Q.pyracantha with few flowers
Our pyracantha, or firethorn, seems to have very few flowers which always drop off before turning into berries. This has happened for about 4 years now. It grows against a fence and has sun for most of the day. A camellia growing next to it thrives. My wife is threatening to dig it up and burn it. Is there anything we can try to get it to perform better please?
Camellias thrive in acidic soil, whereas firethorn - not so much. So I think therein lies the difference - it's the soil. There are ways to modify soil to make it less acidic, as discussed in the following article:
