Spring cleanup


I tend to prefer to clean up the garden in the spring rather than the fall. That is when I’m motivated to do it, as I am dreaming of the spring garden and looking forward to getting re-acquainted with the plants. It’s better for the garden, too, as the dead stems and foliage protect the crown of the plant in the winter, and the birds can eat the seeds, if any. The only thing I religiously cut back in the fall are irises and daylilies, but that’s just because I can’t stand how slimy they get over the winter.

Eventually, however, you have to pull your wellies on and get busy. It’s a good idea to get the dead plant material out of the way before the new growth starts, otherwise you might cut some of that by mistake. For the most part, you want to cut perennials back to about an inch or two above the base. Don’t cut closer than that or you may injure the crown. Cut less if the new growth has already started – it will cover the “stumps” soon. Don’t cut things like roses, woody perennials (ones that have bark) early spring bloomers like Moss Phlox or vines back unless you have read up on them and are sure that they will do what you want after you cut them. Some things only bloom on new growth, and so you can be set back years if you cut them back too much. But for perennials like Echinacea, Shasta Daisies, Geraniums, etc, cutting them back can be very beneficial.


This is a picture of new growth on a Peony. If you look closely, you can see how last year’s stems have been cut back, barely noticeable now. The plants to the right and in the background have also been cut neatly.


Fallen leaves can be raked up and composted or, better still, put through a leaf shredder and put back on the garden. There, they will release nutrients all summer as they break down, and you won’t need to add additional fertiliser. I also mulch about every other year with a mixture of compost and shredded pine bark, just for good measure. The trick is to do it before the plants put on too much growth, otherwise it’s a rotten job.

And that’s it! Your garden now looks neat and tidy, your plants will be fed, and you can sit back and enjoy it. (For awhile!)

The Show must go on!

As we have done for the last two years, we participated in the Seacoast Home and Garden Show this past weekend, and had a great time! It’s is always so much fun to talk to people and hear what they are looking for in their landscapes, and to feel like spring really is on its way. (Even though there usually is a snow storm around the time of the show!)

Below is a slideshow of our display, from concept to completion. Enjoy!

Spring Scavenger Hunt


Snowdrops, one of the earliest spring bulbs.


It won’t be long before we will start to see new things popping up in the garden every day, and we will start to reap the rewards of those cold hours in the garden planting bulbs. As well as just being a lovely time to enjoy new life, this is also a great time to analyze the early spring garden, and think about what we might like to have there next year, because, let’s face it; by the time bulb planting time comes around again, we will have forgotten where everything is.

This time of year, the “homework” is simple. Look around. If the snowdrops make you happy, make yourself a note to increase their numbers, or plant some more somewhere else. If there is a place by the door that is bare, make a note of it, so that next spring you can have some color there to welcome you home. Set a reminder on your phone for Late July, when the bulb catalogues tend to come out, and sometime have sales. Then set another reminder for October, when you can buy them at your local garden center, just in time for planting. It’s a simple thing to do, and it pays off just when you want it most.

How to Prune Roses


I often get asked how and when to prune roses. Roses can be a little daunting, that is true, but once you know the general principles of how to prune them, you should be able to tackle almost anything. And many of the principles of rose pruning apply to pruning other plants, too, although you should read up on what it is you want to prune before diving in. Anyway, the most important thing to know about pruning roses is that it will be fine. Most roses are very forgiving. We all do a butcher job at one time or another, and seldom does it result in death.

The main reasons to prune roses are as follows:

  1. To cut out diseased, crossing and damaged growth
  2. To maintain a pleasing shape
  3. To allow for a healthy amount of air to circulate within the plant.

That’s it, really. You want to get rid of any dead bits or bits that are black or distorted from disease. You also want to get rid of branches that cross so close that they rub against each other. When they rub each other’s bark away, they leave openings for disease to get in. You also want a rose bush that has a pleasing shape. So you might end up cutting off a perfectly healthy branch because it messes up the symmetry. That’s ok. And finally, roses are prone to diseases, so if you can cut out stalks that clog the interior of the plant, you will allow more air to circulate in the middle and that will help keep those diseases away.

