My Mock Orange shrub is 3 years old and never had a bud or flower - I have hardly pruned it - why is this?
You say you have hardly pruned it, but any pruning at the wrong time of year could remove flower buds. Mock orange (Philadelphus) is pruned immediately after flowering. I'd leave yours well alone until it does flower. Feeding now with sulphate of potash will help 'bump' it into flowering.
