Black Spot on Roses Near Berries
 
I have some black spot breaking out on some of my roses. The roses have
strawberries growing around them.

What's my best course of action? Radical pruning? Some non-toxic spray?
Give up on using the strawberries for food, and use a toxic spray?

There are a variety of rose bushes. Some resistant. Some not. Most have
been there for a long time (before I owned the house). In past years
there was just a little black spot. Hardly anything at all, and I was
able to keep it under control with pruning. I'm not going to say I've
got a horrible outbreak this year, but it's more than in years before,
and I don't want it to get worse.

I'm outside of Portland, OR, and it's been a warm summer, but it's been
cooler and wetter for the last week or so. Summers are usually hot and
dry, but that may be a few more weeks off.

I'd like to be able to eat those strawberries that are around the roses,
and even if they weren't there, I don't really want to go with some
course of action that involves extensive chemical therapy. Nor am I some
organic-at-all-costs person either. I'm looking for a reasonable
solution, all things considered.

TIA

Black Spot on Roses Near Berries
 
Spray with Neem oil solution every weekend - it is organic and
non-toxic to us. The spots you got won't go away, but it will keep
more from showing up. Spray top and bottoms of leaves (have to lift
the strawberry vines) and the top of the soil.

Did I say spray every week? :) Works for me in Texas when the weather
is so wet the black spot gets out of control....like now!

Supposedly, you can spray every two weeks until threat of infestation
or growth is over (when it gets colder?) but I'm too lazy and only
start up when it gets bad.

Black Spot on Roses Near Berries
 
Remove the infected leaves and destroy and make sure any fallen leaves have
been cleaned up. Then start spraying your roses with aerated compost tea -
there should be Soil Soup kitchens in the nurseries in your area or you can
get a brewer and start making your own. Spray every 2-3 weeks during the
growing season (ideally this should have been started as the roses developed
new growth in early spring).

There is a growing body of evidence that aerated compost tea is able to help
plants ward off fungal problems. A number of nurseries in my area (Seattle),
including both of the ones I have worked at, treat all their roses with
compost tea on a regular basis and the results have been pretty impressive -
virtually NO blackspot or powdery mildew on any of the roses. The University
of Washington groundskeeping staff, the Port of Seattle and the staff that
maintains the rose garden at the Seattle Zoological Society all have adopted
the use of compost tea on their roses and other plants and the effects have
been remarkable.

Compost tea can be used safely with any edible plants, although I would
reccomend washing as usual before consumption.

Black Spot on Roses Near Berries
 
Well, you know my brugmansia collection. I have one which I bought from Logee's
about 9 years ago. It came with a virus. I suspect some type of mosaic. Not
only has it come through, it is magnificent. I slogged along for years. When I
started using the aerobic tea, it is now almost 6 feet tall...where it was only
three feet for almost 9 years. It also produced seed and is flowering almost
continuously now.

For anyone who is interested in aerobic tea, and hearing the founder of the
process, Dr. Elaine Ingram, please tune in next Sunday to KLBJ AM at 9AM CDST.
That's next Sunday. Dr. Ingram will be on the show with John Dromgoole. He
makes compost which is state of the art and has his own brand of certified
organic fertilizer, as well as being a fully organic garden center, John is just
a great person. Try to listen next Sunday morning. I do believe this is the

:::smacking my head::: Of course!

I went out and got a couple of gallons and a pressure sprayer today. (I
didn't have a sprayer because I never sprayed anything before.) I've
been meaning to do this for so long, but every time I went to the garden
center that has Soil Soup, there either was a line, or no one in sight
to serve it, and I ended up talking myself out of it. Either that, or I
had so many things on my to-do list, I didn't think I'd be able to make
use of it in 24 hours.

I'm looking forward to seeing the results. Thanks!

The area around and near the roses should be kept baron to provide as
much air circulation as possible. Pruning will help, and
removing/relocating the strawberries will help. If possible, increase
sunlight available (fungi generally do not like UV rays). Keep water
off the leaves. Prevention of black spot is a lot easier than
eradication, but there are several commercial spray products
available.
