It looks like chemical drift but...
(Cherokee Iowa )
this strange phenomena has been going on all spring and summer. Tomatoes, marigolds, petunias, potatoes, cosmos, impatiens etc. all have some degree of problems but my question is.. is there something in cat litter that can cause harm to plants? I had used empty litter buckets for planting and empty jugs for watering. Can that be a source of chemical drift?
