Lawns tell lies. The grass will almost certainly survive the current drought

Lawns tell lies. The grass will almost certainly survive the current drought

Surviving the drought
As the drought conditions bite deeper, keep to priorities for water use. Vegetables have the greatest need. Dry conditions can force plants to bolt to seed early (their instinct under stress is to survive by ensuring seed set) and in some cases the produce becomes bitter or woody. Water the soil, not the plant because it is the roots that achieve the best uptake. Watering in the evening reduces how much will evaporate immediately and when you are not watering the foliage, it won’t encourage diseases. If you overhead water by sprinklers, do it early in the morning to give the foliage time to dry.

Most of our common herbs are Mediterranean in origin so are well used to being dry in summer. Don’t waste time and water on them.

Lawns can survive a remarkably long time without water, despite their appearance telling lies. Annuals will bolt to seed early and perennials will pass over more quickly. Trees, shrubs and hedges should all be fine unless they were recently planted from mid spring onwards, in which case you may wish to give them a drink.

Do not mulch your garden now. It will slow down the absorption of water when good, steady rain arrives – which it will at some stage. Mulch can keep water out as well as keeping it in. Just take heed and get a good layer of mulch on at the right time next spring.

Garden lore

“ My garden is an honest place. Every tree and every vine are incapable of concealment, and tell after two or three months exactly what sort of treatment they have had.”

Journals by Ralph Waldo Emerson (published 1909-1913)

??????????????????????????????? The very hungry monarch caterpillars

There is something bravely optimistic in the sight of a diaspora of monarch caterpillars heading away from a swan plant they have totally stripped, in search of another food source. This is even more so if you know there are no more swan plants around and judging by online searches and discussions, the state of the monarchs’ food supplies at this time of the year is causing a great deal of angst.

Do not panic. Reach for slices of pumpkin instead. We have done it here in one crisis year with good success rates. The NZ monarch butterfly website (www.monarch.org.nz) tells me that you can also use cucumber and courgette. But these options are not a complete diet and are only suitable for caterpillars which are already half grown, or about 10 days old.

What we did was to confine the caterpillars to an extremely large carton (so they didn’t head off looking for swan plants) with plenty of twiggy sticks so they could pupate and hang as cocoons successfully. We replaced the sliced pumpkin every day or two. Being caterpillars, they feed constantly from one end and excrete from the other – their poos were an astonishing orange.

Plant Collector: Nerine filifolia

The daintiest of nerines - N. filifolia

The daintiest of nerines – N. filifolia

Nerines are a star of our autumn garden so the appearance of N.filifolia always arouses that slight sense of autumnal melancholy in me, coinciding as it does with the realisation that the days are getting shorter again. But the references tell me that in fact it is summer flowering and certainly it is always the first nerine to bloom here. It is also the daintiest member of that family that we have. It is tiny. While the stems can be about 25cm long, individual flowers are only a cm across at most with particularly frilly, waved petals in deep pink and nine flowers to each head.

The filifolia part of the name means fine foliage, grass-like in the vernacular. With us it is evergreen. In harder climates, it may lose its leaves. Like all nerines, it is a South African bulb, from the Eastern Cape area. It builds up easily and is not fussy in the garden, as long as it doesn’t get swamped by stronger growing plants.

Nobody could call it spectacular. It is just one of those little treasures that adds detail and seasonal interest to the garden. The problem will be sourcing bulbs. You will probably only find it from bulb specialists or other gardeners, though Trade Me is always worth watching for odd plants that are not widely available these days.

The Lost Gardens of Christchurch

Behind every overgrown gateway, there is a personal story

Behind every overgrown gateway, there is a personal story

I went to Christchurch last weekend.

It is very hard to grasp the sheer scale of what has happened in Christchurch when you don’t know the city well to start with and you are gaining most of your information from the mainstream media. That is not a criticism of the media. It is just that the biggest and most spectacular will get covered (such as the demolition of the CBD) or the most extreme (families still living in caravans or garages). In between lie tens of thousands of individual domestic stories of lives changed forever.

I stayed in an old part of the city, immediately beside a red zoned area alongside the Avon River and my evening strolls took me down streets which are to be cleared by July. The water level in the river has risen and these residential areas are deemed too high a risk to repair. It was poignant in the extreme.

