in previous articles, you can check them out here. Build your fish pond and Cleaning your fish pond.

One of the main features of having a pond is seeing and enjoy your colorful friends as they swim gracefully by, there are plants that can help us to accomplish this. Can you imagine having a pond that is murky and blurry you won’t be able to enjoy it?

How does this all work with plants?

How does this all work with plants? I am glad that you asked. Ponds can and do collect an abundance of nutrients, when there is a buildup of nutrients algae develops when this happens pond water tends to turn from clear to murky and blurry, algae also depletes ponds oxygen and this is not good for pond life. Also, the decomposition of plants and other organic material that gets in the water can add to pond water needing to be purified.

But the good news is there are plants that can help us. These plants have the ability to feed on or absorb nutrients from the water causing water to become much more clear and clean.

  1. I don’t have a pond, nor do I have room darn it. But this was very interesting as we will be moving soon, and you never know. I would like to have more outdoor space. Right now, my backyard is literally a swimming pool with a little patch of grass. I can see me with the Iris and water lilies. They are very pretty to me anyway.

    • Hello my good friend and happy Sunday, it is so good to hear from you. Just keep those dreams alive and with some creative thinking you can have the garden or landscape of your dreams. All the best to you my dare friend and have a good day.

  2. Thanks to your post, I now have a better understanding of why algae covers ponds and what water lilies do besides looking pretty.

    There is a duck pond close to where I use to work and a colleague & I used to go down to it nearly everyday and see how the algae was steadily marching its way across the whole pond and within that you could see pockets of water lilies.

    This is a council pond and it certainly looked like it could do with a lot more water lilies to counteract the algae that was spreading quickly across it.

    I love seeing ponds in gardens and seeing lilies in them, it just makes them look so inviting, it’s also just quite relaxing looking across a pond and seeing some ducks in it as well.

    • Hello Adrian so good to see you again glad I could help, ponds are pretty amazing, all and its good to bring back old memories, all the best to you and have a good day.

  3. Hi there,

    Great post. I remember the days we had a pond in our backyard. Lots of lilies and a little bit of algae but I walked past the other day and the algae has taken over sadly.

    Thanks to your post I now understand what causes the algae and how having the plants really helps.

    Thanks for the website. Its great, Kev

  4. Plants are extremely valuable when it comes to ponds, but there are a lot of other factors as well. A small pond in full sun can be a recipe for disaster! I have tried many times with no luck of keeping mine clean. I will keep an eye out for your future posts as I am hoping to find a cure for my pond.
    Thank you!

    • Hello Nicole it is so nice to meet you, sorry to hear about your unsuccessful attempts at trying to maintain a fish pond. I will try to address and find a way that can work for you, we will keep in touch and have a good day.

  5. Hey Norman, you have a very interesting site. It appears you have covered almost every aspect of natural and organic gardening.
    I wish I had room in my yard for a fish pond. A friend has one which is quite refreshing. A cup of coffee and a good book beside a fragrant pond. That will start any day right.
    Thanks for your information,

    • Hello it is so good to meet you and thanks a million for those kind words. Having a fish pond can do wonders and add that touch of class to any landscape or garden area. I a m glad that I could help, all the best to you and have a good day.

  6. Hi. Really good info.I’ve been trying to find more plants where I live but so far have had no luck. I’m waiting for spring when the greenhouses open. I’ve got hornworth I think and oak leaf something or other I believe so far but I’d like to get java moss and other plants. I’m new at this and doing a bit of research

    • Hello Davon it is so nice to meet you, plants are just amazing and as you do your research I hope you find what you are looking for. Best of wishes to you and your garden project, have a good night.

  7. I always knew that plans where helpful to the environment, but I didn’t know that they contribute to water life as well. This is good to know when caring for your pond’s lifespan. Thank you so much for all your information on all of the plants you can use and what they provide for your pond.

    • Hello Nathan it is so good to meet you, plants is of so much benefit to us and that is what makes them so awesome. Glad that I could help, all the best to you and have a good day.

  8. Hello Norman!

    Very interesting post
    And good breakdown of all the plants that we could use to purify the water for the life in our ponds.
    My uncle is a great fan of making ponds and this information is very usefull.
    I will surely share with him !

    Thank you For this

    Wish you the best


    • Hello Santiago it is so good to meet you, plants can do wonders and they are surely of great benefit to us, I am glad that I could help and thanks for sharing this post with your uncle. All the best to you and have a good day.

  9. I don’t own a pond but I have been considering adding one to my garden and been wondering how I could have kept it clean. This is some very informative information. thank you for that!

    However, I am not quite familiar with all the plants you mentioned and you could just add some pics to assist in finding them. Thanks.

  10. Hi there,

    A very interesting article. Work with nature to purify our water for our ponds. What is the costs associated with purifying water this way? I’m guessing just the basic costs of the plants themselves and this, I might be wrong here, it’s pretty low maintenance right?

    Excellent and highly informative site. keep up the great work

    • Hello Derek it is good to hear from you, yes as far as I know it is just the cost of the plants. And they are not that hard to care off, hope this helps, all the best to you and have a good day.

  11. A fish pond sounds like such an amazing idea Norman! How hard would you say it is to actually maintain it? Also, what’s the average cost of creating a fish pond?

    I haven’t heard of creating one until now and I think it’s a very creative idea. It must be so cool to see your own environmental creation come to life. I couldn’t agree more that plants are so important for the environment we live in. Excellent post and information 🙂

  12. Hi Norman,

    I really like the idea of incorporating a fish pond and aquatic plants. I’m guessing that if you get the balance just right, the maintenance requirements will go down. It becomes a complete and self-sustaining ecosystem.

    This is giving me some inspiration should I ever have the space for a water garden area. I am contemplating ideas for “mini water gardens” that can be done in containers and even on balconies.

    Lots of great informative material. Keep up the great work!

  13. I have a small fish pond made out of a wide based flower pot. Planted some water lilies which were beautiful when it bloomed. However, the water is still a bit murky. Would you be able to advise?

    It will be great if your have the picture of the plants you mentioned.

    • Hello Sharon it is so good to meet you and I am sorry for taking so long to respond, Having a pond is so great because it adds such a touch of class to our landscape and gardens.
