Pumice vs lava rock. | Bonsai Nut Pumice is much lighter and less porous than lava is and is only available in a white grayish color Lava is heavier by nature and is more porous than what pumice is Lava comes in many sizes and I find what works best for me on large and small trees alike is the 3 8" size
Lava Rock vs Pumice - Bonsai Nut Pumice, Lava, scoria are some of the terms used to describe inorganic substances of volcanic origin They vary by density, color, element composition, vesicle size, water retention capacity If you want to go through the technical information just google the " CANLAVA" website
Pumice and lava rock comparison - Bonsai Nut Pumice and scoria are differentiated by density alone - pumice is less dense than water and scoria is more dense They are both volcanic glass (no or very few minerals) Scoria tends to be more common with more mafic (higher iron and magnesium) volcanoes, but other than that and the density, they are quite similar
Michael Hagedorn on 100% pumice soil - Bonsai Nut The Idaho pumice is much whiter than the pumice I purchased from Bonsai Jack a couple years ago (and whiter than the pumice I purchased locally when I lived in Seattle) The Idaho pumice is also 10% heavier, but that could be due to the aggregate size of the Idaho pumice being smaller and more uniform, and therefore there are smaller air pockets
Do any of you keep your trees in 100% pumice? - Bonsai Nut When I lived on the West Coast, I truly used garbage can loads of pumice However, after years of experimenting, my best results were never with 100% pumice (1) First, piece size was important I was careful to sift all my pumice, toss the fines, and keep the small pieces for smaller bonsai or small trees in development
Pumice size Help! - Bonsai Nut In a 2 gallon pot, should I use 3 8 pumice? I have a bunch of 1 8 to 1 4 size pumice which I can sift to 1 4, but I'm not sure if that's too small for such a large pot I normally use 1 4 fot my bonsais in small pots I'll be mixing 50% pumice and 50% soil
Lava vs pumice vs leca soil test - Bonsai Nut Clearly, pumice holds more water than the other two Lava and leca are close, and have more air filled porosity So if your pots are not holding enough water, add more pumice to the mix If your pots are staying wet too long, add more lava to the mix Leca is a pretty good material, more like lava than pumice in water holding and air holding
hyuga Pumice - Bonsai Nut The color is very muted and the particle size is nicely aligned with Akadama, Kanuma, and Kiryu particles A lot of US pumice can be very white and obnoxious at times The US particle sizes are variable so I wind up with pumice particles too big or too small compared to the akadama particles even when screening
100% pumice why not? - Bonsai Nut Currently I use a mix of akadama, pumice, and kiryu with a little charcoal and sphagnum mixed in That said I've seen first hand the advanced feeder root growth that 100% pumice creates for growers out in oregon Why wouldn't we want to use 100% pumice for all our bonsai soil now that akadama
Pumice - east coast resource? | Bonsai Nut Unfortunately east coast sources of pumice are rare to nonexistent I've purchased bags of pumice and lava from Home Depot A little bit higher price than I've gotten purchasing at shows but it was a guaranteed delivery Soil supply at shows is usually limited and sells out fast Not sure how it compares to Bonsai Jack prices though
