Keeping your garden healthy requires a constant influx of nutrients. This happens naturally to some extent, either by weather, or by animals like birds, but nmany gardeners will supplement this with compost from garden centres, and through plant food. While this method certainly works, buying it can be a wasteful model. Creating your own compost is a relatively simple process, mainly relying upon the natural decomposition of waste. This would include such things as animal waste, human waste, food waste, and whatever trimmings that you take from plants, including your grass waste. By combining all of this into a pile, and then mixing them occasionally to insure that the various bacteria interact with all of the waste. One great way of determining how effectively the composting process is working is by placing a thermometer within it, and seeing if the temperature has risen. The ideal temperature for decomposition, and minimising the chance of seeds surviving the process, is by making sure the temperature remains between 130 and 150 degrees fahrenheit.
