I would say that your roses have a bad case of black spot. Clean up any leaves and bin or burn them, do not put them on your compost heap.

Black spot spores live in the soil over winter.

Next spring start to spray the soil and roses with a fungicide before any new growth appears and continue with a spraying regime throughout the season.

Answer 4

If the leaves are not being eaten by deer, bugs, etc, they must be losing their leaves because they are being stressed by something.

Roses can lose their leaves from lack of water or from too much water.

A mature, average-sized rose bush can lose up to 5 gallons a day when it gets really hot or exceptionally dry!

"You can cause leaf dropping and blackspot,(if you live in a high humidity area), from watering the branches of your rose bushes.

They should always be watered at the base of the plant.

Over watering will cause the leaves to turn yellow and drop off, also.

Too much water will cause root rot and can cause your rose bushes to die.

Water deeply, two times per week."

Check to make sure your rose bushes have good drainage & make sure they have plenty of air circulating around them, so leaves can dry after it rains.  Powdery mildew can also result in roses losing their leaves:

Make sure your roses aren't either starving or overfertilized.

Roses will thrive better if you use NPK (Nitrogen, Phosphorous, Potassium) ratios of about 1:2:1... more Phosphorous than nitrogen or potassium. Check the pH of the soil - around 6.5. --is best to insure the ability of your roses to use certain minerals and nutrients in an efficient manner.

"Most roses will benefit from regular application of fertilizers in small amounts. Sometimes you can even feed with liquid fertilizers as often as every two weeks. The more your roses put out new growth and bloom, the more fertilizers they will need.... If it is in desperate need of nutrients, it will actually lose its leaves and a few canes will die...(but remember)... Don't overfeed! This can kill or damage your roses. If you are applying chemical fertilizers ALWAYS follow the dilution amounts on the label"

Stop applying fertilizer  six weeks before the killing frost.

Did you recently transplant your rose bushes?  They can lose their leaves as their roots get established. This just happened to my rose bush. They needed to be watered a lot to get established...but the bush has all new leaves now!  I know that this wasn't the best time for transplanting it, but I had to move it now or lose it...so I took the chance.

Good luck!!!  Hope this helps.

Answer 5

Are the leaves on the ground?  If so, you should see evidence of bugs.  If your leaves are completely gone from the branches - animals could be eating them.
