Is it wrong to cry over koi? Well, I did last night when I came home to the news that my husband found our prized koi (prized by us) floating on the pond. And I shed a few tears. Of all the fish we have (13) she was special.
We’d had her since 2001, one of three, 3-4″ koi fish we bought at a local pond supply. She was beautifully marked in red and white. We didn’t know at the time she was a girl – but we named her Ichiban, Japanese for ‘number one.’ She reigned supreme as the queen of the backyard.
https://delawaregardener.wordpress.com/2013/05/23/ponds/ As the koi grew, they became accustomed to our habits and movements and Ichiban was the one that always approached us at pond’s edge, let us pet her on the side and after a short amount of training, ate trustingly from our hands.
She was a show stopper and a performer. After two seasons of being well fed, she grew gregarious and had a friendly, if not curious personality.
She’d spy us and swim over, her mouth opening and closing. “Feed Me! Feed Me!” she seemed to say.
When we had to replace a pond liner a few years ago, she didn’t fight the net and calmly let us transfer her to a temporary pool – one where we could pet her with ease.
When we added a butterfly koi around 2009 or so, her behavior changed to that of a spawning female. She’d race around the pond, thrashing, side to side, and flipping in the air, sort of playing hard to get, or so it seemed to us.
We knew little of the game of koi courtship. We had a lot of plants in the pond that year. By the end of the summer, we found many new baby koi with Ichiban’s markings along with swishy, graceful butterfly tails.
We always have had to fight off predators.Southern Delaware has an abundance of waterways, but Blue Herons nevertheless found our small patch of water irresistable. In 2013, we bought a dozen or so copper shepherds hooks and placed them around the pond – this allowed a net to be stretched across the entire length and width of the pond and raised up 8 ” or so off the surface of the water.
Each year, as temperatures cooled, we watched all the fish begin to huddle together in the deepest section of our pond, about 5 feet deep, and there they’d reliably stay until the warmth of spring called them back to us.
Ichiban was always the first to feed and always the one that got the most chow.
We don’t know what happened to her. She did not seem to want to hibernate this year and came up to the surface often during the odd warm spell.
We also had our coldest winter, and like all winters in the past, we ran a warming stone that floated on the surface. We found her coming up to that several times and then go back down. She appeared confused.
Confusion, something internal, we don’t know – the snow and ice and collected leaves lowered down to the water’s surface. We’re not entirely sure, but we think she came up during a warm spell (in the 40 degrees) and the net might have stopped her from returning back down.
We found her, and one of her pretty offspring lifelessly floating together.
It is natural to love our pets and grieve over them like family. Ichiban wasn’t exactly like a cat or dog, or horse – but we had a relationship with her. Unlike the other fish, she had a personality, or we attributed one to her. For 14 years she entertained us. We had a bond. Our pond had a personality.
When my husband and I bought our three-quarter acre, pie-shaped lot in 2001 and prepared to build our house, the only thing growing were weeds! The lot was flat and boring. Over the course of 13 years, we spent most of our free time digging, sculpting, planting and readjusting our backyard. We made mistakes. We over-planted for certain and learned from our errors. As our yard evolved it soon became obvious it was atypical for our neighborhood. We were the house on the corner with a lot of trees. And I have to be honest, I wasn’t always pleased with how it looked. But something happened that made us realize we’d been landscape mavericks all along. Our unconventional residential plot embraced a new landscape aesthetic. Once we made that discovery, we applied and received certification as a wildlife habitat. In November of 2013, we received the following certificate and sign to display:
Two lectures had raised my awareness and gave me confidence that I was not the neighborhood oddball, but actually an instinctive innovator! New Master Gardener trainee classes had been going on for several weeks where I work in Georgetown. I sat in to offer tech support for a lecture taught by Dr. Sue Barton, horticulturist for the University of Delaware Cooperative Extension. Barton was teaching from the UD’s main campus in Newark and the class on Sustainable Landscaping was broadcasted live to the students in southern Delaware. The gist of the lecture? We need to reassess what is considered “beautiful” in landscaping design. Lush lawns and sculpted “just so” landscapes are pushing out native wildlife. Why not try and live in harmony with them?
