Hello! I picked up a nice looking lava rock yesterday, and I was wondering, how you are supposed to clean a lava rock? I have soaked it for over 3 days, in hot water (no soap), and I have scrubbed it thoroughly. I also here that Lava Rock is good for Java Fern (is this true?), if you just tie it onto the rock, with fishing line.
P.S. I am a beginner everything “plant” related, does Java Fern need liquid Fertilizer?
Here is a picture of said lava rock. Thank you!
