Step-by-step instructions for hollowing out

  • Preparing the stump for hollowing out: In the preparation stage, wait for the wood to soften. Thus, starting the hollowing process a day or two after a rainstorm is advisable. As the wood gets softer by absorbing water, it becomes more pliable. 
  • Marking out the area to be hollowed out: Make the process simpler by marking the portion of the tree you want to hollow. Use a drill machine to punch holes across this section. Make sure the holes are a few inches apart in the section.
  • Removing the inner wood: Using tools like an ax, hammer, chisel or chainsaw, remove the wood from within. Begin the chipping from the edge of the holes by keeping the chisel at a 45-degree angle. Once the wood is removed, place it on a compost pile. You can use this as mulch later.  
  • Sanding and smoothing out the inside of the stump: Clean the hollowed area and even its jagged edge with coarse sandpaper. 
  • Adding drainage holes to the bottom of the stump if desired: This will be essential if you want to use the stump as a planter

  • Drill holes: Some people drill holes at the center of the stump, 8 inches deep and a few inches apart to make the process smoother. 
  • Chisel out: Use the chisel at a 45-degree angle from the flat stump surface. Using the hammer on top of the chisel, scope out chunks of wood from the center. It’s best to leave a few inches around the edge.

How to hollow out a tree stump with fire?

If you are not comfortable with manual methods and not confident about using a chainsaw, you work with fire. However, using fire to hollow a tree stump is not without challenges. Thus it’s mandatory to take proper precautions. 

This method is not ideal for those with wildfire-prone gardens. Additionally, this method is not ideal if the stump is too close to your home or garage. Finally, check with the local authorities about this use of fire before you use this method. 

How to hollow out a tree stump with fire

1. Prepare the area

Clear the place of any trash, leaves, and debris. Additionally, keep water hoses and fire extinguishers handy. 

2. Drill holes

It’s best to use a Power drill to make some holes in the stump right at the beginning. Otherwise, it might take longer. The holes must be at. 30-degree angle and around 8 inches deep. There should be some space between the holes. Remove the debris that forms around each hole. Avoid drilling to the edge of the stump. 

3. Add inflammable to the holes

To burn the stump well, add inflammable like potassium nitrate to the stump. Do not forget to wear protective gear like gloves and masks while handling such chemicals. If you use white crystalline salt, fill each hole with ½ inch of powder, right to the top.

Pour water into the holes and ensure the powder is dissolved. Once done, wash your hands well and store the remaining powder away in a safe place. 

4. Start the fire

Cover the wood stump with leaf litter, or dry wood scrape and light the fire. The fire will ignite the potassium and it will burn through the holes. It takes time for the stump to catch fire, so be patient.

Avoid using gas to light the fire as it may get out of control. Do not leave the fire alone. You don’t want to burn the stump completely so monitor the process and if the fire gets too big, use the extinguisher. 

5. Douse the fire

Once the fire has taken down most of the stump’s center pour water and sand over it to tame the flame. Cool down the stump completely and dry it before doing anything else. The drying process might take a week or two depending on the weather.
