Mutant -GenericAmerican - I recommend an automated drip watering system. They even sell kits for potted plants. Even if you think you'll be good at watering consistently, plants always seem to do better with an automated system.
I'm going to do one eventually just haven't had time and right now I water 2 times per day and am using Mulch to help keep the soil moist and seems to be going good so far
2 times a day is alot to keep up without forgetting and should become more frequent as the summer kicks in. Do you lift the pots to see how light they are to determine watering needs?
You don't need an expensive self watering system. Just a small amount of drip irrigation (say half in with spaghetti lines from it without drip emitters) from the home and garden store connected to a very cheap pump plugged into a ordinary and cheap 24 hr timer. Just fill a bucket or larger container with water and/or fertilizer.
The more cycles of wet/almost dry/wet in a day the faster the plants will grow.
