How to Plant a 15 Gallon Tree

This blog post will show how to plant a 15-gallon tree. The first step is to dig the hole. It should be twice as wide and deep as the root ball of the tree you are planting. Next, fill in the dirt around the edges of the hole but leave it loose at one end for now (this will be covered shortly). Next, position your 15-gallon tree to center over the spot with its trunk facing down into it.

Lastly, backfill dirt around where you dug out soil from, making sure not to cover any roots or branches if possible. We provide all the information you need about how to plant and care for your newly planted tree so that it will grow strong and healthy. Read on if you want an easy way to make your home feel more like home!

Things You’ll Need:

  • A 15 Gallon Container

  • A Wire Mesh Crab Pot Liner
  • Scissors for cutting crab pot liner
  • An Ice Pick or Augur Drill Bit

Instructions: How to Plant a 15 Gallon Tree

Step 1: Know your soil’s pH.

Knowing your soil’s pH will allow you to choose to add/remove certain minerals that affect the soil’s acidity/basicity. This is important for growing a plant because if the right conditions aren’t met, the nutrient lock may occur, affecting the soil’s nutrients. The following is a list of different soil pH levels and what you can do to alter them:

  • 5.5 and below: Add limestone to increase alkalinity, sulfur to lower it.
  • 6.0: No real need to adjust.
  • Between 7 and 8: Add crushed shells or gravels instead of limestone if the soil is in a pot.

Step 2: Choose a standard tree.

There are many options to choose from throughout the world, so experiment and find out what works best for you. Some popular choices are oak, maple, birch, spruce, sycamore, cedar. However, don’t limit yourself – there are many other options out there for you to explore. So get out there and find the wood that works best for you.

Step 3: Construct a scaffold.

A scaffold must be constructed so that the tree’s trunk is elevated off the ground by 2 inches. A metal or plastic vinyl tube is commonly used for this purpose. Use your cordless drill, with the appropriate drill bit, to boreholes in the box. Insert a metal rod into each hole and wrap it tightly with a hammer. The rod should be about 2 feet long.

Step 4: Transplant your seedling into the scaffold.

Take care not to damage or break any branches on the seedling. If they are broken, new ones will appear. Next, place the seedling into the scaffold by carefully guiding it through the top.

Step 5: Water your tree with distilled water or rainwater

Your tree requires high-quality water to grow healthy and strong. Tap water contains chlorine that damages plant life. Distilled or rainwater does not contain chlorine. If you cannot get your hands on distilled or rainwater, place tap water into a clean bowl and let it sit for 24 hours to allow the chlorine to evaporate.

Step 6: Be patient

Your tree will take 5-7 years to grow up. Make sure you have enough space for it before planting because it will never be moved once it is planted. In the meantime, you can have fun by decorating your tree with a hammock or bench.

Some Tips and Tricks:

1. Watering: Water your tree every day for the first three weeks. After that, water it once every other day. Soaking the whole container in water for thirty minutes will help prevent problems (such as root rot). If you live in a hot climate, you may need to water twice daily because of high temperatures and low humidity.

2. Temperature: The tree must be kept at 70 degrees Fahrenheit during the first three weeks. You can encourage root development by keeping it slightly more relaxed (65-68 degrees). After that, keep it above 60 degrees.

3. Fertilizing: After planting your taro plant, fertilize once a week for two weeks. After that, fertilize every other week until the taro is ready for harvest. Use a water-soluble fertilizer or compost teas to fertilize your plant occasionally.

One of the Top 10 Most Common Tree Planting Mistakes

1. Not removing the tin foil wrapper from the bottom of the trunk when transplanting

2. Failure to remove rocks, stumps, or roots when digging an area large enough for your tree

3. Digging a hole that is too small for your tree’s root system

4. Not fertilize your young tree every two weeks for the first six months and once a month afterward if you live in a very cold or dry climate. Potted trees should also be fertilized upon replanting into the ground

Common Tree Planting Mistakes

5. Planting your tree too deep.

6. Planting in a position that faces full sun when you know it will eventually need full shade (deciduous) and vice versa (evergreen).

7. Failure to water enough after planting

8. Watering on a set schedule without checking for adequate moisture levels

9. Choosing a site that is too windy or having a location in an area where the roots will be constantly moist.

10. Not mulching at least 3″ around your tree’s base.


Planting a tree can be an easy and enjoyable task. Choose the right type of tree for your yard, research how to plant a 15-gallon tree properly, find good soil, water regularly, and enjoy! Trees are great additions to any home or property because they help clean air by providing shade that cools down hot surfaces in the summer months.

It is essential to take care of trees after planting them because otherwise, you may end up with broken branches or, worse yet, have the whole thing die prematurely.