Later, I sat in on another training taught by Dot Abbott, UD Extension expert on renewable resources and wildlife. Her lecture to the Master Gardener trainees illuminated the advantages of attracting wildlife into the landscape and said three things were needed to make it happen. Water, shelter and food. Most landscape designs exist to please humans. It should do that of course, but we also should be mindful of the wildlife that surrounds us and which needs our help to survive. All the while my husband and I had created a unique landscape design that had encouraged diversity. One that provided us with an endless display of sight and sound – an oasis for wildlife. We had been on the right track all along!
Our first landscape project in our new home was a pond. We had no pond experience whatsoever. We just knew that we wanted one. So in the fall of 2001 my husband hand dug a random shaped pond. He used the excavated soil to build the mound for the waterfall:
As the pond and surrounding plants matured, it became a haven for toads, bullfrogs and visits from many birds. As the pumps move the water from the pond to the waterfall, it first collects in three shallow pools which the birds especially favor. Most of the plants shown above were removed to make room for trees that partially shade the pond. In 2002 we had our first mallard couple who tried unsuccessfully to raise a clutch of eggs. A lack of vegetative shelter made the eggs easy pickings for a red fox. As the pond edge plants got bigger, mallards found it to be a safe, well-hidden nesting place and in 2013, 12 mallard ducklings took their first dip in our pond. I had a field day with my camera that afternoon!
A little tweaking and growing and our pond evolved into this:
We planted a double row of Leyland cypress on both sides of a split rail fence. Leylands are very popular evergreens in Sussex County, due in large part to their rapid growth and overall affordability, but I would not recommend them as privacy screens. Wanting instant privacy, we planted them too close and the double row was not necessary. Because they were too close, as they grew, their interiors did not develop well and the blizzard of 2010 exposed their weakness. We ended cutting down 60 percent of what we originally planted, and stacked the wood in piles along the fence. Leylands are also susceptible to bagworms. Had we to do it over again we would have used Japanese cryptomeria, which grow almost as fast, are pest resistant and in my opinion, far more attractive than Leylands. Nevertheless, any variety of evergreen will provide birds with a sheltered home in the winter, and a place to court and raise their young in the spring and summer. Other evergreens we have added are Arizona cypress (a pretty blue-green color), Deodar cedar (a graceful favorite of mine) Douglas fir, American holly, Nellie Stevens holly, and spruce.
Using our pond as a focal point, we hand dug and crafted out two garden paths which came to a point at the storage shed.
In the interior, we planted Atlas cedar, Chinese elm, white and Japanese pine, Japanese cryptomeria, (cedar) crabapple, several varieties of dogwood and red maples, and river birch. Later, we added varieties of crape myrtles. A good density of shrubs (nandina, inkberry, spireas) and trees thrived, but soon overshadowed the waterfall area! It takes effort to keep a balance between function and aesthetics.
Our pond was originally stocked with four koi. Pond plants and a net were necessary to protect them from Blue Herons which are frequent visitors. We placed a dozen small copper shepherd hooks around the perimeter and strung the net taut across the pond so it is raised off the water. This allows frogs and ducks to come and go and not get tangled. The net does not deter beneficial insects such as dragon and damselflies which eat mosquito larvae. They even rest on the copper hooks!
The standard for most residential developments has been lush green carpeted lawns, beautifully manicured ornamental shrubs, arranged perfectly to show off a feature of your house – enough of a variation to make your house a little different looking than your neighbor’s home, but pretty much each home falling into a similar formula. These were the kinds of homes that had always made me a little envious – the kind of landscapes that offer conservative curb appeal. I did not confess to my husband that I thought our yard was beginning to look unruly and overgrown. Textbook we were not!
Yet as textbook pretty as these landscapes are, they offer little for our native friends. This is a Google Earth shot of our property approximately 2004. You can see the pond (the dark blob in the center) and garden paths that wind around the pond – and the double rows of Leylands matured quickly. To the left of the main house, we reserved a rectangular area as a future vegetable garden. This is where we built a compost bin made from recycled pallets.
