Are aquarium plants hard to keep? Not necessarily, but the honest answer depends on how ambitious the tank is. The source used for this guide describes hobbyists who keep plants with minimal equipment and report lush growth, and it also describes serious aquascapers who run timed lighting, carbon dioxide and fertilizer. Those are two very different jobs. This guide explains what plants need, where beginners run into trouble, and how artificial plants in a small kit change the question.
Quick answer
- Live plants need light, a place to root or attach, and some form of nutrients; the amount of effort scales with how many plants you keep and how fast you want them to grow.
- Low-tech tanks with few plants are reported by hobbyists to do well with little equipment; high-tech planted tanks add timers, CO2 and fertilizer.
- Algae is tied to excess nutrients and waste, so keeping the tank tidy matters as much as the plants themselves.
- If you want greenery without the upkeep, several small kits on this page include artificial plants.
What live plants actually need
Light. Plants use light for photosynthesis. The reference page says a planted-tank lighting system is typically run at about 2 to 4 watts per gallon (0.5 to 1 watt per litre) and controlled by a timer. It also notes that some aquarists skip artificial light and place the tank near a north- or northeast-facing window. The takeaway for a beginner is that light should be steady and predictable, which is exactly what a timer gives you.
Carbon dioxide. The same page says CO2 supplementation may be needed depending on how many plants and fish are in the tank. Options it describes range from a homemade yeast and sugar setup to a pressurized CO2 tank. It points out that pressurized tanks need periodic refilling and that yeast setups need more frequent maintenance. For a first planted tank, many people skip this layer entirely and stick with plants that do not demand it, but the source does not name which plants those are, so ask a local fish store or the plant seller what a given species requires.
Substrate. Some substrates containing laterite also provide nutrients, and in the Walstad method soil replaces aquarium gravel. If you are using a starter kit with plain gravel or sand, rooted plants will depend more on fertilizer, while plants attached to rocks or decor take what they need from the water.
Fertilizer. Serious aquascapers typically use aquarium-safe fertilizers in liquid or tablet form to help plants fill out faster. The key phrase is aquarium-safe: garden products are not made with fish in mind.
Where beginners struggle
The most common difficulty is not the plants dying, it is algae. The reference page links algae to excess nutrients and waste. Control methods it lists include water changes to lower nitrates, algae-eating fish, shrimp or snails, and balancing light, CO2 and fertilizer so plants use the nutrients available. In practice that means: do not overfeed the fish, do not leave the light on all day, and do not dose more fertilizer than the plants can use.
A second trap is adding new plants straight from a bag. The page suggests disinfecting new plants with diluted hydrogen peroxide or bleach. If you try that, follow the seller or a reliable hobby guide for exact dilution and timing, because the source does not give figures. A short quarantine in a separate container is another simple way to avoid bringing pests into the tank.
The third trap is expecting a fast result. Plants adjust to a new tank before they grow, and some may lose leaves at first. Patience and a steady routine matter more than gadgets.
Low-tech or high-tech: which one are you building?
A low-tech tank has modest light, no CO2 and perhaps a little fertilizer. It is cheaper to run and forgiving, but growth is slower and the plant list is shorter. A high-tech tank has strong timed lighting, CO2 and regular fertilizing. It can grow more demanding plants and fill out quickly, but it needs consistent attention, and mistakes show up as algae. The source does not rank plants by difficulty, so rather than guessing which species are easy, choose your tank style first and then ask the plant seller which species fit it.
If you keep a betta, planted decor also matters for the layout of the tank. Our guide to aquarium plants for a betta tank covers that angle, and the guide to freshwater LED grow lights for aquarium plants compares lighting listings if you decide to go live.
The skip-the-work option: kits with plants included
If the idea of managing light, CO2 and fertilizer sounds like more than you want, a small kit that arrives with plants, gravel and a light may be a better start. Three listings from the research fit here. Read the details, because the listing text differs on what kind of plants are included.
Ahua Walsong 2 Gallon Aquarium Starter Kit
The listing describes a complete 2 gallon desktop kit with a built-in light, a water filter pump, plants, gravel, a rock and a lid. It measures 9.84 x 5.91 x 7.09 inches with a glass body and a black glass background, and it is described as suited to small fish, shrimp or a betta. The text says it includes “plant, gravel, and rock” for a natural look but does not say whether the plant is live or artificial, so check the product images and questions before buying if that matters to you.
WURJHSONG 2.2 Gallon Glass Aquarium Kit
This glass tank is listed at 7 x 7 x 9.84 inches and holds approximately 2 to 2.2 gallons, depending on decoration space. The listing says the kit includes one waterfall filter, one aquarium light, decorative sand and stones, artificial plants and a custom lid. Artificial plants remove the light, CO2 and fertilizer question altogether. The listing also notes that the hang-on filter should be fully installed and filled with water before powering on to prevent dry-running.
WURJHSONG 1.2 Gallon Glass Aquarium Kit
The smaller sibling measures 5.91 x 5.91 x 7.87 inches and holds approximately 1 to 1.2 gallons, with the same contents: waterfall filter, light, sand and stones, artificial plants and a lid. The listing says the same dry-running note applies. It is the most compact option here; the listing names betta fish, goldfish, snails, shrimp and aquatic plants as things the tank suits, but with so little water, check that the species you want fits in a space this size and ask a vet or fish store if unsure.
Practical routine for a beginner planted tank
Pick a simple plan and repeat it. Put the light on a timer so it runs the same hours every day. Feed fish lightly so waste does not pile up. Do regular partial water changes, which the reference page lists as a way to lower nitrates and fight algae. Add fertilizer only in aquarium-safe forms, and add it gradually. Watch the tank for a few weeks before changing anything; making several adjustments at once makes it impossible to tell what worked.
Because every tank differs, treat any plant advice as a starting point. When fish look stressed or unwell, ask an aquatic vet rather than changing the plant setup in response.
FAQ
Are aquarium plants hard to keep for a beginner?
They can be easy or demanding depending on setup. The reference source notes that some hobbyists keep plants with minimal technology and report lush growth, while serious aquascapers use timed lighting, CO2 and fertilizer. Start low-tech and add gear only if you want faster growth.
Do aquarium plants need CO2?
The source says supplementation may be needed depending on the number of plants and fish. It describes yeast-sugar systems and pressurized CO2 as options. It does not say every plant needs it, so check the requirements of the specific plant you buy.
How much light do aquarium plants need?
The reference page gives 2 to 4 watts per gallon as a typical figure for lighting systems, controlled by a timer, and mentions that some keepers use a north- or northeast-facing window instead. Treat that as a general range, not a rule for every plant.
What causes algae in a planted tank?
The source links algae most often to excess nutrients and waste. Listed controls are water changes to lower nitrates, algae-eating fish, shrimp or snails, and balancing light, CO2 and fertilizer with what the plants actually use.
Are artificial plants a reasonable shortcut?
Yes, if your goal is decoration. The WURJHSONG listings describe artificial plants with a light and filter. They will not take up nutrients the way live plants do, so water changes and feeding discipline still matter.
Can I use garden fertilizer in my aquarium?
The reference source speaks of aquarium-safe fertilizers in liquid or tablet form. Use products made for aquariums and follow the label.
Bottom line
Aquarium plants are as hard or as easy as the tank you design. Keep the light consistent, keep waste low, and add complexity one step at a time. If you would rather skip the learning curve, choose a kit with artificial plants and enjoy the tank first.
