Stachyurus praecox problems — and how to fix them
Stachyurus praecox (Stachyurus praecox) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Frost damage to early flowers
Blooms open in late winter and can be browned by hard frosts; site in a sheltered spot away from early-morning sun to protect the display.
Lime-induced chlorosis
Yellowing leaves with green veins on alkaline or chalky soil indicate poor iron uptake; improve soil with acidic organic matter or relocate to lime-free ground.
Drought stress
Wilting, leaf scorch and early leaf drop follow dry soil; keep consistently moist and mulch well, as the shrub resents prolonged dryness at the roots.
Loss of bloom from mistimed pruning
Flowers form on the prior season's growth, so winter or spring pruning removes the buds; prune only immediately after flowering finishes.
