Distribution

It grows along the shores of lakes and rivers in the wild. native to Central and North America’s subtropical zones. prefers reservoirs with a slight current or stagnant water. As it rises above the water, gorgeous bright red flowers bloom on flower stalks.

Growing and care

Possesses the following attributes that have drawn the interest of aquarists:

A crucial aspect of cultivating a plant in an aquarium is that Lobelia has a prominent stem that reaches out for light. Timely picking and proper planting of young shoots in the ground are necessary to produce a lush bush. If you don’t pick and replant, the plant will appear less appealing.

The following gradation applies to the care demands:

• Light intensity

• Macro- and microfertilizers

For lobelia to fully develop, carbon dioxide and light are far more crucial than soil type, temperature, or water parameters.

Water parameters for ideal maintenance

A pH of 6 to 8 is ideal for growing purple lobelia in soft or medium-hard water. 20–26°C is the temperature indication. requires that a portion of the aquarium’s water be changed once a week. Pre-settled liquid is used for these uses.

Lighting requirements

Lobelia requires light that is at least 0.5 W/l, or fairly bright. At least ten hours of daylight. When these circumstances are satisfied, the lower leaf surface develops a stunning purple-red tint. The leaf blade actively yellows in the absence of light, which eventually causes rotting. When planting, the front and side plans are utilized.

Lobelia requires a lot of light, so the "Leiden Street" method is typically used to plant it. This method involves creating bushes out of individual plant cuttings and planting them in the ground diagonally from the front wall to the back. This produces a lovely transition and gives the plant the light it needs.

Soil requirements

The roots of lobelia are underdeveloped. Soil with fine grains is essential. Admittive roots form on the stem where leaves do not grow. Cuttings are simple to separate from the stem and bury in the surrounding soil. There are no unusual soil requirements for the plant. grows well in sand, rocks, or synthetic filler.

A gorgeous and adaptable aquatic plant, purple lobelia adds vivid color and vitality to any aquarium. This post will discuss the proper methods for cultivating and tending to purple lobelia, including the best lighting and watering practices, as well as advice on pruning and avoiding common problems. Whether you’re a novice or an experienced aquarist, knowing these essentials will help you maintain the health and beauty of your underwater environment while caring for your purple lobelia.

Fertilizers and features of their application

Nitrates and phosphates (NO3 and PO4) are macrofertilizers that provide the plant with the nitrogen and phosphorus it needs for healthy growth and foliage. These elements are crucial for feeding Lobelia after carbon.

Micronutrients: additional elements (potassium, iron, and magnesium) that are readily available in tap water. It makes no sense to apply micronutrient fertilizers when water is changed frequently.

Furthermore, an overabundance of these substances encourages the growth of active algae, a more serious issue than dormant plants.

It is necessary to feed aquarium lobelia in accordance with the directions found on the fertilizers. In the event that prerequisites (leaf rotting, yellowing, or withering) exist, fertilizers are applied in accordance with deficiencies.

Prior to applying fertilizers, make sure you have tested for carbon dioxide, nitrates, and phosphates and have read the instructions carefully. You should also accurately calculate the dosage. In an aquarium, balance is crucial, and it cannot be restored with a "magic pill."

Reproduction

Three methods exist for propagating lobelia in an aquarium:

• Cut off the side rosettes with rhizomes from the mother stem – suitable if the young bush has sufficiently formed roots and developed leaf blades.
• Pinching off the top – performed when the stem has reached 20-25 cm. Cut with scissors, after which the stem with young shoots is dug in horizontally. After 10-15 days, the remains of the stem completely rot, and the young plants take root. They can be planted or formed into dense bushes.

• Dividing the old stem – an old plant on which there are many young shoots with small roots is cut into strips so that each segment has 5-6 rosettes with young bushes. The rhizome and the lower empty part must be removed, and the resulting sections must be deepened into the soil so that the roots are completely covered. After some time, the young bushes will separate from the rest of the stem and will be ready for planting in the desired order.

Types

The most typical ones are:

Cardinal lobelia, also known as blood-red

Miniature violet lobelia

A few words from experts

No matter how easy it is to grow purple lobelia in an aquarium, problems still occur. Furthermore, they have nothing to do with inappropriate picking or neglect of the plants—rather, they stem from ignorance. Let’s examine the main ideas.

Temperature and light

Numerous studies have demonstrated how the number of lateral branches and the shape of the lobelia leaf depend on the temperature of the water. The leaf blade is more rounded and has more internodes at low temperatures (19–22°C). The temperature causes the leaf to become more twisted and elongated as it approaches 25°C. In addition, the stem gets thicker and longer. Small, squat bushes are a better option for an aquarium.

Lobelia will undoubtedly reach for its light source if there is not enough of it. The end product is a long, tall stem with few lateral branches. Should there be sufficient light and ten hours of daylight, the lower portion of the leaf will express gratitude with a deep purple-red hue.

If you do not trim the top..

As the stem gets thinner, it will shoot upward and into the air. The plant will stop being a bush and lose its pleasing appearance. All of Lobelia’s energy will go into sustaining and feeding the portion that is above water. There won’t be many lateral shoots.

You can and ought to remove the top. It can be planted to produce new bushes of plants or used to replace an existing plant by cutting off the stem and rhizome.

Fertilizers: more is better?

Acute macro- and microelement deficiencies do not affect lobelia plants. Initially, it will respond to a deficiency of carbon dioxide and light, not a shortage of nutrients in the soil.

In this case, the adage "the best is the enemy of the good" is applicable. Feeding should only be implemented when it is absolutely required, as determined by tests.

If the bushes are left without food, nothing will happen. The owner of the aquarium will have more control over when their vegetation slows down, meaning they won’t have to waste time transplanting and picking. However, what happens typically when lobelia starts to rot and become yellow? That’s correct, they add fertilizers to the soil and, most of the time, also insert nutrient tablets.

What is the outcome? If the aquarium’s owner had known what lobelia needed first, the plant would not have rotted so quickly and new issues (pathogens, algae) would not have emerged.

Reproduction

Where does the plant’s upper portion usually end up? discarded. However, there is a way to boost green mass and eliminate wasteful picking, which will facilitate the hassle-free growth of new lobelia bushes.

The order of events is as follows:

Although lobelia is not a fickle plant, its growth shouldn’t be left to chance. Any aquarium can be decorated with the help of well-timed selection and planting.

Purple lobelia’s vivid colors and distinct charm can really make your aquarium pop. Water plant aficionados love it because of its versatility. It is imperative to cultivate this plant under ideal conditions, which include consistent water quality, moderate light levels, and sporadic feeding to ensure its continued growth.

To maintain the best possible appearance, purple lobelia requires regular maintenance. In order to promote dense growth, trim it as necessary, and remove any dying leaves to stop decay. Your purple lobelia will thrive and keep enhancing the beauty of your underwater environment if you follow these easy care instructions.

In the end, purple lobelia is a fantastic option for both inexperienced and seasoned aquarium keepers due to its striking color and reasonably simple maintenance requirements. If you give it the care it requires, it will reward you with a gorgeous addition to your water garden.
