But then I decided that though the fertilizer made the lawn look green, it also meant I had to mow it more often.
OTOH, IF I NEVER APPLY FERTILIZER, HOW LONG WILL THE GRASS GROW? 10 YEARS? 20? 50? 100? Surely the earth will run out of nutrients eventually????
2) I switched to spray-with-garden-hose weed-killer once a year in the spring, and indeed, this year, even though I didn't spray, I had only 3 dandelions. (Though I still have patches of other weeds) BUT, DOES WEED B GONE ETC. DAMAGE TREES AND BUSHES? I know once I got some on the end of a branch of a tulip tree, and it killed 6 or 7 leaves and the 15" of branch they were on. I don't think they ever grew back but the rest of the tree has been doing well, grows a foot or more higher every year. BUT WHAT ABOUT WHEN I SPRAY THE STUFF ON THE GROUND BENEATH THE TREE?TIA
