About Pride of Rochester Deutzia

Deutzia scabra 'Pride of Rochester' · also called Pride of Rochester, Rough Deutzia · flowering

A tall, vigorous deciduous shrub producing arching branches laden with double white flowers tinged pink-purple on the reverse in early summer. 'Pride of Rochester' is one of the showiest deutzia cultivars, excellent as an informal hedge or specimen shrub. Considered pet-safe.

Plant type: flowering

Watch for — Poor flowering after hard pruning: Flowers on previous year's wood; cutting back in autumn or winter removes next summer's flower buds. Prune only immediately after flowering by removing the oldest, flowered stems to the base.

The reasons pride of rochester deutzia isn't blooming

Almost every non-blooming pride of rochester deutzia traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding pride of rochester deutzia a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get pride of rochester deutzia to flower

Maximise sun. Give pride of rochester deutzia the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here.
