The scary stuff!
You’re still here… After four chapters, you’re still here! Thank you! I truly wish this was the part where sit back and share a glass of your favourite tipple and reminisce about a job well done. Sadly not. There’s no way of sugar coating this. The catastrophic collapse of our insect and invertebrate populations is happening. It’s undeniable.
Actually, it’s been going on for decades!
The most recent UK’s State of Nature Report and a flood of research has proven that insect numbers are in decline across the board: “Pollinators such as bees, hoverflies and moths, have decreased by 18% on average, whilst predatory insects, like the 2-spot Ladybird which help control crop pests, have declined by 34%1. Since 1970 more than half of our flowering plants, mosses and their relatives have been lost from areas where they used to thrive1” (State of Nature 2023)
Here are just a few of the headlines sourced over recent weeks:
“In the UK, we have already lost around 13 species of bee and another 35 are currently at risk. Nearly 1 in 10 of Europe’s wild bee species is facing extinction.” (https://friendsoftheearth.uk/nature/what-are-causes-bee-decline)
"Every square kilometre in the UK has lost an average of 11 species of bee and hoverfly, between 1980 and 2013” (Dr Lynn Dicks, University of East Anglia)
“Butterflies are at their lowest ebb on the back of 50 years of decline” (Dr Richard Fox, Butterfly Conservation)
“33% of (butterfly) species had shown a significant decline in their abundance on monitored sites in the UK over the past 48 years. It’s quite simple really – there’s not enough habitat and what is there isn’t good quality,” (Dr Marc Botham, UK Centre for Ecology and Hydrology)
“Some 35% of global crop production and more than 85% of wild flowering plants rely to some degree on pollination. 85% of plant species are insect pollinated but 40% of insect species are at risk of extinction” (SUPER-B, Sustainable Pollination in Europe http://superb-project.eu/)
At times, it feels completely overwhelming, doesn’t it? When I was researching this piece and looking through the statistics, there was more than just alarm bells ringing in my brain. There was also outrage, guilt and a whopping great sickening dollop of shame. By the way, if you’re looking to validate these statistics above, I’ve linked to the reports at the end.
They all make for stark and bitter reading! But they beg the question, how do we combat such loss? The loss of habitat across UK and beyond? One of the most widely-publicised statistics is that in the last 90 years we have lost 97% of British wildflower meadows. At the top level, it's the Government and Industry and they’ll be at loggerheads for decades, but one feels they will always wriggle out of any commitments! Just call me cynical. Even with a groundswell of voters and legions of customers demanding change, it’s like trying to turn an oil tanker at full speed. It will take time, but time is in desperately short supply.
Iconic habitats like the meadows are not the only losses. Home and property owners have played their part too. Looking closer to home, according to the RHS 2015 Greening Grey Britain Report, over five million front gardens had no plants growing in them. Over 7 million were nearly totally paved over.
I’m dumbfounded by this. I remember as a kid, our local streets were lined with row upon row of modest front gardens. Some, just a lawn with a massive pampas grass (like ours) or a mophead hydrangea. Many with regimented tiny borders of bedding, but rich with blooms. Carefully tended little lawns. So many roses! And yes, the odd gnome or two.
Over the last 20 years they have all vanished. Replaced by brick pavers and tarmac to park our cars. It represents a dramatic loss in potential ‘nature’ real estate, not to mention creating even more hard landscaping where rainwater flows off into an already overwhelmed drainage system. Maybe a discussion for another time.
Individually we are small. Collectively, we are vast!
Now for a little positivity. Thank goodness! Bees and other pollinators don’t recognise boundaries like walls and fences, even though we humans defend them without mercy. They don’t care whether flowers are planted in naturalistic swathes in vast serpentine borders, whether they are in regimented rows of a cutting garden, or a modest collection of pots or a window box. Pollinators see and sense flowers and blossom, irrelevant of postcode or garden design. They don’t discriminate between a row of bijou gardens or a field that stretches to the horizon, as many city rooftop gardens and apiaries can attest!
Did you know that roughly 87% of UK households have gardens?2 The average size of a UK garden is 190m² (2000ft²). Just imagine, if you will, all the gardens of the country lined up together… How much space for pollinator-friendly plants would that create? A few hundred square kilometres? Not even close! There is an estimated 4,300 square kilometres or 1,600 square miles, approximately three times the size of Greater London or a fifth of Wales! If you took England’s gardens alone, collectively they would cover all the National Nature Reserves four times over!3
Surely, amongst all those monumental figures...
...all that potential green space, there is room for pollinator boosting gardens? And there is definitely hope. Estimated household spend on gardening in the UK expected to reach over £6.5 billion5 with 87% of gardeners wanting to attract more wildlife4. Hoorah! I implore you to use those hard earned £££s to welcome nature’s richness into your green spaces and provide our essential garden friends with desperately needed food and essential quality habitat.
Avoid paralysis
Try not to be snared by the honeyed trap of analysis paralysis. If you want to improve the richness and diversity of pollinators visiting your garden, now is the time to act. You can start with something fun! By shortlisting plants that you like and may want to add next season. Perform a quick online search and see how well they match-up against the needs of pollinators. There are dozens, if not hundreds of great articles online, detailing the best garden plants for pollinators. Start with the RHS and go from there. You will be able to find what you’re looking for! I promise!
If you lose plants over the winter, replace them using that same shortlist in spring. Gradually, through natural winter losses (that we all experience), you will transform your garden into a pollinator paradise. Be sure to leave room on your shopping list (for mature plants, plugs, seeds, or bulbs) for early and late flowering plants too, so you can extend the flowering season - a boon for gardeners and pollinators alike.
