Bittersweet seeding2

On the move
As seeds take root
Adapted to a new environment
Displacing the natives
As their niches disappear
In a every changing landscape

Kudzu infest

One that we have played a hand in
In our wanting to control nature
To what we think it should be
Riches in the earth
Taken for our own needs

Weekly Photo Challenge: Threshold


DSC06144

Sometimes it is the the images and words of others
That are woven into ones’ own experience
Patterns are form
Never able to go back
A different view of the world
Beyond what any one person could live
Of good and bad, but hopefully never indifferent
Stepping over the thresholds
Knowing that one can never know all that is
Yet, maybe being able to see some things a little clearer

Weeds, Invasives and Books Part 2

Sometime beyond 30,000 years ago the climate had changed, and the cold and ice advanced out of the arctic covering a large portions of North America, Europe, and Asia. The ice sheet was estimated to be a mile thick and with so much of the water of this planet frozen, the oceans were as much as 450 feet lower than they are today. As the ice sheet advanced to cover what we now call home, it had scraped and scoured the earth carrying soil particles, boulders and anything living in its’ path that couldn’t flee its’ approach. The areas south of the major ice sheets were what might be considered sub-arctic; a tundra and open boreal woodland with very little rain. Around 13,500 to 11,000 years ago the ice sheets receded and the flora that had managed to survive south started to advance north and grow in…

A Multiple Personality Disorder


P1020071

I’ll say that “life was much simpler once”; at least in a world of gardening and yet it most likely because of the theory that ” ignorance is bliss”. I once was a wooden boat carpenter who when I had my own business it was at my former home and I probability spend more time in my gardens than working on boats. I lived in the middle of the woods, where my gardens were, it was on the land that had been cleared by the former owner for fire wood to heat their little house in the winter. It was a joy to go from nursery to nursery picking out plants and then trying to find a place where they might fit, to spend hours weeding, creating new beds. My gardens were well tended, at least up to the time that I changed professions from a boat carpenter to a person working sales at a plant nursery and being part of their landscape crew, and then my gardens began to transform. For they began to have manage on their own, many of plants were lost, others grew with a vengeance and design and ideas what I had planted began to disappear and the forest started to reclaim its own. I wind up becoming an observer rather than a participant, for many hours are required to work in horticulture field during the season.

015 (3)

It has been a long evolution from a period of bliss to now where my feelings are much more confused; for as I have furthered my education about plants, designing and the natural native landscape I have developed a multi personality disorder. Why not start with lawns for it is a huge part of this profession, it a multi -billion dollar industry from those that provide seed, the chemicals, to the sellers of soil, compost to all of those that sale equipment from mowers, weed wackers, irrigation you name it, it’s out there; with new, improved products every year and to all of the landscapers who job it is to maintain it, keep it green, looking lush and free of undesirables. Then the question is what becomes of the chemicals with names we (or I) can’t even pronounce and wonder what harm they do to us and to all the other living things out there, or do we consider going organic? Even organic requires a lot of inputs, to offer organic the inputs are to feed the soil, that feed the grass. It certainly is a better option than what we call typical lawn care.

013 (2)

Yet do you ever wonder why have a lawn? Where did our idea of a lawn come from? Where it is largest portion of any landscape we might design. Now, I am person sadly that never gets that excited about lawns or cutting my own grass, I do it more so just to keep my neighbors from cursing me and I don’t my clients lawns. When I used to live in the woods I had very little lawn, only for paths and over my septic system and it was nothing I ever planted rather it was grasses and plants that stayed green after walking or cutting it. There were many stone outcrops which meant I couldn’t use a lawn mower instead I used a weed wacker and when it broke, my lawn quickly became a wildflower meadow, not something planned, but from the plants that were already growing there, but when not cut they grew to be 2 feet high, with all kinds of flowers mixed in;becoming a different kind habitat with insects, birds I had never notice before. I let it go for the season and then after I cut some parts and let other parts go, which made my ex-wife much happily. It is a nice idea of a creating meadow rather than lawn, but for where I lived it was landscape of transition for it never would remind a meadow without my intervention. What kind of meadow it might be depended on what was there to begin with, what might introduced by me or the surrounding landscape. What kind of meadow it might be also depended on the soil, water and how it was maintained. when is it cut would determine what would survive, what went to seed, what grows close to the ground that can take repeated cuttings. And if I stop cutting, it would move on to shrub land, then forest.

