Looks are deceiving...

Despite how lovely and pretty this rose looks, I'm really struggling trying to keep them healthy and happy (actually a bit like me) this roses had 2 either water spouts or suckers so I've cut them off, I've noticed a couple of leaves with black spot plus some yellow leaves, my red rose bush has wilted leaves which is because I over watered it, then my miniature rose bush now has mould on it... So very late this afternoon when the temperature drops I'm going to spray the 3 of them and see what happens...
