Although water lettuce is a popular plant for some pond and aquarium setups, there has been a spike in the number of people using water lettuce in their aquaponics setups recently too as well as some people using it for aquascapes.
This has caused an increase in the number of questions that we see relating to keeping water lettuce over the last year or so and due to there being no sign of the popularity of water lettuce going away, we wanted to cover a couple of the questions to try and help our readers.
One question that we commonly see is about aquatic plants turning yellow or more specifically, water lettuce turning yellow.
Due to seeing so many people asking about various problems causing yellow water lettuce leaves, we have decided to publish this article with the hope of being able to help as many of our readers as possible.
Is It Normal To Have Yellow Water Lettuce Leaves?
The first thing to do is work out if it is in fact normal for your water lettuce to turn yellow and the answer to this question is, unfortunately, a bit of a mixed bag.
In some cases, yes it can be perfectly normal for your water lettuce leaves to turn yellow and there isn’t necessarily anything wrong.
However, in other cases, it can be a sign that something is wrong and if your water lettuce leaves are turning yellow and you are unsure of the reason, it is always best to err on the side of caution and investigate a little further.
One of the main things to consider when working out if your water lettuce turning yellow is normal or not is the time of year.
If it is autumn or winter, then it is not uncommon for the leaves of your water lettuce to start to turn yellow as the plant enters a dormant state.
This is perfectly normal and nothing to worry about, your water lettuce will start to grow again come springtime.
So, if it is autumn or winter and your water lettuce leaves are turning yellow, don’t worry!
However, if it is not autumn or winter and your water lettuce leaves are still turning yellow, then this could be a sign that something is wrong and you will need to investigate a little further.
What Causes Water Lettuce To Turn Yellow?
There are a few different things that could cause your water lettuce to turn yellow and in this section, we are going to take a look at some of the most common reasons.
One of the most common reasons that people see their water lettuce turning yellow is a lack of nutrients, specifically a lack of iron.
Iron is an essential nutrient for aquatic plants and if they don’t have enough, it can cause them to turn yellow.
If you think that a lack of nutrients might be the reason your water lettuce is turning yellow, the best thing to do is to try and fertilize your plants.
There are a few different ways to do this but the most common is to use an iron-rich fertilizer that you can either buy from a garden center or online.
You can also try to add some iron rich plant food to your pond or aquarium if you don’t want to use a fertilizer.
Some people also find that their water lettuce starts to turn yellow after they have moved it to a new pond or aquarium.
This is because the water in the new pond or aquarium might not have enough nutrients for the plants to thrive.
If you have recently moved your water lettuce and you notice that the leaves are starting to turn yellow, the best thing to do is to try and fertilize your plants as soon as possible.
Another common reason that people see their water lettuce turning yellow is because of a lack of light.

If you think that a lack of light might be the reason your water lettuce is turning yellow, the best thing to do is to try and move your plants to an area where they will get more light.
This could mean moving them closer to a window or outside if the weather is good.
You could also try using a grow light to help your plants get the light they need.
A final reason that people might see their water lettuce turning yellow is because of too much heat.
If the water temperature is too high, it can cause the plants to turn yellow.
If you think that the water temperature might be the reason your water lettuce is turning yellow, the best thing to do is to try and lower the temperature of the water.
You can do this by adding some ice cubes to the water or by moving your plants to a cooler area of your pond or aquarium.
