Free container-grown plants for planting in Autumn

We have re-activated our little cottage nursery that supplied Council restoration projects and home gardens from about 2004-2006. Hundreds of native seeds fall and grow, even in our own little garden and gravel driveway, so we have been potting them up in recycled pots with roughly-composted wood chip mulch so our garden restoration clients can have free plants for planting season (or earlier if they have a loose soil and are prepared to water them…but Autumn is much easier!)

We are now offering 10-20 plants (depending on size), in a limited range of species – this year we concentrated on kawakawa, karamu, nikau and Carex – free with every 10 hours of gardening or habitat restoration, while stocks last.

We will look after the plants till autumn.

Here’s what they look like at present:

Cool summer evening gardening

One evening last week, putting out the compost turned into an after-dinner garden wander – a weed to pull out here, a “volunteer” tomato seedling to pop in there – and I realized this is how it will be for the rest of the summer, just like every other year; the cool stillness of evening and gentle sounds of roosting birds keeps me outside till dusk.

For this shade-loving gardener, it has already become too hot for work in the afternoons except under or among big trees.

It occurred to me that there may be people who would like an evening garden ecology assessment, learning session or even their weeding done, when they are home and can collaborate or advise.

Free native plants for your garden’s wild spaces

In the 5 months we have been working with some of our gardening clients, they have learned to recognise and make use of the wild native trees, shrubs and grasses that spontaneously grow all over the North Shore, from the soil’s seedbank from former forest and wetland, or from seed and spores brought by birds or wind.

In this time, even small areas of mown lawn, or gardens containing only the common non-native ornamental species, have produced a few tanekaha, rewarewa and kahikatea seedlings, lots of baby Cabbage trees (Cordyline australis), five-finger (Pseudopanax), Karamu (Coprosma robusta) and mapou, (often referred to as Pittosporum, though it is actually Myrsine australis), and numerous native grasses, sedges and creeping ground covers.

Of course, those who are lucky enough to have a patch of native bush in or beside their garden, and some undisturbed areas of ground, have seen all kinds of forest species emerge and thrive, including native vines, ferns and orchids, and the less common “forest giants” like tanekaha, kahikatea, rewarewa and kauri.

For new clients, or as a “stand-alone” service, we provide a 1.5 hour assessment of your garden’s potential for visual transformation and the recreation of diverse native pant communities, solely through plant identification, soil protection and chemical-free weed control.

Michelle’s Bank-top Bush – Pigeonwood seedlings among the weeds

Our client Michelle has a large front garden on a slope above a quiet road. Around the edges of this garden there are several large exotic trees, and numerous smaller native trees.

Michelle in her garden – transformation begun

When we started working on this garden transformation, the fences on all three sides were overhung by ivy, which had climbed the fences and the smaller native trees on the other side of the fences, and about 10 metres up a large Norfolk pine. There was also some honeysuckle growing through and under the fence, with some remaining beyond our reach on the steeply sloping roadside berm.

Michelle loves walking in the local bush, and dreamed of enjoying some of that ambience in her own large garden. Once she learned it was possible, she became keen to create a shady little bush-walk by converting the lawn and weedy borders of an unused part of her own large garden to a mostly-wild native plant community, solely by weeding, protecting the weeded ground from trampling and desiccation, and nurturing the wild native seedlings that would arise.

We set about cutting and uprooting as much as possible of the ivy,

oxalis and grass weeds uprooted and/or suppressed with pulled weeds and cut ivy from the fenceline

and cut, uprooted or suppressed the major weeds around the edges.

Hundreds of tree privet seedlings in the borders were easily uprooted while the ground was wet during winter, and larger ones, along with other tree weeds, were suppressed with a versatile pruning technique that leads to the weed-tree’s death over a year or two.

at the base of a large Norfolk pine and a young totara, (left) a wild Macadamia seedling being suppressed by pruning, and helping to suppress other weeds, including ivy and Agapanthus which were later uprooted easily

Many native tree seedlings had already arisen wild among the weeds, and were released over a month or so to provide the basis of the new bush garden. As is usually the case, karamu was the commonest wild native,

one of the many wild karamu seedlings found hidden by the invasive and very dominant Blue corn-lily (Aristea ecklonii – suppressed, top left and foreground – later easily uprooted)

but as the hand weeding proceeded over the next few months we also discovered many wild mapou and houpara seedlings, and several rewarewa.

