If they are still in the soil and not popped up yet, wet the soil, make sure you have good draining soil, put cling wrap over the top to keep the humidity in. If they have popped out, you shouldn't have to water for a few days or a week. Until they establish roots. But make sure you have good drainage. Then once the soil is dry a ways down (don't know the size of your pot, should start in solo cup first) just add water till a little comes out the bottom.
