The days are shortening and an autumnal chill descends when the sun goes down, but September remains a time of new beginnings, new opportunities. It’s the beginning of a new academic year, the first day of term. And in the garden it’s arguably the start of the gardening year when you plant bulbs and biennials in preparation for a well-stocked flower garden next year and salad leaves and herbs for a spring harvest. Both elements coincided for me on 7 September. I was staying in South Somerset with my niece and her young family. I usually drive home from these precious weekends on Sunday but this time I stayed until Monday to see my middle great nephew on his first day at school and, on the way home, to visit a very special market garden 12 mile away.
Posing with his big brother for photographs, this usually mischievous small person looked very smart in his school uniform and very happy to finally join his brother at school. Subsequent reports confirm he has taken this major life change entirely in his stride. Early that afternoon I headed for the village of Alhampton, near Castle Cary, and Homeacres, the garden where Charles Dowding grows vegetables by pursuing his famous No Dig method.
I joined four garden writers* and photographers for a tour of the garden and introduction to the No Dig system. We were warmly welcomed by Charles and his wife Stephanie Hafferty, herself a gardener and writer AND cook. The productive part of Homeacres is surprisingly compact- a quarter of an acre with every inch utilised, long beds stretching away from the house, closely planted with crops, red frisée leaves contrasting with another chicory, this a vivid green.
The overall effect is of order, tidiness and plenty. Charles explained that by removing the lower leaves of, for example, Kale he discourages slugs and neaten its appearance. The fiery coloured flowers edging the beds as companion planting to attract pollinators and deflect less welcome insects throw the subtler greens, dark reds and purples of the beds into sharp relief. I saw orange marigolds, magenta flowering flax (Linum grandiflora), bright pink zinnias and now finished, but still displaying its double decker seedheads, bergamot (Monarda didyma). Charles tells us that a lemon sunflower (Helianthus annua) is grown for picking for the house.
Underlying this vision of plenty are years of layers of mulch atop a long dissolved away layer of cardboard. When he established Homeacres in 2004, Charles suppressed perennial weeds like couch grass and bindweed with cardboard before applying a deep (7 to 15cm) of organic matter: well-rotted manure, garden compost and municipal compost. He then planted into the compost. Now 3 to 5 cm of mulch is added to every bed in early winter.
I heard Charles Dowding speak at a KMIS (Kew Mutual Improvement Society) lecture a few years ago and was struck then by his infectious enthusiasm for his subject. He extols its simplicity: no effortful double digging when establishing a new vegetable plot and reduced weeding. But the principal benefit is its protection of the soil. Digging, whether manually or by rotavation, damages the mycorrhizal fungi so essential for establishing a healthy relationship between plant and soil. It is no coincidence that one of the chapters, or lessons, in Charles’s new book ‘No Dig Gardening: From Weeds to Vegetables quickly and easily’ is devoted to understanding soil and throughout the book he emphasises the importance of maintaining the integrity of the soil structure and encouraging its helpful micro-organisms to thrive.
The proof of the No Dig effect is demonstrated in two raised beds near the house, established 13 years ago. The right-hand bed was prepared and is maintained using traditional cultivation methods, that on the left is No Dig. Both beds are planted with the same crops in the same positions. In 11 years out of 13, the No Dig bed has produced a higher yield. The 1.5m x 5m beds in the garden produce 70kg of vegetables and Homeacres supplies salad leaves to shops and restaurants in the nearby town of Bruton.
The engine room for these abundant harvests is the long wooden roofed compost complex at the heart of the garden. Several compost bays fronted by removable slatted panels contain green waste from the garden (including the kale leaves mentioned above) as well as the municipal waste which is kept to ferment for a further 4 to 6 months before use). Compost thermometers can be seen inserted between the slats with the temperatures recorded and dates of turning carefully noted on the adjoining wooden pillars. On the day of my visit (cool and rainy) one bay registered a temperature of 70 degrees Fahrenheit despite its contents of green waste and carbon materials having been deposited only the day before. That new bay will be full of a rich, fertile compost 6 to 12 months from now. Knowing that the compost will reach very high temperatures during the rotting down process, Charles has no qualms about including blighted tomatoes and bindweed in the green element of the compost content.
A polytunnel installed by First Tunnels contains ranks of expertly cordoned tomatoes, lower leaves removed to both improve appearance and encourage the plants to photosynthesise at their apexes. On 10 August each year, the tops of the tomatoes are pinched off and now watering is being reduced to encourage ripening. The tomato beds are underplanted with French marigolds (Tagetes patula) and the side beds of the polytunnel are full of various types of basil.
In one corner of the polytunnel Charles showed us a fine watermelon vine and we were invited to taste a slice of ripe white-fleshed melon which was both fragrant and very juicy. We had already sampled a sweetly sharp baby plum tomato, a variety called Rosada, which because it is no longer available from seed merchants, Charles propagates from cuttings. We also experienced a couple of other unfamiliar flavours. As we progressed around the garden, we tasted a raw Edamame bean and the shield shaped leaf of buckler or French sorrel (Rumex scutatus). One of our party commented that this tasted like salt and vinegar crisps. And the tasting didn’t end there, as we were sent home with a generous bag of No Dig salad leaves- crunchy frisée and tender oak-leaved lettuce included.
Charles’s latest book (see above) is based on the first of his two online courses and explains the time-saving simplicity of the No Dig system. There is a quiz at the end of each chapter with answers at the back of the book. The book covers planning the layout of a vegetable plot, creating and maintaining paths and making compost. There is also a chapter devoted to identifying weeds with excellent photographs.
I drove away from Homeacres wishing that I was higher up the waiting list for a local allotment (I’m 3 years into a 5 year wait!) but determined that when the time comes I shall employ the No Dig method. In the meantime my keen gardener niece is keen to start a new vegetable plot to add to the existing two plots in her garden and I have already tasked her with saving cardboard to start it off.