A few years later, you can see the substantial growth – still no vegetable garden, that came in 2012. This is from 2011:
As you can see from this second shot above, our lawn is not perfect. The only thing we apply is crab grass pre-emergent herbicide. Other weeds we remove by hand. We thinned out every other Leyland in the bottom run. In 2013 we removed every other Leyland from the top row of the V. This allows more sunlight into the main garden area, which had become very shady. We plan to fill the gaps with native plants.
To qualify your backyard for certification, you will be asked to demonstrate sources of shelter, food, and most importantly water for birds and insects. Our pond is edged with stacked rocks and many critters live in the nooks and crannies. I have encountered many a harmless garter snake while gardening without gloves! Although our pond is a major source of water, we wanted other isolated pockets where fresh rain water could be obtained. Dot Abbott suggested turning empty wine bottles upside down. Plunge the bottle’s neck into the soil – the large dimple at the base of the wine bottle is a great reservoir. Off to the wine store we go! Might be time to buy a bottle of Blue Nun just so I can get the blue bottle! Blue is my favorite accent color I use in the garden.
Place birdhouses throughout the property:
We hang a variety of birdhouses – and plan to get more. Everyone we hang is quickly occupied. We enjoy sitting on benches and watching the families come and go! I don’t know what type of bird it is, but the tiniest, most unremarkable birds that prefer our elm trees give us quite a scolding if we get too close to their man-made homestead!
And of course, bird feeders:
You don’t need a bird feeder to feed birds however! Plant native perennials and seed bearing flowers. I get a lot of my wildflower seeds from American Meadows, which has a wide variety of annuals and perennials suitable for my region. The biggest hurdle for our particular yard has been increasing shade. Admittedly we overdid the planting the first two years of home ownership. By thinning out the Leylands along the V of our yard, we hope the additional light will help with perennials. This fall I planted quite a few rows of wildflower seeds and also hand scattered several into the beds- so we will see what comes up! Stay tuned.
Not every breed of bird will use a house. Cardinals seem to prefer our cryptomerias and a large camellia shrub as nesting sites. The sturdier the tree and shelter the better. We try and provide nesting materials. Surprisingly a weather-beaten blue nylon tarp we used to cover wood became a favorite nest-building material. We have found plenty of blue fibers inside most of the tree nests! One winter I forgot to put away some planters lined with cocoa mats – the birds made quick use of them. While in the backyard, the most important gardening tool is your camera. Always bring one with you – to capture moments like this:
Let sleeping logs lie:
All of our corrective tree cutting has produced an abundance of rustic lumber. We have made neat woodpiles which serve to provide shelter, but we have let a few simply lie in place. Don’t be in a hurry to clean everything up! In nature, leaves fall and branches tumble and provide resources that wildlife appreciate.
In the back of our shed we store medium-sized branches taken down in storms or from pruning. The pile, which we call a “thicket” provides shelter for rabbits. We enjoy seeing the bunnies romp around the yard and many have safely raised young. The rabbits don’t bother our vegetable garden as we have raised beds. We have not had to use any pesticides in the garden because all the birds we have attracted to our property keep insect pest populations very low. It is all very balanced. We also have several more organized and well-disguised woodpiles, under tarps, which we tap into for evenings by a fire pit. It will take years to deplete our supply. The log piles sit upon cinder block so they are raised up from the ground. This provides additional shelter and the slow breakdown provides a level of warmth.
A diversity of trees brings a diversity of birds!
In addition to Northern Cardinals and North American Robins, we are visited by Blue Jays, Eastern Bluebirds, Northern Mockingbirds (who quickly recognize their humans) various sparrows and wrens, woodpeckers, doves, grackles (who we try to shoo away) Red-winged Blackbirds, Tit-mouses, and when we put out thistle seeds, Goldfinches. I am sure there are others – I am just learning to identify them. I hope to erect some Purple Martin birdhouses soon, as they really help cut down on the mosquito population. I am saving up for a good long -ranged telephoto lens so I can capture more pictures without being too intrusive.
Bring on the volunteers:
Because of all the birds visiting, bathing, eating and performing other bodily functions, we get our fair share of shrubs growing in locations we never planted. I try to make as many of these work into the landscape or transplant them to another area. Each spring I am treated to new surprises, and because I didn’t plant them, I do some detective work to see if I have a weed or native plant! We enjoy three unplanned butterfly bushes – and so do the butterflies!
