I have numerous annuals in a shade bed in my front yard that I have decided to try and propagate from cuttings. In the spring I will harden them and replace this year’s (now dead) plants with the propagations. So far I have Coleus, Angel Wings and Creeping Jenny that I’m working with to return to the garden. Since I am new to this I am wondering if I should be adding plant food to the water? I have an aero garden that I have used for herbs and still have plant food so am wondering if it would be beneficial?