That’s WHAT to cut. Now, WHERE to cut.

Remember that every time you make a cut, the plant will react to that cut by sending growth hormones to that spot. So if you cut your rose above a bud that is facing outward, that bud, being the last bud on the stem, will now be told to grow, and it will grow the way it is facing. So it stands to reason that, if you don’t want the branches to grow inward, (see reason to prune #3) you should cut just above an outward facing bud. Are you with me so far?

Next, HOW to cut. For this, it’s easiest to show pictures. It all has to do with the angle of the cut in relation to the bud. Here goes:

WRONG. This cut points toward the bud, so rain etc will roll right down the cut and onto the bud, making it vulnerable to disease.
WRONG. This cut slants the right way, but it is too close to the bud, and so doesn’t give it enough support. Thus, it will always be a weak place on the plant.
WRONG. There isn’t anything horrendously wrong with this cut, but it’s a little too far from the bud and cut straight across. An entire rose bush pruned like this will have a stumpy appearance.
rose right.jpg
This cut is just right. It is angled away from the bud, and not too close, yet far enough away to give the new branch support.

And finally, WHEN?

I usually prune my roses in late winter, while they are still dormant. At least, I do the main prune then. I will sometimes shape them in the summer, or cut off a branch here and there. The main thing is not to prune when winter is coming and there is about to be a long period of cold. Since pruning tells the plant to react, you don’t want it to send out a lot of new growth, only to have it killed by a frost.

Hopefully this has demystified things a bit. If you are confused about anything, please post a comment on this blog post and I will try to help make things more clear.

Happy Pruning!

Natives and Invasives at the Water’s Edge: A Case Study

Version 2

This is considerably longer than my other posts, but it’s full of topics for discussion, if you have the time. Fear not, it’s the exception, not the rule!

As a landscape designer, I get to wear many hats – including, but not limited to, those of horticulturalist, artist, interpreter, arbitrator and organizer- sometimes several at once. One of my favorite hats is that of problem solver. While wearing that hat I get to stretch myself to come up with a landscape for someone that will not only make them feel better about something that has been a negative in their lives but will turn that negative into a positive rather than simply neutralizing it. I enjoy the challenge, taking the parameters that are in place and figuring out what will satisfy all “needs”, while also giving the voice to the “wants”.

Such a puzzle is always a thought provoking experience, and none more so than one I encountered in a job I was involved with a couple years ago. The job involved wetland restrictions, shoreland buffer zones, invasive plants, trespassing, angry neighbors, and frustrated homeowners. I was called in with the landscape company that I design for, to solve the problem; and the deeper we dug into the various facets of that problem the more complicated it became. When investigating the issues in depth, parts of them that had seemed to be in accordance with each other at first proved to be quite disperate in actuality, and had to be reconciled before any progress could be made. What follows is my attempt to describe all these differences, and how they deserve to be pondered. There are many soap-boxes to be climbed on along the way, but I’m going to try to stay away from them as much as possible, for whatever you believe, there’s always another way of looking at things. We will see how well I do! I will also explain how, in the end, we resolved the issue, for better or worse. I like to think it was for the better.


It all began on a beautiful, newly purchased property in Maine, with a house on a hill overlooking rolling lawns down to the water. The view was spectacular. We had previously walked around with the owners to discuss doing some landscaping at some point the following spring. A week or two after our visit, we got a call from the owner, who lived out of state at the time, asking for our help. He had contacted a local tree company to do some clearing on the property and somehow, through a series of miscommunications and lack of awareness, a large portion of the clearing had been done within the 100 and 250 foot buffer zones from the high tide mark, which is essentially illegal. And to add insult to injury, some of it was on their neighbors land. Both the town Conservation Commission and the Maine State Department of Environmental Protection have been called in and were asking for reparations to be made, the neighbors were furious, and the homeowners were understandably upset and confused about what needed to be done.

