Hi! Thank you and welcome to our little rose garden community! Bi weekly fertilization, watering / soaking them in the evening during summer, and my natural climate.
I have also many Austinroses.I have never seen them so healthy and so beautiful then in your garden.even in David Austins rosegarden they are not that beautyful.
Wrong! Pacific Northwest Washington state also known as evergreen state because of highest number of rain days, thus high humidity, Although my spring is unusually dry this time, the whole fall last year to whole winter time is just crappy rainy. The gloomy weather , gets old you know. I control black spot by cleaning the rose bush base in the fall, so the fungus won’t over winterized and become systemic problem. I would also snip off foliage that gets BS like right away so it wouldn’t spread.