101

With this in mind and thinking of design, on a few occasions I have been ask by a client to create a naturalistic landscape, but when I look around the site maybe in the woods, that had been cleared of all vegetation for the house, driveway, septic system with the idea that there is a front yard, a back yard. The woods surrounding the lot has been clean of understory plants for whatever reason I’m never sure, and the client wants it to be natural with flowers, shrubs, maybe plantings with ornamental trees and it is a given that the rest is lawn, regardless of soils that remain. It hard not to tell them that if the site hadn’t been so disturb, with the smallest footprint of disturbance, it would have been easy to keep a natural landscape for it was already there, but what the client wants is not what was already there. For what was there, did flower, for all plants do, but it’s not the show that they or we come to expect. Nor would the client with few exceptions want their front or back yards littered with leaves, twigs, branches like the surrounding area. So we all want to create something that natural, we might think to use native plants, but were they there before or would they have shown up on their own if there had been a natural disturbance to the site? Are the soils, moisture, sunlight of the site either before and after disturbance appropriate for what are natives? This isn’t to suggest that using natives is something that doesn’t matter, it does, it should. But maybe it about much more.
A man-made landscape is never a natural landscape. Each has its own set of rules, and the conditions and outcomes of each are very much different. One is manipulated by us, the other isn’t. The design is the end, only allowing for growth and maturity. What plants started there remain, others are removed.
We’ll never go back with the introduction plants from all over the world, not knowing how they will adapt to a new environment and how they might change that environment directly and indirectly. I will mention Invasives for they are and will be very much a part of our profession and our environment. And we have opened Pandora’s box I’m sure that each of us has to deal with them now, just in the maintenance of our customers gardens. we work an area, yet just a few feet away are more that we’re not responsible for and they will be the problem of future maintenance. We in New Hampshire may have stopped selling those plants that are on the Invasive list, but there are already millions of them out there, each producing many more millions of seeds that will produce billions of offspring in the future. So as we design, using plants now not on a list, but may someday be on a list which future landscapers will be dealing with. Can a native that isn’t a native to this region or a ecosystem have the potential to act like an invasive someday?

012 (2)

So where my multi personality steps in is that there are some many different answers to the same question, what is, what isn’t; good, bad, indifferent? So when it comes to design and what is the best landscape, how do we judge? Is it color, form, texture seasonal value in our eyes and that of the customer? Does it serve the function the surrounding landscape does it supplement or compete with that landscape. Or going back to man-made verses natural landscape, at what point does one consume the other and make it nonfunctional?. We like to think what we’re doing is making it better, but it is the future that will tell. For now, I still working in peoples’ gardens, I try to design to what a customer might like. I try to suggest that less is more, native over exotic and yet another part of me is thinking let nature take its course. Why clean a garden when it’s might be best not too. Should a garden look kept and tended to? For it doesn’t seem to fit with that larger landscape that no one has designed.

Bonsais, a Circus of Trees and Every 35 feet Part 3


Oh it is a beautiful day! A nice day for a walk in the woods. We can meet at the hay field down the road and walk in, be careful to park on the field side of the road because as you will notice the field across the way it hasn’t been hayed or mowed for years and show signs of early succession with perennials, shrubs and tree seedlings and at the stone wall on the edge of the road the rosa multiflora and autumn olive has taken over and you don’t want to get too close. It’s about 1/4 mile hike thru the fields, but it shouldn’t be too bad as the fields have had its’ first cut and is just starting to grow anew. As we look what is growing here we see timothy, clover, vetch and annual and perennial grasses such as orchard, rye, switch grasses and maybe other plants that we might consider to be weeds. but for the person who is cutting this field they do try to keep out plants that might be poisonous to horses, cattle and other livestock and introduce plants that might have higher nutritional value. We notice an area that hasn’t been cut and the reason for that is that there are ground nesting birds like bobolinks or meadowlarks who’s brood has yet to fly off from the nest. How this field is maintain is a factor in what plants grow here. If the field were to be mowed once a season we might find that plant species would change over time, for plants that might take longer to flower and set seed might start to replace those that can survive being cut two or  three times a season, and if as some time happens, this field is used for grazing of livestock, again over time the plant composition might change again due to the greater input of fertilizer in the form of manure and what plants can survive being grazed on.

