We live in Southern Cal so we would probably have to go the trash can route. Do the lawn clippings used in composting have to be fresh? We don't mow the lawns every week, every 2 weeks, so I imagine we would have to stock pile some clippings before getting started. Also, do you have to turn the mixture as it composts in the trash can? If so, how often does the compost have to be turned and how long could we expect the composting process to take to be able to use this in the planters?
If you are using the trash can it is a good idea to keep a bale of straw next to your compost to add to keep your compost from clumping up. How often do you need to turn it? The more often the better, at least once a week, but if you do not turn it at all the compost will still work, just take longer. With a trash can, it will take about three to six months, depending on how warm your area is. (Here in the tropics it takes about 3 months, probably will not be much longer in southern Cal.)