The Letter of Violation sent to the homeowners stated that a total of approximately 5550 square feet of understory growth had been cut, and in order to fix the transgression, a design or plan of action for the two areas in question needed to be submitted. The plan was required to be comprised of native plants, enough to satisfy the “point system” (more about that in a minute), and had to be installed prior to a certain date. The sizes of these plants and planting distance was dictated in detail, (in some cases to my horticulture horror, but that’s another story), as were the strict guidelines for any further cutting and for regular inspections. No permits of any kind would be issued for the property until the situation has been resolved, and the homeowners were very lucky that there was not a steep fine involved as well. To complicate matters, both areas involved were choked with invasive species.

After this very long introduction which, believe it or not, is actually a highly abbreviated version, we were faced with two areas of concern that needed to be sorted out, described briefly as follows:

  1. Replace the cleared area on the neighbor’s property with a  native planting that would satisfy the point requirements and both appease the neighbors and create a garden that the homeowners would enjoy.
  2. Create a plan for the area adjacent to the water that had been cleared, the goal being to populate it with native species, and as best possible, deal with the invasives.

Although at first glance, this might seem like a fairly simple thing to do, it was easier said than done because of a number of factors. No one was questioning the need for, or the value of using native plants. In these days of extreme weather conditions they do well with the least amount of intervention – after all, they are meant to be here. And encouraging and enabling native  plants to grow and thrive is the right thing to do for a number of reasons, not the least of which include the habitats and protection they afford wildlife. The complication came from the opposing side, the invasive species that were vying for the same patch of soil. And each of the areas where he wanted to plant natives had to be treated differently.


The area which had been cleared along the property boundary area straddled the property line and was approximately 86ft x 15ft,  incorporating a steep, stony banking. From what we were able to see, much of what had been cut to the ground (no roots of been disturbed) was Multiflora Rose (Rosa multiflora), Staghorn Sumac (Rhus typhina) and Oriental Bittersweet (Celastrus  orbiculatus). The neighbors had no intention of doing anything to reduce the further exuberance of the invasive species in this mix, preferring to allow the unruly tangle to grow back, and stated that they would request that any new planting be done on the homeowner’s side of the property line. The homeowners were happy to comply with this request because it meant that they would have control over the new plants. (This was also good because the DES required that the new plantings be replaced should they not survive a minimum of 5 years. Had the homeowners planted the new plants on the neighbors property, they were not have been allowed to cut the remaining  Bittersweet back and thus the plants would not have survived… you see the problem.)

As nothing could be done about the invasive species in the area besides cut them back from the property line, the next issue was to make sure that the proposed trees and shrubs satisfied the point system established by the State. In case the  reader hasn’t come across such regulations before, I will attempt to sum them up in a nutshell:

Basically, for every 625 square feet (25 x 25’) there has  to be eight or more points, as represented by the size of the trees and shrubs in that area. The points awarded to each tree or shrub are as follows:

Diameter of tree at 4.5 feet above the ground Points

2 to <4 inches 1

4 to <8 inches 2

8 to <12 inches 4

12 inches or greater 8

Multi-stemmed shrubs are assessed based on the number and thickness of the stems and the ultimate height of the plant.

One problem that we ran into in this area was that using the diameter of a tree at 4.5 feet above the ground is what is commonly done in forestry. In the nursery trade, however, the diameter of a tree is measured 8 inches above the ground. As a normal tree will typically flair at the base, a tree that is 4 inches in diameter at 4.5 feet above the ground is likely to be more like 6.75 inches in diameter at the base, thus having a much larger root ball than a tree whose diameter measures 4 inches at the base and requiring more disturbance in order to plant it. It was important, therefore, that we all be on the same page when talking about what sized trees and shrubs were required to replace trees whose stumps were all that remained.


