Hygrophila Polysperma/Difformis Questions
OK so I have a 32g and added a bunch (5 strands) of Hygrophila Polysperma, a bunch (5 strands) of Hygrophila Difformis and a bunch (you guessed it) of Hornwort to it about 60 days ago. I had to get plants that did not need a deep substrate because... well... I don't have a deep substrate. After 2 months of dealing with a "planted tank" with the plants I listed above, here is the outcome and some questions:
1) yes you can cut off the shoots or roots without hurting the plant.
2) It's common with stem plants for the lower leaves to brown and fall off as the plant gets bigger. That's mainly because the lower leaves just don't get enough light. I tend to cut off the bottom of the plant and replant it about every 4-6 weeks.
3) I threw my hornwort out for the same reason. It grew fast but I didn't know where to put it or what to do with it. I didn't even buy it. I started with a 2 inch piece that came with something else I bought at the LFS. Over time I got tired or moving it around so I no longer have it.
The "aerial" roots are normal. You can trim them if you want, but it will just sen out more. Your H. polysperma is probably having its lower leaves shaded out. The denser you plant our plants, less light makes it to their bottom leaves. when this happens a plant will drop those leaves. It requires energy from the plant to keep them healthy and if they are not getting enough light. Then it is in the plants best interest to shed them. The reverse is why the top always looks so nice.
IMO hornwort is a weed. I don't keep it.
LOL! Seems I'm slower.
i have hygrophilia in my 10 gallon tank as a background plant and love it! but i can see some of the bottom leaves browing and falling off. it only does this with me when i replant the cutting but as far as hornwort, it is a weed. Maybe try cabomba maybe? it looks about the same and theres even a red cabomba
cabomba does look similar to hornwort, but would require a little more light..........I think hornwort could grow by candlelight if given the chance.........Hornwort is a great plant to have for freshwater shrimp tanks or guppy fry tanks..........i just let it float and it still grows like crazy!
OK I've officially given up on Hornwort. It is outta here baby! More trouble than it worth. And whatever lives without roots must be a weed right? :-D
Bye bye hornwort!
