Farewell to the trees

To the left has been “beautified”. To the right are the 60 year old trees to be clear-felled for more such “beautification”

Imagine if trees gave off wi-fi signals, we’d be planting so many trees and we would probably save the planet too. Too bad they only produce the oxygen we breathe.” So runs the meme that swept social media recently. Truly we despair here at how hard it is to keep established trees and how ready are so many people to take the chainsaw to them.

Perhaps it is due to our recent pioneer history that we have failed to develop a reverence for big trees. That, and the fact that our houses are notoriously cold in winter and we want every bit of sun and warmth we can get.

There is no argument that large trees in suburban settings can be a problem for residents, especially as sections get ever smaller. That is why we have always advocated for trees in public areas where they have the space to reach maturity and to give grace to our environment. All power to council arborists and parks staff who are tasked with looking after such vegetative assets. For assets they are, although not in a financial sense. A tree can be chainsawed down in a morning but it may have taken a very long time for it to ever attain stature.

Leave it to the populace – the ignorati – and we would have nothing taller than 3 metres and older than 20 years in urban settings. Can you imagine the main streets of Cambridge without the trees? I do not know the history of those trees but it is a fair bet that there have been efforts by some people over time to take the chainsaw to them. Thank goodness those tasked with the civic environment have stood firm for, without those trees, Cambridge would just be like any other unmemorable small town in New Zealand.

There is no doubt that trees can make a mess. It is called the cycle of nature. Do they make a bigger mess than humans? Would we rather live in paved, concrete wastelands to avoid the leaf drop, the seed dispersal, the spent flowers, birds’ nests and occasional fallen branches?

I write from the heart. We are truly distressed because it appears that we have lost a local battle to save the row of handsome pohutukawa that line the Waitara riverbank. They are sixty years old, just achieving the beauty and stature of established trees, but they are to be clear felled.

“Those trees are past their use-by date.” Ah, no. Pohutukawa have no use-by date. They are a very long-lived tree. “We don’t want them getting too big.” “They are messy.” The fact that they are in a position where they do not shade any buildings and their natural fall of litter does not affect any private property is irrelevant to these folk. “They are not native to this area.” That argument is specious. Not only is the natural occurrence of pohutukawa a mere 10km north of here, but these same folk will think nothing of replacing them with a golden robinia or flowering cherry.

In a battle of jurisdiction between local authorities, where power has been vested in an engineer, the good burghers of our local community board have reportedly been out asking people: “Do you want to keep the trees or do you want the area beautified?” That is a Tui billboard moment.

There is no way to reason with people who see no merit in trees. There’s none so blind as those who will not see and minds have been made up. To such people, trees are completely expendable and of no beauty. They will be long dead before any replacement plants can reach maturity and in the interim there will be decades of a windswept, bare riverbank. It will have an expensive boardwalk and some seats painted sky blue, however, for beauty and history lie only in man-made objects. We could weep.

This is not a story unique to our area. It is repeated often up and down the country in some form or other. Trees need human protection if they are to hold the chainsaw massacre brigade at bay.

POSTSCRIPT
I see back at the start of 2007, I wrote about these trees in the Taranaki Daily News, saying: “Waitara would be a bleak little town without these splendid trees.

These trees were planted to hide the ugly sight of the old freezing works. Unfortunately the trees are to be removed but the arse-end of the freezing works will remain. This is, apparently, “beautifying the area”.

Tightly clipped azalea hedge

Tightly clipped azalea hedge

Azalea hedges
I finally came across a gardening idea I have read about, even suggested, but had yet to see in person – a tightly clipped azalea hedge. This is in the garden at Wairere Nursery in Gordonton and it is delightful. It is Azalea ‘Kirin’ and the flowers were just opening a few weeks ago. It will be a swathe of colour as the season progresses.

If the pretty candy pink flowers are not to your taste, ‘Kirin’ one of the Kurume azalea group – small leafed, small flowered azaleas from the Kurume area of Japan. There is a range of colours in the Kurumes – well, azalea colours so we are talking white, pinks, salmons, lilacs through to deepest pink almost red. The Kurumes tend to have much smaller leaves than the Gumpo hybrids which is why they clip better as a hedge. When not flowering, it will look similar to a clipped buxus hedge – from a distance at least.

The beauty of azaleas for hedging is that they only need clipping once, maybe twice, a year and sprout again from bare wood so can take a hard hack if needed. The more you clip, the denser the hedge will be but you need to time it right so that you are not cutting off the flower buds. The flowers are nature-friendly, unlike buxus which contributes next to nothing to insect and birdlife, and they will light up a dark winter’s day, even more so if you go for colour rather than restrained white. The problem will be finding enough plants of one variety if you plan a longer hedge – you may have to be patient but the wait will be worthwhile to get such a pretty and practical effect.

