DAVID PATCH Professional nurseryman, R V Roger Ltd
CURSEDWITH CANKER I am writing to you in desperation over a problem I have with parsnip canker. I follow a four-year rotation on my allotment and grow the variety ‘Gladiator F1’ which is supposed to be canker resistant. I am at a loss to know what to do to produce clean white roots with no large discoloured lesions, particularly on the shoulder. I sow the seed in April towards the end of the month to achieve better germination and thin out to 4-6in apart. I usually use blood, fish and bone incorporated into the soil about 10-14 days prior to sowing. Mr Hartill, Devon COLIN SAYS: Parsnip canker is a regular problem, although infections have lessened in recent years with advice from the seed companies on delaying sowings. I suggest the key sowing time is very late April to mid-May. Canker is much more of an issue in cold, wet soils from early sowings. Parsnips need nitrogen in the seedbed and ample phosphate and potash once well established. Blood, fish and bone types of general fertiliser should be fine. Parsnips do prefer light soils, sandy loams and certainly to be free of any sharp ★ stones to give a better shaped root and smoother skin. Canker (Itersonilia spp) can be linked with other fungal pathogens (phoma, rhizoctonia for example) to cause problems, usually showing on the shoulders as orangey brown to black lesions.

WHAT’S GONE WRONG? I am blessed with the most beautiful loam soil, which has a fairly high pH at 7.0, which coupled with being in a limestone area results in having limestone chippings in the soil which does not help with the pH. I make my own compost and dig in a six-inch depth of compost every winter and of late have added bagged sterilised farmyard manure also. I also use Growmore, blood, fish and bone or Maxicrop fertilisers. My garden soil grew very good vegetables for 15 years. But over the last three, the vegetables have reduced in quality. Now the leeks never grow thicker than a pencil, the runner beans never grow a glut, parsnips are very difficult and this year did not germinate at all. Also, this year my winter beetroot has not produced and my purple-topped turnips are only pea size. Broad beans grow but never many on a plant and potatoes never more than a few per root. Tim Hunt, Peterborough MIKE SAYS: You seem to have the ideal soil and pH for growing fruit and vegetables. Adding organic matter will build up and maintain the soil’s structure. All that is then required for plants to grow successfully are water,
warmth and nutrients. Top dress the entire plot each spring with a general fertiliser such as National Growmore or pelleted poultry manure if you are an organic gardener. Carry on adding the organic material. It will help to balance the pH as it breaks down in the soil. Don’t allow plants to become stressed. Use liquid seaweed feeds during dry periods. They will be taken up more quickly by the roots. The cocktail of fertilisers could have worked against you by locking up nutrients in the soil. Use crop rotations as part of your soil management. I think that your problem may be caused by the garden’s microclimate. In 2016 we suffered low temperatures for a long time and the soil was slow to warm up. Invest in a soil thermometer. The minimum soil temperature reading should be 8C (45F) recorded over seven consecutive days before commencing sowing or planting. www.kitchengarden.co.uk
Hanging gardens of plenty

It’s not only annual flowers that make perfect hanging basket displays – a basket laden with ready-to-pluck produce can be every bit as attractive, as gardening expert Ben Vanheems explains
www.kitchengarden.co.uk
business? Well, yes and no. You see an edible hanging basket can be every bit as attractive as an ornamental one. And what you lose in flowers, you make up for in leaf textures, colours and quirky character. Take a basket groaning with hundreds of treat-sized tomatoes, or a rustic wicker bowl crowded with luscious salad leaves suspended temptingly at eye-level. You’re getting a feast for the eyes and the belly! ➤

I
love a well-balanced hanging basket: one that’s bursting with floriferous exuberance. Hanging baskets, like any hanging or wall-mounted container, brighten our world. They lift spirits and add a welcome splash of colour to our lives. So why, then, would anyone bother to grow edibles in hanging baskets instead? Surely the best place for our crops is at ground level where they can quietly sit and mind their own

How many plants?
Suspended planters of produce offer yet another way to grow more. In our increasingly tiny suburban gardens, this is no bad thing. Dangling from porches, mounted on to walls or framing a balcony, hanging fruits, vegetables and herbs add a new level of growing that’s convenient to harvest, up and away from slugs, and that’s downright pretty to look at. Joining the humble hanging basket are all manner of upside-down, topsy-turvy planters, half-baskets, troughs and pots that, with a few screws or hooks, can be attached to walls and fences. Many hanging planters even include a built-in reservoir to take the strain out of watering. Then there are the many creative ways of recycling old containers into attractive hanging planters – some weird, some wonderful, and some both weird and wonderful! The most important thing to bear in mind when selecting hanging containers is the space and resources plants need to grow. Hanging baskets are more exposed to the sun and wind, so will dry out quicker than containers on the ground, so make sure baskets can offer plants what they need. Pick ones that are at least 35cm (14in) in diameter so the compost within has more of a buffer against the wicking/baking effects of wind and sun. As well as suspending baskets and planters around your house, shed and fences, you can also hang them from purpose-sold shepherd’s hooks, either free-standing or spiked into the ground. This can really maximise the growing space on patio gardens, while creating a Hanging Gardens of Babylon in miniature!
These guidelines are for a standard 35-40cm (14-16in) hanging basket. ■ Cherry tomato: 1-2 (plus French marigolds or basil as companion plants) ■ Strawberries: 3-4 ■ Peppers (smaller varieties): 2-3 ■ Chillies: 3-4 ■ Peas and beans: 6, plus salads on top ■ Leafy herbs: 4-5 ■ Cut-and-come-again salads: Broadcast sow very thinly, or 10cm (4in) apart ■ Spinach: 10cm (4in) apart
WHAT TO GROW
Some crops are tailor-made for growing this way. Cherry tomatoes such as ‘Tumbling Tom’, strawberries, leafy herbs, salad leaves and chillies are just a few of the many plants that, thanks to their relatively compact size, work well in hanging baskets and containers. How many you plant into each container will, of course, depend on its size. But always err on the generous side so that plants aren’t crammed in and competing for available moisture and nutrients. Naturally rambunctious crops such as strawberries or peppers are best grown on their own, while others lend themselves to a creative display that’s every bit as eye-catching as a basket of flowers. A herb display with mint, parsley, chives with creeping thyme spilling over the side, for example. Or a large basket planted up with French beans to the sides and a topping of cut-and-comeagain salad leaves, spinach or miniature beetroots.
A simple yet stunning solution for everyday salad leaves
Remember that there are plenty of edible flowers too. Trailing nasturtiums or cheery calendula will bring welcome colour as they provide flowers to add sparkle to your summer salads.
HOW TO PLANT UP
Hanging baskets and other hanging containers are planted up in much the same way as any other planter. Most multi-purpose compost as a growing medium is fine, so long as you’re on hand to water and feed plants regularly. Adding some leafmould to the compost can help to improve its water retention. You could also mix in slowrelease fertiliser granules to help sustain plants for the first part of the growing season, after which regular liquid feeding becomes a must. Hold round-bottomed hanging baskets steady by placing them on to buckets before beginning work. Wire-framed hanging baskets will need a
Vigorous crops such as peppers and strawberries are best planted alone

