Five Garden Design Mistakes You Must Avoid
A beautiful garden doesn’t happen by accident. It’s the result of careful planning, thoughtful planting, and a clear understanding of how the space will be used. However, many homeowners jump straight into buying plants or laying patios without seeing the bigger picture, often leading to disappointing results and a wasted budget.
At Green Acorn Landscape Design, we’ve been transforming gardens across the North West for over a decade. In that time, we’ve seen plenty of outdoor spaces that didn’t quite reach their potential due to a few fundamental errors.
The good news? These pitfalls are entirely avoidable. Whether you are planning a complete overhaul or a small renovation, steering clear of each common mistake will save you time, money, and stress. You can get it right the first time by avoiding these most common garden design mistakes.
Mistake #1: Not Having a Clear Plan Before Starting
The excitement of a new garden project is infectious. It’s tempting to head straight to the garden centre or start digging immediately. But failing to have a solid plan in place is one of the biggest garden design mistakes you can make.
Without a cohesive design, gardens often end up looking like a collection of disjointed features rather than a unified space. You might find that the patio is in the shadiest corner, or that a path leads nowhere in particular. This flighty approach often results in costly rework when elements don’t fit together as expected.
A well-thought-out layout is essential for a successful garden design, as it ensures the overall structure and arrangement enhance both aesthetics and functionality. A professional garden design creates flow, function, and long-term value. It considers how different zones connect, where the sun falls at different times of the day, and how the garden looks from inside the house.
Before you buy a single slab or shrub, ask yourself what you want to use the garden for. What kind of outdoor space do you want to create, and who will be using it? We recommend starting with the function, as the form will follow.

Mistake #2: Choosing the Wrong Plants for the Space
Even though planting is one of the most important elements of garden design, many homeowners do not give it much thought. Instead, they follow what looks good at the moment, only to find their beautiful flowers and luscious shrubs fading as soon as they bring them home from the garden centre.
Choosing plants, often in full bloom, based on appearances rather than their suitability to your specific garden conditions will lead to long-term issues and a garden that fades quicker than you’d like.
When choosing plants, you need to consider more than just their looks. You also need to consider scent, form, height, and seasonal features to determine whether they will enhance your garden’s ambience, provide year-round interest, and be suitable for the garden.
In terms of landscape conditions and maintenance, you also need to consider factors such as:
- Soil Type: Is your soil clay-heavy, sandy, or chalky?
- Sunlight: Does the spot get full sun, dappled shade, or deep shade?
- Drainage: Does the ground get waterlogged in winter?
- Exposure: Is the area sheltered or exposed to harsh winds?
This is why working with a professional landscape gardener can be so beneficial for your garden renovation. These local experts understand not only plants and their needs, but also the conditions of the region and what works best in these areas.

Once the plants have been chosen, this is not the end of the garden design mistakes. More garden design mistakes often appear in the planting and placement of your garden, with a specific concern for overcrowding. It is easy to plant young shrubs close together to make the border look full immediately, but this will not provide lasting structure or visual appeal in your garden. Closely planted shrubs will fight for space and nutrients, preventing any of them from reaching their full potential.
Likewise, choosing planting that requires a lot of maintenance when you lead a busy lifestyle will have similar long-term consequences. You want to ensure that your garden is suitable for your lifestyle and is something you can maintain without frustration for long-term success.
During your consultation with the garden designer, discuss your maintenance needs and interests so they know where you stand from the outset. They may tailor your planting to drought-tolerant, evergreen and perennials that provide lasting appeal without maintenance.
Landscapers can also create year-round gardens with a variety of blooming cycles. This ensures your outdoor space looks attractive throughout all seasons, without additional work.
Mistake #3: Forgetting About Scale and Proportion
Scale is one of the trickiest elements of garden design to master, yet it makes a huge difference to the final feel of the space. Failing to consider this is one of the biggest garden design mistakes you can make during your project.
For example, in a small garden, homeowners often make the mistake of using tiny pots, small plants, and small paving slabs, as they think smaller features will make the space look bigger. In reality, relying on too many small plants can make the space feel cluttered, while fewer, larger elements can help a small garden feel bigger and more expansive. Conversely, in a large garden, a tiny patio or a narrow path can look lost and uninviting.
Balance is key in garden design, and is one of the key principles of the art. Focusing too much on small things can reduce the overall impact and harmony of the garden.
Your hardscaping, such as the patios, paths, and walls, needs to sit comfortably alongside your softscaping, like the lawns, plants and trees. A professional eye ensures that planting heights, paving sizes, and garden structures are all proportionate to the size of your home and the garden boundaries.

Mistake #4: Overlooking Drainage and Ground Preparation
It’s not the most glamorous part of landscaping, but what happens underground is just as important as the beautiful finish on top. Ignoring groundwork and drainage is a recipe for disaster and one of the major garden design mistakes we see many homeowners face, especially when attempting a DIY project.
If you lay a new patio without the correct sub-base, it can sink or crack over time. If you ignore drainage issues, you might end up with a lawn that turns into a swamp every winter, or worse, water pooling against your house walls.
Proper soil preparation also helps your garden retain moisture, supporting healthy plant growth and preventing drought stress.
Professional landscaping is about building from the ground up. At Green Acorn Landscape Design, we ensure the correct preparation is done before any aesthetic work begins. This ensures your garden doesn’t just look good on day one, but remains durable and usable for years to come.
This is why asking about drainage and groundwork is one of the most valuable questions you can ask a landscaping company before hiring, as we explore in our post 10 Questions to Ask a Professional Landscape Gardener Before Hiring.
Failing to prepare or address groundwork, drainage, and foundations will only lead to long-term hassle. It will be expensive to repair and means your current garden design is a poor investment. Professional landscapers, like our team, will outline all stages during the consultation and planning stages for peace of mind.
Mistake #5: Designing for Looks Instead of Lifestyle
Inspiration photos and ideas, such as our post 5 Stunning Landscaping Ideas for Warrington Homes, can be a useful tool at the beginning of your landscaping project. However, replicating a show garden that doesn’t fit your actual lifestyle is one of the leading garden design mistakes.
A stunning, minimalist garden with white rendering and pristine lawns might look incredible in photos, but is it practical if you have two muddy dogs and three energetic children? Similarly, a cottage garden packed with delicate perennials is beautiful, but requires hours of weekly maintenance that you might not have time for.
Lifestyle-led design prioritises usability. It considers practicalities like:
- Where will the bins go?
- Is there enough storage for bikes and mowers?
- Is there a well-placed seating area that offers comfortable seating, privacy, and enjoyment where the sun hits in the evening?
- Is the access suitable for wheelbarrows or wheelchairs?
During a consultation with a professional garden designer, both your practical needs and aesthetic vision will be discussed. This allows us to tailor all decisions moving forward to your requirements, creating a garden that is just as functional as it is beautiful. When your garden works for your lifestyle, you will find yourself using it far more often.
