Roses- Brown leaves / dying
Have 4 roses that I bought spring of '12 (fragrant cloud, Elle, double delight, something else) kept them in 3 gal pots and planted them this spring. They did well all through last year and had nice roots when planted out this spring. Planted them in an area where I had just cut down a large pine. Root is still in ground. Dug nice hole with a lot of potting soil for roses. They get 5 hours of nice sun. Drenched with systemic treatment for black spot and mulched with pine needles. 1st month was fine, then leaves started loosing green. Treated with 2nd systemic 8 weeks later and no more new growth, leaves dropped off and what leaves didn't are brown and spotted and dry looking. Live in Z7 Va. This has been the best spring in years for rain and mild temps. Every thing else in garden in best ever. Have grown roses before with success.
Is this a problem with location (pine tree) or systemic treatment -Bayer?
