Compost would always be a good choice, but I no longer have a compost pile, and I'm not sure I want to get back into the work of having to maintain one. (The primary reason I gave up composting is because I no longer drive, and getting the right balance of greens and browns to create a good pile would be difficult. I have plenty of greens but almost no access to browns. [img]https://bestsmileys.com/clueless/4.gif[/img]) /quote]
Kisal - I know you are an experienced gardener, so I was sorry to hear that you gave up on composting, which I think is key to good organic gardens, maybe to good gardens period. If you've read my Keep It Simple posts, I have composted for years with very little but what my little city yard produces... weeds, spent flowers/plants, shredded remains of old tomato vines and woody plants, kitchen scraps, etc. I cheated a little at times by raking up fall leaves neighbors had piled in the street, because my yard doesn't produce a lot of leaves and last fall I cheated a little more by bringing home some bags of leaves that people had sitting out at the curb. Otherwise I just throw in whatever I have at the time I have it. (Always covering the kitchen scraps with weeds or leaves or whatever, so they don't smell or attract critters.) I turn the pile 3 times a year when I want to get to the finished compost at the bottom. I water it when I'm watering the garden. Otherwise I don't do anything.
The leaves are about the only brown I add, except the coffee filters and paper towels that are in the kitchen scraps, and occasionally some brown paper grocery bags, torn up. It's very little work & low maintenance and doesn't require additives from off the property. It doesn't heat up very much (gets a bit warm, but never hot) and earthworms, pill bugs, etc do a lot of the breaking down. But it produces lovely finished compost and the only weeds that ever sprout from my compost are volunteer tomatoes and squash.
Maybe you can reconsider and just find a way to compost that fits within your current lifestyle?
