Garden lore

” The nonagenarian President of Magdalen, Dr Routh, was once brought the news that the acacia tree outside his lodgings had been blown down by a storm. “Put it up again,” was all he said; and up, of course, it went.”

Oxford by James Morris (1965)

Summer pruning

Now, at the height of summer, is the time to prune prunus, be they flowering cherries, fruiting cherries, plums, peaches, nectarines, apricots or almonds. Naturally you wait until they have finished fruiting for the season where possible. These plants are always pruned when in full growth to stop the dreaded silver leaf or silver blight getting in to the cut surfaces and taking hold. If your flowering cherry had large patches which didn’t bloom in spring and where the leafy growth is denser, then you have witches’ broom and it needs to be cut out now. If you leave it be, it will take over the whole tree and you won’t get any flowers at all in due course. It affects the Japanese type cherries but not the earlier flowering campanulata or Taiwanese varieties.

Make clean cuts with a sharp pruning saw and if you are moving on from an unhealthy tree specimen, then disinfect pruning implements between. Otherwise you can transfer disease. Wiping the cutting blades with meths or chlorine should work.

Cicely’s gardens

My mother and sister at the start of another of her gardens

I have been thinking of my late mother, Cicely Denz, this week and realised I have never paid tribute to the fact that I, as well as Mark, grew up in lovely gardens. The difference is the plural – Mark grew up in the one garden that is now our home at Tikorangi. I grew up in multiple gardens, mostly around Dunedin.

She was a fine garden maker, my mother, though the gardens were distinctly clonal. She worked from the same plant list of favourites and she never stuck around long enough to see them mature. I am sure it would have been different had my father lived longer and she had her lifelong love next to her in body and not just memory. She would have put down roots and may well have earned a place in the modern garden history of this country.

Instead for a woman of her generation, intelligent but under educated with no recognised career, lacking a man at her side when solo parents were almost unknown, leading a distinctly precarious financial existence and lacking the usual anchors in life, my mother turned her gardening into her public face and her claim to status.

She was always a gardener. Her first was an acre in size. When my father was demobbed post WW2, he went to work at Porton Down in Salisbury. As that place was a military scientific research facility, this may well have contributed to his premature demise (think nerve gas research, organophosphates and other agricultural chemicals). With the shortage of housing in bombed Britain, they relocated two military huts and my mother built her first garden around them. Despite extensive reading of the major English garden writers, she never deviated from the romantic English country cottage style of gardening of that era.

By the time I was born, my parents decided to return to New Zealand with the four children in search of the traditional NZ family life and employment opportunities meant Dunedin. That English style of gardening translated well to Dunedin which may never get as cold as most of the UK but has similarly low sunshine hours, never gets hot and is characterised by a soft light unknown to most of us north of there.

Every garden had Prunus Kanzan

Every garden had Prunus Kanzan

She was always renowned for her proper English primroses. They will grow here in more northerly climes but they hardly flower whereas my childhood was spent with vases of them in season. Along with violets, hellebores and London Pride. Roses were always of the old fashioned variety, not a vulgar hybrid tea in sight. And herbaceous paeonies, big clumps of these spring delights. We all grew up knowing the name of Paeonia mlokosewitschii – she was a demon for botanical names. Every garden had at least one Prunus Kanzan (in pink) and one Prunus Tai Haku (in white).

The paeony with the impossible name

The paeony with the impossible name

Lawnmowers were not her friend. She attempted to pressgang any passing young male into using the push mower on grass which tended to be overgrown. At one stage, she decided that a brand new motor mower might do the trick. This required site visits from the poor young salesman, whom she probably reduced to tears with her complete inability to start the engine and her tendency to blame the machine. The shop took the mower back.

In due course, Cicely gave up on all lawns. She figured that it cost money to maintain a lawn (it does) and she would rather have gravel paths and garden.

Not only did she not have lawns, there was a total lack of hard landscaping. Good gardener she may have been and certainly she had no fear of hard work, but she lacked any home handywoman skills and she rarely had sufficient money to pay for someone else to come and install anything like fencing or paving. Garden ornaments were completely absent. Mind you, this was in the days before it became fashionable to adorn your garden like an overstuffed display cabinet.