Graffiti and vandalism abound

Graffiti and vandalism abound

Initially there was a slight thrill of mystery and the classic children’s novel “The Secret Garden” by Frances Hodgson Burnett kept coming to mind as I peered at overgrown gateways and glimpses of houses behind rampant foliage. These had been gardens tended down the years until the earthquakes. With no humans in residence any longer, the plants were taking over and there was a sense of wild abandon.

I quelled those sentimental thoughts very quickly. Behind every one of these gates, often hanging crookedly, behind every garden wall or fence – usually broken – lay a personal story of distress, probably of hardship and extreme dislocation. I just didn’t know the individual stories but I was embarrassed by my trite romanticism.

It was unbelievably haunting. Along River Road, maybe one house in ten was still occupied (though not for much longer now). A second house in every ten had already been demolished. The remaining eight were empty. Some were clearly damaged badly, others less so. But as the people move out, the vandals move in. There was graffiti everywhere on top of damage that was not always earthquake related. That edge of lawlessness and sense of only just holding the ugly side of humankind at bay adds to the feelings of tension and dislocation.

I imagine it is like London after the Blitz. There is no quick fix here. It will take 20 years before the new face of Christchurch takes over and entire generations will have been changed forever by the experience of living through the new normality that is life in that city.

So what happens to formerly loved suburban gardens that are abandoned?

Grass grows but rather than long, rank, greenish mix of grasses that we get in wetter climates, this is tinder dry and uniformly brown. The fire hazard is such that some properties with larger lawns have clearly had the grass cut, presumably with line trimmers, as a safety precaution.

Trees and shrubs survive and keep growing and flowering. But without a garden owner trimming them back, they encroach ever further, making passage difficult.

Wisterias were obviously much favoured and will survive no matter what. Unpruned, they are stretching out their tentacles in every direction, taking control. The same is true of ivy.

Hydrangeas and roses, growing ever larger, flower on.

Only the toughest of perennials survive and probably sooner rather than later, the convolvulus will smother everything. That is if the perennial pink climbing pea doesn’t get there first. It was interesting to see gorse and broom moving back in to inner city locations. It is likely that this was the effect of liquefaction bringing long dormant seed to the surface because it must be many decades since these plants were grown in inner city Christchurch.

Formality and garden design disappears very quickly. It made me reflect that the whole notion of formal design is an imposition by humans on the natural landscape. Left to its own devices, nature moves straight back in and blurs all the hard edges before swamping them out altogether. In fact there are few right angles left anywhere in that area. Everything is dislocated and angled off the true and formerly straight lines waver, even on the roads.

The contrived water features just looked sad, tacky and derelict. They were bereft of any water. I guess the watertight seal on most had been broken when the ground heaved so violently and the long dry summers mean there is no accumulation of rain water.

It wasn’t actually depressing, more disconcerting to find a formerly pleasant and staid leafy suburb turned upside down.

To then visit the nearby New Brighton community gardens was like a breath of life with a vibrant community response to a shared crisis. Community gardens are sprouting like Topsy. I was told there are over 30 of them now throughout Christchurch but their story will have to wait for another day.

Plant Collector: Nolina syn. Beaucarnia recurvata

Most readers will know this as a pony tail palm, usually sold as a pot plant when it is maybe 25cm tall. You will find them in the house plants section in supermarkets, chain stores and garden centres because they are reasonably tolerant of indoor conditions with good light levels. Even as young plants, they start to develop a distinctive bowl at the base with a single stem topped by a tuft of long green leaves. As they come from Mexico where they grow in hot, arid conditions, it is a bit of a miracle that our plant is still alive after fifty or so years in conditions that are anything but.

It is rare to see these plants flowering out of the wild because they need to be quite large and mature before they bloom. Our plant is about 4 metres high. Had one side not rotted out, the bowl at the base would measure well over 4 metres in circumference. However, we have 2 metres of brilliant bowl and a near horizontal line across the back. It is a miracle the plant hangs on and we had thought we might lose the whole thing to rot but it seems to manage. These plants are close relatives of yuccas which makes them members of the Liliaceae group but they are not spiky in any way.
