sun exposure except during extremely hot conditions.

  • The cultivation of ‘Bertinii’ is a delightfully straightforward endeavor, making it an easy addition to your garden. It resists the appetites of deer and rabbits and demands minimal care.
  • When planting, adhere to spacing guidelines of approximately 12 inches apart (30 cm) and position the tubers slightly below the soil line to avoid rotting, as these begonias are sensitive to planting depth. Many gardeners kickstart the growth of begonias indoors, giving them a head start of 4 to 6 weeks before transferring them outdoors, resulting in earlier blooms.
