Be daring with

dahlias! Dahlias are at their brilliant best right now – here’s how to get the most out of them in your garden EVERYONE LOVES A dahlia, especially at this time of year when they’re at their Clare vibrant flowering Foggett peak. But once you start growing them EDITOR you soon realise just how many colours, shapes and sizes are available when it comes to choosing flowers. The trick to making them look good in the garden is how you use that massive range to your

advantage. With such striking blooms, dahlias can be tricky to integrate into a border, but if you pick the right colour to go with your existing plants, and a flower shape that works with the textures and shapes around it, you’re onto a winner. It’s fine if you’re an exhibitor – then you can just grow them in rows with paths between to help you pay your plants the attention they need for showing. But if you simply want to grow dahlias for the colour and vibrancy they bring to the garden, you need to plan how you plant them a bit more creatively.

single daisy-shaped flowers such as rudbeckias or echinaceas, but with tonnes more exciting colour options, dahlias open the door to lots of different schemes. Some of the best known dahlias have simple, open flowers such as ‘Bishop of Llandaff’ with its postbox-red blooms and all the other ‘Bishops’ such as yellow ‘Bishop of York’ and magenta ‘Bishop of Canterbury’. Then there’s ‘Moonfire’, a yellow singleflowered variety with a striking red halo around the centre of the petals. The thing that the Bishop dahlias and ‘Moonfire’ have in common is colourful foliage in

deep, dark purple giving you an added element to play with. Red ‘Bishop of Llandaff’ looks good with purple flowers, which complement not only the dahlia’s flowers but its dark foliage too. Try mauve asters, Verbena bonariensis, royal purple Phlox paniculata such as ‘Le Mahdi’ or purple-leaved Ricinus communis ‘Carmencita’. Almost without trying you’ll have created a planting scheme that feels a bit jungly – make it deliberate by mixing in a few cannas for their tropical leaves or amaranthus (love-lies-bleeding). ‘Bishop of Llandaff’ cries out to

3 diﬀerent ways to use dahlias

1 Create colourful herbaceous borders Pack dahlias in among other perennials such as day lilies, alstroemeria and phlox for borders with style.

2 Make a contemporary prairie scheme Mix them up with bronze and golden grasses for a contemporary take on the traditional border.

3 Mix them with riotous bedding on the same flower! Now that might be hard to integrate into a border, but try it with perovskia, the small grey-leaved shrub with elegant spires of silvery-blue or simple white Japanese anemone ‘Honorine Jobert’.

Team dahlias with your summer bedding in pots and borders for displays that need sunglasses!

Double the fun Dahlias that have flower types described as waterlily and decorative have fully double blooms, which means they deliver much more impact in the border. If you want to pack a really colourful punch, these are the ones to go for,

You can also find singleflowered dahlias that suit cooler colour schemes. ‘Twyning’s After Eight’ is a lovely combination of dark chocolate foliage and white flowers. Try it with fluffy pink amberboa and upright pink salvia spires.

Sow your free nigella ‘Miss Jekyll’ seeds

EN IN THE FLOWER GARD

Still ti m e to... Prune wisteria

2014 sEEd collEctioN

£1.8P5

Love-in-a-mist (nigella) is a super hardy annual to use as a cut ﬂower and it also pulls its weight at the front of a border among showy perennials. Once sown it will seed itself. The seedpods add Nigella a feathery-leaved elegance to ‘Miss Jekyll’ your garden every late summer. Sow in a sunny spot with well-drained soil and the seedlings will overwinter, with Easy-to-grow delicate lovein-a-mist the potential to ﬂower early Ōowers in preŏy sky blue next summer. If you want them in a border, clear some spaces and mix the seeds with sand so you can see where you’ve sown them. Try sowing in circles, squares or curves.

A wisteria can quickly take over if it’s not pruned regularly, but it’s easily tackled in two stages. At this time of year all you need to do is shorten the long, whippy growths that the plant produced this summer, cu ing them back to leaves. In January or February you shorten these growths even further, back to two or three buds. The aim is to build up stumpy ‘spurs’ that will bear ﬂowers on a permanent framework of branches and control too much lush growth, so when you do get ﬂowers you’ll be able to see them. Young or newly planted wisterias shouldn’t need pruning. Just tie its new stems in to a framework to create next year’s display.

Sow nigella seeds in the soil

Get ready to sow a new lawn Autumn is the best time of year to start a new lawn from seed. Start preparing the soil where the lawn is to go now. First, you’ll need to dig it over and remove every scrap of perennial weed you find, including their roots. After digging, the soil will need two or three weeks to se le, or you risk ending up with a lumpy, bumpy lawn where areas of soil have sunk. Once it has se led, prepare the surface for sowing. Do a ‘penguin’ shuffle with your weight on your heels across the surface to firm and consolidate the soil and provide an even surface for sowing. Repeat at right angles to the direction of your first shuffle. Next rake over the surface to break the soil into a fine tilth. Again, do this in both directions to make extra sure that your lawn is level. When it comes to sowing, try to choose a day when you know showery weather is forecast, to save you having to water too much. Use string or canes to split the area up into squares a metre across . Evenly sca er the seed, following the rate advised per square metre on the packet, across each square. Rake to make sure the seed is in contact with the soil, water and wait for germination. You may want to cover the area with fleece to protect the seed from birds.

