A dibble (or dibber) can be a very nice tool to have. Essentially, it’s a handheld poking tool that creates a planting hole in the ground. The tool is generally cylindrical and comes to a point, somewhat like a stubby, sharpened pencil; larger ones may have a curved handle. End to end, the dibble may be up to 10 or 12 inches long. Fat ones are popular for bulb-planting or creating a hole for a larger seedling, while skinny ones are great for planting seeds or setting out smaller seedlings.
Why bother with dibbles? Because like any good tool, they make a project easier — your hand becomes much slower to tire. You can purchase one of many examples available from your local garden supplier, or you can make your own by sharpening a broken hoe, shovel, or broom handle. For small jobs, you can use a sharpened pencil or wooden dowel. Though a simple tool, a good dibble is often a two-part item. The top half, or handle, allows a comfortable grip and thus is usually wood or strong, durable plastic. If designed well, you should be able to grab the dibble almost like a pistol or screw gun, which reduces stress to your hand and wrist as you work. In any event, the bottom or digging or prodding half is best made out of strong, stiff metal, such as carbon steel.
Some dibbles have a hollow tip so that when the tool penetrates soil, the dibble captures displaced soil so you can set it aside. However, if you’re working in clay, this type of tool probably isn’t your best bet, because the soil tends to get stuck in the hollow and can be difficult to remove.
Owing to its smaller size and the scope of appropriate planting projects (namely, planting bulbs or seedlings), you shouldn’t be stooping or bending when using your dibble. Sit or squat on the ground, or kneel. This position also allows to you keep an eye on hole depth. Don’t get carried away, lazy, or tired and start plunking things into too-deep holes!