As the area in question covered roughly the equivalent of two 25 x 25 square-foot areas, a total of 16 points was needed. In the end, the following native plants were chosen to satisfy the requirements, each chosen because of its suitability to the bright, sunny location and its contribution to the landscape. As natives, these plants are well adapted to the area, therefore needing less water and fertilizer, which was another important consideration so close to the water.

(1) Quercus palustris, an oak whose branches typically bend downward and so is a great choice to create a privacy screen, with brilliant scarlet fall foliage. 2 points.

(5) Amelanchier canadensis ‘Glenform’, an upright Serviceberry which would fit the narrow space better than some of its wider cousins. It flowers in the mid spring, producing edible berries and attracting pollinators and wildlife. Bright fall foliage is an added benefit. The multi trunked, large shrub/small trees counted as 2 points each, for a total of 10 points.

(8) Prunus maritima, Beach Plum. Much loved for its edible fruit (great jam) and spring flowers. This native is also salt tolerant, making it a great choice for a seaside hedge located not far from the road. One point each, 8 points.

As the area could support additional plants, we decided to err on the side of a thicker screen and a better neighborly relations and used 20 points worth of plants instead of the required 16.

Having been given the blessing of the homeowners, the neighbors, the Conservation Commission and the DES, these plants were installed along the edge of the property line. They will grow into an attractive privacy screen which will attract wildlife, require less maintenance, and demonstrate that a native garden can be just as good, if not better than a non-native one. It will require vigilance, however, as the last time I was over checking on the plants, I had to unwrap a 6 foot strand of Bittersweet that had already crept over from the neighbors’ property and  wrapped itself around one of the Amelanchiers!

The finished planting.


Although this area it was completely on the homeowner’s land and there were no neighbors to add to the mix, it seemed to me to be more complicated. To begin with, although there had been a couple larger trees taken down, the majority of the clearing seemed to be of Sumac and invasives and the trimming of old stumps to ground level.  This was difficult to be sure of in the beginning as it was late fall and the plants had gone dormant, but when spring arrived it became clear that other than one or two small trees that had been cut down, what had been  done was basically a basal pruning, (cutting the plants to ground level,) and the Sumac and the invasive species were making an enthusiastic bid to take over the area once again.

Early October, 2014 after clearing.

So now the question was, “What to do?”. The invasives should be dealt with so that whichever native species were to grow there would survive. But being only yards from the water brought up its own issues concerning how to deal with them. We were under a time deadline from the DES to complete the reparations and so we didn’t have a luxury of smothering the area with black plastic, plus we didn’t want to kill the Sumac, which is considered native in the State of Maine and was already well-established. We didn’t want to dig, thus compromising the integrity of the banking, yet for the long-term survival and success of any planting, the invasives had to go. At war was the reluctance to use herbicides (we didn’t have a pesticide license anyway, so that would have to be contracted out),  the desire to dig as little as possible, and the need to end up with a native buffer as soon as possible. Add to that the fact that a plan had to be agreed upon concerning the number of trees to be planted and how much of the past decade’s worth of clearing the homeowner was responsible for. (Despite the fact that they had owned the property for less than a year, they were responsible for replacing the whole decade’s worth, apparently.) We have a lot to decide in a short period of time.

The answer seem to be found in the saying, “We have very little time, and therefore we must proceed very slowly.” Thanks to a couple of very positive, cooperative meetings with town and state DES officials in which they allowed us to have extensions to the deadline, we ended up implementing a watch-and-wait strategy whereby we would give the plants a month or two to make a comeback and then see where we stood. When recheck time came, things were much clearer. The banking was bursting with healthy Sumac, some of it already over a foot tall. The oak tree which had been cut down was already producing suckers. Likewise, unfortunately, the Bittersweet and the Multiflora Rose were also doing well, but at least at this point we could tell our friends from our enemies. At the next meeting it was decided that a licensed pesticide applicator would be hired who knew the safest way to tackle invasives at the water’s edge, and they would carefully spray them but leave the Sumac alone. A period of time would be allowed for possible regrowth, at which time the second spraying would be done if necessary and then the situation would be assessed again. Now, I know there will be those who shudder at the thought of spraying, but the consensus was that spraying was the lesser of all evils. It resulted in the root zone of the banking being left intact, and the native plants being given room to grow and multiply, and as it was done carefully during a dry spell, there should have been no danger to the water’s ecosystem.