Remove weeds from the soil and rake it over to remove stones and hard clods of soil

Sprinkle seed evenly along the row – this reduces the need to thin out clusters of seedlings later

Former head gardener, TV and radio broadcaster and RHS judge

Martin Fish The undercover

GARDENER Martin evaluates his undercover tomato-growing techniques ACK IN SPRING I started to grow some tomato plants on a straw bale in my polytunnel. It’s a method that was used by commercial growers in the 1960s, before growbags came along. I haven’t tried it for years, and thought I’d resurrect it this season. The bale was thoroughly watered and fertilised with high nitrogen fertiliser, which made the straw heat up and start decomposing. Two weeks later, when the temperature inside the straw bale had dropped, I planted three tomatoes on the top in a ridge of compost and two trailing tomatoes to cascade down the sides. Overall, the upright plants in the bale have grown well and are carrying a reasonable crop of fruit, which is now ripening. The two trailing plants haven’t done as well. They made masses of long growth, but haven’t developed much fruit. The trailing variety is called ‘Firecracker’, which I’m also growing in hanging baskets, where they are producing a good crop of striped fruits. As my basket plants are fine, I can only put the long, leggy growth down to the fact that the upright tomatoes are casting too much shade for the trailing plants to grow well. I’m trimming back some of the excessive growth to expose the small fruits and flower trusses and I’ll up the high-potash feed in the

Sh hope that it will help the fruits develop. Back to the upright plants. I wouldn’t say they have done any better than those growing in the tunnel border or the ones that are in pots in the greenhouse, but they are fine and have been easy to look after. The benefit I’ve noticed in growing this way is when it comes to watering. Once the bale is wet it retains moisture for a few days, so it is possible to leave the plants and go away for a weekend without worrying about the plants drying out, whereas those growing in large pots need daily watering. Likewise, the plants in the soil border can also be left for a few days without watering.

Secure and prune grapevines As my grapevine continues to grow, I’ve tied the main lead shoot to a wire running the full length of my greenhouse and cut the sideshoots back by two-thirds.

Tidy streptocarpus I’ve given my streptocarpus plants a good tidy up, trimming off damaged foliage and old flowering stalks, and followed up with a feed to encourage a late flush of flowers.

OMINATIONS ARE BEING sought for a tree in England to wow judges in a Europe-wide search for the ultimate specimen. Charity Woodland Trust (WT) is asking the public to propose England’s ‘Tree of the Year’ to represent the country in the European competition next spring. However, in a situation reminiscent of the Eurovision Song Contest, neither England, nor Britain, has made the shortlist since the competition started in 2011. Romania won in 2011 and 2012 via two lime trees, while a plane tree from Hungary scooped top prize in 2013. Will it be ‘nul points’ again for the UK in 2014? “I have personally seen many of

Concern at Prince’s centre closure

Langtree

Festival site in funding hope GARDENS IN A 1980s festival site could be restored via a financial windfall. The boost came from a £1 billion government scheme to develop or accelerate the provision of more than 200,000 new homes in the country. The 40ha (100 acre) riverside site of the Liverpool Garden festival was chosen from a shortlist of 36 key housing schemes around the country. Developer Langtree proposes turning the 1984 festival site into a thriving housing and

leisure community with 1,300 new homes. Proposals include a new public park and restoration of the 11ha (27 acre) Oriental gardens to their former glory. The first of four International Garden Festivals was held in Liverpool between May and October 1984, attracting 3.8 million visitors. Although some of the site was used to create new housing, much remained derelict until 2011, when a £3.7 million facelift took place that included the Oriental garden.

IMMINENT CLOSURE OF a garden centre run by The Prince’s Trust (TPT) has caused Centre will still outrage in close this week the local community. The 386sq.m (4,157sq.ft) Fulham Palace Garden Centre is to close on August 31 and was potentially going to become a Pets at Home store, but the retailer decided against the move. Pressure was sparked by a 2,000 signature e-petition, condemnation from both rival and local businesses and reported accusations of a potential ‘conflict of interest’ in any deal with the retailer likely to secure lease of the site. The Prince’s Trust is selling the lease ‘to raise funds to invest in support for more young people’. Started in 1985 by young persons charity Fairbridge, the centre has grown and developed to compete with local businesses, including a major refurbishment in 2010. In 2011, the Prince’s Trust took over from Fairbridge and last year succeeded in purchasing twothirds of the site lease for £500,000. The Prince’s Trust Chief Financial Officer Amy Sterling is also an independent non-executive director of Pets at Home. The Prince’s Trust said the matter was being handled properly, ‘through an independent surveying company, in line with charity law’ and ‘would work with any future tenants to reflect the character of the local surroundings’.

Enormous branches of the muchloved black pine Pinus nigra in Oxford Botanic Gardens started to crack in late July while a musical picnic took place beneath.

Tidy parks plan could result in tax rebates

Volunteer cleanersÕ rebate Volunteers who help clean and maintain green spaces should be given a council tax rebate, a thinktank has suggested. Policy Exchange, a group close to government, made the suggestion in a raft of proposals to encourage people to make more use of parks facilities, against a backdrop of warnings that Britain’s parks are close to crisis because of spending cuts. They estimate rebates could be as much as £1,500 a year – the average amount of council tax paid by homeowners. Councils would set and manage the amount of time people would volunteer to get the rebate. The body also suggest a vote on whether to levy a charge for homes closest to green space, to help fund its maintenance. The charge would be on top of council tax, with those unable to pay exempt. The system is already being trialed in parts of London. • Visit: www.policyexchange.org.uk
