Tree That Looks Like A Mushroom – A Gardener’S Pruning & Care Guide

ByRimon Chowdhury Updated on

Have you ever strolled through a beautifully designed garden and stopped in your tracks, captivated by a striking, sculptural tree? One with a clean, single trunk and a perfectly rounded canopy, almost like a storybook mushroom?

You’re not alone in admiring that unique shape! It’s a classic look that adds structure, whimsy, and a touch of formal elegance to any landscape. Many gardeners think achieving this look requires years of complicated training or a professional landscaper on call.

I promise you, it’s more achievable than you think. With the right plant choice and a little bit of know-how, you can absolutely cultivate that gorgeous silhouette yourself. This guide is here to be your friendly companion on that journey.

We’ll explore the best species for the job, walk through a complete tree that looks like a mushroom care guide, and master the pruning techniques that turn a simple tree into a living work of art. Let’s get started!

What Exactly is a “Tree That Looks Like a Mushroom?”

First things first, let’s clear up a common point of confusion. There isn’t a single species officially named the “mushroom tree.” Instead, this charming description refers to a specific shape or pruning style, often called a standard or a topiary.

This look is defined by two key features:

  • A Clear Trunk: The lower portion of the tree is kept free of branches, forming the “stem” of the mushroom.
  • A Rounded Canopy: The upper foliage is carefully pruned into a dense, dome-like or spherical shape, creating the “cap.”

Some trees naturally grow into a shape that lends itself to this style, while others can be trained with a bit of patient pruning. It’s all about selecting the right candidate and guiding its growth.

Top Tree Choices for the Perfect Mushroom Shape

Choosing the right tree is the most important step. You want a plant that responds well to pruning and has a growth habit that works with, not against, your goal. Here are my top recommendations, from easy-care options to those that require a bit more sculpting.

The Globe Catalpa (Catalpa bignonioides ‘Nana’): The Classic Lollipop

If you want a tree that does most of the work for you, the Globe Catalpa is your star player. This is a dwarf, non-flowering variety that is typically grafted onto a standard catalpa rootstock. This grafting process is what creates the distinct “ball-on-a-stick” look right from the nursery.

Its huge, heart-shaped leaves create a dense, lush canopy that is naturally rounded. It requires minimal pruning to maintain its shape, making it a fantastic choice for beginners. Just be aware it is deciduous, so you’ll have a bare (but still structural!) form in winter.

The Japanese Umbrella Pine (Sciadopitys verticillata): The Evergreen Connoisseur

For a truly unique and elegant evergreen option, look no further than the Japanese Umbrella Pine. This isn’t a true pine, but it’s a magnificent conifer with long, soft, deep-green needles arranged in whorls that look like the spokes of an umbrella.

It is a very slow-growing tree that naturally forms a pyramidal or rounded shape over time. With some light pruning to clear the lower trunk and encourage a denser top, it becomes a spectacular, year-round focal point. It’s a long-term investment in your garden’s beauty.

Creating Your Own with Pruning: The DIY Approach

Feeling a bit more hands-on? You can create the mushroom shape on a variety of shrubs and small trees. This is where your inner artist can shine! Good candidates for this topiary project include:

  • Boxwood (Buxus): A classic topiary subject with small leaves and dense growth.
  • Yew (Taxus): A forgiving evergreen that tolerates heavy pruning.
  • Dwarf Alberta Spruce (Picea glauca ‘Conica’): Can be shaped into a beautiful, dense form.
  • Privet (Ligustrum): A fast-grower that will need more frequent trimming but establishes quickly.

The key here is to select a young plant with a strong central leader (a main upright stem) that you can develop into the trunk.

The Complete Tree That Looks Like a Mushroom Care Guide

Once you’ve chosen your tree, giving it the right care is essential for its health and the success of its shape. Think of this as the foundation for your beautiful living sculpture. This is a comprehensive tree that looks like a mushroom guide to get you on the right path.

Planting for Success: The Foundation

Where and how you plant your tree sets the stage for its entire life. Don’t rush this part!

Location, Location, Location: Most of these trees prefer full sun (at least 6-8 hours of direct sunlight per day) to develop a dense, symmetrical canopy. In scorching hot climates, a little afternoon shade can be beneficial, especially for Japanese Umbrella Pines.

Superb Soil: Good drainage is non-negotiable. These trees hate having “wet feet,” which can lead to root rot. If you have heavy clay soil, amend the planting area with compost or other organic matter to improve its structure and drainage.

Give It Space: Read the plant tag and plan for its mature width. Planting too close to a house, fence, or other plants will lead to a lopsided shape as it competes for light and space.

Watering Wisdom

Watering is a balancing act. Too much is just as bad as too little.

