Q.The Yellow Discolouration On My Rose Plant Leaves
Last autumn the roses were pruned and fed with horse manure and organic compost. The plants ( 25 roses plants in the ground) are now in seasons and have loads of buds but the leaves are yellowish green or have yellow blotches on them Is this a fungal infection or a nutrient deficiency? I live in the uk. Shropshire.