We move on and before we reach the edge of the woods we come upon brook and some wetlands and we notice the signs of  a past beaver encampment on the brook, large girdled dead trees some distance from the brook, beaver chewed stumps and maybe the remnants of their dam. When the beavers were here they would have ponded the area upstream, the expanded  the wetlands that were already here and change the flow of the brook downstream. The area around the pond would have changed ; trees were taken down by the beavers or died from the soil becoming saturated or being girdled and some remain standing. Whether the beavers were evicted or they had moved on to new food sources, this is area is one of transition with the pond being gone, the wetlands area being reduced as the soils dry out and others plant species able to grow  here again. Even if the beavers hadn’t populated this area, this brook and surrounding wetlands might still be going to changes; from changes in the brooks’ flow either from changes in precipitation or divergence of the water flow upstream, whether natural or man-made  and/or deposition of sediments in the area from land disturbances upstream.

As we walk along the edge of the wetlands to the beginning of the wooded area notice that forests’ edge is dense with many shrubs and younger trees we might also notice that some non-native and some invasive plants have managed to get a foothold here with their seed being deposited or blown in from surrounding areas. We walk in to the woods we notice it is a bit cooler, the sunlight only reaches the ground in little patches, the understory plants and trees seedlings are more scattered. As we walk on we see the changes in tree dominance in one area beeches might have larger numbers than oaks or maples. There are larger size beeches  with surrounding younger ones that haves spouted from the older trees roots. we travel a little farther on  we see oaks and maples mixed with white pine, white ash, hemlock and spruce. Off to side there is dense hemlock stand with nothing growing underneath except for some smaller hemlocks that may be older than their size would indicate, their growth is slow as they wait for an opening when the sun might reach them and then they can take up the space allowed them. We also notice changes in the understory plant material some plants in abundance in one area but not in other areas, including ground covers, sometimes more plants growing where more sunlight reaches the ground. Maybe a tree or trees were blown over in a wind storm allowing more light to reach the ground. We see evidence of past openings with ‘pillows and cradles’ which are mounds next to depressions which indicate that trees had been blown over raising the roots out of the ground and being that the trunks  or roots having decayed  and the soil dropped where the roots were.

As we have been walking we have notice  series of stone walls which indicated that this land had been cleared of forest and was either farmland or pasture maybe dating back more than a couple of hundred years ago. At some point this area was abandoned as farmland and allow to regenerate to forest, we can assume this from the few trees that may have been here for a hundred years or more. Yet we notice that many of the trees by their size may not be more the fifty years old, so we can also surmise that these woods had been logged again and the older trees were left because they didn’t have any timber value or were in locations too difficult to cut and remove.

We all have different perspectives to what these different habitats are and what they mean, and we are just beginning to understand how each of these habitats do effect each other. How changes in one area might have impacts on surrounding habitats from natural or man-made changes or how continuous changes in each affecting the other. They are unique environments that are woven together by the soils, types of organic debris,  micro-organisms, moisture and water, flora and fauna. One can spend a life time observing  and studying it and still not know or understand it all.

