Hi All

I have just read an article in the gardening section of Friday's paper in
regards to pruning roses, they state after pruning you should spray roses
& ground with either copper or sulfur spray but not lime sulfur spray.
Why is this when Yates put out a product Lime Sulfur spray that states to
do this, I am confused.
What is the difference in these sprays?
Yes I have been on google to find all this out & left confused.
Cheers

Don't prune until the first week in August or you'll burn the crap out of
new growth. Just to cold in Perth at the moment to contemplate this.

Lime sulphate would be calcium sulphate never used it.

I personally when pruning roses don't leave a single leaf on the bush that
means the leaves with black spot are gone. I make up a batch of 1/2 cup oil,
1/2 cup water, dessert spoon metho and a squeeze of dishwashing liquid.
Shake or blend then paint on the stems and buds straight away. This smothers
any scale or other nasties and does not burn the new growth. I find black
spot can also be lessened dramatically if you do a half prune in March.

This year in Perth has been excellent for roses as we haven't had a lot of
rain. The big storm cell that did all the hail damage some months back
dumped a bundle of nitrogen so a lot of things looked better for it. Shame
no real follow up rains.