For the first year after planting, your tree needs consistent moisture to establish its root system. Water deeply once or twice a week, depending on your climate and rainfall. Once established, most are fairly drought-tolerant but will perform best with a deep watering during prolonged dry spells.

Pro-Tip: Apply a 2-3 inch layer of organic mulch (like shredded bark or compost) around the base of the tree, keeping it a few inches away from the trunk itself. Mulch is a gardener’s best friend—it helps retain soil moisture, suppress weeds, and regulate soil temperature.

Feeding Your Sculptural Tree

Less is more when it comes to fertilizer. A healthy tree doesn’t need a lot of extra food. Apply a balanced, slow-release granular fertilizer formulated for trees and shrubs in early spring, just as new growth begins. Follow the package directions carefully to avoid over-fertilizing, which can cause weak, leggy growth.

How to Prune for That Perfect Mushroom Shape

Okay, this is the fun part! Pruning is how you’ll create and maintain that signature look. Don’t be intimidated; with the right approach, it’s very straightforward. Follow these tree that looks like a mushroom best practices for great results.

The Right Tools for the Job

Using the right tools makes the job easier and is healthier for the tree. You’ll need:

  • Bypass Pruners: For small branches up to a half-inch in diameter. They make clean cuts like scissors.
  • Loppers: For branches between a half-inch and 1.5 inches. The long handles provide leverage.
  • A Small Pruning Saw: For any branches larger than 1.5 inches.

Before you start, always clean your tools with rubbing alcohol or a bleach solution to prevent the spread of disease. Sharp tools make clean cuts that heal faster.

When to Prune: Timing is Everything

The best time for major structural pruning is in late winter or early spring while the tree is dormant. It’s easier to see the branching structure without leaves, and the tree will burst with new growth to fill in your cuts when it wakes up.

Light trimming and tidying up can be done in late spring or early summer after the initial flush of growth.

Step-by-Step Pruning Technique

Here’s how to tree that looks like a mushroom using a simple, three-step process.

  1. Establish the ‘Stem’: Decide how tall you want the clear trunk to be. Carefully remove all branches and twigs growing from the trunk below that height. Make your cuts flush with the trunk, but be careful not to damage the slightly raised area where the branch meets the trunk, known as the branch collar.
  2. Define the ‘Cap’: Now, focus on the canopy. Your goal is a rounded, dome-like shape. Trim back branches that are overly long or stick out awkwardly. Imagine a sphere or dome and snip away anything that doesn’t fit within that imaginary line.
  3. Thin for Health & Shape: Finally, look inside the canopy. Remove any branches that are dead, damaged, or crossing and rubbing against each other. This thinning improves air circulation, which helps prevent disease, and encourages a denser outer canopy.

Remember to step back frequently during the process to look at the tree from all sides and ensure you’re creating a balanced shape. It’s better to cut too little than too much—you can always take more off later!

Common Problems with Tree That Looks Like a Mushroom (And How to Fix Them!)

Even with the best care, you might run into a few hiccups. Don’t worry! Here are some common problems with tree that looks like a mushroom and their simple solutions.

Lopsided or Uneven Growth

The Cause: This is usually caused by uneven sunlight (e.g., one side is shaded by a building) or simply neglecting to prune evenly.

The Fix: Prune the fuller, more vigorous side a bit more heavily. This will slow its growth and encourage the tree to direct more energy to the weaker, sparser side, helping it catch up.

Pests and Diseases

The Cause: Stressed trees are more susceptible to pests and diseases. Common culprits can include aphids, scale, or fungal spots.

The Fix: The best defense is a healthy tree! Ensure proper watering and air circulation. For minor pest issues, a strong spray of water from the hose or an application of insecticidal soap is an effective and eco-friendly tree that looks like a mushroom solution.

The ‘Trunk’ is Sprouting

The Cause: These are called suckers or epicormic sprouts. The tree is simply trying to grow branches from its trunk.

The Fix: This is an easy one. Just prune these sprouts off as soon as you see them. Rub them off with your thumb when they are small, or snip them flush with the trunk if they get larger.

Frequently Asked Questions About Trees with a Mushroom Shape

How long does it take to get the mushroom shape?

If you start with a plant like a Globe Catalpa, you have the shape instantly! If you are training a shrub like a boxwood or yew yourself, you can establish the basic shape in the first 2-3 years, and it will continue to get fuller and more refined with each passing season.

What’s the best small tree that looks like a mushroom for a tiny garden?

For very small spaces or even large containers, training a Dwarf Boxwood or a Dwarf Alberta Spruce is an excellent choice. Their slow growth and compact size make them perfectly manageable.

Can I make a fruit tree look like a mushroom?

Yes, you can! Dwarf apple or cherry trees can be pruned into a standard form. This is a great way to combine aesthetics with an edible harvest. Just be sure to follow pruning guidelines specific to fruit trees to ensure good fruit production.
