Removal of Lava Rock Mulch

By Jeyra
March 10, 2015

The home we purchased six years ago came with extensive landscaping, complete with lava rock mulch. We wanted to replace the lava rock mulch with something more biodegradable that would break down and add nutrients to the soil as it decomposed over time. However, the thought of digging out all the lava rocks that had become deeply embedded into the soil over the years seemed a formidable task.

My hubby made a wooden frame for the screen I use for sifting compost, etc. It fits over the wheelbarrow, convenient when the soil needs to be moved, and much easier than carrying it in buckets. I have one with 1/4 inch screen, and one with half inch.
Of all the things I've lost, I miss my mind the most.

The hardest part of making a screen box now is finding 1/2" x 1/2" screen that is strong enough. I solved that by using a heavier weight 1/2" x 1" stapled to the outside of the frame. I then tie the 1/2" x1/2" screen to the heavier screen on the inside. Every few years I have to re do the ties. I've had my frame for over 25 years. I made a little hand screen for the 1/4" mesh that is a foot square. When screening soil I use the block to break down the clods. That's why I needed the screen to be heavy duty.

My screen box is made out of pine to keep the weight down. The boards that it sits on are oak.
