This should be done after the soil has been broken to the full working depth . The compost should be worked in to a depth of six to seven inches . This may be done by working the length of the garden and then by making separate passes across its width . The addition of decayed organic matter will substantially increase the fertility of your garden . For proper decaying action , fertilizer should be applied and worked in with the mulch materials . Breaking up leaves and straw and mixing it with several inches of soil causes the soil to hold moisture longer and allows proper aeration of the plant Figure 9 root system . This also retards the growth of weeds . SECTION 5 : MAKING ADJUSTMENTS WARNING : Disconnect the spark plug wire and ground it against the engine before performing any adjustments .
