How to grow and care for Rotala rotundifolia

Light

There is no doubt that any aquatic plant is phototropic. The phototaxis of Rotala Rotundifolia is also quite strong, so we can consider using phototaxis to control lodging. Not long ago, there was a shop in Handan Trade Street that opened a semi-steel Rotala rotundifolia, but almost no one stood upright. Why? The light is too bright in a tank with no other water plants, and you don't want to go back to KFC to do the temp job when you are bringing in a lot of money every day without going out. Control the light, do not make the light too high. The light control method is to raise the light after the growth of Rotala Rotundifolia is obvious.

Dense planting

In fact, the principle of dense planting and light control is the same, I will not talk about it, but the first requirement of dense planting is sufficient base fertilizer. Basal fertilizer must have, or soon will rot, and is permeable to better, or will rot. More shrimp is needed at the beginning of colonization because many of the leaves of the later plants will rot away.

Fertilizer

Rotala rotundifolia, like other green grasses, requires a lot of iron fertilizer, which synthesizes chlorophyll. And iron fertilizer is not enough, regular spraying of iron fertilizer can make him lusher, we can find the bud in the rapid growth after the head, the amount of iron fertilizer can be increased at this stage. And that's actually what it does against algae, which are a headache if there's not a lot of life, and green algae consume iron fertilizer, as does Rotala Rotundifolia.

Pruning

In fact, it is ahead, just how to play the problem, if so a few, cut it. If a lot of them are really thick, like my new 80 cylinders, get ready for the Rotala Rotundifolia and make it 1/3 as big as it is, then just cut it, and it will rot. Cut them in steps, say 30 centimeters wide, with the bottom 10 centimeters the highest, the middle 10 centimeters lower, and then lower again, so that they receive your fertilizer and light to the maximum area after cutting.

Heading

I saw a friend hit a Rotala Rotundifolia over the head in a VAT. The reason is that the head is not in the right place, the head is not all cut to the same height. There will be buds in the middle of each leaf, and the cutting point is basically about 0.5 cm above it. It is impossible not to rot, but the problem of how much is rotten. Then it will rot under the cutting point to the location of the bud.

Rotala rotundifolia propagation

Cut a couple of inches off the top of the plant and replant. New shoots will sprout from the inter-nodes on the stem left behind. If the initial plant was healthy, you can cut off the majority of the plant, leaving stems a couple of inches in height and new shoots will still sprout from there.

Even if you want a dense bush, plant stems at least half an inch apart to leave room for side-shoots. There should be enough space in the bottom layers even if you want a dense canopy at the higher levels.

The taxonomy of Rotala rotundifolia

There are about 50 species of Rotala rotundifolia, which are distributed in tropical and subtropical regions. There are 7 species in China, and they are from Southwest China to Taiwan and Northeast China.

The common Rotala Rotundifolia in the market mainly includes several major Aquatic plants such as Rotala Rotundifolia, Red Palace, and Indian Rhythmophyllus.

Rotala Rotundifolia (Green Form)

Rotala Rotundifolia is widely used in landscape construction. Its elongated leaf shape and high plasticity are very popular among landscape enthusiasts. It is important to note that Rotala Rotundifolia does not turn red or pink in the best of conditions. In the best of conditions, it is very green.

Rotala rotundifolia/small rotundifolia

The difference in morphology between Rotala rotundifolia and Rotala rotundifolia is actually easy to distinguish. The leaves of the rotundifolia are fat, thick, and oblate.

In terms of color, as the name implies, the rainbow round leaf can get different colors on the same grass. Under good conditions, the upper part will show a beautiful pink color, while the lower part will be slightly green.

This grass has only recently become popular among continental grass friends. Its gorgeous color makes it the best among the red grasses, especially among the Rotala rotundifolia, which has no Latin name.
