Fed Up With Smog? 5 Pollution-Resistant Plants to Help you Breathe

As the government pledges the funding of millions of trees in cities to ease pollution, an expert offers a guide to 5 smog-resistant plants.

The government is proposing to fund the planting of millions of trees to boost housing prices in cities, to improve green spaces and help preserve the environment, gardeners can also do their bit by planting pollution-resistant plants.

David Mitchell, buying manager for horticulture at Wyevale Garden Centres, says: “Plants do have a hard time with pollution. Since the leaves need to ‘breathe’, anything that limits that exchange, such as airborne gasses or if the pores are blocked by dust and grime, will limit their potential.

“Fruit trees in particular can struggle and yields can be as low as half of what they would be in cleaner air.”

Here are five of his favourite pollution-tolerant plants and how to care for them…

pollution resistant plants

1. Pyrus calleryana ‘Chanticleer’

This ornamental pear is an exceptionally good tree for small urban gardens, with its upright, narrow shape and branches that are smothered with white blossom early in spring (April to May).

The leaves turn a vibrant red and purple in the autumn before falling and some years, the tree will produce small inedible brown fruits. It does best in moist but well drained soil (clay, sand or loam) and in full sun.

2. Buddleia

Known as the butterfly bush, Buddleia produces clusters of deep scented flowers from midsummer into autumn. Rich in nectar, this fast-growing, hardy deciduous shrub attracts butterflies, bees and other insects, and thrives in any well-drained soil (chalk, loam or sand).

3. Camellia

Producing rich, colourful flowers with ruffled petals and golden stamens in late winter into spring (February to April), which are offset by glossy evergreen leaves, the camellia proves that beautiful plants can also be tolerant to pollution.

Plant in light shade, in shelter, and in moist but well-drained, humus-rich, lime-free soil (loam) or in a container, in ericaceous (lime-free) compost.

4. Buxus sempervirens

This classic British native evergreen is ideal for low hedging, boundaries or divisions in formal gardens in both modern and traditional settings.

It responds well to being trimmed and thrives in the shade, and most well-drained soils (chalk, loam or sand). It’s excellent for growing in containers, as topiary and for training as feature plants.

5. Berberis

This easy-to-grow barberry has spiny shoots and simple leaves. Soft yellow or orange flowers appear in spring (April to May) and are followed by small berries in the autumn. This deciduous or evergreen shrub will succeed in a wide range of conditions. Plant in full sun or partial shade in well-drained humus-rich soil (chalk, loam or sand), although it will be tolerant of most soils as long as they are reasonably well-drained.

5 Last-minute garden jobs to do before winter arrives.

Almost time to batten the hatches before winter arrives - but you still have time to do last-minute garden jobs to beat the winter chill.

5 garden jobs before winter

You may have been enjoying the balmy autumn, but as the sweaters and woolly socks come out, it’s almost time to put the garden to bed.

So, what last-minute jobs should you be doing?

5 jobs for garden

1. Shelter vulnerable plants

My pots of geraniums (pelargoniums) are still going strong but they won’t be for much longer, so if you want to keep them for next year, find them some shelter now.

Cut them back to 10cm (4in) and put pots in a light, frost-free place such as a greenhouse or a sheltered porch next to the house. If the spot isn’t completely frost-free, wrap the pots in bubble wrap to give them extra protection.

If you’ve a conservatory or a cool spare room, even better. Don’t put plants near central heating or they will wilt and die when you bring them out next year.

Do the same with fuchsias, cutting them back before you put them under cover for winter, and hardly water them at all until growth starts again in spring.

2. Divide perennials

The ground should still be soft enough to dig up overcrowded clumps of perennials and split them, replanting the divided clumps to give them more space.

This will lead to better performance in subsequent years and you’ve also increased your stock. Repeat planting is really effective at creating continuity and flow in borders, and dividing perennials is an ideal way of doing this.

Good subjects for division include crocosmia, rudbeckia, helenium, cranesbill geranium and catmint. You can also lift and divide hostas, although you’ll need a sharp knife to slice through the thick, congested roots.

3. Trim hedges

Try to do this when the weather’s still fine – you don’t want to be getting the hedge trimmer out when it’s pouring. If you tidy evergreen hedges now, they will look neat until next year as they won’t put on much new growth during the cooler months.

Also, trimming now may save you a bigger job in spring, when you also risk disturbing birds’ nests. Deciduous shrubs can be pruned into winter.

4. Get rid of the last of the weeds

Try to dig out any pernicious perennial weeds you see lurking, such as bindweed, couch grass and ground elder. You’ll need to dig them out completely, root and all, as if you leave any fragments of root in the soil they will come back in spring.