Steve Neil visits Ston Easton House in Somerset and is impressed with what’s growing in its kitchen garden and glasshouses
INSET: head gardener, Steve Hargreaves
S
tanding in the Saloon of Ston Easton House, looking through the old glass of the window at the cascaded waters created by Humphrey Repton, you wouldn’t think for one moment that you were in a hotel. You would think you were a guest of the family, invited to a country house weekend in Somerset. And of course Ston Easton was a house at one time, the family home of th he Rees-Mogg family. The past may be a foreign country where they do things differently, but here some things haven’t changed. Every country house always had its kitchen garden to provide it with fresh fruit and vegetables for the table, and in the last four years Ston Easton House has revived that tradition.
FRESH VEGETABLES
Steve Hargreaves, the head gardener, is responsible for the 36 acres of gardens that belong to the hotel. As well as the water features and the Repton landscape, there is also the kitchen garden with its glasshouses. “Four years ago when we took it over there was a fair amount oof work. We had to cut back brambles and taake several feet off hedges, but once we had done that we pretty much had a blank canvas,” he said. Today h tthings are looking good, with some imaginative modern planting in the borders and the shape of the original design clearly visible. I ask how many gardeners work there. “Two,” he said. “Me and Dale.” ➤

GET GROWING WHY CLIMBING BEANS?
For their delicious, nutritious pods produced in profusion and because they are great for freezing there is little waste. Also the upward growth gives them a small footprint on the plot, they are easy to grow, and have lovely flowers that are great to look at and welcoming for pollinators.
PREPARING THE GROUND
Beans do best in a sunny, sheltered spot, preferably south or west facing, and where they won’t shade other crops for too long each day – unless you want to use this to grow things such as leafy salads which might appreciate the cooling effect the shading provides. They like a fertile soil which is neutral to alkaline and for the best results the soil should be enriched with plenty of organic matter in the winter. Lime if necessary six weeks after adding manure to bring the pH (lime level) to around pH7.
See our reviews of some great bean frames at: www.youtube. com/watch?v= hhZDbq8wIWY
BUILD THEM STRONG
Strong trellis up a fence is an excellent alternative support for beans or train them over an arch or pergola
Plants are vigorous and heavy when in full crop so make sure your supports are strong enough to take the strain (see page 72 for an easy-to-make and attractive bean frame). If your DIY skills are lacking, then a simple wigwam of hazel or bamboo canes will do the job well, or take a look at the many excellent supports available from top suppliers on our advertisement pages.
COUNT ON BEANS TO…
Beans have nodes on their roots which act as a home for special bacteria. These fix nitrogen from the atmosphere which ultimately helps to feed the crop. Leaving the roots and therefore the nodules in the soil at the end of the season adds nitrogen for future veggies.
FOR SMALL PLOTS AND POTS? Yes, definitely. They can be grown in small spaces or large tubs (choose one which is 60cm (24in) in diameter or larger for climbers and grow up some bamboo canes). Alternatively, choose one of the dwarf runners such as ‘Jackpot Mixed’ or ‘Hestia’ for your patio pots, which need very little support at all.
A serving of 100g of green beans can, among other things, provide you with around 25% of your recommended daily amount of vitamins A and C and 12% of vitamin K. They also contain useful amounts of fibre and are a low fat, low GI food.

OUT & ABOUT
Gardening consultant and organic veg expert Sally Cunningham reports on an exciting project which captures the experien nce of growing exotic vegetables at three community gardens
T
hose of you who remembered the Sowing New Seeds project run by Garden Organic, which collected exotic crop plants grown across the Midlands a few years ago, might have wondered what happened next. Part of the project’s success was the addition to the Heritage Seed Library of successful new species of vegetables with cultural and ethnic heritage, which actually grew well in the UK because they were being grown by people here on allotments or in back gardens who knew about them and recognised which plants to save seed from. During the project both Anton Rosenfeld and I visited more than 80 allotment sites and community gardens. We discovered so many great stories from the people, about their lives and growing their crops, we thought these were as worthy of saving as their seeds... which led to the next project, Growing From Your Roots. ➤
