Garden lore: don’t do this at home

img_3822Well lookee here. When I was submitting three new articles a week to the Waikato Times – that was in the days before syndicated features and the resulting copy that became the newspaper equivalent of elevator muzak – I used to be on constant alert for subject matter. Old habits die hard and I reached for my camera to bring you this example of what not to do, photographed on a street in Auckland’s upmarket Mount Eden.

Don’t. Just don’t do this at home. The homeowner is disposing of lawn clippings by building a small grass mountain around the street tree on the road verge outside. It is not good for the tree and may even kill it over time. Building that mound can cause a condition called ‘collar rot’ – opening up the tree to fungi that attack the bark around the base of the tree. Bark needs to breathe, not be suffocated. Grass heaps also heat up as they start to decompose and that heat is bad for the tree, potentially killing the bark. Then the grass compacts down to an anaerobic sludge which can suffocate the surface roots. All this just so the homeowner doesn’t have to put their grass clippings out in the green waste or to find ways to compost it on his or her own property? Tidiness is not everything in the world of gardening and nature.

The story of Theo’s ‘nake

img_3742

I was cleaning the dead wood and needles out of Pinus sylvestris ‘Beuvronensis’ and decided that Theo’s ‘nake could be moved to the back shed instead of lying coiled, menacingly, within this tree as it has for maybe two decades. It is still in very good condition, this rubber snake. I say “coiled menacingly” because it looks remarkably realistic as long as one doesn’t inspect too closely and spot the lichen encrustations.

Overseas readers may not be aware that we are one of few locations in the world without snakes. Not even in zoos do we have snakes, so keen are we to preserve our snake-free status. As a result, we probably have more of a morbid interest and fear of snakes than most people and it amused us over the years to have this rubber specimen discreetly perched in the branches, though not without a recoil and a shudder. I have never forgotten reading ‘The Poisonwood Bible’ by Barbara Kingsolver with the green tree snakes which, from memory, killed one of the children of the obsessed missionary to the Congo.  In my mind’s eye, Theo’s ‘nake is intertwined with those fearsome creatures.

Why is it Theo’s ‘nake? When our children were young, Mark used to combine speaking engagements with family holiday trips. I had a rule that the children were only to be subjected to one garden, nursery or plant shop a day. At most. While interesting for us, such places are not necessarily riveting for young children. But California Garden Centre in Wellington in the early 1990s was a hit. Back then, its founder, Keith Lowe, was still actively involved. Keith is well known in the garden centre scene of New Zealand and in bonsai circles and I am sure that anybody who has met him will nod in agreement when I say he is one of life’s special people. He was the first mainstream retailer to turn up to visit when Mark was starting to expand the nursery from its mailorder origins to wholesale and he remained one of our most loyal customers. Not only did he take an interest in us, that extended to our children. When we visited his garden centre – I think it was the first to move into having an expansive gift shop alongside – he was extremely generous. So generous in fact, that I had to quietly ask Theo, our youngest and still a pre-schooler, to stop admiring anything because Keith insisted on giving him any object of admiration.

img_3739That is how the snake entered our family. Theo admired it. He was still too little to pronounce his s’ss (or should that be esses, or maybe ‘isses?) and he always referred to it as “my ‘nake”. He had a great deal of fun with it for several years. Yes, you can harass New Zealand cats with fake snakes and even adults instinctively flinch when a snake’s head looms close. When he grew out of it, we relocated it to the Pinus ‘Beuvronensis’. I think it may be time to move it to the back shed and produce it with a flourish should our son, now in his late twenties, ever have offspring.

It may be our recent trip to Canberra (snake territory… shudder) that made me more squeamish than usual about a rubber snake. There was also a news item last week that California Garden Centre has been sold – to none other than film-maker Peter Jackson. I think it unlikely that Jackson intends to continue running it as a garden centre but none of our family will forget Keith Lowe.

Postscript: I mentioned cleaning out the debris from Pinus sylvestris ‘Beuvronensis’. We have assorted aged, dwarf conifers and I try and do a clean-up once a year. They look a great deal better if I dislodge all the debris that catches within their tight branch formations and I like to think it keeps them in better health.

Plant collector: Schizophragma hydrangeoides pink and white

schizo-1Yes, Schizophragma hydrangeoides  looks like a climbing hydrangea but it is not the common climber which is Hydrangea petiolaris. This one comes from Japan and we prefer it to the usual form despite its difficult name. It is a close relative and a member of the same family but one step further back on the plant hierarchy from species to genus to family. Planted side by side, the schizophragma (pronounced skitsofragma or shyzofragma, whichever you prefer) is more floriferous and has significantly larger flower heads which seem to dance on the vine. This may be because its larger, winged petals (technically bracts, not petals) are held singly whereas H. petiolaris has its smaller bracts grouped in four, like a little flower all on its own.  The schizophrama is self-clinging and relatively slow growing so it doesn’t take over and swamp neighbouring plants. It needs something to climb up, however. If left to ramble at ground level, it doesn’t seem to flower though it does layer its way along so you can get more plants from it by this strategy.

img_6642The pink form is even more unusual. This fact was often not appreciated in the days when we used to sell plants. I recall too many customers who were at best ABP – Anything But Pink, at worst IOBW – I Only Buy White (flowers). Such self-imposed rules can certainly limit appreciation.