Hopefully, if you dig up the perennial weeds now, your job won’t be as arduous in spring. If you have areas which have been totally invaded, consider covering the ground with sheets of black plastic, secured with bricks at each corner, which will stop the light and hopefully kill the weed in a few months.

5. Take cuttings

Want to increase your stock? It’s a perfect time to take hardwood cuttings of shrubs including weigelas, roses, dogwood, philadelphus and willow. They can often be grown on outdoors in a prepared trench.

Select vigorous, healthy shoots grown in the current year and remove the soft tip growth. Cut into sections 15-30cm (6in-12in) long, cutting cleanly above a bud at the top, with a sloping cut to shed water and as a reminder which end is the top.

Cut straight across at the base, below a bud or pair of buds. Dip the base into hormone rooting powder, make a slit trench in a well cultivated but vacant area of the garden, push the cuttings in vertically, 30cm (12in) apart and firm the soil back around them, closing the trench.

Water them in. This time next year they may have rooted enough to be moved. This job can be done at any time between mid-autumn and late winter.

Ghoulish Halloween Gardens!

Getting in the Halloween spirit? Hannah Stephenson reveals some of the 'foul and creepy' specimens that could be lurking in your hedges and borders...

halloween garden design plants

Mischievous trick-or-treaters dressed as ghosts and ghouls may be on the prowl on your doorstep this Halloween – but step into your garden and you might find some spooky spikes, noxious nasties and creepy creepers lurking in your borders.

Some plants can sting, burn, cut or emit an acrid, foul-smelling odour. Others have sinister-sounding names or connections with witches or the devil, while there are some which are said to help ward off evil.

Get yourself into the mood for Halloween with this guide to horticultural horrors…

1. Eye-poppers

When you see the spooky white berries with a single black spot emerging from red stems, you can understand why this sinister-looking plant is nicknamed the Doll’s Eye (Actaea pachypoda). All parts of this herbaceous perennial are poisonous and when ingested can cause hallucinations.

2. Strangling suspects

Also known as strangleweed, devil’s guts, witches shoelaces and devil’s ringlet, but better known as dodder (Cuscuta), this pernicious relative of bindweed twines itself round a host plant and inserts itself into the host’s vascular system – sucking out everything it needs to live and killing its plant victim in the process.

3. Prickly subjects

Among the most prickly of plants is the hawthorn. As a thorny hedge, it will stab its thorns into your fingers, even when you’re wearing the toughest gloves, and mature plants will even pierce the soles of gardening shoes – although on the plus side, a hawthorn hedge can also deter even the most persistent burglar.

Other prickly candidates include creeping juniper, common holly, firethorn (pyracantha), juniper and purple berberis.

4. Toxic terrors

Aconitum, also known as monkshood or wolfsbane, is among the most toxic of plants, with ingestion of even a small amount causing severe stomach upsets. But it also slows the heart rate, which can prove fatal.

You don’t just have to eat it to suffer the symptoms. The poison can be absorbed through the skin, via open wounds, and there have even been reports of people feeling unwell after smelling the flowers.

5. Foul smelling specimens

Then there are the plants which literally smell like rotten corpses. The stinking iris, Iris foetidissima, for example, absolutely reeks. If you can stand the smell, or remain downwind from it, this bulb puts on a spectacular display in autumn and winter, when its gigantic seed pods burst open to reveal brilliant orange and sometimes red seeds.

6. Acrid arums

The titan arum (Amorphophallus titanum), also known as the ‘corpse flower’ as it smells like decomposed bodies when in flower, is nevertheless beautiful, growing up to 3m tall, its gigantic crimson flower spanning 3m, and is a great magnet for pollinating insects.

This acrid arum prefers the rainforests of Sumatra as its natural habitat, although you can admire it in the exotic sections of botanical gardens such as the Eden Project in Cornwall and at Kew, where it’s currently flowering.

Others in the bad smells league include Eucomis bicolor, the pineapple lily, and the dead horse arum (Helicodiceros muscivorus), named for obvious reasons.

7. Ghostly apparitions

The ghost plant (Monotropa uniflora), an eerie white specimen found in shady woods is a rare sight.

It has no chlorophyll, the chemical that allows plants to absorb energy from the sun and typically gives plants their green colour. In fact, the ghost plant is a parasite which sucks on fungi connected to a host plant, which is usually a nearby tree. The fungi acts as the middleman for the nutrients provided by the tree.