Today we were thrilled to find two wild seedlings of pigeonwood (porokaiwhiri, Hedycarea arborea).

We have seldom seen pigeonwood outside of forest reserves. These seedlings have appeared in Michelle’s garden under a large Norfolk pine and young totara, with many species of trees and shrubs nearby, including those that attract birds that feed on berries.

There are no pigeonwood in this or neighbouring gardens, so a bird has fed on pigeonwood somewhere else, then come to Michelle’s garden to eat; perhaps the berries of native karamu, mapou or houpara (five-finger), or the exotic (and invasive) cotoneaster, ginger or Mexican fan or bangalow palms.

These two pigeonwood seedlings germinated among ground-covering weeds including Aristea ecklonii (Blue Corn lily), oxalis, ground-runners of ivy, kikuyu and Veldt grass. Fortunately we had suppressed most of these weeds a few months ago, leaving all the loose weed material as a thick mulch to rot those that did not uproot easily.

Today we were able to uproot most of the remainder of the weeds, and used the newly pulled weeds to mulch a little more of the lawn’s weedy edge. The soil after weeding is a lovely loose loam, full of composted weeds and lawn clippings, making a seed-bed that will support many more seedlings.

However, the soil surface is drying out fast now the prolonged rainy period is over, so we placed handfuls of weed-material around each of the native seedlings, and shaded small seedlings and bare soil (potential seedbeds) with the woody ivy branches which had been cut and piled over the last few months.

The leaves still hanging from the cut ivy branches provide a scattered partial shade, and the woody branches will keep their shape well into summer, providing a “tent-frame” over which other plant materials can be hung once the ivy leaves fall from their branches.

Not all seedlings survive, especially outside of the shade and protection of a compatible plant community. We hope to update you on the fate of these two pigeonwood seedlings in a future post.

Wikipedia has this to say about pigeonwood:

Hedycarya arborea, commonly known as pigeonwoodporokaiwhiri, and poporokaiwhiri[1] is an endemic tree of New Zealand. Found on both the North and South islands of the country, the tree grows to a height of 15 metres. The leaves are oval shaped with shallow serrations. Ripe fruits turn red and the plant received its common name back when it was assumed that the New Zealand wood pigeon particularly favoured them, based on observations of the birds eating the fruit. It has since been discovered that the New Zealand wood pigeon does not prefer these berries, and tends to eat them as a ‘famine food’ when better fare is not available”.

Availability for new clients

Chemical-free weed control for two of our major garden restorations has now been completed and those projects now only need monthly maintenance. This means we will have 8-10 hours a week free for an intensive start to one or two new garden restoration projects where some rapid transformation is needed in addition to the longer term transition to a low-maintenance outdoor environment.

Learn more about our garden services, what to expect, and how we do it.

Below: the narrow space between house and fence (1.5m including a paving block path, out of view in the foreground) has been transformed from kikuyu, bare clay and weed trees to native shrubs and trees that need only annual pruning to maintain access along the path directly beneath the windows, from where the residents can watch kereru, tui and songthrushes eating kawakawa fruit in summer.

Foreground left is a nikau, about 10 years old and a metre high. Each year for the next 20 years, one of its 2 or 3 new leaves a year will grow towards the house, obstructing the path, but in this seldom-used area it can be pushed aside, or if necessary tied back or even cut off.

Much later, it will present only a single trunk, and each year two or three of the leaves, canopying the path and surrounding garden from above, will fall to the ground and be carried down the back to add to the natural environment (and invertebrate habitat) under larger trees.

There’s nothing more splendid to watch from your kitchen table than a kereru feasting on nikau fruit an arm’s length away, but if the big leaves are not for you you could skip the nikau and just have karamu, kawakawa and smaller shrubs and groundcovers, such as the sedges (Carex lambertiana) shown here. A couple of seedlings planted here have multiplied themselves by both seed and division, and will continue to spread until they cover the ground without further intervention.

North Shore Wilds garden services

We started this business just before Christmas last year, encouraged by comments from people who have enjoyed watching the progress of Gahnia Grove, the restoration project in Eskdale Reserve which we began in 2018 for pleasure and for our own further research into the most economical way to control weeds and restore the plant communities native to this area.

Our methods of restoring or creating outdoor order and beauty are very different from what is commonly practised commercially.

