Garden maintenance, sustainability or just garden grooming?

Judge not a garden upon the daisies in its lawn

Judge not a garden upon the daisies in its lawn

There is nothing like preparing a presentation to focus the thinking. So most of our discussions here recently have been clarifying thoughts on what makes a good garden. The ever-so-brief outline is that good gardening is a combination of good design, good plants and plantsmanship over time, maintenance and sustainability all served up with more than a dash of panache, style or flair. If you want the full details along with all the accompanying examples, you will just have to come to the Waikato Home and Garden Show today at 12.30 or tomorrow at 2.30 (find the Weekend Gardener Stage).

Because we garden on a large scale here and The Significant Other had a deeply disturbing Significant Milestone Birthday recently (“It is all downhill from here,” he keeps reminding me), sustainability is a gardening principle we are spending a lot of time thinking about. But it wasn’t until I was working through my presentation that I came up with the hypothesis:
“We spend far too much time worrying about garden maintenance in this country and not enough time worrying about sustainability. In fact, so-called maintenance is in danger of being accorded a status way beyond its importance. What compounds this is that what is frequently seen as garden maintenance is in fact garden grooming – edges, hedges and lawns.”

Garden grooming is what presents a garden well and it is just as important as housekeeping indoors. But while the initial design and fit out of a house is a highly skilled exercise, often employing the services of an architect and an interior designer, the routine cleaning is a low skilled task at best and can be carried out perfectly adequately by someone with little thought and no understanding of the skill level that went into creating the interior. So too in the garden. When we still employed staff in the nursery, we would despatch them into the garden with leaf rakes and edging tools when we had to spruce up in a hurry. Generally they weren’t gardeners and they needed clear boundaries set lest they do real damage, but they were fantastic garden groomers. They could whip through and titivate in next to no time, partly because they didn’t get distracted by plants. At the end of it, the garden looked fantastic. It was a bit of a revelation to us that if the underpinning garden is in good shape, it doesn’t take particular skill to add the icing to the cake. Yet it is that sharp finish that is often judged as garden maintenance.

People who open their garden to the public will know all about this final grooming round and just how smart it makes the garden look. Most garden visitors now expect that high level of finish, especially for festivals and events. It is a great deal easier to manage if your patch is a small town garden and I have seen some splendid examples of immaculate presentation. Alas, as many have come to consider that this elevated level of garden grooming is the measure by which a good garden is judged, large gardens encompassing several acres have come under pressure to achieve the same, immaculate, sharp appearance. We do it here once a year for our annual garden festival and I love how smart the garden looks and vow every year to maintain it at that level. But it is completely unsustainable across seven acres. Without an army of gardeners (about one to an acre, perhaps), it just is not possible to keep it that spic and span for 52 weeks of the year. Besides, battling nature takes all the fun out of gardening.

I call that finish garden grooming. Garden maintenance should be considerably more extensive and require much greater skills. It is, or should be, all about managing your garden in sustainable ways so that it is a source of pleasure and not a burden. It is about keeping control of weeds so they never get beyond you, about keeping plants and soils healthy and about eliminating gardening practices which are all round bad for the environment. It is about adapting to changing environments within the garden over time. As trees and shrubs grow, they start to cast shade and their roots spread further. The gardener needs to change some plantings and practices as the growing environment changes. Maintenance is about keeping trees a good shape, avoiding forked trunks, lifting and limbing, and about knowing how and when to prune. It is about lifting and dividing choked perennials, deciding which plants are precious and which are expendable, restricting or eliminating plant thugs, rescuing bulbs which have become so overcrowded they no longer flower.

That is what garden maintenance should be about. To me, it is not about whether there is the odd flat weed in the lawn. Goodness knows, we have a park full of pretty white daisies though we do try and keep flat weeds out of the house lawns. At least our lawn clippings are not toxic and can safely be put on the compost heap or indeed used in the vegetable garden except that we never gather the clippings. We mulch them back in and that means we never have to add fertiliser to the lawn.

I appreciate the immaculate presentation of a garden but only when it is the final touch to one which is actively and positively gardened, not when it substitutes for an underlying lack of quality management. Look beyond edges, hedges and lawns.

Grow It Yourself: Potatoes

The history of the potato is a remarkable one and surely warrants further exploration at a later date. But is it worth growing at home? If one potato is much the same as the next to you, then probably not, because they are so cheap to buy. But if you love your taties and can tell the difference between varieties, then of course you will be growing them. And the message from the Head Vegetable Grower here is that if you want new potatoes for Christmas dinner, you will have to get them in this very weekend because most early varieties take from 75 to 90 days to mature, though Swift and Rocket can do it in 60 days. Potatoes are vulnerable to disease so it pays to start with fresh certified seed potato from garden centres each year rather than using your own old potatoes which are shooting.

Potatoes are heavy on space. Because this is not a problem for us, we do them in rows digging narrow trenches about 20m deep and wide (full sun, well cultivated friable soil, fresh ground if possible), piling the soil to the side of the trench. The potatoes are then laid on the bottom of the trench and covered with 10cm of compost. As the shoots reach about 20cm, more soil is layered on top – a process called mounding. The potatoes form on the stems so you need to encourage stem growth and keep a thick enough layer of dirt to keep the potatoes well covered and stop them going green. The mounding process continues until the plants have flowered and it may be necessary to water in dry spells because the mounds lose moisture.

