Morning! I’ve noticed a lot of my cosmos have developed distorted thick leaf growth. There are a few blackfly ant farms in the patch, but not dreadful. Could this be the cause or something else?
I dug in a manure/soil improver a few weeks before planting, but haven’t mulched them or fed them, and I don’t use weed killers. Nothing else in the bed seems affected.
It does look like weedkiller. Could the roots only just now be growing into the manure layer? Or was it all mixed together? Could some have drifted from a neighbor? My parents are surrounded by fields.. and get weird growth on the plants near the edges once in a while if the farmer sprays during a windy day.
I could cut it off. They will bloom later, but on the bright side: it sort of extends your season and flower heights.
