Does anyone know what these are on the leaf? Looks like eggs? But I can’t find any bugs crawling on the plant that would be responsible for it. Noticed lots of ants crawling over the plants though so something has attracted the ants
Looks like scale to me from the picture. The ants feed on the honey dew from the scale. You can then end up with sooty mould as well. You can control the scale with something like eco oil. Just make sure you don’t spray on a hot day.
Yes, agree completely with @LisasGarden. Scale. Check undersides of leaves as well and make sure to apply eco or white oil to both sides of all leaves.
