Frequently Asked Questions

Do carpeting plants need CO2 to spread?Dense carpets usually need good light and often CO2 to fill in tightly. Without them, many carpet species grow taller and sparser rather than forming a mat.
How should I plant carpet plants for the best coverage?Plant small portions spaced a few centimetres apart rather than one dense clump — this encourages horizontal spreading to fill gaps naturally.
Why is my carpet growing patchy?Uneven light, uneven substrate, or algae outcompeting the plant in the early establishing weeks are the most common causes. Patience and consistent trimming usually resolve it.
Can carpeting plants grow without a true carpet effect?Yes. In lower light, many carpeting plants grow taller and looser instead of forming a tight mat, but they still grow. In a low-tech tank, expect a softer, less dense look.
