The genus was named by the famous Swedish taxonomist and botanist, Carl Linnaeus after Christian Gottlieb Ludwig (1709 – 1773), a German botanist.

Interesting facts: Ludwigia is the only genus that has existed for at least 50 million years based on the fossil pollen record.

The living environment of Diep Tai Hong La Kim

Diep Tai Hong Lam Kim grows in swamps, ponds and ditches in the Southeastern United States, common in South Carolina, Florida, and Georgia. Coniferous Ludwigia can overgrow and grow in swamps and wetlands under optimal conditions. 

They grow on land and in water, making them excellent aquatic plants.

The description of Diep Tai Hong La Kim

Care instructions for coniferous Ludwigia (Ludwigia Arcuate) - Growing, growing and propagation - description

Diep Tai Hong Leaf Kim is a beautiful flowering plant. This plant is fragile and has green to reddish shoots with narrow, pointed needles that vary from green, orange to red.

Plants do not have the habit of fast growth. It grows quite slowly to moderately and can reach a maximum height of 50 cm. It is therefore well suited for mid- or background placement in planter tanks, but can be used in the background if properly trimmed.

Diep Tai Hong Leaf Kim has many different looks depending on how it is grown.

Diep Tai Hong Leaf Kim (growing on the ground) has wide branches and can be lying on its side or lying flat. The leaves of the Diep Tai Hong needle tree are usually green in color. In addition, leaves have another form in aerial conditions, they are round in shape.

Because it is a flowering plant, Diep Tai Hong Lam Kim has beautiful small flowers with bright yellow petals that are very eye-catching.

The dry form of Diep Tai Hong La Kim is quite resilient and sturdy.

Meanwhile, plants that grow under water have the habit of growing and growing upwards. The leaves are needle- or spear-shaped 2.5–4 cm wide and 4 mm wide and green to orange-red or reddish-brown in color. In addition, the foliage is longer and narrower.

The leaves grow along the length of the stem, arranged in opposite pairs. If properly pruned, they can branch out and provide a bushy sub-layer for the aquarium.

Diep Tai Hong Lam Kim's submerged form is not as sturdy as its shallow form.

Tank requirements and water conditions

Diep Tai Hong Laminum is not one of the plants suitable for aquarists who are just starting out, and this is because it has some specific requirements that can be difficult to achieve without knowledge. fit.

Tank Size:

Ideally a ~40 L tank is enough to grow a few clusters of Diep Tai Hong La Kim.

Although this is a fairly tall plant, it can still be recommended even in small tanks because of its slow growth rate.

Water type, temperature, hardness and pH:

Temperature : The optimal temperature is from 20 – 28 ° C. Diep Tai Hong Lam Kim does not like cold water and is easy to wash. At the same time, temperatures that are too warm make the leaves smaller.

Interesting facts: The change of culture temperature had the most obvious effect on the shape of sunken leaves in Diep Tai Hong La Kim. Submerged leaves formed at 23°C are clearly narrower in shape than submerged leaves formed at 31°C.

Attention: According to the same experiments, light intensity and pH did not affect the shape of sunken leaves.

Stiffness : Diep Tai Hong Leaf Kim can grow well in both hard and soft water. However, it is best to consider soft to moderately hard water in your aquarium.

PH : Make sure to monitor the pH of the aquarium water. Basically, a pH of 5.5 – 7.5 is suitable for this species.

The light: 

As you read earlier, Good lighting is absolutely essential for the development of Diep Tai Hong La Kim. This plant is not a good choice for low-tech tanks.

Therefore, make sure to provide medium to high illumination with higher PAR values as it helps to produce deep red color and bushy shoot growth.

In addition, maintain a standard optical cycle of at least 10 hours per day.

Note : Leaves of this species need full light to maintain best color. Their leaves are redder with high light intensity while remaining green in dimly lit environments.


Abundant nutrients in the medium help preserve the color of the stem, lower leaves and leaf tips.

Therefore, a nutrient-rich background (like ADA Amazonia, etc.) will be the best choice.

CO2 and fertilization:

CO2 : The addition of CO2 is highly recommended, it is difficult to grow this plant without CO2.

Importance : You need to understand that tall light-loving plants must be balanced in terms of CO2 and nutrients. Otherwise you will have algae everywhere.

