I planted a large rhododendron in my semi shade planter. Heavy humus, a drip system to keep it slightly moist. Added appropriate rhododendron food once a week as per instructions.
Most of the gorgeous blooms are dropping now.
My question is, do you prune the stems of the petals, those little spikes left after the petals fall?
Or more correct question maybe: What kind of care should I give now? As some of the woody branches are hanging slightly, can I control the shape of the shrub by supporting those branches?
Please and thank you.
