Be conscious of summer temperature when watering cuttings set to root. All plants can be vulnerable to that first blast of hot water from a hose or watering can, but new cuttings are especially at risk. They exist in porous rooting media, usually in small spaces with few or no roots. The hot water sitting in just a few feet of garden hose can even burn their little green stems. Whether you are using Hormex Liquid Concentrate at the time or not, use the baby bottle test on the water that will irrigate the rooting bench – if a drop feels hot or cold to the inside of your wrist, wait a bit.
