Pyracantha bush – espaliered

Question

It’s April, and the berries from last fall are still red and vibrant. Bush looks very healthy, but no sign of flowers. This doesn’t seem ‘normal.’

Answer 1

Your Firethorn will likely began flowering as it begins to warm and the sunlight intensifies.
As long as the shrub appears healthy there is no concern.