8. Bizarre bulbs

While many bulbs bring heady fragrance, including the sweetly-scented hyacinth, others have pretty horrible odours, including the imposing crown imperial (Fritillaria imperialis). But don’t let the smell put you off too much, because its impressive orange flowers make more of a statement than its whiffy pong.

9. Poisonous potions

No Halloween would be complete without its share of witches, whose potions have been linked with some of our most common plants. Hemlock, for instance, is highly poisonous and closely linked with witchcraft. It doesn’t look significantly different from the hedge parsley or cow parsley which grows along roads, ditches, trails, or the edges of fields.

Its white flowerheads resemble those of parsnips, carrots or angelica, while the bright green leaves are deeply-cut, even feathery and delicate. Yet all plant parts are poisonous, with the seeds containing the highest concentration of poison, causing toxic reactions.

Deadly nightshade (Belladonna), another common plant often found in hedgerows, was one of the main ingredients in witches’ brews during the Middle Ages, while blackthorn is often referred to as a witch’s tree. As late as the 1940s, anyone seen to carry a blackthorn walking stick was suspected of being a witch.

10. Warding off evil

Plants including rowan (Sorbus aucuparia), hazelnut (Corylus avellane) and elderberry (Sambucus nigra) were once thought to be ‘magical’ trees and shrubs, which could ward off witches and evil spirits.

Ancient Celts believed rowan berries gave good health, and that if you planted them near grave sites, they would help the dead sleep.

People would use branches as dowsing rods and make crosses of rowan twigs to protect themselves on Halloween, while in old Europe, householders would put elderberry branches above their doorways to protect their homes from malevolent spirits. Strands of hazelnuts, worn or kept in the home ,were said to bring good luck.

8 Tips for Giving your Garden a Late Summer Spruce-up

end-of-summer, garden-tips, autumn-preparation

As the season draws to a close, it’s time to clear patio debris, replace tired plants and restore order to your outdoor space. By Hannah Stephenson.

Back from your summer travels? Are your hanging baskets looking a little sorry, your pots pathetic and your borders brimming with weeds? Here are some easy but effective garden tidy-up tips…

  1. Save it

Save what you can, deadheading late-flowering blooms in borders which may come back to life. Perennials which have finished flowering can be cut back but will come back to life next year. Established trees and shrubs won’t generally have been damaged in your absence.

  1. Ditch it.

If your hanging baskets and pots of annuals have completely dried out, take them down and empty the contents onto the compost heap. Keep your spirits high by buying spring-flowering bulbs and, if you want late colour, pop into the garden centre to find some.

Good plants which will bring colour at this time of year include asters, chrysanthemums and nerines, along with rudbeckias and sedums. Plant some in the pots that are now free from wilted summer annuals.

end-of-summer, garden-tips, dead-heading
  1. Tend to the lawn.

With the hot summer we’ve had, the lawn might be looking like hay and shouldn’t need cutting. If it has grown substantially though, leave the blades on the highest setting for the first cut, reduce the height at the next a few days later, and then cut at the normal height. You’ll be surprised how much tidier the garden looks when the lawn has been mown. Take time to tidy up the lawn edges using edging shears.

  1. Lose the weeds.

Look over your beds and borders and if weeds have sprung up, then get rid of them quickly. Seeds shed at this time of year, which means more work later on. Keep on top of deadheading, otherwise the flowering will not continue as long as you’d like.

  1. Harvest now.

If you have a vegetable patch, harvest as much ripe produce as you can now, to stop the veg running to seed or becoming over-ripe. You can blanch (immerse in boiling water) and freeze many veg, including green beans and sweetcorn, so you don’t end up wasting what you pick.

Immerse the vegetables immediately into a bowl of iced water after blanching, to stop them continuing to cook. When cool, lift the veg from the iced water, spread out on a kitchen towel and pat dry to remove excess moisture. Pack loose vegetables in resealable plastic bags or other containers. Vegetables suitable for freezing include beans, broccoli, cauliflower, corn, peas, spinach, Swiss chard and summer squash. Even tomatoes can be frozen whole and then used in sauces and soups later on.

  1. Clear space for new crops.

Find time to clear vacant rows in the veg patch and refill them with autumn and winter crops as soon as you can.

  1. Put away pots for winter.

If you have empty pots you’re not going to use again this year, clean them with diluted disinfectant and stow in the shed for winter. That way, terracotta won’t crack and other vulnerable pots won’t perish when the frost comes. Also, remove and put away stakes which propped up plants which have now been cut back.

  1. Plan for next year.

Take time to write a list of what you are going to include and exclude in your plantings next year. Look for gaps you’ll need to fill in borders next season, and maybe extend the season by planning to plant some perennials which provide late-summer colour.
