Comments (2)Larry and Lisa there is a link below that may interest you. At the bottom of the linked thread, there are more links to facts about true watercress and the cress family in general. "Horton" Here is a link that might be useful: About cress...See MoreWatercress
Comments (30)johnkr, never tried a sponge but imagine it would do well. After starting my seeds in a moist soil medium, I tossed a few onto a [half-completed] coir frog island. The seeds sprouted a bit later than those in the soil but seem healthy. Once they hit 1/4 to 1/2", they appear to be in limbo, lol, as I mentioned above. I can only surmise it's the heat factor here in zone 8 based on others' comments. Time will tell. This is my first yr attempting watercress and I did get a rather late start this yr due to my mom's passing, so... Thinking if I got an earlier start my results might be different. Making a mental note (ha!) to report back after things cool off a bit here. 'Course if my watercress takes off, I won't need a reminder...I'll be jumpin' for joy, lol, and running here to report my success =] happy ponding!...See MoreGotta love that watercress..............................
Comments (7)Awww.....what a sight to come home to. Glad it turned out OK. After I read this I had a dream in which my pond drained overnight. lol Growing Watercress isn't hard but the plant can be contrary sometimes or some seasons. From my observations Watercress will do the best in part shade with visibly moving water. It will do great in full sun if by a waterfall until the temps get into the 90's in which it will seem to become submerged under the water. The worst growing condition I have seen is in water without very much movement. I really think water movement is the key when growing it. Hope that helps.

Comments (6)While upland cress is more "top-growing", watercress has leaf pairs that grow opposing each other continuously up a hollow stem. At each leaf node on either side of the stem is a tiny root hair waiting to sense the presence of water. When it does, it begins to grow and can reach a length of over 10" or 25cm. Dozens of these root hairs can grow from a single watercress stem. Upland cress does not exhibit these root hairs. It is these hairs that make watercress an exceptional aquaponic plant. The cilliated root hairs mechanically filter solids from the water while offering thousands of square inches of surface area to harbor bacteria that consume ammonia to excrete nitrite and a second type that consumes this nitrite to excrete nitrate. This process both removes the ammonia from the fish waste and supplies nitrogen to the watercress to promote growth. We, the benefactors, enjoy both the fish and the watercress... all in a day's work for nature. :-)...See More- 9 years ago