Plant Collector – sasanqua camellias

028Gardening is wonderfully cyclic on an annual basis. I know I have written about sasanqua camellias before but each year they flower prettily yet again. These are the Japanese camellias that light up the late autumn and early winter. There is a softness to the blooms which is in contrast to the stiffer japonicas that flower later in winter and early spring.

If you live in Auckland, it is the law to plant only Setsugekka, a big growing white sasanqua. I jest but that is the one you will see there at a ratio of about 20:1. In fact sasanquas come in all shades of pinks, bicolours and even reds as well as the fraightfully restrained whites. Going clockwise from left in the photo are: Elfin Rose, Gay Border, Bettie Patricia, Silver Dollar, Bert Jones and Crimson King. Some may no longer be available on the market but there is usually one that will look very similar.

Sasanquas can be slow to establish but left to their own devices, will make light, airy, large shrubs over time. They also clip very well so are ideal for hedging and topiary. When clipped regularly, the growth is much denser. The foliage is smaller and often darker green than many other types of camellias. Some describe them as fragrant. They have a distinctive mossy, slightly earthy sort of scent – it is one of the defining characteristics of a sasanqua.

Outdoor Classroom: multiplying succulents

Photo 1If everybody realised just how easy it is to strike succulents from cutting, nobody would buy these plants unless they were new or exciting. This Crassula ovata (Jade Plant or money plant – very good for feng shui, apparently) could easily generate 30 good sized plants or many more smaller ones.
Photo 2The ground-hugging types which form rosettes are easy to lift and divide. As long as they are replanted in full sun with excellent drainage and light soils, each little rosette will form new roots when nestled into the soil. Tidy up the rosette first by removing dead leaves to avoid them holding moisture in the rotting foliage.
Photo 3Even succulents with well defined branches will grow. This is Aloe plicatilis or the fan aloe. Unlike usual leafy cuttings, succulents can be struck from very large pieces and you can expect close to 100% success rate. Cut to a balanced shape. Place the cutting in an airy spot and leave it for a few days to dry out. This reduces the chance of rotting before it creates roots.
Photo 4Stick the cutting into a pot filled with a free draining potting mix (we use granulated bark) It is better to use a mix which does not have much fertiliser in it but this is not critical. You can equally put them straight into the garden in a free draining, dry position. It may be necessary to stake the top if you have a heavy cutting so that it remains standing. Do not try and keep it firm by compacting the soil or potting mix because you want maximum drainage.
Photo 5Make sure that the cutting does not get waterlogged while you wait for it to form roots, but it will need an occasional wetting. In a few months, most plants will have started producing roots but it will take time for a large or heavy cutting to develop enough of a root ball to keep it standing upright.
Photo 6Most succulents, including the popular burgundy black aeonium whose name few can remember and even fewer can spell (Aeonium arboreum ‘Zwartkop’ or ‘Schwartzkopf’), sempervivens, aloes and many cacti can be increased this way. It is a good activity to share with children.

Garden Lore: May 23, 2014

“Momordica – Cucurbitaceae – The Squirting Cucumber. An annual gourd-like plant, with woolly leaves, and yellow flowers, the fruit of which resemble a small cucumber; and which, when ripe, bursts the moment it is touched, scattering its seeds, and the half liquid, pulpy matter in which they are contained, a considerable distance. This quality made it a favourite, in gardens, a century ago, when some people were yet in a state of sufficient barbarism to find amusements in the annoyance of others; but it has now deservedly fallen into disrepute, and is seldom grown.”

Jane Webb LoudonThe Ladies’ Companion to the Flower Garden” (1840)

Vegetable time bombs, we call them

Vegetable time bombs, we call them

Garden Lore: Magnolia Little Gem

I stopped to photograph this driveway in town because it is like a vegetable time bomb waiting to give its owners no end of problems. What you are looking at is a narrow driveway flanked on either side by avenues of Magnolia Little Gem. At this stage, it still looks quite attractive. Little Gem is a good looking plant with glossy, dark green leaves and brown felted indumentum beneath. In summer, it will sporadically produce attractive white flowers. The mistake often made is in thinking that the descriptor “little” in its name, means it will stay small. While it will not get as large as some of the other grandiflora magnolias, it is still going to be an 8 metre tree and have a spreading canopy. You can already see it spreading.

In narrow spaces, you need narrow, columnar trees (technically ‘fastigiate’) which can give height and structure, without width. If you are going to choose a plant which forms a canopy, you need to keep the branching above the height of vans and small trucks – probably 3 metres up. Clip and shape from the very start so that you don’t have to undertake radical work when the trees become a problem.

It takes a lot more effort and expense to remove established trees which have outgrown their allotted space than it takes to plant them in the first place. It is better to get the selection right at the start.
