Also did you buy some potting compost too? Don 't use ordinary garden soil in pots. The begonias can grow up to 12" across so don't overcrowd them too much. I'd leave a good 4" between them
The petunias can spread to six or seven inches so that gives you an idea - 3" should be about right. The two should look fabulous together! (But in separate pots...)
And remember it is not warm enough yet to put them outside.

How big are your pots?
As these are grown as annuals it doesn't really matter if you cram them in, but do remember to feed and water them throughout the summer.
