The leaves comprise a pretty prominent mid-vein and secondary veins running alongside the margin.
Amazon Sword is a relatively easy plant to manage. It does well both as a background and mid-ground plant in planted aquariums.
While placing Amazon Sword in planted tanks, don’t forget to keep gravel at least 3 inches deep. They need plenty of gravel to root and it’s better to pack the gravel moderately.
Another essential thing to know is their extensive root systems. The plant can grow on its own. Hence, avoid planting the plant roots too deep so that you don’t have to do frequent trimmings.
As far as lighting goes, exposure to bright lighting or access to low is never an issue. They can withstand different lighting conditions and a variety of water temperatures.
Propagation
Amazon Sword can be grown in two ways. One is through developing small blossoms, and the other is through producing runners.
8. Anacharis
Excellent as a food source and sucks up nutrients in an aquarium. One of the easiest freshwater plants to care for
- Scientific Name: Egeria densa
- Skill Level: Easy
- Size: 6 to 8 inches
- Lighting: Moderate to high, 100-250 PAR (Umols)
- pH: 7.0 – 8.0
- Growth Rate: Fast
- CO2 Requirement: No
Anacharis is a large aquarium plant that can grow fairly well in gravel. Aquarium plants that grow up to 6 feet can be slightly demanding to place, but consider the benefits this specific plant can bring to your home aquarium.
These plants feature extensive green stems and grow in the substrate as well as floating plants.
When you observe the pattern of the leaves, you see them arranged compactly like a coil.
You have to make water parameters consistent with Anacharis since these plants grow a beautiful deep green color when kept in an ideal environment. Plants that are kept in different conditions might look light green in appearance.
When it comes to the root system, Anacharis have two different types of roots which are white. Both roots can grow from the stem and then into the substrate. The longer stems grow into the water but these stems don’t grow from the bottom of the stem. Rather, they project along the stem.
Longer stems can absorb nutrients from the water column, and make these plants a pretty fast species to grow.
Including gauging the right water parameters, you have to keep these plants in moderate lighting so that this fast-growing plant can take on a deep green shade.
Propagation
To propagate Anacharis, cut the stems that are at least 5 inches long and then insert them into the substrate.
9. Dwarf Hairgrass
Dwarf hairgrass is an easy to grow carpet that is great for beginners. Purchase tissue culture plants to ensure pest free plants!
- Scientific Name: Eleocharis acicularis
- Skill Level: Easy
- Size: 6 inches
- Lighting: Low, 35-50 PAR (Umols)
- pH: 6.5 – 7.5
- Growth Rate: Fast
- CO2 Requirement: Yes
Dwarf Hairgrass is not a new plant in the aquarium hobby. With its striking green color and beautifully shaped leaves, this plant is irresistible.
Since you’re looking for plants that grow in gravel, compromising on the appearance of the bottom is not possible. And that’s why I added this species to the list. Dwarf Hairgrass gives a soft and lush green texture to the foot of the bottom. This carpeting plant has lightly twisted leaves with blades that make it more appealing.
Like Anacharis, Dwarf Hairgrass has to be kept in proper water conditions so that it can grow to the fullest. Water conditions will also determine whether or not your plant will produce white roots. Even though these roots stay hidden in the substrate, the plant will grow to the glass of the tank and will look incredible.
You can use these plants to create a thick lawn in your aquarium. When planted properly, these plants tend to spread widely by runners.
Lighting is another contributing factor in their proper growth. In their natural habitat, Dwarf Hairgrass grows in moderate natural lighting. You will only get a beautiful carpet once you get a stronger lighting setup. Also, the intensity of light should be in consideration since this is a slow-growing plant. For the substrate, gravel or sand is not an issue, but it’s better to get something finer. Normal gravel will also do but sand is ideal for the frail roots of the plant.
Propagation
Propagating Dwarf Hairgrass is also pretty easy. Just grab the roots using tweezers and make small clumps. Place each gently into the substrate an inch apart.
10. Christmas Moss
A easy to care ground cover plant that is an excellent choice for shrimp tanks
- Scientific Name: Vesicularia montagnei
- Skill Level: Easy
- Size: 4 inches
- Lighting:
- pH: 5.0 – 7.5
- Growth Rate: Moderate
- CO2 Requirement: Yes
The last plant on this list is Christmas Moss which is beginner-friendly and is used around the world by beginners, intermediate-level aquarists, and fish keepers who are fairly experienced.
Christmas Moss grows slowly, but it can create a magnificent carpet across your aquarium. With its long and dangling branches that overlap each other, the plant resembles a Christmas tree.
Unlike other aquarium mosses, Christmas Moss is the most beautiful moss you will ever see. It’s hardy and can grow in aquariums if you keep water parameters and the overall aquarium environment matching its natural habitat.
