- In cold areas, start the tubers indoors
about 6 weeks before you anticipate the last frost.
- Plant the tuber in potting soil, round side down, about 1″ below the surface.
- Water well and then keep the soil moist but not soggy. Keep in a warm, semi-shady area.
- When all danger of frost has passed, transplant outdoors being careful not to disturb the roots.
- In the garden, begonias need rich, porous, well drained soil and shelter from wind.
- Space 12″ apart in shade or partial shade. Keep moist and fertilize at
least once a month.
- In containers tubers can be spaced 4-5″ apart.
- Hardy in zones 9 and 10, all other zones the begonias should be dug and stored over the winter.
