Co-existing with Nature

There is a conflict between nature and designed human space.  We like to have our nature neatened up and easily readable with beautiful plants arranged just so.  Nature is just do what it needs to survive, with each of its members seeking out their basic needs: food, shelter and reproduction.  Conflict arises when our focal plantings become a meal or natures breeding habitat becomes a lawn.

In putting in our new garden and new plantings I have been trying to work with nature to achieve my design goals and keep our vegetables ‘safe’ without destroying too much habitat or employing chemical weaponry. 

The double fence has been keeping the deer at bay.  The outer border has been planted with seedlings of
pollinator-friendly perennials.  I may not get too many flowers this year as these plants get established.

To help control garden insects I have left some meadow areas intact that provide habitat for predatory insects.  I have also planted a border around the garden with pollinator friendly plants.  In selecting these plants I chose ones that are listed as deer-resistant.  To combat the beetle population I have a jug of soapy water.  This works well on some of the bugs whose escape strategy is to drop to the ground.  I just hold the jug under them and they drop in when nudged.

Here are some photos of predatory insects that are in the yard.  In addition to these I have seen the 6-spotted Tiger Beetle, very cool!
This nymph of a Wheel Bug looks like something from
the movie, Starship Troopers.
This 2-inch mantid was hopping from stem to stem in a patch of
moss phlox as I was looking for a Tiger Beetle.

Compared to the green sweat flies, Long-legged flies are aptly named.  
This 1/2 inch fly is a general insect predator.



Most of the landscape plantings I have selected are not deer favorites.  For those plants that are on the deer’s menu I have been using repellents that are either scent-based (putrescent eggs) or taste-based (capsaicin/hot pepper).  The hot pepper spray seems to be effective at getting the deer or rabbits to stop feeding on a plant even after they have gotten a first taste. 

You can tell deer damage by the ragged edges they leave where they tear off leaves and stems (deer don't have upper incisors).  Rabbits have sharp teeth and will leave a clean cut, or they will consume a plant right to the ground.  

The following are lists of plants that have I have put in that are 1, deer candy; 2, occasionally browsed; 3, not bothered by deer.  It is still early in the season and these comments are based on how they treat the foliage.  Flowers will be another subject (see some comments).  While it is risky to proclaim a plant to be deer proof, I have not seen any damage to the plants on this list (yet).

The buds on this Magnolia were being eaten off
until I put on the chicken wire cage 
1.  Heavily Browsed
Apios americana 
Helianthus tuberosus 
Magnolia virginiana 
Rudbekia triloba 
Campanulastrum americanum* 
Zizia aurea

*These were very small and eaten to the ground so rabbits or some other critters were responsible for this damage. 

The pinnate leaves of the ground nut have been
chewed off in more exposed locations


This Jerusalem Artichoke was being browsed to the ground until the fences went up.
Now (June 27) these are 6-7 feet tall.



This Filipendula was nearly ready to bloom when the deer
ate off most of the upper growth.  Note the rough edge
where the deer ripped off the tip of the plant.

2.  Occasionally Browsed
Achillea millefolium (flowers were removed, the foliage was left behind)
Aronia melanocarpa 
Hibiscus moscheutos (just once)
Filipendula rubra (just once leaves and flower buds, not after hot pepper spray) 
Lobelia siphilitica 
Physostegia virginiana 
This Hibiscus had the tips chewed off, but no more
damage since I applied some hot pepper spray.
Rudbeckia hirta 

(The Lobelia had been untouched until yesterday.)













3.  Resistant, so far
Aquilegia canadensis 
Asclepias tuberosa 
Asclepias incarnata 
Ceoanthus americanus 
Chamaecrista fasciculata  
Chelone glabra 
Dicentra eximia 
Hedeoma pulegiodes 
Iris versicolor 
Monarda didyma 
Monarda fistulosa 
Monarda punctata 
Spiraea alba 



As far as keeping the critters out of the garden, the double fence method is still working.  I’ve been able to harvest snap peas, lettuce, chard and collards, so far.

