How to Tap a Maple Tree: Drill, Spout and Bucket, Step by Step
To tap a maple tree, pick a healthy maple at least 10 inches across, wait for a day above freezing in late winter, drill a 5/16-inch hole 1.5 to 2 inches deep into clean wood at a comfortable height, about 2 to 4 feet up, clear out the shavings, tap a clean spout in until it can’t be pulled out by hand, and hang a covered bucket. Collect the sap often, keep it cold, and pull the spouts when the buds start to swell. The steps below come from the University of Maine, Penn State, Minnesota and Utah State Extension guides.

Before you drill
The right tree
University of Maine Cooperative Extension says a tree should be at least 10 inches in diameter, measured at 4.5 feet above the ground, before you tap it, and that trees between 10 and 18 inches should get no more than one tap. Bigger trees can take a second. My taps per tree guide has the full chart and how to measure a trunk with a tape measure. Sugar maples have the sweetest sap, but they’re not the only option: trees you can tap for syrup compares red maple, silver maple, box elder, birch and walnut. Penn State Extension adds that unhealthy trees, or trees of low vigor, should not be tapped at all.
The right day
Sap runs on the thaw after a hard freeze. University of Minnesota Extension explains that sap flows when there’s a rapid warming trend in the morning following a night below freezing, so the amount changes from day to day. Penn State says warm days above 40°F and nights below 32°F normally start the flow. When to tap maple trees covers how to read the forecast, and what happens if you tap too early or too late.
Drill on a day that’s above freezing. Penn State says tap holes should not be drilled into frozen wood, and Maine says tapping on warm days, above freezing, lowers the risk of splitting the tree when you seat the spout.
The gear
- A drill (cordless is easiest) and a clean, sharp 5/16-inch bit. Minnesota says standard spouts take a 7/16-inch bit, but it prefers the newer, smaller spouts that take a 5/16-inch bit.
- One spout (also called a spile or tap) for each hole, sized to match your bit.
- A bucket with a cover, a sap bag, or food-grade tubing running to a container.
- A small hammer or mallet to seat the spout.
- Unscented household bleach for sanitizing the spouts and buckets.

Step by step: how to tap the tree
1. Choose the spot
Minnesota says the hole should be about 2 to 4 feet above the ground, in a spot that looks like sound wood. Maine just says a convenient height, and Utah State’s guide to producing maple syrup says about breast height, at a spot that’s comfortable to drill and collect from, won’t be buried by snow and won’t be out of reach once the snow melts. Anywhere in that range works. Look for clean, unblemished bark.
If the tree has been tapped before, stay away from the old holes. Maine says not to drill closer than 6 inches to the side of an old taphole, or closer than 2 feet directly above or below one. Penn State gives a smaller minimum, 2 inches to the side and 12 inches above or below, and warns that taps placed close to previous holes are likely not to produce sap. Giving the old holes more room costs you nothing.
2. Drill the hole
Maine and Penn State both call for a 5/16-inch bit and a hole 1.5 to 2 inches deep. Utah State suggests holding the bit next to your spout and marking the bit where the spout ends, so you can see the depth as you drill. Maine says to drill in one quick in-and-out motion with the bit turning the whole time, and not to redrill, which risks an oblong hole.
The guides split on the angle. Maine says to drill level and horizontal so the sap flows out on its own. Penn State and Minnesota suggest a slight upward angle so the sap runs down and out. Either works; the point is not to let the hole tip downward into the tree.
Watch the shavings as they come out. Penn State says cream-colored wood is what you want, and brown shavings mean rotten or unhealthy wood, so move the hole to another spot.
3. Clear the hole and sanitize the spout
Penn State says to clean all the shavings out of the hole, but not to blow into it, and not to put any sanitizing pellet or spray into it. Sanitize the spouts before you use them in a 20 to 1 solution of unscented household chlorine bleach, then rinse them thoroughly with hot water.
4. Seat the spout
Maine says to tap the spout into the fresh hole lightly, just until it’s tight and can’t be pulled out by hand, and not to drive it so hard that you split the tree. If sap leaks around a spout after tapping, check whether it’s loose. If it is, tap it in until it’s solid. If it isn’t, leave it alone. Penn State reminds you that the spout carries the weight of the bucket and the sap, so it has to be snug.
5. Hang the bucket
Hang the bucket or bag on the spout’s hook, or run tubing down to a covered, food-grade container at the base of the tree. Minnesota and Maine both say to cover open buckets so rain, snow and debris stay out of the sap.
Collecting the sap
Minnesota says a single taphole usually gives between 1 quart and 1 gallon of sap per flow, adding up to 10 to 12 gallons in a season. Maine’s advice: sap is like milk, and it will sour if you leave it sitting in the sun. Don’t let sap pile up in the buckets, especially in warm weather. Keep it in cold storage and boil it as soon as you can. Minnesota says that in cold conditions sap keeps one to two days with little loss in syrup quality, and Penn State suggests room to store about two gallons of sap per tap, enough for two days of collection. How long you can store maple sap covers keeping it cold without a refrigerator and the signs it has gone bad.
Then it’s time to boil. I boil the sap from my sugar maples on a cheap evaporator built inside my backyard fire ring, and how to make maple syrup at home walks through boiling, finishing, filtering and bottling. To see how much syrup your sap will make, use the maple sap to syrup calculator.
When the season ends
Penn State says usable sap may flow for four to six weeks, depending on the weather, and that you should stop collecting before the buds begin to swell, because that sap makes an off-flavored syrup called “buddy”. Utah State says to pull your spouts once the syrup starts to taste buddy and let the tree begin healing over the taphole.
Pull every spout. Penn State says not to leave spouts in the tree, and that tap holes do not need to be plugged, since a plug can interfere with the hole closing. It says tap holes usually close within three years, and that careful tapping doesn’t damage trees, with reports of trees tapped for 100 years. Next year, pick a fresh spot away from this year’s hole.
Plan the garden while you wait on sap
Sugaring season overlaps with garden planning. Plan My Garden is free to start: enter your zip code and it finds your frost dates, draw your beds, pick your crops, and it places each plant at square-foot spacing and builds a planting schedule (start indoors, transplant, direct sow) from those frost dates.
Quick questions
How deep do you drill to tap a maple tree?
1.5 to 2 inches, with a 5/16-inch bit, according to University of Maine and Penn State Extension. Mark the depth on the bit by holding it next to your spout, as Utah State suggests, and drill in one quick in-and-out pass.
How high up the trunk should you tap a maple tree?
Somewhere comfortable, in sound wood with clean bark: University of Minnesota Extension says about 2 to 4 feet above the ground, and Utah State says about breast height. Pick a height that won’t be buried by snow or end up out of reach when the snow melts.
How big does a maple tree have to be to tap?
At least 10 inches in diameter, measured about 4.5 feet up the trunk. University of Maine Extension says trees from 10 to 18 inches get one tap, and trees from 18 to 25 inches can take a second.
Do you plug the tap hole when you pull the spout?
No. Penn State Extension says tap holes do not need to be plugged, and plugging can interfere with the hole closing. Pull every spout at the end of the season; holes usually close within three years.
