About Dogwood

Cornus sanguinea · also called Common Dogwood, Dogwood · flowering

Common Dogwood is a vigorous, deciduous native shrub of chalky and calcareous soils across England, Europe, and western Asia, widely grown for its vivid crimson-to-purple winter stems, clusters of white flowers in June, and glossy black berries. It is extremely hardy, tolerates shade and exposed sites, and is the most important hedgerow and wildlife-garden shrub for hard-pruning back annually in late winter to maximise coloured stem display. Berries and plant material are mildly toxic to cats and dogs.

Plant type: flowering

The reasons dogwood isn't blooming

Almost every non-blooming dogwood 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 dogwood 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 dogwood to flower

Maximise sun. Give dogwood 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. Dial in the spot with the light guide for dogwood and get the feeding right with the dogwood fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Dogwood flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.

For everything else this plant needs day to day, see the full dogwood care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

Dogwood blooming — frequently asked questions

Why won't my dogwood flower?

Dogwood blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make dogwood bloom?

Give dogwood the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