For example, Phoenix palm seedlings quickly become deeply rooted. We never dig them out. The photo below shows two of them, each controlled within seconds by knotting its few leaves.

Save on hedge-trimming costs

Like the fairytale Ugly Duckling, an invasive weed tree in a hedge will keep you busy, not with feeding but with endless pruning.

Whether you have a driveway border, ornamental garden or a patch of bush, you can reduce the costs of trimming and pruning by accurately identifying the “ugly duckling”. In the photos below, the ugly duckling is a tree privet in a regularly trimmed kohuhu hedge.

We controlled this tree privet for our client by our specially developed technique, which reduces the tree in a matter of minutes, and kills it over a year or so.

Repeat interventions to control the regrowth will take only a minute or two, perhaps once a month for a while, and then less frequently until the tree privet dies, probably within two years. Well before then, the dead trunk will be hidden among the foliage of the hedge.

Our technique kills tree privets up to at least 5m high without chemicals or felling. In our experience so far, it takes 1-4 years for the tree to be very obviously and completely dead.

In the fairytale, the Ugly Duckling grew up to be admired as the beautiful swan it was, but the tree privet becomes increasingly unwelcome as it pushes aside and overtops its plant neighbours. It can even outcompete forest trees in partial shade.

We often see hedges or shrubberies in which one or several tree privets are being carefully pruned along with the hedge.

While hedge trees or shrubs look neat and become leafy after a trim, the tree privet gets a growth-stimulating trim instead of being eliminated, and is soon sticking out and above again.

Once the misfit is identified, it is usually cut down. But as with many woody weeds, cutting it off near the base creates a bigger problem, for the cut stem produces a dense mass of low branches around and below the cut. These low branches are often even more of a problem than the uncut tree, as they interfere with the surrounding plants, and stick out directly into paths, driveways and lawns.

Our technique was trialled successfully in 2018 in our Gahnia Grove project on the Glenfield Rd margin of Eskdale Reserve, and in 2019 on about 20 tree privets which had invaded the native tree planting along Kaipatiki Rd opposite Glenfield College.

Depending on the thoroughness of the first or follow-up interventions, it takes 1-3 years for the tree to die. Follow-up interventions only take a minute or so.

Save even more by removing tree privets as seedlings

Tree privet fruit are very popular with birds, and a tree privet seed dropped by a bird in a hedge or shrubbery usually grows up unnoticed for a year or two until suddenly it demands your attention by outgrowing the others.

Much time and expense can be saved by identifying and easily uprooting the tree privet seedlings found in gardens or Reserves visited by birds who have recently fed on tree privet fruit.

Older tree privet seedlings less than a metre high are often able to be uprooted easily when the ground is still wet from winter rain.

When uprooting is not immediately easy or would dislodge soil or disturb other plants, we partially break the stems to starve the roots. The whole plant can be easily uprooted some time later, if desired, or left to decay in place (eg in sensitive habitat or unstable slopes).

Large old tree privets already providing shade and erosion control

Tree privet grows very fast, up to at least 20 metres high, and can live for 100 years.

While it is well worthwhile removing seedling and juvenile tree privets where there is alternate vegetation, mature trees need to be assessed individually, as they are providing many functions.

Above: A number of tree privets that grew up unnoticed in the last 20 years now form an important part of the forest canopy providing essential shade to Kaipatiki Stream

In or beside young native forest, an unrecognised tree privet will grow up to obscure and overtop all but the tallest trees. Once established, it may have become a vital part of the ecology of the site, contributing to water quality, soil conservation, the diet of birds and other fauna, and the health of surrounding vegetation.

Below: fruit on mature tree privets in native forest canopy

Below: tree privet about 10-15m high in native forest beside Kaipatiki Stream, Glenfield. Since native vegetation on the opposite (roadside) bank has not succeeded here due to grass, shrub and vine weeds combined with flooding by both piped and unpiped stormwater, this particular tree privet is one of several along this part of the stream forming the tree canopy, so in addition to feeding birds, this one is providing life-giving shade to protect water quality and freshwater ecology, including native freshwater fish and eels.

Time to act before the Spring rush

Just a reminder that Spring is underway as far as the plants are concerned, and weed vines and shrubs are putting out new shoots, sneaking around garden shrubs, drinking up the lovely water and increasing sun, and finding new ground to conquer.

