Many garden fertilizers, pesticides and herbicides are designed to take the "back breaking" work out of gardening. Weedkillers in particular are manufactured to remove unwanted weeds by chemically destroying the root and removing the need to physically dig and lift it out of the ground.
Since no weedkillers on the market can be considered “organic”, organic gardening itself involves a lot more manual work. Having the right organic gardening tools makes gardening organically a lot easier and helps you to maintain a healthy garden without resorting to strong chemicals.
Soil forks are versatile organic gardening tools which can be used for loosening soil in preparation for new plants and turning soil and compost. It is also one of the more useful tools for uprooting weeds, removing them without the need for weedkiller.
