A shovel, spade or hand trowel are essentially all you need to plant. Plants are very forgiving as long as you don’t drop, kick or stomp on them when planting.
For balled and burlapped plants dig a generous hole when possible try to remove the burlap and/or wire basket and avoid excessive preparation of the planting hole. Be very careful not to drop or stomp on the rootball when planting.
Container plants benefit from having their roots loosened up since the roots are often “potbound.” Use a trowel or other hand tools to break up the roots. If the container is hard to remove, you can cut it off with pruning shears.
