You don't have to flush once a week, more like once a month. You want to let your soil dry out between waterings because when the soil dries out the roots go looking for water in turn building a more massive root system and keeping the soil wet all the time will do nothing but cause problems, root rot, bugs, fungus and so on. If you want to bush your plants out here is the best way, start buy drilling holes along the rims of your pots, then get some twist ties and gently tie one to the top of the plant and slightly start bending the top down so it is almost horizontal be careful not to snap the stem, then tie the other end to the pot so it remains in the same spot. and every time a new shoot grows, tie that one down too. Before you know it you will have a BUSH. I can usually take 30-40 cuttings per mother plant.