This is one of the best resources I’ve found because it details which bees favour each plant listed. Of particular interest if you’re looking to encourage certain species into your garden.

Food plants?
Pollinator plants are fantastic, but what about food plants for butterfly and moth caterpillars? The greater diversity of plants in your garden the more chance there will be that you’ll have a food source. Here, native plants really are invaluable but cultivars and ‘relatives’ of our natives are also on the menu. Native trees have enormous value and that also includes trees that might be lining your street. If you’re considering a hedge, be sure to include a range of natives along with the ornamentals. If you can leave a small wild and weedy patch, all the better. The list is extensive and you’ll probably have a few already. But have a read through this excellent resource and maybe you have room for a few more? In essence we're trying to build habitat for pollination, food for larvae, and cover.
By the way, are you ready to go ‘back to the Fuchsia?’ (See what I did there?) Fuchsias are a favourite food plant of the impossibly beautiful Elephant Hawkmoth (Deilephila elpenor)
Attack apathy
Avoid that sticky mess of apathy. We can improve the situation! According to the UK Pollinator Monitoring Scheme, some bumblebee and solitary bee species are doing well and have increased their distribution in Britain. “Bumblebees and solitary bees that are able to collect nectar and pollen from a wide range of plants, including garden flowers, are thought to be maintaining their numbers and distribution.” It's the specialists that are in real trouble!
Top 10 garden plants for specialist bees
- Bellflowers (Campanula species)
- Yellow loosestrife (Lysimachia vulgaris)
- Willows (Salix species)
- Lamb’s ear (Stachys byzantina)
- Ivy (Hedera species)
- Scabious (Knautia, Scabiosa and Succisa species)
- Mignonette (Reseda species)
- Dandelions and relatives (Taraxacum officinale agg. and others)
- Buttercups (Ranunculus species)
- White bryony (Bryonia dioica)

More positive steps
Plant more spring bulbs to provide energy for those early emerging bumblebees and solitary bees. Snowdrops, crocus, winter aconites, and iris reticulata are among the earliest. Also look at hellebores, viola, winter-flowering honeysuckle (Lonicera fragrantissima), mahonia, and Viburnum tinus for winter flowers. Forget the bedding plants! Pansies, begonias, and busy lizzies are poor resources for pollinators, bringing little benefit. There are better options!
Add more variety and diversity to your garden with flowering (blossom) trees, shrubs, perennials, and annuals that flower in succession throughout the entire year. Keep deadheading those herbaceous plants to keep them flowering for longer.
If you do have the space, plant flowers of the same type together in clumps, swathes, ribbons, whatever your design aesthetics are. Just like tree blossom, packing in the same flowers will help winged-pollinators save energy moving from flower to flower more efficiently.
If outside space is at a premium or you’re renting, you can fill window boxes, hanging baskets, pots and planters with a range of plants, whether you’re on the ground floor or the top. Don’t forget those vertical spaces for flowering climbers. Planting flowering mediterranean herbs like rosemary and thyme in pots will serve two roles, one for the pollinators and one for the kitchen. They’ll also cope with drier conditions too. Dwarf fruit trees and fruit bushes are equally at home in pots or trained against walls, especially if you have plenty of sunshine.
Relinquish areas of your lawn (however begrudgingly) and give them over to flowering borders or wilder swathes of grass. Remember, it doesn’t have to be native grasses and wildflowers, although that is truly wonderful if you can. You can plant all manner of wondrous bloomers in your lawn! (Now chuckling at the thought of ‘wondrous bloomers’ on the lawn)
Provide cover for overwintering pollinators by leaving twiggy woodpiles and plant stems or piles of autumnal leaves swept into a corner. Old tree stumps, ivy-clad walls, a patch of unmown grass, and plants left standing all winter (not being cleared in autumn) are all incredibly valuable for all manor of insects and invertebrates.
Stop routinely digging your garden soil. Many of our bees need undisturbed soil for their underground nest chambers or winter hibernation burrows. By digging over soil in the autumn or spring, you risk killing hibernating Queen bees or even disturbing nests of active bees, such as the Buff-tailed bumblebees (Bombus terrestris)6.
For goodness sake, for the love of all that you cherish, take all the poisons and chemicals from your shed or garage and dispose of them. Safely. You do not need them. The widespread and indiscriminate use of pesticides and herbicides are a massive issue. Besides, the garden will find a natural balance without us interfering and fussing. Please trust me and every other organic gardener and grower.
The takeaways
Okay, this gargantuan series is nearly over and we haven’t even touched the other wild and wonderful inhabitants of our treasured gardens. However, I sincerely hope you will acknowledge the calamity, but also take away the positives. Us gardeners can be a powerful force for good and for positive change. Collectively our gardens cover a massive area of land! Just think of how many ‘meadows’ we could create! How many pollinator corridors we could amass? We can have a beautiful garden that enriches our heart and pleasures our mind, yet provides food and cover for nature. You can have fun devising new planting schemes and who doesn’t like plant shopping?! Learn about our fascinating pollinators and prepare to be astounded!
Lastly, you will be amazed just how quickly pollinators will find your new pollinator power plants. If they’re in bloom, sometimes it's just a matter of seconds! Literally! No joke… I’ve taken new plants out of the car, set them down, and by the time I’ve closed the boot, there are bees already seeking the nectar. Change can be as quick as that!
