How to Care for Rotala Rotundifolia

Rotala Rotundifolia Light Requirements

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.

Rotala Rotundifolia Planting Dense

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 for Rotala Rotundifolia

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 Rotala Rotundifolia

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.

Rotala Rotundifolia propagation

Cut a couple of inches off the top of the Rotala Rotundifolia 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.
