Can you add rocks to a pond?
Adding rocks to your pond is beneficial in many ways. However, rocks can be expensive and sometimes hard to obtain. In this situation, why not make your own? This article will show you how to make realistic artificial rocks for your pond.
Step 1: Gather Necessary Materials and Tools
To make this rock, I started with a small corrugated cardboard box. I use lots of cardboard, so have a good supply on hand as well. Old newspapers for filler, some chicken wire, and of course cement/concrete tools such as spreaders, trowels, buckets, access to water, cement, sand and or mortar mix, etc.
Step 2: Design and Start Construction
Thinking I could make a shape with cardboard as well, I made extensions out of cardboard that were glued onto the box with regular white glue. I let these sit over night to ensure that the glue was dried, and the bond was strong. It's sometimes easier to do these type of projects in stages, no hurry, no rush.
Step 3: Roughout "rock"
Seen in this picture is the rough rock, and the spaces in between the extensions are filled with newspaper. I even used some styrofoam as filler or extensions as well. It doesn't matter, you just want to make some support for your cement mix.
Step 4: Wrap Form With Chicken Wire
After enough newspaper and or styrofoam has been added to the "rock" form, it is all wrapped with chicken wire. I used the 2 inch size as it was cheaper, but 1 inch might be preferred. I made two layers of wire, thinking hole sizes would help hold the mortar better.
Step 6: Add Mortar Mix to Rock
Using a 3 inch spreader knife (drywall), I spread the mixture over the rock form. I started at the bottom edge of the form so that any loose mortar could be picked up and added to the rock before moving on.
Step 7: Finish the Rock
After an overnight cure, the mortar was set enough that I could fill in any missed spots, or more commonly, places where the wire was showing through. To fill in these areas, I mixed some fresh polymer tile set, colored with cement colorant in a buff tone.
Step 8: The Outdoors Rock
After finishing as described, I moved the rock out into the sunshine to further dry and "season". Note it is still on the lazy susan so that I can rotate it throughout the day.
