As we thrive for a soul-to-soul connection, the plants indeed look for a root-to-soil connection. A good bulb auger is what you need for matchmaking! Bulbs require a bit thicker hole than seeds for obvious reasons and a bit deeper too. Hence these drills like automation are the only way to go if it’s not a one time deal.

Even if you’re willing to get your hands dirty for spooning the ground, these bulb augers have their demand. Well, you can’t spoon through those roots now, can you? These can spin through them like knives through butter. Life becomes easier now. Drill, through the seed in, fill up the hole, that’s all.

Garden becomes half the work once you don’t have to plant those bulbs. So, bulb augers are a shortcut to that gruesome task. Press of a switch, that’ll give you that perfect hole. So, what makes the best bulb auger, let’s find out.


Bulb Auger buying guide

In this section of the article, we are going to talk about every single aspect of the bulb auger you should know before buying it. To make you choose wisely, it is very important to have a clear concept regarding this product.


Hex Drive

The part of the drill bit that gets attached to the drill machine is the hex drive. So, the hex drive is a major safety concern as it can get detached while drilling and can cause injuries. Non-slip hex drives are likely to have great grips while using.


Indeed, the auger bit is a good replacement for the shovel used for landscaping. Here, the bulkiness varies from 0.35 lbs to 1.3 lbs. But if it is way too bulky, it will cause serious discomfort. So, auger bits around half a pound are preferred in this regard.


The length of the auger bit you need depends on the size of the plants or the plant roots you are digging the soil for. The market provides you from 7 inches to 16.5 inches for regular use.

If you are planting a large size plant or a plant with a deep root, you should consider buying a comparatively longer auger bit. But they are usually slender and the spiral portion doesn’t cover most of the length. Handling them requires a bit of skill and hence are recommended for regular gardeners.


Welds between the slender body and the spiral portion of the auger mustn’t have many metal globules. The smoother the weld is the more is the durability. But sometimes the paint coats hide them.


Heavy-duty steel is the trend in the market and is the recommendation too. Many times the priority shift should be adopted for painted finishes. But this matters less as almost all good augers come with black coating and secondly, the auger comes in contact with the earth in a continuum.

For which drill?

Usual auger bits require an 18V drill. But in most cases, you need to get into places where an electric outlet is not close at hand. Cordless drills have no other alternative for you if you are one among them. A 14V auger drill is a suggestion for cordless operation.

Don’t forget to check whether the bulb auger you are intending to purchase is compatible with ⅜ inch chucks. Topmost augers have this feature and it allows you to cover most of the applications that a bulb auger should indulge in.