Fertilization : This species is also intensely colored with low nitrate (nitrate limit, at least below 20 ppm).

The problem is that high levels of CO2 and Copper (most fertilizers contain copper) are extremely dangerous for shrimp.

Taking care of Diep Tai Hong La Kim

Like all living aquatic plants, it is important to properly care for Diep Tai Hong Lam Kim. Here are some essentials you should know:

  • Additional . This plant needs additional CO2 to thrive.
  • Speed Growth: This plant is slow to medium growing. You can speed up growth in the aquarium by using CO2 and plant fertilizers, helping it to grow full and dense.
  • Mineral . Diep Tai Hong Lam Kim does not require high levels of iron in the aquarium to produce deep red stems. It's all about light!
  • Cut . In addition, the plant tends to be overgrown and bushy. Pruning overgrown branches and trunks not only helps prevent the tree from becoming overgrown, pruning also adds to its beauty by keeping the tree compact and in shape.
  • Water exchange . Note that drastic changes to the aquarium can harm the plants. Make sure to make the necessary changes gradually. That way, the plant stays healthy in the new water environment. Water changes need to be done regularly. This activity ensures clean water and also helps limit nitrates in the aquarium.

One great thing about this plant is its movement with the water of the aquarium, which is a fascinating sight to behold.

Planting and propagating Diep Tai Hong La Kim

Growing Diep Tai Hong Lam Kim is quite easy:

  • Take the bundle and separate the branches gently.
  • Next, plant in groups of two or three stems in a medium that is rich in nutrients and provides bright light to promote healthy shoots.

Note : Diep Tai Hong Kim can also grow roots in the air. So you can cut this part of the plant above the node and plug it into a growing medium.

After a while, you will need to prune the plant so that it does not overgrow in the tank. Just cut the tops of the plants, i.e. a few inches from their current height, and remove them. Pruning helps promote the formation of side shoots, thus creating a bushy look.

To propagate Diep Tai Hong Lam Kim, take sizable cuttings from the trunks of several plants and place them in aquarium media.

Issues related to the development of Diep Tai Hong La Kim

Rot : It can occur in the stem after transferring matter from a terrestrial to a submerged environment. However, there is no reason to worry.

During this period, plants grown in terrestrial conditions will die and shed some leaves. After a while, Diep Tai Hong Lam Kim will adapt to the new conditions and then, grow new leaves.

Solution: Wait and the tree will grow back.

Not red: Aquarists buy this plant because it looks red but unfortunately in many cases they are not able to get this color and Diep Tai Hong Laminum remains green or just turns slightly orange. .

Importance : Excess iron will not make your Golden Leaf Diep Tai red no matter how much you put it in.

Solution: There are many debates without a confirmed answer. By far the best recommendation is to get the right conditions: soft water, nutrient-rich substrate, strong light, CO2 and low nitrate .

Extremely slow growth rate : As I said earlier, Diep Tai Hong Lam Kim is a moderately slow growing plant. However, there are cases where the plant has a much slower growth rate due to factors such as insufficient nutrients and insufficient light.

Solution: Growing in such conditions can cause Diep Tai Hong Lam Kim to deviate from its normal growth rate. But improving the identified conditions will help restore the plant's vitality effectively and by prolonging its growth rate. This species needs enough light for maximum growth.

Discoloration : Even if your Coniferous Leaf leaves are reddish, green, or sepia, there is a chance that they are pale in color. Changes in color can be caused by a lack of iron or other essential nutrients needed for optimal health and growth.

Solution: Therefore, you should dose liquid plant fertilizer in your aquarium water regularly to maintain a good supply of nutrients for your live plants.

Sick : Diep Tai Hong Lam Kim grows susceptible to clinging organisms such as pond snails, slugs, filamentous algae and other known hitchhikers.

Solution: Be sure to perform an initial disinfection or quarantine procedure before growing the plants in your freshwater aquarium. Failure to do so will result in the transfer of problematic organisms to your aquarium and that certainly won't end well.

Deformation : The lower parts of the stem and some leaves may shrink slightly.

Solution: The deformity in Diep Tai Hong La Kim is often caused by unstable (or insufficient) CO2 levels and insufficient nutrients. You need to fix this.
