Keeping Pond Weeds in Check With Spring Around the Corner!

— Written By

I don’t know about you, but I am definitely ready for the weather to warm up and to get a reprieve from the rain for a little bit. One thing to keep in mind as the weather starts transitioning into spring is that pond weeds are going to start showing up as the weather warms up. So here are a few things to think about if you have a weed problem in your ponds!

  • An Ounce of Prevention, is Worth a Pound of Cure!

If you have a pond weed problem, then you likely know it, but depending on the weed, the times that they show up may vary. I like to suggest to people to consider adding a pond dye to your pond. While some like it for the aesthetic value, it does serve a purpose with postponing weed growth in your pond. The dye works on concentration in the water and in essence shades out weeds before they start growing towards the sunlight as the water temperature in your pond starts to rise. If you know that you have a problem, then I recommend in the next few weeks that you start adding a pond dye to your pond to start shading the weeds before they get going. One key thing to remember about pond dyes is that since they work on concentration you will have to add more if additional water dilutes it out. This is a common issue that people will have; they put the pond dye in and over time it gets diluted, so the flush of weeds comes, but it is a little later than it typically would be.

  • Make Sure That It’s Identified Correctly!

Another thing that always seems to happen as pond weeds start showing themselves on the pond is people will incorrectly identify them and then use the wrong product or technique to treat for the problem. There are so many weeds out there, and for some the subtle difference means a different type of treatment. So unless you are one hundred percent sure about what the weed is, it’s always better to make sure so that you aren’t wasting money! Please feel free to take some pictures and send them to me by email to dcdabbs@ncsu.edu. You can also pull a sample and bring it here to the office, and I will tell you what the weeds are and what is going to be the most economical option to try treat them.
