HOW TO DEAL WITH BLACK SPOT LEAF DISEASE – Black Spot Leaf Disease is very easy to see when you examine a plant. You will literally see the leaves covered in black spots and left untreated it will spread rapidly on the host plant and then to other plants. In this guide we provide you with easy to follow steps that will help you combat and prevent further problems caused by black spot leaf disease.
Spotting black spot leaf disease is easy… Just look at the top of the plant’s leaves, if you see black spots then you know this fungus has infected your plant. The black spots range in size, from pin heads to large blotches. Like any plant disease, Black Spot starts off small, hence the pin head spots, and then grow as the disease takes hold. Roses are particularly prone to Black Spot so make sure you check over your plants as you work about your garden. If you do notice any Black Spot then take action immediately.
Put on some rubber gloves and take a pair of Secateurs or scissors and prune the plant back until there are no leaves with black spot left. Be vigilant and make sure you check over the entire plant. If you do leave any part of the plant with any infected leaves then the black spot will spread again.
DO NOT leave cuttings lying around and DO NOT put them on your compost heap – BURN THEM otherwise you’ll end up spreading the problem to your other plants.
Buy a fungicide from your local Garden Nursery and follow the manufacturer’s instructions for use.
Check other plants in your garden, especially those closest to the one that was infected. Black spot can spread very easily which is why you much collect all the cuttings and burn them.
