Pyracantha Plants
Q.

pyracantha bushes not having berries

Zone Northwest PA. (zone 4 or 5, depending who you ask) | Janet k added on September 10, 2015 | Answered

A row of firethorn bushes is planted along the northeast side of our garage. There are 7 or 8 bushes crammed into this space and they all seem to be growing into one another. Two bushes on one end of this row have orange berries on them; the rest just leaves. Would it be possible to remove every other bush to get some air in there without damaging root systems of the ones I want to keep? Would the thinning procedure encourage remaining bushes to bear fruit? Is there something else I can do to change these bushes from an eyesore to an asset?

Pruning and some soil corrections may be all you need.
Pyracantha are often planted and grown as a hedge so if this is the reason for you plantings you may not want the look of spaces in-between the bushes.

You likely would do some damage to plants in attempts to remove some but if you do attempt this wait until the they are dormant.

I would start with a soil test. Your lack of berries is likely from to much Nitrogen in the soil.
You can adjust this with an application of Phosphorous rich fertilizer like Bone Meal.