Schizophragma are hardy and deciduous so, to all intents and purposes, they fill an identical niche to H. petiolaris. However, petiolaris seems to perform better overseas where it is more floriferous and even gives autumn colour. Talking to our friend and colleague, hydrangea expert Glyn Church, we agreed that it is likely that petiolaris prefers a colder winter than we have, whereas the schizophragmas are perfectly happy in our conditions. As with lacecap hydrangeas, the winged ‘petals’ or bracts are the showy part whereas the proper flowers are the small, less spectacular bits behind the bracts.

We’d rather drink the gin than spray it on weeds, thanks.

Not an expensive brand and bought duty-free but we would still rather drink it than spray it on weeds

Christmas dinner conversation covered many topics but I wanted to test something I had read on the biochemist and the synthetic organic chemist at the table. The location was Canberra where we ate outdoors on a balmy evening and the temperature was still hovering in the late 20s Celsius as the night drew in.

Before leaving home, I had read the following passage in a new publication:

“You’re not trying to get your weeds drunk but the alcohol in cheap gin stops them in their tracks. Grab a bottle of spirits, mix with the juice of 2 lemons and spray on weeds.”

Discretion is the better part of valour so I won’t name the source of this advice but, as a gin drinker, it raised many questions. Where can I buy this cheap gin that is referenced? I wondered if it meant the diluted, flavoured gins that I see for about $15 at the bottle store but the Australian contingent tells me these are a New Zealand product and this advice seems more international, so maybe not. Why gin? Is it the juniper berries that are the magic ingredient or will any strong alcohol work as well? Is it really meant to be applied undiluted because around $30 to $35 for a litre of weed spray is extraordinarily expensive? What does the lemon juice do?

img_3601The biochemist and the synthetic organic chemist were more amused than anything else. They could not see any reason why gin should be more efficacious than any other form of alcohol. But none of us really wanted to sacrifice the Christmas gin to carry out field trials. Mark recalled the routine use of kerosene for weed control on carrots in his father’s day. When we arrived home, he found me the reference in the McPherson book, “Vegetable Growing in New Zealand”. It is so old, it doesn’t even have a date on it but the publisher was Whitcombe and Tombs Limited and it is a few decades or more since I have seen that name.

In case you want to know more about kerosene as a weed spray, it is advised to use it at full strength (!) through a high pressure nozzle at a rate of 40-50 gallons of spray per acre. Now you know.

Back to the matter of the gin. Given the lack of field trials, I turned to the internet. There were plenty of sites advising the use of gin as a “natural” weedkiller though none I found particularly credible. I admit there are limits to my interest in this topic so I cannot claim to have done exhaustive research. But I did ascertain the following:

  • It does not have to be gin. It is the alcohol that works – isopropyl alcohol (also referred to as rubbing alcohol) is likely to be the cheapest source of the active raw ingredient.
  • The addition of lemon juice is for the desiccating (drying) effect.
  • It is usual to dilute it quite heavily with water.
  • Liquid detergent is often added as a surfactant (spreader and sticker).
  • Vinegar (acetic acid) is the most popular base ingredient and appears to act in a similar manner to alcohol.
  • The increasingly widespread advice to use salt is a problem in that it will contaminate your soils.

One of the better sites I came across was The Garden Counselor. I particularly liked the comment: “I am not opposed to using vinegar as a weed killer, only the cavalier promotion of the idea.” Substitute the word “gin” for “vinegar” in that quote and it pretty much sums up what I think.

If you want to be purist and shun liquid detergents – also referred to as ‘dish soap’ in American parlance – in your homemade spray, you may like to check the ingredients of your pure soap substitute. I was shocked, I tell you, genuinely shocked when I checked the ingredients of many soaps recently. Even expensive, luxury soaps usually contain sodium palmate as the main ingredient. That is palm oil. Think of the orangutans and the issues regarding palm oil production. I am not sure about the justification of “from sustainable plantations” either. It seems to me that this just means the land has already been clear felled for monoculture. It is so hard being an ethical consumer these days.

As far as we are concerned, the bottom line is that if you want to avoid manufactured chemical weed sprays, hand weeding or boiling water are the best alternative eco-options. Also, there is still a desperate need for sound, well-researched and tested advice on organic gardening.

We drank the gin with lime and soda instead.

When joy is not too strong word

This morning my heart sang at the simple beauty down by our stream. The park is full of flowering trees and shrubs but never have I seen it look it as pretty as it did on this quiet Sunday morning.

Looking towards the stone bridge – Higo iris, primulas and white foxglove.

Weeds? Not to us any more. We prefer to talk about a meadow.

The Higo irises are the mainstay of the flowering this month.

Finally, the Wollemi pine was an amazingly generous gift from friends whose own circumstances had changed, meaning they could not guarantee its future. It has a special place in the park in a location where we hope it can grow to maturity and become one of the feature trees into future generations.

The act of gardening in itself is not often a joy – though it can be a pleasant activity and many of us enjoy the doing as well as the looking. Sometimes, when it all comes together, the experience of just walking through and seeing the meeting of human effort with nature is truly a joy and a delight.
