Moneywort is a moderately hardy stem plant that will thrive in most aquariums. It will typically grow to 12" tall, but may grow even taller under high light conditions, even continuing to grow horizontally until it reaches the water's surface. If left untrimmed, it will extend its branches out of the water.
Provide a minimum of 2 watts per gallon of full spectrum (5000°K-7000°K) lighting for the best results. Moneywort can tolerate water temperatures from 72°-82°F, but for optimum growth, the temperature should be approximately 76°F.
There are two ways to propagate the Moneywort plant. When sufficient vertical growth is observed, white roots should begin appearing at leaf nodes. When these roots are approximately one-half inch long, cut the stem 1" below the roots and insert into the substrate. The second option is to allow the Moneywort plant to grow until it has reached the surface. It will start to grow horizontally along the surface and put roots out at each leaf node. Allow these roots to grow to approximately 2" long, then cut each root section and plant in the substrate. This option is best if you wish to grow a large number of plants.
