I bought a new home last year with my first yard and due to lack of knowledge used Scotts Lawn Care Services (which seems to not have done much of anything - still have bare spots and weeds). I have a two year old son and after reading about chemicals I decided to go Organic. This site is great, I am looking forward to beginning this year (I'm by Philadelphia, PA) without chemicals.
I have two questions, one has anyone heard of HappyLawn services? They claim to use fully organic products, however, there is a pre-emerigent crapgrass product and a weed herbicide - hard to believe that there are no chemicals in those.
Secondly, I have read that Corn Gluten is a good Weed Killer, has anyone used this? Please forgive me if this has been posted before.
The corn gluten stuff release a plant hormone that convinces weed seeds to not germinate. So you still have all the weeds that were already there. And it doesn't make the seeds never germinate, it just makes them wait a while. If you keep forking over money to the company, and taking the time to apply their stuff, you will continue to keep most of the weed seeds from germinating. And they might eventually rot and never germinate. But once you stop putting this stuff on your lawn, you might have a lot of weeds germinating all at once.
For me, I prefer to let the seeds germinate and then the seedling die from a lack of sun due to my tall, thick turf. Or let the seedlings dies from my infrequent watering.