I quipped many years ago that all she needed to keep her happy were five plants, a spade and a wheelbarrow. She could then move the plants like chess, as she was wont to do. But she was a garden maker at heart. The joy for her lay in breaking in a piece of ground and planting it up, garnering much admiration from passersby and neighbours. She had little interest in maintaining the garden once established so soon became bored, finding some compelling reason to move. I kid you not. In my lifetime, I can recall about ten gardens she made. There may have been more.

Her mantra was ground cover. She firmly believed that if you plant ground cover densely, it suppresses the weeds. Well, no. She didn’t like weeding and ground cover plants mask the weed infestations, rather than suppressing them. It also makes weeding more difficult because the weeds and plants become deeply intertwined. Her style of gardening was hugely labour intensive and generally involved lifting all the ground cover perennials once a year and dividing them so the weeds did at least get dealt to annually. She spent pretty much every single day in her garden.

Cicely’s style of gardening was transient. These gardens lacked the bones to carry them through the decades. There was a lack of good long term trees and a lack of structure or form. I doubt that any survive now. She never went back to look. But for the few years of their glory, they were a delight and a fine example of that particular garden style.

Plant Collector: Cordyline stricta

Cordyline stricta - blue flowers but no scent

Cordyline stricta – blue flowers but no scent

Cordylines are commonly known as cabbage trees in this country. Some wit branded them as Torbay Palms for the UK market and we know that most of them are ours, native to New Zealand. Not this one, however. The blue flowers and the unchewed foliage are a hint – C. stricta belongs across the Tasman, native to coastal New South Wales through to southern Queensland. It is a native moth – Epiphryne verriculata – that chews our cordylines but it does not fancy the foreign varieties so C. stricta doesn’t get the moth eaten look.

It is an excellent garden plant, being tolerant of a wide range of conditions and relatively hardy. It will take coastal winds, even dry conditions, grows in sun or shade and is okay with light to moderate frosts. We have never had it reach much over 3m tall and it clumps so if it is getting unwieldy, it is easy to chop out the longest stems. The leaves are a little fleshier than the stringiness of our native varieties so it is more amenable with the lawnmower. Then there are the lovely blue flowers in summer. But it doesn’t have everything – there is no scent and that is one of the hallmarks of our native ones.

Garden lore

” There are some botanical names that are teasers. Where the Polish discoverers or Russian explorers come upon the scene the result is apt to be an appalling jungle of horrors. Michaux, Stribnry, Przewalsky, Tchihatchew are responsible for some real jawbreakers; and when it comes to Michauxia tchihatchewi, exhausted humanity gives up in despair.”

Just a few of my aged concrete pots - far too heavy to use with ease

Just a few of my aged concrete pots – far too heavy to use with ease

Making your own plant containers

I was looking at step by step instructions for DIY concrete pots in a NZ publication and have one word of advice: don’t. I inherited concrete pots from my in-laws, made in the days before mass produced ceramic pots became so cheap and widely available. They look aged and anonymous but over the years, I have found I use them less and less because they are just too heavy to be convenient. If you want that aged look, go back to hypertufa which has been used since 1930 to recreate a weathered stone look. There is plenty of information on the internet but the general recipe for hypertufa is 1 part cement to 3 parts aggregate (often a mix of perlite, peat moss or river sand). It is no more bother than making pots completely out of concrete but much lighter to handle.

Plant Collector: Hydrangea serrata “Preziosa”

Hydrangea "Preziosa" - generally colour stable in all soil conditions.

Hydrangea “Preziosa” – generally colour stable in all soil conditions.

In the world of summer flowering shrubs, hydrangeas are surely king. There are many others beyond the common macrophylla types and the serrata family from Japan and Korea are perhaps a little more refined. Certainly they are smaller growing and perfect for semi shaded positions. “Preziosa” is a hybrid but predominantly of serrata lineage. It is a smaller moptop – the pompom type of flowers. Two factors set it apart from many others. Its colouring is not affected by soil type and its flowers change colour as they age so you get a range of different colours on the one bush. They open green, changing through yellow tones to cream, fading to white with pink tinges on the petals, then deepening to pink shades and ending up dark cherry red. It also has attractive red stems and the foliage is often tinged red.

“Preziosa” is a not happy in full sun and it particularly dislikes hot, dry conditions. I moved these plants from an area where there was too much root competition from surrounding trees and they perked up enormously in well dug soil with plenty of compost added but still in open shade. They reach about 150cm in height and a metre wide, making them a good option for smaller, town gardens.