We have reach the top of the hill from here the trail to the right heads off to a old gravel pit long unused and you would see that plants are just starting to get a root hold, just here and there and most likely will take decades if not a century  to built up enough organic material to once again become a forest. To our left we look out to see the development below, residential neighborhoods, shopping areas. One thing that might strike you is the vast difference between what we have just experience with our walk and much of our man-made landscapes which mainly is one of well structured islands in seas of black and green. Trees and plants nicely spaced, evenly organized, one of these, three of those or massed plantings for  that visual impact. The reason for our walk is about  landscape zoning ordinances for if we didn’t have any ,how much worse might our landscapes look? Areas of lawns might be just black top or left as gravel. It would be left up to those who enjoy landscapes and gardeners  who always want to add something new to their  homes verses others who just don’t care what it might look like. Some we create laws about landscapes and lawn in the hope to improve the quality of all our lives, to bring our changes to the natural environment from development  and keep the natural integrity of the supporting landscape. The trouble is when laws are written they meant to be clear and understood by the majority and carried out by good hardworking folks who don’t know much about  the nature of trees, plants, soil habitats, what their requirements and how they might  impact the natural ecosystems. We can try to control issues of water, pollution, vegetation and it impacts on us and our environment, we write ordinances that call for a tree every 35 feet, shrubs every 6 feet along the perimeter which is certainly better than none, but how does that fit to a natural environment? When ordinances requires ‘ x’ number of trees and shrubs for ‘x’ number of parking spaces planted within the lot; where rarely they remain healthy or even survive given root space, soil conditions; might it not be better to use that plant material to create natural buffers and leave the parking lot for cars.

We have over time develop an ideal of what  a good landscape should be, that includes lawns, foundation plantings and with islands here and there.  Yet next to the natural landscape does it really fit or does it belong? What if I decided to stop mowing my lawn, allow it to become a meadow; might someone come to my door and cite me for an un-kept lawn? How would I explain my reasoning to that person who can understand what a lawn should be, but not a meadow? How would the neighbors feel if I let my landscape go ‘la natural’, let nature take its course?  As more and more of the natural landscape is being taken over by ‘us’ and we replace what was there with what we consider good landscaping, with the technology and equipment to change our environment on an unprecedented scale and no way of knowing the long term effects  we might be having on whole ecosystems . For our parts as landscapers, designers it is time to reconsider what is a good landscape, one that takes the whole environment in account, addresses our understanding soils,  our choice of plant materials (native and alien), including grass species and give them greater importance in our changes of the natural landscape.

Weeds, Invasives and Books Part 1


???????????????????????????????

A design is put to paper, plants are installed, and the compost and mulch have been spread, the site cleaned up and the photos taken for the portfolio, and even as you walk away; a new design is coming into play. In that walk, one can look around at the surrounding area of your project and begin to see the future and it might even be from the pieces of root, rhizomes and seeds that are in the soil of your finished landscape. For as much as we might consider the project as neat, orderly and creative, it is also a matter of disturbance and a void from it previous state; when that space was filled and covered by the trees, shrubs, herbaceous plants that had found their niche over an extended period, but now it is an area of opportunities to be filled with new plants and usually they are the ones that have evolved to best move in before others can even spread their roots. From the first person who decided to grow something, first for food and then maybe for pleasure, it required that person to make room for it, by removing the vegetation that was already there and then had to ‘weed’ to keep the native plants from returning either by the seeds that were in the soil and that had gotten tilled up closer to the surface or by seed and root from the surrounding area wanting to take back its’ own.

???????????????????????????????

So what is a weed? The basic description of a weed is “Something that is growing where it isn’t wanted” pretty basic that can cover a lot of things, including people. An example might be milkweed Asclepias syriaca which when it grows in it’s native environment in meadows, fields and even along roadsides it might be considered a keystone species which is “a species whose very presence contributes to a diversity of life and whose extinction would consequently lead to the extinction of other forms of life” for the Monarch butterfly depends on milkweed in it’s migration north from Mexico as it lays its’ eggs on it, which then become the butterfly that continues the journey north. The butterfly in its’ larvae stage eats only on the milkweed plant which contains glycosides a toxic substance to other animal species, which protects the butterfly from being eaten by birds. Now if that milkweed has gotten into a garden bed, it certainly might be considered a weed, its’ habits such as its’ root structure that runs deep horizontally that when you try to remove the plant most times it breaks where it is connected to the root and even when the root are gotten, each root piece left behind can grow new shoots. When it is left to flower and go to seed it can produce 200 seeds per pod and each seed has silky hairs that help carry it in the wind where it may land where it is allowed to grow or settles in another bed to be regarded as another weed. Grass growing in the lawn is what is wanted and expected; grass growing in the landscape beds is a weed.

???????????????????????????????

