I sure could use some sound advice on when and what to spray pyracantha to head off devastating fireblight.
Last season I almost lost my pyracantha hedges to this. It blackened all the many blossoms, which I quickly pulled off and destroyed, but of course this has meant that I have no berries on these plants.
The pyracantha's which are out the front of my property and are of the same family are perfectly healthy and showing berries.
I have climbing roses very close the hedges and last season these were wiped out with a mega dose of black spot, which I am wondering if this has infuenced the fireblight??
I am seriously thinking of removing the roses, and going for a fragrant climbing hyranga,
your thoughts and comments please!
