How to Care for an Anacharis Plant


Anacharis, or Brazilian waterweed, is a pond plant with pretty light to bright green leaves that resemble a fern. The plant has branching stems that are covered in groups of linear, whorled leaves. These leaves bring oxygen to the garden pond, helping to clean the water and limit algae growth. The Anacharis anchors down by the roots, but can also float freely through the garden. It provides shade to other plants and spawning material for fish. Care for an anacharis plant to keep it healthy.

Step 1

Plant Anacharis in groups for the best appearance. This will create the most prominent look. You can also keep it in small pots and place the pots along the pond bottom.

Step 2

Trim back the stems of the anacharis plant. It left alone, they can grow to lengths of 20 inches quickly. This can result in the plant blocking out sunlight. Use pruning shears to cut them down to the desired length.

Step 3

Place the part of the plant you cut off in the tank to create a second plant. Leave it floating or place the end of the anacharis about 1 inch into the gravel at the bottom of the tank. It will develop roots.

Step 4

Keep the water at temperatures between 50 and 77 degrees Fahrenheit. The plant prefers a pH level of 6.5 to 7.5., so use a pH testing kit purchased from a nursery or garden center to test the water.

Step 5

Provide anacharis with moderate light. The plant doesn't need a sunny spot, necessarily, but does best in brighter environments than full shade.
