I planted my Mahonia 3 years ago but it hasn't flowered yet. It's growing really well and the leaves are a very healthy dark green. It's in full shade and clay soil. Any ideas how to get it to flower please?
Contrary to popular cultivation advice , I would transplant to an area of lightly dappled shade , or even full sunshine in a moist slightly acidic but fairly well drained soil .
I look after several of these , growing happily alongside large Rhododendrons and Camellias ; they are thriving in a moist peaty soil (never drying out) , and under the canopy of a large Sessile Oak (Quercus petraea) . I tend to keep them as 'standards' by pruning out shrubby side-growth .
Flowering is prolific each year , but seemingly getting earlier as they respond to the vagaries of our changing climate .
I agree about the light and moisture but mine flowers well on slightly alkaline clay.
Ok, thanks very much both for your help. Looks like a move is in order then :-)
