Watering around the base of the stem will only lock roots into one area. Roots don't chase dry medium, they chase moist medium.
Doing this will stunt root growth and will also create hydrophobic patches in the medium.
You want to water the pot properly, and as it dries, the roots chase the moist medium below.
Overwatering comes from too frequent an application rate. I water all my pots to runoff before seeds go in, and have never had an issue, and I don't have to water for at least a week or more afterwards. I just mist the top if it dries out too much, to keep it from going hydrophobic.
Most people can't fight the urge to water again in a few days though.
