Planting perennial begonia
Begonia grandis is one of the few of its species to be hardy and to successfully cope with winter freezing. When planting your grandis begonia, ideally, you’d use flower plant soil mix or a mix of leaves and soil mix.
Growing Begonia grandis outdoors
Plant anytime from April onwards, directly in the ground, preferably in a partly shaded spot. In the ground or in a garden box, keep a buffer space of about 12 to 16 inches (30-40 cm) from one plant to the next.
- Begonia grandis tolerates sun if it isn’t too harsh. Morning sun or evening sun are fine.
- It’s a plant that love cool and moist soil.
- The richer the soil, the more abundant the blooming. Adding soil amendments upon planting, such as manure and seaweed, is very beneficial.
- Alternate your begonias with other bulbs that flower in summer (follow link for more tips).
Propagating Begonia grandis
Begonia grandis develops bulblets in Autumn. These appear at the point where its stems split. Bulblets help the plant spread and multiply naturally.
Pruning and caring for Begonia grandis
The care that begonia requires is quite easy, especially once it has settled in well. It only requires very little care, and will do just as well in a flower bed as it will in a pot, garden box or container. The only important thing is to remember to water your begonia grandis when they’re in pots, garden boxes and the like, as soon as the soil mix is dry in the surface: it needs constantly moist soil. Begonia grandis requires lots of water, even more so when grown out of the ground in containers like pots and garden boxes.
- Remove wilted flowers regularly, since this step helps boost new flower-bearing.
- Before winter, if you live in an area where it freezes hard, it helps to smother the base with a mulch made from dried leaves.
