I hate to use chemicals on my lawn, I keep things very organic. I'll tell you what I've done so far and if you could please give me additional advice I would be most greatful!!! I trimmed off any spotted leaves from the stem of the plant. I've checked the stem for any sign of disease and there does not appear to be any. I've cleaned the soil of any fallen leaves. This plant is new, planted rootstock this Spring. The area I planted in had never had roses before. This was the first addition to a rose garden I was just beginning, starting with a rose named Mary Rose which happens to be my recently deceased mom so I really want to keep the plant. PLEASE give me your best advice.

No, I'm not watering too much. If I'm guilty of anything it would be watering too little. The summer has been extremely dry and I know I should water them more. Could that be the problem???

This is what I use on my roses when they get black spot. purchase 2 32oz spray bottles.

Bottle one:
1Tbs Apple Cider Vinegar
1/4 tsp dish soap
1/4 tsp lite cooking oil (canola)
Water

Bottle two:
1Tbs Baking Soda
1/4 dish soap
1/4 cooking oil
Water

Spray your plants once a week with these solutions but not on the same day. Put a few days in between each solution. For example: spray one on Sundays and the other on Wednesdays. Make sure you spray top and bottoms of leaves, canes, and trunk. Also, make sure you spray early in the morning because it will cause sun burn. Clean up any debris around the rose. Throw the debris away (do not compost) and remulch. I live in OK and we had a monsoon for spring and early summer. Quite a few of my roses developed black spot and I started using these solutions as soon as I could. It did not take long for me to notice a halt to the black spot and now my roses look perfect. It even worked for my Hybrid Tea and they are hard to treat for black spot. Given that it is a David Austin, you shouldn't have any problem curing it.
Good Luck

Blackspot is a disease. Austins claim that their roses are resistant, so it is unusual for them to get it. A suphur spray should work. sulphur is as natural as anything else, although I am sure pure organic people would/may object. Growing garlic/other aliums beneath the roses my help. Reducing stress on the plant is important. correct watering and feeding will keep the plant in optimum health. Dig plenty of organic matter into the soil to help retain moisture. this will help reduce the risk of mildew aswell. Black spot tends to look bad, but except in unusual cases is not fatal. Hope this helps to reassure you. Mike

Yep, you have Black Spot(it extremely is the call of disease.)on your rose. it extremely is not bugs, even with the shown fact that that's a fungus disease on roses. you spot black spots on the leaves and the leaves will turn yellow and finally drops to floor. The moisture is inflicting this disease and that's difficult to administration this with fungicide spray. the final thank you to administration is to take each and every of the affected leaves off as quickly as you spot it, and rake away each and every of the fallen leaves decrease than rose bush, so the spores won't get to different timber. you may desire to attend to this bush in early next spring with fungicidal cleansing soap or some type. verify this rose is planted in sunny section and with a competent air flow.

baking soda dissolved in water and sprayed on the leaves is supposed to help black spot. Keep all affected leaves pruned off (destroy them) and don't allow them to lay on the dirt to infest it with the disease.

Organic is nice, but not practical for black spot. I use 3-in-1 spray.

good luck

You are probably watering them too much.
