Spade is another essential tool that comes with a long wooden handle and rectangular-shaped, metal shovel. A spade is a useful tool for digging holes, sand, turf or moving dirt from one area to other. Spades once purchased can last longer.
Loppers or pruning shears:
Loppers are used for cutting branches or pruning. They come with axe-like curved blades and long handles. Loppers are best choices to cut stems or branches of up to 2 inches in diameter and those that are too big to be cut from a secateurs. Hand pruner with small handle can also cut thick branches of trees or shrubs sometimes up to 2 inches. The only difference is that loppers come with long handles which allow you to cut stems that are little away from your reach.
Wheelbarrow is important while installing a garden on your own. You can use it for moving compost, soil and other ingredients in bulk. You can just put all your stuff in wheelbarrow and transfer to other location. A two-handed, single wheel tool can help you haul a proper amount of weight.
