Pigeon poop = natural plant killer/pre-emergent = in place fertilizers & minerals = good stuff.
Always looking for more free time I decided to put the
local birds to work for me.
Lately I have been putting out feeders on top of areas of vegetation that I no longer want. These could be grasses coming up from blown in seeds, or what is left from the pumpkin vines etc. After just a week or two (a light coating of poo barely noticeable) there will be
enough bird poo on the live plants to start killing them off and enough on the ground to keep most anything else from germinating/growing. I will then move the feeders somewhere else and let that ground sit for another couple of weeks. Sometimes I'll mulch over it, sometimes I'll run the
chickens over it. It doesn't really seem to matter so long as the bird poop is allowed to naturally break down and mix in a bit before planting there again. I have planted a bit to soon and burned up a few seedlings but when I timed it right I have also had plants "SURGE" into growth like I have never seen. I had a 6 inch butterfly bush become a 6 foot butterfly bush in just a few months this year and I saved myself some work in the process.
