Questions

I planted patio roses in my garden last year. There are lots of rose-buds on the top ready to open now. However the bottom branches are discoloured and not looking too healthy. I water regularly. Can you over-water, by chance?Is it possible that these small patio roses don't do too well when planted in the garden?

My roses are prone to blackspot. I have heard that spraying Jeyes Fluid into the soil helps to prevent this problem. Is this true and, if so, when would be the best time and method of doing this?

I have nearly a dozen different rose bushes in my back garden this year i noticed a green caterpillar on the leaves.

I have Rosa Albertine (15 yrs old) growing on a metal fence for last 2 yrs and it is not thriving. It was previously on a wooden fence which had to be replaced. The rose was not moved and is fed and given a good mulch of well rotted manure every year. Does it dislike it's metal support which is painted with Hammerite paint?

I live in the country. A deer appeared in our garden and ate all of the leaves off of 3 rose bushes and an arbutus plant. Apart from the obvious damage of all of the leaves being gone, Will these bushes recover? Do I need to prune or treat them? someone told me that the deer saliva might damage plant and I should prune them back.

My sister lives near me and showed me her rose bushes today - they are all very weak ie leaves pale and some not opening. There are about 20 like this. It is not black spot or rust. Any ideas? I seem to have read recently about a new virus. Is there one?
