How to Plant Aquarium Grass Seeds

Reasons Why You Should Plant Aquarium Grass Seeds:

1. Fish rarely eat aquarium grass when it is planted. This gives you a lovely green underwater landscape without much effort. However, if left to grow, many species of plants become cumbersome when they have to be maintained for health or appearance.

2. It’s a great way to cover up any unsightly aquarium décor.

3. It livens up your aquarium with lush greenery.

4. It reduces algae growth by restricting light from penetrating the water surface, thus limiting excess nutrients for algae to thrive on.

5. Your fish will enjoy grazing on it if you have herbivorous fish.

6. The variety of species available makes it easy to find a plant that will fit into virtually any aquarium theme you have going on.

7. It’s very relaxing to sit by the aquarium and watch your grass sway with the gentle current from the filter or as your fish graze on its soft blades.

8. It’s a low-maintenance planted aquarium that is attractive and natural-looking.

9. It adds an exciting element to the aquarium with different grasses swaying in different directions, adding depth to your underwater landscape.

10. If you have no experience with aquatic plants, it’s a great way to start without investing too much time or effort.

10 Methods on How to Plant Aquarium Grass Seeds:

1. Floating Plant Method:

If you have a relatively new aquarium, the easiest method to plant grass seeds is to add them with your floating plants. This will allow the plants to take root without having to worry about digging up the substrate or damaging existing plant roots.

The downside of this method is that it can be difficult for some starter projects because unless you are careful, you can easily uproot your plants when attempting to plant them.

2. Planted Aquarium Method:

This method of planting grass seeds is best for those with a planted aquarium or who have a lot of previous experience planting new plants. This method also tends to yield better results because the grasses grow slightly faster than if they were planted in the substrate.

However, this method can be complicated for some people to accomplish because it requires a deep enough tank that the seedlings have room to grow into adult grasses without being up rooted or damaged by other plants or fish.

3. Soil Method:

This is one of the best methods you can use to get the most out of your aquarium grasses and have a moderately planted or even a lightly planted tank. This method also allows for some of the highest success rates.

The downside of this method is that you will need to purchase at least one bag of aquarium soil (or make your own by mixing sand with regular topsoil), and it takes a little more time to get results than if you were to use another planting method.

4. Rock or Driftwood Method:

This method of planting is an excellent way to establish a grass line in an aquarium if you already have rocks or driftwood that are not thriving plant-wise.

The downside with this method is that most people do not use it because they do not want to risk damaging their expensive aquarium décor, but it does work. This method also does not produce results as fast as some of the other planting methods.

5. Scraps Method:

This method can be used if you already have a thriving aquarium and want to add some grasses without using up valuable substrate space or costing too much money. Plant your seeds on top of any excess/unused substrate or around the base of any old/dead plants.

The downside to this method is that it can be tricky because you cannot simply plant your seeds anywhere but instead need to place them in areas where they will not get uprooted by fish or other plants.

6. Substrate Method:

This is also an excellent way to plant grass seeds if you have planted your aquarium or are trying to fill in bare patches in your substrate bed, but it can be difficult to accomplish because of the depth requirement.

The downside to this method is that most people do not have enough experience with aquatic plants or do not have large enough tanks to plant this way.

7. Bare Patch Method:

This is best for those trying to fill in bare patches of substrate or establish an even grass line without worrying about where fish or plants may move or damage your seedlings. It is also best if you already have a thriving aquarium but just want to add some grasses.

The downside of this method is that it can be difficult for many people because you need a bare patch of the substrate, and it does not have the same results as other methods, but it still works.

8. Drain Method:

This is a suitable method if you have a thriving aquarium with a lot of excess substrate space. This method can have relatively high success rates. Still, you need to keep in mind that the grasses will only grow so fast because they are limited by the amount of light and nutrients they receive through your filtration system or substrate fertilization.

9. Top Dressing Method:

This is a good method if you are trying to plant grass seeds in your aquarium, but do not want to spend the time or money that it takes using other methods. Simply place some of your aquarium soil on top of the substrate, sprinkle grass seeds evenly across the surface, and then proceed to seed as normal.

The downside to this method is that you are limited by the number of grasses you can plant, but it is still a suitable method for those just starting with aquatic plants.

10. Scatter Method:

This is a suitable method for establishing a grass line in your aquarium, but you do not want to have an even look or do not have enough substrate space.

Instead, you can scatter the seeds across the surface of your substrate bed, and they will grow into whatever direction they naturally fall, which will give you a nice random grass look.

The downside to this method is that it can be difficult for younger grasses to grow into deeper substrate beds or stay rooted in a current without a lot of weight on top of them. However, if your aquarium bed is deep enough for them to remain rooted, this method can have high success rates.


Now that you know how to plant aquarium grass seeds, so it’s time to take action. Here we have given some tips to get started.

1. Do not pour the entire contents of the seed packet into your aquarium. This will result in an overabundance of plants and may leave you with poor plant growth or straggling plants that don’t look natural.

2. Aquarium grass is best placed on the substrate to help it overgrow without frequent trimming. It also reduces the chance of uprooting the grass when you pull on it to remove any excess algae or another type of plant.

3. The key to growing aquarium grass is plenty of sunlight and good water quality, which means regular water changes and a nitrogen-rich substrate.

What Alternative Can I Use Apart From Aquarium Grass Seeds?

You can use a plastic grass mat as a substitute for aquatic grass seeds. The mats are less likely to be eaten by fish and plants will grow along with the woven blades.

If you want your aquarium plants to grow straight up, you can plant them on their edges with just the roots in the substrate. When planting flora that needs to be anchored, it is best to use the plastic mat instead.

Carefully cut holes in the grass mats so that they are slightly larger than the root system of your plants. Then, if you want, you can place several mats over each other for deeper planting zones where more oxygen will be available to plant roots.


Planting aquarium grass seeds is a great way to spruce up your tank, but it can be hard work. The most important thing you need to know about planting the seeds in an aquarium is that they require particular care and conditions for them to grow successfully.
