Aphids are small insects no bigger than a quarter of an inch. They may be white or green or black. The little critters settle on leaves and stems of rose bushes to feed off the sap. They usually form colonies quickly so where you notice a few, there’ll be hundreds soon. Because they feed by piercing the leaves and sucking out the sap, they can transfer diseases to a plant that may spread through an entire rose garden. Damage from aphids is easy to spot: you’ll notice leaves that are misshapen or that begin to curl. Sometimes they may hide underneath the leaves, so check both sides if you suspect an aphid infestation of your roses.
Unfortunately, cutting your roses won’t get rid of the aphids. So, let’s discover how to get rid of aphids on roses.
