Financial analyst Plimsoll found 301 of the top 706 garden centre companies "are finishing the year in financial difficulty". There were 213 successful companies and 159 "serial loss-makers".
But Mintel said garden centres needed to look forward. It has predicted seven key consumer behaviour trends for the year ahead, looking at how this year's adversity created a new set of values.
In 2010, "resilience will define consumer behaviour, as people's strengthened resolve and changed behaviours shape new lifestyles", the company added.
Mintel director of foresight Richard Cope said: "While in 2009, fear played an important role in shaping consumer behaviour, 2010 will see a return of confidence and adaptation to overcome the restraints previously imposed on consumers.
"Balance has become the new mantra. As consumers find they are able to spend again, we'll see balanced spending and balanced consumption as key characteristics of next year."
In 2010, Mintel expects consumers to demonstrate an ability to recover from and adjust to any misfortune or change brought on by the recession.
People will face next year with better attitudes and strengthened resolve, learning new skills such as cooking, meal planning and DIY repair to cope with the "new economy."
Already, some 13 million Brits say they're cooking from scratch more often, while a quarter of Americans made their own home improvements to save money.
As many people still face unemployment, 2010 may see them looking to online educational tools to develop professional and social skills. Businesses that harness consumers' new resilient, education-driven mentality will benefit next year.
2. Reviewing and re-evaluating
The past year gave consumers cause to re-evaluate every aspect of their lives, looking for value and savings. Mintel research shows that in the UK, over half of Brits buy more on promotions and 28% have cut back on treats and luxuries.
In 2010, expect shoppers to keep reviewing as they hunt out the best deals and realise where they can get by on less.
Value initiatives are important and they'll remain so. However, consumers will purchase more expensive products if they are convinced of the products' value.
Brands that engage consumers effectively stand to be successful next year despite price barriers.
3. Prove it - accountability
Because consumer confidence worldwide took a hit this year, 2010 will see increased demand for proof and results.
People are tracking more areas of their lives through online forums, comparison sites and micro-blogging sites, so transparency is no longer a differentiator for brands; it's a requirement.
We've become a society of doubters, sceptical of nutrition claims, the motives of "green" companies and the competitiveness of bank rates.
A company's need for accountability is nothing new, but the quantity of information available today adds to the challenge.
Mintel predicts that in 2010, brands will need to pull out all the stops to gain consumers' trust.
The past year has meant a huge amount of economising and scaling back on previously normal treats and experiences.
While consumers have become accustomed to staycations, small indulgences and cooking at home, Mintel predicts they'll start occasionally breaking free from the tyranny of value in 2010.
Escapism will resonate both in and outside the home as consumers splurge on big purchases.
Savvy brands are already capitalising on people's desire to escape by offering new experiences such as 3D media and audio literature.
5. Media evolution
Micro-blogging, social networking and interactive media have exploded into consumers' lives, and as confidence in usage grows, people will incorporate new media forms more into their daily lives.
In the UK, nine in 10 adults have a computer in their home and in the US, four in 10 Americans have at least one social networking profile.
As people use new media to change and simplify daily tasks, they'll question the nature of authority and effective use of advertising.
Companies must work harder next year to truly engage, attract and interact with consumers, as media quickly evolves.
6. Ethical responsibility
In 2010, it'll be even more important to coax consumers out of their spending slumber and wean retailers off perpetual discounting.
Ethics will play a large part in rebuilding brands. Environmental and ethical issues still attract attention: nearly half of UK adults view them as important and 90% of Americans buy green products at least sometimes.
For businesses to rebuild brands through ethical efforts, they'll need to connect with consumers, giving them an emotional reason to buy.
As consumers demand more from the companies they do business with, they'll want ethical responsibility to be a chief concern, creating more scrutiny on ethical claims than ever before.
The past year left its mark: consumers are shying away from the spending binges of the past few decades and finding that moderation and preparation are possibilities.
Mintel predicts 2010 will be a year for increasingly seeking balance and readjusting to the "new economy."
As people accept the economy as it is now and embark on more balanced spending, they'll also stabilise other areas of their lives: food, diet, beauty.
Brands can capitalise by giving consumers multiple product options at different price and benefit levels.
