Soils

Use a good potting soil mix that has excellent drainage
Moisten the mix adding water until it is damp, but not soggy.
Place the soil in the pot you’re using to start the begonias, stopping 1/2 inch from the rim of the pot.
Plant the begonia tubers hollow side-up, spaced three inches apart.
Cover them with 1/2 inch of the soil mixture.

Sunlight

Place the trays or pots in a sunny windowsill and wait for them to sprout.
The tubers need bright light, but it shouldn’t be direct light or they will get overheated.
Keep the soil moist, but not soggy for the next month or so.
The tubers should sprout in two to four weeks.
Keep the temperature in the room at 30 C or higher.
A lower temperature will inhibit the tubers from sprouting.

Planting

Dig holes about two inches deep, spaced eight inches apart.
Place the begonias into the holes and lightly pat soil around the tubers.
The tubers should be covered with no more than an inch of soil, whether you plant them in the ground or in pots.

Water

The begonias should be watered whenever the soil feels dry.