We flagged the good guys vs bad guys for spraying.

A month later, the Sumac was definitely winning.

Ultimately, the invasives were beaten back, and by late summer, nine months after the original clearing, the Sumac was over 6 feet tall. At our last meeting with the DES officials, it was decided that the Sumac should be allowed to grow unencumbered until the next season, at which time it could be thinned to approximately 40 plants. The sprouts of the Oak which had been cut down were also to be allowed to grow for a season, after which time one shoot would be chosen as the new leader and the rest removed. Points-wise, this was more than enough to satisfy the requirement, and so we did not need to disturb it any further with new plants, which would have had consequences to the ecology of the area not just from the digging, but also with the watering etc. that is necessary to help a new plant establish. Although the designer in me would have  loved to have created a waterside native garden, this was definitely the right thing to do.

By late summer the Sumac was going strong.

All this is just the tip of the iceberg, but I think that even the tip hold interesting points for discussion. Using native plants is easy to be on board with, as is getting rid of the invasive species that are threatening their existence. But the wetland/shoreline buffer zones are important too, so should we be getting rid of invasives at any cost in order to plant natives, at the possible expense of the fragile area that borders our waters? Here, the Venn diagrams don’t overlap as much as you might think. I think the answer is that yes, invasives must be discouraged and natives encouraged, but while being very mindful that the common area is small and that solutions must be found within that area. The price is not doing so is too great.

We were very grateful for the open-mindedness of the people that we worked with to come to the solution to this problem (two problems, really,  as there were two areas of concern.) We sorted through issues pertaining to need of plants versus laws, definitions of cutting versus clearing, and reparation versus restoration, to name a few, and in the end, kept the portion of the Maine seacoast which the laws were written to protect, protected. This is the whole point, after all. And I like to hope that in the end, the landscape ended up better than it had been when the whole story started.

Time to Force Forsythia!

The season is moving along, and we are getting close to spring. But it’s still rather inhospitable outside, so why not bring some of the garden inside, to be enjoyed where you are warm and comfortable? Like forcing Witch Hazel (see post from Feb 8th), forcing Forsythia is as simple as cutting a few branches and putting them in water in a warm room. In case you forget what Forsythia branches look like, here is a picture:


This is a picture of it blooming. Ironically, I don’t have any in my garden (thanks to friends who are willing to share theirs) so I’m not able to run out and take a picture, but this picture gives you a good idea of its shape. Look for clusters of buds, branches that are opposite one another, and  bumpy openings called lenticels on the stems and you can’t go wrong. And once you recognize it, you will recognize it forever. The arching habit of the shrub is a dead giveaway from a distance, too:


Once you have identified it, just cut off a few branches, put them in water, and wait! Soon your home will be filled with a great preview of spring.

March 2018, Plant-of-the-month



This month we are featuring Scilla siberica, or Siberian Squill (Or just Scilla), a delightful little woodland wildflower, whatever you choose to call it. It will spread, but since it goes dormant in late spring and virtually disappears, this can be a blessing rather than a curse. And as long as they aren’t planted in soil that is constantly wet, they will grow with very little help from us, which can be an advantage in our busy lives.


Personally, I find them so lovely that I can’t imagine myself being sick of them, especially since the show that they put on in the spring is just what I need after a long winter. But I’ll let you be the judge!

If you decide to grow them, buy a few bulbs in the fall and plant them in a partly sunny place in groups of 3 or 5. Or, for a more natural look, just toss them in the ground and plant them where they land.  Before long you will have a spring carpet of blue to enjoy, sometimes even in the snow.
