Choosing Trees for Small Gardens

Expert Advice on choosing right trees for small gardens from Plymouth Tree Surgeon

Small gardens have a lot to offer — charm, intimacy, and the opportunity to create a personal oasis right outside your door. But when it comes to planting trees in compact outdoor spaces, many homeowners worry about selecting the right trees for small gardens, managing root spread, or accidentally choosing a tree that will eventually overwhelm the space.

At Plymouth Tree Surgeon, we regularly assist clients across the South West with carefully choosing and planting trees that thrive in small gardens. Whether you’re seeking beauty, privacy, or seasonal colour, there’s a tree out there that can suit your garden’s size and style.

Why Trees Belong in Small Gardens

Even in the tiniest garden, the presence of a well-chosen tree can provide structure, shade, movement, and seasonal interest. A tree draws the eye upward, making the space feel taller and more layered — a clever trick for visually expanding a compact area.

Here are just a few benefits of planting a tree in a small garden:

• Aesthetic Value – Trees offer colour, texture, and architectural form. Even a single tree can dramatically elevate the look of your space.
  
• Increased Privacy – Trees act as living screens, helping shield your garden from neighbouring windows or busy streets without the harshness of a solid wall or fence.
  
• Biodiversity Boost – Trees attract birds, bees, butterflies, and other beneficial wildlife, helping your garden become a mini sanctuary.
  
• Environmental Impact – Trees absorb carbon dioxide, improve air quality, and support rainwater absorption, reducing runoff and erosion.
  
• Cooling Shade – Strategically placed trees can cool your home in the summer and shield it from wind in the winter.
  

With thoughtful planning, even a single small tree can bring life, beauty, and structure to your garden — while still leaving space for patios, flower beds, and seating.

Factors to Consider Before Planting a Tree

When space is limited, every decision matters. Before heading to the garden centre or nursery, take a few moments to evaluate the space and the conditions of your garden. A tree that’s perfect for one garden might be completely unsuitable for another.

1. Mature Size and Shape

Don’t be fooled by a sapling’s size — think 10, 20, or even 30 years ahead. Always check the mature height and spread of the tree to make sure it will still fit comfortably in the space without dominating it.

Tip: Look for dwarf, columnar, or slow-growing varieties that naturally stay compact without excessive pruning.

2. Light Levels

Pay attention to how much sun your garden receives. Does it get morning sun, full midday exposure, or is it mostly in shade? Some trees, like Japanese maples, prefer partial shade, while others, like crab apples, love full sunlight.

3. Soil Type

Soil plays a huge role in a tree’s success. Sandy soils drain quickly but lack nutrients, while clay soils retain water but can become compacted. If you’re unsure of your soil type, a tree surgeon can help test it and suggest suitable trees or amendments.

4. Drainage

Roots hate sitting in water. If your garden tends to get waterlogged, you’ll need to look for trees that tolerate wet feet or improve drainage before planting.

5. Proximity to Structures

In small gardens, trees are often close to homes, walls, patios, and underground utilities. It’s essential to pick species with non-invasive roots and avoid those that will push up paving or damage foundations.

6. Maintenance Requirements

Some trees require annual pruning, leaf collection, or pest management. If you’re looking for something low-effort, pick a variety with neat growth habits and disease resistance.

7. Purpose and Style

Think about your overall goal: Do you want colour in autumn? Flowers in spring? Screening from neighbours? A fruit tree? Choosing with purpose helps ensure long-term satisfaction.

Can You Grow Trees in Containers?

Yes, and it’s often the perfect solution for small gardens, patios, or even balconies. Growing trees in containers helps control size, limits root spread, and offers flexibility if you want to move the plant or redesign your space later.

Best Trees for Pots:

• Olive trees – Mediterranean appeal and easy to shape
  
• Bay trees – Versatile and aromatic
  
• Dwarf fruit trees – Apples, cherries, or plums on miniature rootstock
  
• Japanese maples – Thrive in containers with the right soil
  
• Topiary evergreens – Provide year-round structure

Container Tree Tips:

• Use a large pot (at least 45-50cm in diameter)
  
• Add good drainage (broken crocks or stones at the base)
  
• Use loam-based compost for stability
  
• Water and feed regularly
  
• Re-pot every few years to refresh nutrients and prevent root binding
