How To Propagate Hornwort: The Comprehensive Guide

Introduction to Hornwort

Hornwort (Ceratophyllum demersum) is a submerged aquatic plant that is native to North America and Europe. It has long, thin leaves with an olive green or dark green coloration. This species of plants are popular in aquariums due to its ability to filter water as well as providing cover and hiding spots for fish. Hornwort can grow in still or flowing bodies of water, ranging from ponds and lakes, streams, rivers and even ditches!

Propagating Hornwort

Propagating hornwort is relatively easy with the right tools — a pair of sharp scissors or pruners, a container (preferably plastic), some gravel/rocks and potsting soil mix (if you want it to be rooted). Here’s how you propagate it:

1. Cut off portions of the existing hornwort using your scissors/pruners into smaller segments about 2-3 inches long each – make sure there are at least two leaves attached per segment for better chances of propagation success; this will also help maintain more balanced growth over time.

2. Place your cuttings in the container filled with either gravel/rocks or potting soil mix; if you want root development choose the latter option but note that rooting may not occur if all the conditions aren’t just right!

3. Ensure that your propagated pieces are kept moist by submerging them in clean water – ideally, use dechlorinated tap water or aged pondwater instead so they don’t get shocked right away; keep them out of direct sunlight otherwise they could get cooked alive inside their little containers!

4. After 1-3 weeks have passed depending on environmental conditions outside such as temperature fluctuations etc., check if any roots have developed around where your cuttings were placed; this means successful propagation has occurred and can now be moved into its new home – whether it’s an aquarium tank setup or outdoor body of water like a pond etc… Congratulations! You’ve successfully propagated hornworts!


In conclusion, propagating hornworts isn’t all that difficult once you know what steps need taken care before hand – plus no specialized equipment required so anyone can do it regardless their level experience with aquascaping projects!. With proper care given towards these aquatic beauties they’ll provide much needed filtration services while adding visual appeal too – making any aquarium tank setup look attractive again after awhile thanks to their presence alone