Don’t be in a rush to rake:
Let it rain and collect it in barrels:
We have four rain barrels that we bought for a low cost through DNREC. Many Master Gardener workshops are devoted to using rain barrels and making your own from large drums or trash cans. They have an insect screen barrier on the top. Ours were old olive shipping barrels from Greece. Eventually I would like to paint something artistic on these. If you Google “rain barrel art” you will see some amazing designs! Slowly, I am trying to convert our existing design into a George Harrison-themed garden! Harrison was my favorite Beatle (didn’t we have to have a favorite?) and my admiration for him grew as I learned of his passion for gardening. Harrison was famous for his psychedelicly painted home Kinfauns, his Mini Cooper and his 1961 Fender Stratocaster “Rocky.” I hope to use some Sixties’ psychedelia as inspiration for my rain barrels!
Finally, create a place to interact with your new habitat. Every year I try to add a wooden chair or bench. Remember that movie Phenomenon with John Travolta and Kyra Sedgwick…her character made these really cool chairs from willow trees? Well, I’d love to repurpose some of our excess wood to make some rustic chairs or arbors. I want to rid our backyard of any plastic! Ugh!
Cookie cutter plots of residential paradise may be a realtor’s dream, but they push out the flora and fauna that would naturally occur otherwise. In nature, limbs fall, leaves settle, and seeds from native plants blow across the wind and re-sprout to beckon native insects and plants. It’s a beautiful cycle that can happen in your back yard! It doesn’t have to look wild to be wildlife suitable!
The Delaware Nature Society has an application and a criteria checklist to get your backyard certified as a wildlife habitat. For additional small fees you can get a nice sign to post and also register with the National Wildlife Federation. You don’t have to check the box for every single criteria, but by making simple changes – reducing the need for fertilizer, composting, recognizing the value of native plants, and providing food, water and shelter for wildlife, you demonstrate a commitment to create or preserve an environment that welcomes and sustains wildlife who are quickly running out of places to thrive! Our backyard isn’t perfect, but as our awareness rises, we adjust and reshape what we can to progress toward harmonious co-existence.
Each state in the U.S. has a county or regional Cooperative Extension office with experts who are happy to provide you with information for your particular area or interest. Within Cooperative Extension are volunteer Master Gardener experts – many who share this passion for wildlife habitats and would love to help you create a suitable environment for your yard. Also check with your local nature societies. The National Wildlife Federation has great resources on how to garden for wildlife in your region. Our goals for 2014 are to incorporate more native perennials – specifically Beebalm, Purple Coneflower, Coreospis and many others. You can look up recommended wildflowers for your state or region here.
Update (2019): I would not recommend Japanese Cryptomeria as I have discovered they are a dirty tree, dropping huge and ugly dried foliage. River birches, when they reach maturity, as one of ours have, sends out millions of seeds and pollen. Each year we pull thousands of new baby river birches out of the landscape. Please consider native trees in your landscape.
When we bought our house, it was brand new. We had .75 acres and about half of that was the pie shaped back yard. In 2002, my husband began to map out a free-form outline for a future pond, which he began digging out during the summer and fall 2001. We estimate it to be about 5,000 gallons. We didn’t have one tree or shrub in our entire yard. We had no experience with ponds – knew nothing about filtration, liners, skimmers, etc. We figured it out all on our own.
A year later we added plants and bought four koi. Three of which still survive today. Figuring they were at least a year old when we got them, they are at least 12 years old! I also got the bright idea to buy some cheap goldfish, you know, the kind you win at a church carnival? Big mistake, for all they did was eat and poop. We also bought some other fish, none of which survived the year due to Blue Herons that would visit our pond, usually at dusk and dawn. Somehow, the koi knew how to avoid being served as dinner!
Later we added more plants. The only fish that reproduced were the goldfish. Goldfish and Koi, essentially both carps, are able to breed, but their offspring are rather muddy looking and sterile. We ended up giving away as many of these fish as we could.
