GOING GREEN – June 2025

Did you hear the news? Henley has received a Bee Friendly Award on National Bee Day in May. We achieved this award for the efforts made by various organisations, residential areas and businesses to become more ‘Bee Friendly’ in their grounds, window boxes or raised beds.

Across the town we had schools for all ages – pre-school, primary, secondary and Henley College were involved. Some churches, shops, charities, housing associations and residents groups all added to the sustenance and shelter needed for bees to thrive. Of course, Henley Town Council have played a major part in this as have Greener Henley who are working in partnership with the Council to maintain this recognition. Attaining Bee Friendly Status for the town was one of the Council’s strategy goals so we are pleased that we managed to do it within a year.

Obviously, what has been started is great but for it to be a real success for pollinators we should all be trying to improve the environment for all living beings. Everyone who has access to a scrap of ground can do something to make survival of native species possible. Because, of course, there is a very serious motive behind the fun of being Bee Friendly.

Often when people think of bees they are thinking of honey bees but as most of them are farmed by careful beekeepers they are doing alright. But some species of bumble bees and solitary bees, along with other pollinating insects are not doing so well.

Some bumble bees live socially in nests, not in the same numbers or with the same social hierarchy as honey bees. However some bumble bees are solitary bees and make their own nests (usually underground) to lay their eggs and provide food for the emerging grubs. The exception are the Cuckoo Bees who lay their eggs in other bees’ nests so they don’t have to provide food for them – just like the Cuckoo bird.

Solitary bees are different altogether. I have read that one Red Mason bee can pollinate 120 more flowers than a honey bee. They are our most proficient pollinators, with hoverflies coming in second.

The good thing about solitary bees and hoverflies is that even though they might look scary sometimes, they don’t sting and are not aggressive. For many of them the fact that they look like bees and wasps offers them some protection from predators, although that is not always the case.

The brilliant thing about hoverflies is that they are a gardener’s friend. They are attracted to flat shaped flowers particularly orange and yellow colours. Not only do they eat the nectar, they also lay their eggs on plants such as marigolds and nasturtiums. Their larvae are voracious eaters of aphids and other similar garden ‘pests’. That is why those plants are recommended as companion plants in a vegetable garden.

A prime source of pollen vital for the growth of some bumble bees are the native plants Bird’s Foot Trefoil and Red Clover. The loss of these species in meadows, (both members of the Pea family), is thought to have contributed to the decline in bumble bees. Broad beans and runner beans are also members
of the pea family. If you have plenty of bees in your vegetable garden you should have a good crop of beans.

Over the spring and early summer we have been growing some of these old meadow plants in pots as part of the Nature Squared and Bee Friendly Henley campaigns. We took the bulk of these to Henley’s Big Green Festival last week and have given some out to people in the area who may have space on a balcony or a doorstep but not the facilities to garden themselves.

We also had a few pots of oriental poppies, Devil’s bit scabious and a large campanula. All of these provide food for different insects at various times of the year and they all have different features that make them attractive to specific species.

What is so fascinating about nature is that everything has evolved and continues to evolve for all species to produce offspring and keep their species line going. That’s why there are so many different shapes, colours and scents of plants around us. If a flower’s structure is too complicated they will not be attractive to many insects and risk not being pollinated. Therefore each flower has evolved for pollination by some particular species, who likewise have evolved to be able to get enough food from plants for themselves and their young. Biodiversity is like a giant jigsaw where everything has its place.

For example some flowers have evolved to make use of ‘buzz-pollination’ which is a specific way of collecting pollen. The stamens of these flowers form a pointed central cone which will only release pollen when a bumblebee visits and vibrates their wings at a certain frequency. Only bumble bees and Anthopora bees like the Hairy-footed Flower Bee seem able to do this – not honey bees. Tomato, peppers, Borage and Geranium Phaeum all have flowers that need this kind of pollination.

Studies have shown that bees prefer orange and blue flowers whereas butterflies are more often attracted to pink or lilac coloured flowers. Flowers with small tubular centres appeal mostly to moths and butterflies. Aubretia, Hesperis (Lady’s Smock) and the Campian family (Dianthus) are typically favoured by moths and butterflies. The petals are flat so the insects use them as a landing platform while inserting their long thin probiscus into the small tube at the centre of the flower.

Plants like the red valerian which grows freely in this area is a favourite of the amazing Humming Bird Hawkmoth. Although the individual flowers are tiny they can push their long thin tongue into the centre of the flower to drink nectar.

You will have noticed that some flowers smell stronger at night, this is to attract night pollinators such as the night-flying moths. The RSPB recommends flowers with strong scents such as Nicotiana, Summer Jasmine, Hemp Agrimony, Sweet Rocket, Night-scented stock, Evening Primrose and Phlox.

I have noticed a lot more bees about this year, most probably because it has been dry and sunny for a few weeks as opposed to the wet season we had all last year. I was disappointed with my courgette harvest and I did notice that not all the female courgette flowers were pollinated in my garden. I put it down to lack of pollinators. This year I intend to grow some bee friendly flowers near the vegetable plot just to make it more attractive to bees. From what I have read, it is a good idea to mix up your flowers and vegetables especially for natural pest control.

For those interested in encouraging pollinators into your garden the advice is –

• Provide them with enough varied food, Access to water – a saucer with marbles or stones for bees and hoverflies
• Do not use chemicals in the space.
• Piles of brushwood or logs tucked under the undergrowth gives shelter
• or buy/make a bee hotel if you fancy doing some bee husbandry.
