I'm sorry; I should have been more clear.
Is the soil sandy? clay? nice loam? is there much organic matter--compost or composted plants/manures? have you by any chance had the county agricultural extension service perform a soil test so that you know whether the soil is acidic or basic (this is called the pH)?
If you have well-draining soil, keep on with the water. Don't drown the plant.
If you have poorly draining soil, don't water until the top inch of the soil is dry. Test it with your fingers for dryness.
