you do not have to go to the expense of purchasing organic anything to create an organic lawn.
start by what you have! do not use pesticides or chemicals on your lawn. water in the evening during hot months. twice a week. (some folks use rain water gathered by a drum connected to their gutters!) use your own mulch by placing egg shells, used paper products (cut or ripped up would be nice) banana peels coffee grinds....and if lucky- a bit of waste found in your yard by dogs or cats....scraps of vegetables-anything biodegradable will work. make sure you turn over your heap twice a month. no need for a container...you can simply pile it up in a corner of your yard.
after a good few months (some things take longer to break down). you can than process the dirt by putting a two cups of it in a container (a used milk jug), adding water and let sit with cap on for 24 hours. water your plants.....the dirt leftover can go right into the dirt in planters, or, better yet in your yard!
test it out-it works!
do you have a fish tank? if so, you can also use the water taken out during a water change to water your bushes and yard-or those special flowering plants. i find that is much easier than mulching, but i do both. the waste the fish make sure makes for healthy bushes or plants.
this is our second year in a rent house and while it took a year and a half to help the grass, it looks very green!
a hint? dont' bag your grass or your leaves.....gather the fall leaves and pile them high around the base of your trees. you will not have weeds around your tree all year! it also serves a protection during winter months.
leaving your grass cuttings on the lawn might look unsightly for a few days, but it 're-feeds' your lawn.....
organic? simple! just bear in mind if your neighbors use chemicals on their lawn, theres a possiblity it can run into your yard. but at least you've got more money in your pocket, less trash in the bin and green grass DOES look better on your side!
"sweetie" has a good idea as well! low ground covering plants actually look pretty cool-however, the association might not think so.....clover grows at different heights, but you can certainly cut down on the grass mowing (you do not have to use a gas powered one-they do make old fashioned push ones).
