@themichaelgriffiths: How to deal with black spot on your roses. The most serious disease for roses, with Black spots on your leaves which look unslightly, will turn yellow and likely fall off. The best thing you can do is to pick them off. Remove any affected leaves as they carry the black spot fungus. If you're doing this with a pair of secateurs remember to give them a good clean after to stop the spread - or you can pull in the opposite direction to the growth to easily remove them by hand. If you see leaves on the floor, pick them up. Anything that you pick up or pick off needs to be destroyed, don't put it in your compost heap. To reduce the likely hood or your roses getting black spot again do the following: Pruning at the right time, in an open bowl shape to an outward facing bud to reduce the chances of mould, mildew and black spot taking hold. Water deeply so the plant doesn't get stressed. Mulch to around 3inches, locking in water and suppressing weeds.
