Gleni said:I noticed the mention of Johnson grass, which was new for me. It is a sorghum? It looks like what I have growing by my feeder. Should I zap it?
Gleni I can't be sure without some web searches. What we refer to as "Johnson Grass" is a zombie of plants. It is literally the living dead, cutting a root creates two new. It is Sorghum halepense or similar. We have many similar varieties all combined as "devil grass". I'd need to consult my books but they're all focused on N. American grasses and weeds. I'd nuke it but with the feeders I'm not sure what would be safe?
You want to stick to feeding friends, not killing them.
This is a risk of using bird feeders anywhere on earth. Weed seed is of value for the critters. Containment would be best left to more experienced people but you don't want to open too much window of opportunity with weed grasses. If I were to kill off my entire turf area to kill similar grasses would be an exercise in futility as my turf is surrounded by farmland where they've thrived forever. At least hundreds of years if not thousands. You can manage enough to enjoy your garden but these old grasses exist for good reason. They provide, not what we desire but they do provide.
When I cut it in my garden I'm insured new growth, X2 or 3. Dandelions and thistles can be dug or sprayed. Bad grasses are something else entirely. Short opinion on bad grasses near anything valued would be to try to kill it and kill it good. Unless you enjoy coarse grasses in your salad. Weedy grass roots win. Grasses grow almost everywhere.
Hope you can consult someone nearby? All my books are US based but worth a look.
