Have Koi & Pond Plants in the Same Pond


Koi and Pond Plants
There are 2 types of aquatic gardens, a koi garden and a water garden that is just for pond plants. If you plan to have koi in your pond, count on not having any plants. Commonly known as "water hogs", Koi are curious creatures and will eat the roots right off of floating water hyacinth and water lettuce. They will also chew the stems off of water lily right down to a nub. Although young yearlings may not harm your plants, mature koi will devastate your garden investment.

Can I have both koi and pond plants?
It is possible to have both koi and pond plants in the same garden, but it takes some planning and design. This is what the nursery at
Seaside Gardens have done, see video. On one end of the pond they have their koi. The other side of their pond has a wall made of large river rock under the water making a barrier to keep the koi away from the plants. Plants can also be grown on a floating island or on shelves at the edge of the pond. I do not recommend netting to protect the plants as the fish may become tangled in the netting.

Another way to keep koi and pond plants in the same pool...
Water Hyacinth and Water Lettuce will not hurt your koi. These plants are actually used as cattle feed in some parts of South America. I have also known some gardeners that eat water hyacinth and water lettuce. I do not recommend it, because the plants are bitter. If you want to have plants in your pond with koi, I recommend that you grow your water hyacinth and water lettuce in a Rubbermade tub. They grow quickly enough that you can replace the plants the fish will nibble on.

What do I do with the old pond plants?
The old plants are a good additive to the mulch pile and are full of absorbed nutrients from the fish excrement, also known as fish emulsion - a water hyacinth and water lettuce are natural "fish" fertilizers which is very expensive to buy!

What kinds of fish will not harm my pond plants?
Yes! The common feeder gold fish will not harm pond plants. They come in a variety of colors and grow to about 5 inches long. They will also live for about 8 years. I rarely feed my goldfish and they do just fine. With water hyacinth in the garden, your gold fish will even have babies by laying their eggs in the thick water hyacinth roots. Other fish that do well in the pond are catfish and bluegill.

How to Transplant Artichoke Plants


Artichokes often die back at least 2 times during the season and produce a new pup. They will also produce new pups when the "mother" plant is still large.
Facebook friend, Maureen asks... Hey Gail.....may I pick your brain for a second? We have several artichoke plants growing at the base of last years dead one....can I dig those up and transplant them elsewhere? Should that be done now?
Hi Maureen - I would carefully dig them up before they get too big. A good time to dig up artichoke pups is in the early spring and late fall. Dig wide around and well under as to not disturb the roots. Make sure the soil is good and wet to make it easier for removal. Plant them in a pot first with Miracle Grow soil. Water moderately. Do not soak. Keep the plants in the shade for 1 week to 10 days. Then try to move the plants out into the sun. If they tollerate the sun and the heat, then they are ready to plant into the ground.

Water Gardening in New York City

You Can Water Garden
◄ This simple pond in New York City contains white hardy water lily and papyrus plant. Pond plants are not just for a tropical environment. You will be amazed with the wide variety of plants that you can grow even if you live in a cold winter climate. If you live in New York City, you can grow a delightful water garden.

Just add sunshine and water...
Create a home oasis with the soothing sounds of bubbling water and the peaceful sight of colorful fish and blooming lilies right in the middle of New York City. Just add sunshine and water and you will have the elements needed to create your own personal pond. You can build an above ground pond either on a roof top or on a balcony. All that is needed to grow the plants are water and 6 hours of sunshine per day.

What kind of pond plants can I grow?
Pond plants are not just for a tropical environment. You will be amazed with the wide variety of plants that you can grow even if you live in a cold winter climate. New York City is located in growing zone 7. This is the same winter climate as South Lake Tahoe, California - located in Northern California at 6,000 feet. The 3 hardy plants that will grow in this climate zone are:
Hardy Water Lily, Anacharis, and Cattail. There are over 65 varieties of plants you can grow in New York City that will last through the wintertime.

All plants can be purchased from my online store or email me:

Where do I find fish if I live in the city?
Fish are absolutely necessary for mosquito control and to balance the ecosystem inside the pond. Some city and urban areas do not have pet stores. However, fish can be purchased by mail order or online. Gold fish will grow up to 6 inches. I recommend common goldfish, fancy goldfish, or the calico shebunkin. I do not recommend koi, as they will eat your plants.

No Yard Required

Ponds can be above ground or in-ground. They can be very large (like a small lake) or very small (such as a wine barrel). In New York City it can be a challenge to find gardening supplies. When pond containers, liners, and wine barrels are hard to find - a large 15 gallon plastic utility tub and even a child's hard plastic wading pool will work nicely to create a sweet water garden.

My kiddy pool pond. This hard plastic child's wading pool is overgrown with water lettuce, water hyacinth, parrot feather, and dwarf papyrus. Just add water, plants, fish, and sunshine.

How do I Care For My Pond in the Wintertime?
Plants such as water lily will go dormant during down to their tubers and roots, but they do come back in the springtime. When the weather warms back up, contact me and I will send you the best acting fertilizer you can buy. Other plants (such as water iris, primrose creeper, cattails, rush) will also go dormant and come back as the weather warms. A simple dome greenhouse or hoop house can be made to help your plants and fish through the cold season.

Hoop House
A hoop house is very easy to build with PVC pipe and 4 mil. thick plastic sheeting. An easy way to insulate a hoop house is with a layer of 1" bubble size bubble wrap in between 2 sheets of 4-6 mil. thick plastic. All supplies can be purchased at any major hardware store. If you do not have the convenience of a hardware store, the supplies can be purchased online through This type of greenhouse is good for mild climates where plants simply need to be protected from frost. A large aquarium water heater will help keep the water above freezing. Circulating the water with a pump will keep it from icing over. And stringing large C-7 or C-9 Christmas tree lights inside the hoop house will raise the air temperature by 20°.

