By the mid-1960s many of the original wild collected rhododendron species were mature and in their prime. Since then Caerhays has discovered that the life span of a taller growing rhododendron species is a maximum of 60-80 years with many smaller growing species dying of old age in a much shorter timescale. Some species could readily be kept going into the next generations by propagating cuttings; a few others responded well to being cut back hard to encourage rejuvenation, but the majority of the larger growing and large leafed species cannot be propagated by cuttings and die if cut back.
