Also the rule of thumb in soil is to feed water, water, water, water, then start again. Other wise you will get nutrient build up in the soil and it can kill them.
You're absolutely right Woody. Water too quickly and the liquid will just run out the sides of the pot instead of getting soaked up by the soil. Slowly adding water, then waiting for the water to get absorbed before adding any more, is the way to do it (especially in really dry dirt like that).
