Greetings, I am in Central Florida Zone 9b. Can I root cuttings of Blue Daze and Penta at this time? Temps are now in high 70's or low 80's. Thank you.
Blue Daze is readily propagated from stem cuttings taken in summer or root cuttings taken in spring to mid-summer. Fall and winter are times of less growth and the plant isn't sending out pro-growth hormones. Softwood cuttings (stem is green and bends easily) are the easiest to root. Semi-hardwood and hardwood cuttings are trickier. If you have a low lying stem, cover it with soil close to the tip. It will develop roots where it is buried. Pentas are most easily propagated using softwood cuttings in late spring or early summer. https://www.gardeningknowhow.com/ornamental/flowers/pentas/growing-penta-plants.htm