In smaller spaces, the stack of tyres is a popular technique, though hardly aesthetic. Potatoes need good drainage so it is better to build your stack on dirt rather than concrete. Start with one tyre and fill with good soil or compost, making sure you fill the rims as well. Plant about three potatoes and, as mounding is needed, add another tyre and fill with soil. You will probably end up with a stack of 3 or 4. If you plan to use potting mix instead of soil, they will become expensive potatoes.

One of the reasons for getting potatoes in now is to try and get crops through before the dreaded blights hit. In our experience, if you are not willing to spray your potatoes regularly with copper (about every fortnight), unless you know what you are doing, get your crop in early and manage them very well, you will get disease. Don’t use nitrogen based fertilisers as they are a root crop. Favourite early varieties here are Liseta and Jersey Benne, for main crop Red Rascal and Agria.

I suggested to Mark that the start of a new year here was marked by the magnolias and early spring but he was pretty adamant that it is the snowdrops that herald the new beginning. The snowdrops have long finished, most of the narcissi are passing over and while the magnolia season continues, it is on the wane – the opening of Serene heralds the end of the season because it is the last of the major ones to flower for us. But temperatures are rising, the rhododendrons are opening and other new plants open every day. The trilliums are a triumph for us here. We are not natural trillium territory (bar two days this winter, we lack the winter chill they prefer) and have to choose planting situations carefully.

Each flower may be only three petals but when you get the deep red ones blooming with the light passing through, the effort is well worth it. The erythroniums are in full flower. If we don’t get torrential rain, we may get two or even three weeks of pleasure from these short-lived, dainty delights. The countdown to our annual garden festival at the end of October is on so the pressure is mounting.

In a rash moment, I agreed to present at the Waikato Home and Garden Show next Friday and Saturday. My main presentation is entitled “What Makes a Good Garden” (Friday at 12.30 and Saturday at 2.30) and I am also doing a presentation on our annual festival (styled the Powerco Taranaki Garden Spectacular this year but we will say no more about that, formerly known as the Taranaki Rhododendron and Garden Festival) at 6.30 on Friday and 4.30 on Saturday.

Plant Collector: Magnolia Athene

Magnolia Athene in her glory

Magnolia Athene in her glory


Thank goodness for the mid season magnolias this year. There we were, as usual, admiring the early season ones in flower when a once in a hundred year event hit here – snow followed by a killer frost in late August. The early bloomers did not like it one bit. But the next flush rose to the challenge and their flowering was unaffected. This one is Magnolia Athene, a particularly lovely variety with big ivory white flowers sporting a violet pink base. It is what is called a cup and saucer form. When open, the outer layer of petals drops a little to form the saucer, while the inner petals keep a tight cup form. Botanically, magnolias don’t actually have much in the way of petals, they have tepals which look like petals but that tends to confuse all but the most enthusiastic gardener.

Bred in the early 1960s, Athene is one of a small series from the late Felix Jury in his quest for new plants which would carry the good aspects of the classic campbellii magnolias but flower on young plants and not grow as large. It should flower within a year of planting out. The parents are magnolias lennei alba (which is a very tidy, smaller tree with pure cream flowers) and Mark Jury (which is a large growing tree with very large, heavy textured flowers in lilac tones). Athene was a significant advance on the parents and puts on a magnificent display with its bi-coloured blooms. It will eventually reach about 5 metres with an upright habit and the flowers are pleasantly scented.

New Zealand’s Native Trees by John Dawson and Rob Lucas

New Zealand's Native TreesWhen one reviews books, there is a fair amount of dross to wade through to find the gems but only occasionally does a definitive benchmark study turn up. New Zealand’s Native Trees is a huge book (570 pages and 2300 photographs) and comprehensive, covering 320 different species of trees, including sub species and varieties – which is all of our trees, I understand. We don’t always realise in this country just how special and unique is our native flora and this book covers pretty much everything you will ever need or want to know. It is not an off-putting academic treatise, though it is a reference book (it is too large to be anything else – you need to rest it on a desk) but with accessible information. Trees are photographed in situ as well as with comprehensive close-ups to aid identification. The text is clear and able to be understood easily by anyone ranging from those with a desultory interest through to the enthusiast and the expert. Additional information of interest is contained in boxes – the cabbage tree moth which chews holes in cordyline foliage, how to tell kanuka from manuka and much more.

The lead author is Dr John Dawson, now retired Associate Professor from the Botany Department of Victoria University while the photographer is Rob Lucas, a retired horticultural lecturer from the Open Polytechnic. The book represents seven years of dedicated work. Publisher, Craig Potton, is renowned for producing handsome, high quality publications and the production values of this book are top quality which is entirely appropriate, given that it is a timeless book which will justify its place on every bookshelf for many years to come. How refreshing it is to see an NZ publisher who is not scared to bring out a tome of enduring quality about plants. All credit to the editor, Jane Connor.