I did notice some evidence of moles digging around the property.  For these I put down a perimeter treatment of MoleMax, a castor oil based product that moles and other burrowing species do not like.

Starting a New Vegetable Garden

When we moved into our home in Watertown, MA starting a garden was easy.  The previous owner had established raised beds in a sunny opening in the back and along the south-side of the house.  The beds were small, but the soil was great.  Over the next 17 years the sunny spot in the back became only partly sunny (maybe 4-6 hours of full sun) due to the trees growing up and out.  Now with our new property in Maryland we are starting with a clean slate.  There are no established kitchen garden beds, so we need to determine which space works the best for us.

In selecting the site for the garden we considered accessibility to the garden, water, exposure, soil quality and protection from wildlife.  I consider solar exposure and soil quality as the most important factors; those are the most difficult to change.  All the convenient locations near the kitchen have less than optimal solar exposure.  A location off the garage offers better protection from wildlife, but it impinges on the septic field and is surrounded by trees (too much shade).

Garden site looking to the NNW.  Parts of the electric fence can be seen
The site I am considering with now is fairly open, with evergreens to the north and only a couple of trees nearby.  It has an open south-east aspect (the topography tilts to the SE), so it should warm-up quickly in the mornings and have good light throughout the day.  There is a water faucet nearby and the previous owners had installed an electric fence around the area, so we have the beginnings of an enclosure to keep the deer out.  I just need to take some soil samples for analysis to learn about any problems with the soil chemistry (crazy pH or nutrient deficiencies).

In addition to a deer fence I will surround the immediate area of the garden with a low mesh fence dug 6" into the ground to discourage the rabbits and ground hogs.  I have ordered a quantity of False Pennyroyal seeds (Hedeoma pulegioides) to plant on the perimeter.  The strongly aromatic scent is reported to repel many animals; we'll see just how effective it is.  Some other deer resistant plants planned for the perimeter are: Aquilegia canadensis, Asclepias tuberosa, Monarda fistulosa and Rudbeckia hirta.  These plants should also help in attracting pollinators.

Since I am planting a garden from scratch, I spent a little time reading about companion planting in order to make some better decisions about which plants will benefit from interplanting in the same part of the bed.  Two books that I found useful for this are "Companion Planting," by Bob Flowerdew and "Little House in the Suburbs," by Deanna Caswell and Daisy Siskin.  I can not speak about the benefits of companion planting yet, but these books did offer some explanation for some of my past vegetable garden failures such as Kohlrabi with Pole Beans and Snap Peas with Tomatoes.

Since I am interested in growing Native Edibles as well as 'regular' vegetables, I have ordered some tubers of Jerusalem Artichoke, Helianthus tuberosa, known as a Sunchoke in culinary circles.  These can get out of control on their own, so we will need to harvest the tubers annually to keep them in check.

I have also ordered some tubers of Groundnut, Apios americana.  They can be used like potatoes, but have a nutty flavor.  These sprawling vines may find their home along the shady woodland edge, rather than the center of the garden, for both cultural as well as aesthetic reasons.

To prepare the planting beds I will be using techniques described in Lee Reich's book "Weedless Gardening."  This is a top down method where the existing plants are cut to the ground then covered with multiple layers of paper.  NO DIGGING!  After wetting the paper it is covered with several inches of weed-free material.  In my case this will be soil that I will plant seed directly into.  For the garden paths I will use cardboard cover with wood mulch as a more resistant barrier layer.  The existing plants are smothered and since the soil was not turned over no new weeds from the seed bank are brought to the surface.  I will refer you to this easy reading book to get the details.

I've seen this technique work successfully for converting lawns to ground cover beds.  This will be the first time I've tried it over a more robust planting.  Since we still have loads of paper and cardboard left over from our move this is a perfect way to use existing resources.  The only materials I will need to bring on site are a couple of yards of planting soil and some organic fertilizer.  The best part of this method is that I will not need to turn over a large mass of the soil, only to be followed by a long season of weeding.

I will update this information as the garden installation moves along.