In the book ‘My Weeds’ by Sara Stein the author of ‘Noah’s Garden’ who’s own definition of a weed is “ A weed is a plant that is not only in the wrong place, but intends to stay” In this book she covers wide range of subjects about weeds, including the botany of weeds. How does a section of root know how to grow new roots down and new shoots up? In another chapter she writes about the ‘succession of the landscape’ and observes that in the town where she lived; it had been 80% farm land and pastures until early part of the 1900’s and by the time she wrote the book 1988 most of land had become a mixed deciduous forest; for folks had stopped trying to maintain much of the land as farm or pasture and how that land when thru the succession of plant species reverted from open land to forest. First with annual and bi-annual weeds, crab grass and a mix of other pioneer weeds that spread their seeds far and wide. This was followed by tap rooting perennials such as burdock, curly dock, vetch and tough grasses. In a couple of years the shrubs moved in and pioneer tree species. Over the years, the maples, oak, beeches and hemlocks were filling the canopy over this once farmland.

P1010734

The natural landscape is one that is constantly changing; even when it reaches the climatic stage, for there will be natural disturbances that will allow for more changes. So as far as our landscaping goes, it may take days or weeks to design and install a landscape, but it takes so much more time after the fact to keep a landscape as it was intended, and the timing involved in weeding, before different plants have time to establish, set seed and spread their roots, and what plants may be growing off some where that can throw their seed into the mix. I know even working on landscapes I had installed over the years that I now have a more familiar relationship with the weeds that keep popping up than the plants that I had put in. Or to work next to a landscape that haven’t been maintained to see how fast the changes occur and all that wasn’t intended take a firm foothold and outcompete the installed plants. Then to watch when someone finally tries to deal with it, but doesn’t know what should or shouldn’t be there as part of original plan; the area usually gotten back under control is small and never stays that way for long.

???????????????????????????????

The thing about most plants we work with in landscaping and even those plants used in agriculture is that many of them are clones of plants who’s features and habits have been breed for what we might consider desirable, whether flower, form, fall color, fruit or has some pest or disease resistance and then they are produced asexually so that they have the same characteristics, the same genes. On the other hand weeds are uncultivated, an ever mixing of genes from one generation to the next; thou maybe there is some cultivation involved, for where a weed may stand proud, shallow rooting and takes a long time to go to seed, it may never make it to the next generation, it will be those that are not easy to get rid of that will survive and continue on to the next generation and then the next. So over the course of time, in the constant battle between farming, gardening and nature that we may have breed perennial vetches, red sorrels who’s roots were made to be snapped and then grow new stems again, or a dandelion that has a good size tap root, grows flat on the ground, and even when mowed or chewed it can produce a another flower in a day and go to seed by the next. So in the book  ‘Botany of Desire’ by Michael Pollen he writes about apples and the famous Johnny Appleseed, John Chapman who traveled around the mid- west planting apple seeds which according to Pollen, most folks had used the apples for hard cider rather an eating, from the original seeds, they produced new offspring, new varieties with each genetic mix, one apple with it’s 5 seeds each will become different variety of apple tree from that of the parent tree and each other, some may be better suited to that location, some may flower a little later than the last frost and produce fruit that was more desirable. Today, when we eat the fruit of a Delicious, a McIntosh or one of the other varieties they are each grown from grafted trees that came from that one original tree that had produced that particular fruit and any seedling from its’ fruit would be a totally different apple.

So for anyone who is trying to maintain the intended landscape; it is important to know the intended and the unintended, to understand the nature of a plants including ‘weeds’; their evolution for continued survival, such as how the move about, when they might set seed, what kind of roots they have and when best deal with them. One of the useful tools you might want to carry with you besides your trowel and cape cod weeder is the book  ‘Weeds of the Northeast’ by Richard Uva, Joseph Neal and Joseph Ditomaso, published by Comstock Publishing Assoc for the pictures are good, it shows what the plant looks like not just when it is flowering, good descriptions of plant habit, leaves, roots and seeds. It covers 299 weed species – moss to grass, herbaceous to woodies and trees that you are most likely to come across.

I’ll add one final thought that is when you compare the 299 species covered in this book with The Nature Conservancy/ National Park Services composite invasive, alien weed species list; 131 (43%) of those species are on both.