See: How to Build a Cold Frame
A cold frame is actually a mini greenhouse built low to the ground. This cold frame is for a vegetable garden, but you can make one that will also work nicely for a container pond. Cold frames should be south facing with the top at a 40° angle. Materials used are old windows or clear Plexiglas. The advantage of the cold frame over a hoop house is that it can be heated with a conventional heater. Large Christmas tree lights also work well to raise the air temperature by 20°. This type of cold frame will work for climates with an average winter temperature of 30° Fahrenheit.

Make a Cheap Storage Closet Pond


At the end of the season, I had too many water hyacinth and water lotus. Not wanting to throw them into the mulch pile, I decided to make a new pond.


I happen to have a plastic storage closet that I was ready to chuck. This gave me an idea! I popped off the shelving and the door.


Then I filed down the rough edges from screw holes and removed any screws.


xxxI found a nice sunny place and laid the storage closet on its backside.


Then I lined the closet with 4 mil. black plastic sheeting and cut it to size.

In the process of helping my husband line the new "cheap" pond, I stepped over a pile of lumber and stepped down on a huge nail! I learned my painful lesson, DO NOT wear crocks in a construction area!



.A day and 1 hospital visit later, I hobbled out to the pond and finished the job. It looks great! All I need to do is add some goldfish or minnows for mosquito control and I'm all set. In the cold winter months, I will attach clear plastic sheeting to the fence to protect the plants from frost. I can also lower the water level and drape the sheeting right over the pond for protection.

How to Grow Water Lotus from Seed

Water Temperature
Growing water lotus from seed is easier than you might think. Water lotus seed should be started in the late springtime when the water temperature is at least 70° F warm.


STEP 1 - Where to Buy Seeds
Water Lotus seeds can be purchased on eBay. If you purchase on eBay be sure to purchase from a seller inside the United States. American seeds have a higher germination rate. Most eBay seeds come from Singapore, Thailand, Taiwan, and Hong Kong. From my experience, half of these seeds end up being duds. I call them "floaters" because that's all they do... float and then rot.

Buy American
It is possible to get FREE WATER LOTUS SEEDS from the Garden Web online. All you need to do is pay for shipping. Make sure your seller is actually a water gardener with American grown seeds. I say this, because seeds from Asia have been on the shelf for an extended period of time and their germination rate is low. Also, there is a good chance that although your seller might be from the United States that he/she could have purchased imported seeds. Contact me for more American sources for seeds:

What to look for when shopping for water lotus seeds

1. Look for the lotus "crown" in the picture if possible. This will let you know if the seller knows the difference between a water lily and a water lotus. (see pic on left)

2. If picture has a flower and leaves floating on the water surface then it is NOT a water lotus plant. It is a water "lily" plant. If the picture does not appear to be a lotus but a lily plant instead, then the seller does not know his/her plants and probably buys in bulk from Asia.

3. If the ad states that you will receive 100 seeds for a low dollar amount, then it is NOT water lotus seeds.

STEP 2 - Preparing your Water Lotus Seeds
The weather and water temperature is warm and you are ready to plant your water lotus seeds. The first thing you will need to do is to scar your seeds. This involves filing off the pointy tip of the seeds down just 1 layer. I use a large 12" metal file - which seems to work best and is the easiest method. Scarifying the lotus seed is important, because the seed will not grow otherwise and will possibly rot. After the seed has been scarred, soak the seed in a tall container of water - such as an empty clean plastic soda bottle. Change the water daily until you are ready to plant your water lotus sprout.

STEP 3 - Day 1 to 3
After the first day of soaking your water lotus seed, it can swell to almost twice the size and resemble a black olive.

STEP 4 - Day 4 to 5
On Day 4-5 you should see some green growth sprouting from your water lotus seeds! Continue to change out the water each day, but be careful as to not disturb the growth. Continue the process until your seedling is about 6 inches long.

STEP 5 - Day 12
Pick a Pot: A no-holes 3-5 gallon lily pot is the best choice. You can also use a black 3-5 gallon bucket. Black is important, because it helps to retain heat and helps to keep the seedlings warm.

STEP 6 - Planting Outdoors
By this time your water lotus seedling should be large enough to plant outdoors. You must wait until the weather outside is warm and the water temperature is at least 70°. It is possible to start water lotus seeds indoors in an aquarium located in a sunny window. Only use small minnows in the water as gold fish will eat young sprouts.

STEP 7 - Anchor the Seeds
Before planting the lotus seeds, it is a good idea to form an anchor so they will not float to the surface of the water. This is easily accomplished by wrapping regular modeling clay lightly around the seed. Do not use Play Dough. Modeling clay that does not dry out (the kind that comes in a brick) should be used. Gravel can be used over the top of the soil medium, but it is not as effective.


STEP 8 - Potting
Planting medium should be 2 parts regular clay soil mixed with 1 part river sand. Do not use concrete sand. Lotus needs little soil to grow. Allow for about 6 inches deep of loamy soil. Carefully lower the pot into shallow water no more than 18" deep. I grow mine in 6 inches of water. In cold weather zones, deeper water might be necessary for frost and freezing control.


This is how your baby water lotus will look once it is planted. The large round leaves are the lotus. The small are frogbit.

STEP 9 - Fertilize After One Season
Do not fertilize during the first year of growth. No matter how good of a fertilizer you have, this will fry the tender sprouts. There is enough in the large seed itself to sustain healthy growth for the first season of growth. During the second season, fertilize with a good quality "water lily" fertilizer tab.

This is a pic of a second season lotus that is ready to bloom. Lotus that is allowed to grow wild will grow up to 4 feet tall. This lotus is smaller, because it is potted in a small container.