Big weed invasions yield the most material for paths, mulch and compost, and the first big weeding produces a massive amount of plant material to be either sent to landfill or used to benefit the soil and plants by decomposition onsite.

Once the ground dries, sun comes out, and rain is infrequent, decomposition by rotting slows down or stops altogether.

We don’t encourage storing big piles of dry woody or papery material during the fire season, so if you have a lot of woody weeds to be dealt to….that is, vines, shrubs or trees…work needs to start very soon if you want the plant material composted onsite and returned to your soil to help the remaining plants grow well and remain weed free.

After we have done weed control and mulched where needed, the Spring rush of weeds doesn’t occur for most species, and not at all if we have had time to eradicate the weed before the warm weather.

Instead, the wanted plants grow luxuriously in the moisture and sunlight of Spring, filling the space and reducing weed reinvasion.

Since we only started our business last Christmas, we don’t yet have photos of our clients’ gardens in Spring after our weed control.

Below is a photo of an area of public Reserve in January this year, hand weeded of major environmental weeds, then gradually of benign leafy weeds. This area is part of a forest margin, in which density is key to keeping the area weed-free, so native regeneration has been allowed to fill the space entirely.

Finding the hidden treasures in Tradescantia

A native “Shaking brake” fern sporeling growing in Tradescantia

Almost every gardener knows Tradescantia ( Tradescantia fluminensis, aka Wandering Willie, etc). And many of them see it as a curse.

However, seedlings released from Tradescantia by careful handweeding usually include both natives and invasives, and they flourish in the humus created by decomposing Tradescantia.

The mahoe, toatoa, ti kouka, karamu and karo seedlings in the photos below are just a few of the thousands of native seedlings and sporelings we have found while handweeding Tradescantia in the Kaipatiki suburban area.

It is true that Tradescantia is relentless – though slow – in its growth, covering vast areas if unchecked, suppressing the natural regeneration of diverse native plants in wild habitats.

It is also true that it takes strategy and care to remove it completely and compost it to its extinction.

Above: Dense Tradescantia handgathered into piles for decomposition in place. Handweeding was begun furthest in the background, where the Tradescantia has been replaced by native regeneration 1-2 metres high.

Newly-piled Tradescantia around the cabbage tree is still green, while work has just begun on the area in the foreground.

Both before and after handweeding, Tradescantia’s leaves build up a loose humus-rich soil, and as a moisture-retaining ground cover it nurses seedlings and sporelings, which flourish if they are released to light at an appropriate time, and provided the soil is not allowed to dry out.

The humus and seedlings together provide for perfect regeneration of a native habitat if the Tradescantia is controlled methodically and carefully to its final eradication from an area, which can take a year or two as hidden stems emerge.

Below, June 2020: young toatoa (Haloragis erecta) seedlings, among the remnants and regrowth of Tradescantia after handweeding.

Many of these toatoa grew to a metre high here, helping revegetate a bank left bare by the removal of honeysuckle and dense Tradescantia.

Below, April 2021: The same bank, the toatoa on the right in foreground and midground. The young karamu, mahoe and ti kouka trees survived prolonged drought , sheltered and shaded by the shrubby toatoa that emerged spontaneously after handweeding of a major weed invasion which was followed by Tradescantia.

The image comparison below shows the same area during Tradescantia control in the foreground, as far as the tall ti kouka centre background. (The area beyond was left covered in Tradescantia for a few more years to avoid dessication and weed invasions more difficult to control, such as Creeping buttercup and Paspalum).

Drawing on our experience and photo records of handweeding for ecological restoration, we look forward to illustrating more examples as time permits.

In the meantime, you can see a description of our general methodology here.

Transform your garden to a low-maintenance haven with chemical-free weed control

Having been providing our chemical-free garden restoration services for 6 months now, we have been delighted to experience a range of outdoor environments, advised gardeners and non-gardeners alike on our unique methodology, and seen them enjoy the results.

Some have been short-term restorations, recovering a well-planned garden from just a few years of weed invasion.

Others are long-term projects, creating the conditions for the desired plants to succeed, and for easy weed control in the future.

If you are finding your garden hard to manage, through lack of time or difficult conditions, we offer a thorough site assessment in which we will listen to your needs and wishes, with identification of both weeds and any unrecognised free, wild and low maintenance plants… including hidden gems like the native tree seedlings, kahikatea and tanekaha, discovered this week and seen below:
