About Saphyr Rouge Firethorn

Pyracantha coccinea 'Saphyr Rouge' · also called Saphyr Rouge Firethorn, Red Firethorn · flowering

A vigorous, scab-resistant and fireblight-resistant evergreen Pyracantha bearing masses of white hawthorn-like flowers in late spring followed by an exceptionally heavy crop of brilliant red berries in autumn and winter. 'Saphyr Rouge' is widely used for wall training, hedging, and wildlife cover. Pyracantha berries are mildly toxic to pets.

Plant type: flowering

Watch for — Training and pruning wounds: Prune after flowering to avoid removing flower buds; cut back only to a spur to retain the berry-bearing framework.

The reasons saphyr rouge firethorn isn't blooming

Almost every non-blooming saphyr rouge firethorn traces back to one of these, roughly in order of how common they are:

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

Feeding saphyr rouge firethorn 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 saphyr rouge firethorn to flower

  1. Maximise sun. Give saphyr rouge firethorn the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
  2. Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
  3. Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
  4. 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 saphyr rouge firethorn and get the feeding right with the saphyr rouge firethorn 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

Saphyr Rouge Firethorn 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.