When placing it, don’t let the plant get covered with any shade since it grows well only when there’s enough light.
The plant can grow with or without CO2, but using liquid fertilizer is highly recommended.
Propagation
To propagate Christmas Moss, take the parent plant and cut it into small pieces. After the division, simply attach the new pieces to the new site.
How To Grow Plants In Gravel Substrate
Growing and keeping aquarium plants in gravel need a little bit of proper guidance, patience and focus. In this part of the article, I’m gonna show you how to successfully grow plants in gravel. So, let’s dive straight into that. If you want to see a video breaking down the subject, check out the video below from Palmer Fish Talk.
There are three routes to grow plants in gravel substrate. The first one is putting organic soil so that the plants can absorb nutrients from it. The second one is using those plants that are hardy like the ones I discussed above. And the third route is to use root tabs.
Some people don’t like to use pots in their aquariums, and they prefer using sand. Sand is a good option to consider but gravel isn’t any less either. In fact, if you use thick sand, it can prevent water flow and encourage substrate compaction.
A proper amount of water should always flow through the substrate to ensure the plant roots are getting enough oxygen and CO2. Even if you use fertilizers, it might be hard for them to get to the roots and provide nutrients to the plants.
Before you venture out and purchase gravel, make sure you get fine gravel that won’t be harsh on the roots.
Now let’s focus on the root tabs route. The root tab route is basically a pretty easy method. All you have to do is get these little gel capsules and dip them into the substrate.
Tropica Root Tabs are superior to many store brand root tabs like API. Roots tabs created for the professional aquascaper!
Root tabs are filled with nutrients that help the plants grow and survive. They are usually filled with potassium, iron, and sometimes just dirt. Plants love dirt because they get nutrients and a system of water through it. The best way to dip these capsules into gravel is to get tweezers or use your hands. Just put them below the surface but avoid going too deep.
Fertilization
For plants that grow in gravel, fertilization becomes important more than ever. Some plants can get nutrients from fish waste but sometimes that’s just not enough.
You need to get them good fertilizers to fulfill their basic demands.

Gravel can provide them with beneficial bacteria that help keep a biological balance within the tank. The plants usually absorb nutrients from the gravel while some plants access nutrients present in the water column.
Trimming
Most stem plants grow really fast. Such plants have to get frequent trimmings so that they don’t consume the whole aquarium. Also, you have to keep your plants clean and in shape which is possible by trimming them.
While cutting off bits of plants, make sure you use high-quality aqua-scaping scissors.
Tank Maintenance
Tank maintenance holds intrinsic value to the overall fitness of your plants.
There are many issues related to plants that can influence your aquarium environment. For example, if a plant melts, or there is plant material sitting at the bottom for too long, the water can become toxic for your fish. It can even kill your plants.
Apart from keeping water parameters consistent, make regular water changes and clean the tank.
Filtration And Water Quality
When you have live plants, as well as fish living in an aquarium, filtering out toxins from the water becomes extremely essential and unavoidable.
Not only a fish tank, but a planted tank also needs a quality filtration system. For a planted tank, you can go for a canister filter to weed out toxins from the tank.
Tank Mates
For a planted tank, you have to be careful while choosing what fish species the plants are going to be with.
Here are a few fish species you should avoid housing with plants in freshwater fish tanks. While you can keep plants with them it’s a challenge.
FAQs
Can Plants Grow In Rocks?
You can grow aquarium plants in gravel, given you take care of their basic needs to grow and thrive. While some plants are ideal for gravel substrate, some species can’t withstand gravel. You need to choose those species that are hardy and can absorb nutrients from the gravel.
While some plants are ideal for gravel substrate, some species can’t withstand gravel. You need to choose those species that are hardy and can absorb nutrients from the gravel.
Do They Grow Better In Sand Or Gravel?
Growing plants in the sand is common but it can hold back water flow that is necessary for the plants. Gravel doesn’t do that. But generally, both mediums are good for plants to grow. But since each has a few drawbacks when it comes to providing plants with proper nutrients, you need capsules filled with nutrients to help the plants grow properly.
Which Tank Gravel Is Best?
Choosing the right aquarium gravel is one of the best things you can do. Whatever gravel you go for, make sure it doesn’t have sharp ends or dust but access plant roots to grow.
Some plants have delicate roots that rough gravel can irritate. Also, the shape and size, and texture of the gravel should be even.
Closing Thoughts
Many people think that they can only grow plants in soil, but there are actually many plants that can thrive in gravel. These types of plants are typically water column feeders and are easy to grow. If you’re looking for a new type of plant to try growing, consider one that can prosper in gravel. Do you have any experience growing plants in gravel? Let us know in the comments below!