In 2003 or 2004 we put stone from our deck to the ponds edge, so that we could have a patio.
We also carved out garden paths to the left and the right of the pond, which converged to a point at the garden shed.
A serious leak in 2009 forced us to drain the pond completely. We bought a kiddie pool to put the fish in, and it was a good time to weed out all the mutts. My husband put them in a cooler and took them to a natural pond nearby. I couldn’t bear to kill them. With fresh water, we decided to buy two more koi (after four years we had lost a white one due to natural causes). OhNo, a pretty yellow gold koi, stayed in the pond for about two months before a Blue Heron got to him. We found him alive, but floating on his side with a puncture wound.The other koi was a butterfly or fantail, almost white with some pale orange coloring around the head. We didn’t want to lose “Choucho” too! That is when we decided to get a net. We bought copper hooks and put them around the pond and their purpose is to hold the net taught.
Once we put the net up, we also bought a lot of water hyacynths and parrots feather. That year, the vegetation just went wild. We could hardly see our fish, but the water was very clear. And something else happened, we started seeing babies! Breeding koi is difficult because they tend to eat their own roe. The combination of the net, lots of roots floating on the surface and vegetation in the pond for roe to attach, plus perhaps the addition of OhNo and Choucho (Japanese for butterfly)provided an ideal habitat to make koi babies. More than a dozen survived. We’ve given a lot away, but kept eight to enjoy. We see many of the characteristics of our original koi in this second generation. One in particular, we dubbed Rising Sun, for his nice round orange spot on the top of his head. I also like the name because it is one of my favorite George Harrison songs. He’s very shy and quick and its hard to get a picture of him.
The pond net makes getting nice photographs difficult In the spring, the net catches various seed pods and leaves, and it can get kind of junky. We’ve got to figure out a way to vacuum this debris off. But it is necessary and acceptable if it means our koi are safe!
We changed the water in the pond this year (startling a mother mallard that nested at the pond’s edge and pump) and I made my husband take out most of the plants that had overgrown their pots, and which had also accepted many weeds. He removed them under duress, but we needed a fresh look. So we launched this spring with one pickerel plant, and plan to get some more. We need the plant life to fix the nitrogen and help shade the pond. Algae is a problem, though the fish don’t mind it.
As I was taking pictures, my husband ran out to Ace Hardware to get a bag of cracked corn. We figured she was hungry. The babies nibbled at the bread I was offering, but mostly the mother consumed the bread. She must have been starving, staying close to her clutch as they began to emerge.
Here’s a video:
After about 5 hours of this incredible show, the mother mallard climbed out of the pond, with her ducklings closely following. They exited out the back yard, went through a gap in our fence and traveled to points unknown. I did some reading about mallards, and it is common that they abandon their nest, but I wasn’t sure if that meant our pond too. I guess it did. There were a couple of things that might have factored in her decision to leave. 1. Our presence. 2. Our net. This net had confused her as she would always fly in from wherever she visited to feed. She’d bounce on the net for a while before figuring out how to return to her nest. 3. The koi. She might not have appreciated sharing the pond, though I doubt she would have that privacy in nature. 4. No pond plants. She seemed to really like perching on the pickerel, but there wasn’t enough room for the duckling dozen.
I have heard that mallards will return to the location of a successful nesting, so we hope to see her again soon!
In 2002, my husband hand dug a large pond, approximately 5,000 gallons. We bought four koi, and have since enjoyed many days and nights in front of the pond. In coastal Delaware, we are often visited by Blue Herons and as a result of their many visits, we’ve had to put up a net. I purchased 3 ft tall copper hooks (about eight) and placed them around the perimeter of the ponds edge, and we suspend the net on the hooks. This allows for the net to sit up approximately 18 inches from the water, so that frogs can come and go! We drain the pond approximately every two years or so, and once, we had to replace the liner. In early April, while my husband was draining the pond and moving things around, he startled a mother Mallard duck. And she him! She squawked and dove into the water. My husband saw her nest, and counted 12 eggs!
We left her alone and on Friday, May 10, we saw her swimming in the pond and talking to her babies, encouraging each to take their first plunge in our fresh water! I’ll post more about this later!
