I have had several people email me and ask how they could compost if they were unable to have a compost pile.  The best way I have found is to bury the scrap organic materials directly in the planting beds.  This will encourage earthworms in that area, and in just a few days or weeks at the most, it will break down into good crumbly compost just like in a compost pile.  Do not bury too much in one place and keep it at least a foot away from you plants (this is to keep from disturbing the roots of the plants more than anything else).  Also remember do not use meat scraps, or bread in your compost.  If you do not want to dig in your garden beds for fear it will ruin some of your plants, just tuck the compost under the mulch around the plants and it will decompose there also.  If you have earthworms in your garden, you do not have to worry about smell, they will take care of it in just a matter of days.  I am constantly amazed at how much compost and organic material the soil can consume.  Especially here in our hot state of Texas.  It seems we can never get to much compost or organic material in the soil.  In fact it is just the opposite.  We seem to never be able to get enough into the soil.
