SuperFly Bonsai's USA Sifted Black Lava
Black Lava is commonly used in bonsai as an additive to soils. While lava would be a pretty good medium to promote tree growth by itself as it drains very well, it is best to use it in a mix. Black lava will also help prevent soil compaction in your mix and give it structure.

Is It Dirt?
No. Bonsai trees do not like "dirt" and will in most cases die if left in dirt over long periods of time. This is substrate.

What Is In It?
USA Black Lava is a solidified molten rock that was formed after molten lave cooled from a volcano.

 

How Do I Use It?
Repot your bonsai tree in this mixed with other bonsai soil amendments (most common are akadama and pumice) to promote great moisture retention and drainage. Be sure your bonsai pot has holes in the bottom covered by bonsai mesh.
Each micro climate may require different amounts of water. On very hot/dry days you may need to water two/three times while around freezing you may need to water just once per month. Push your finger 1" into the soil and feel for moisture. If it is dry, it is time to water.
2.5 Qt = @ 12 Cups
13L = @ 3.5 Gallons

Washed vs Unwashed
We offer both washed and unwashed lava. 

The washed lava is a premium product that has been sieved twice and washed.  This lava is very clean, dark uniform black and has virtually no dust.  We use the washed lava in all of our premium soil mixes.  The washed lava is more due to all the processes to make it perfect and 100% ready to go.

The unwashed lava has been sieved once and dust will be in the bag, the majority of the product will be the size listed.  I highly suggest sieving the lava inside a tub of water.  This will clean the remaining dust and will cause minimal dust to enter the air.

We also have Red Lava


Please Note: Do not breath the dust from lava as it is very abrasive and not good to get in your lungs or eyes. We sifted the majority of the dust out of the lava prior to bagging, however more will be created in the shipping process. It is recommended to utilize a dust mask whenever dealing with lava dust.  If you purchased unwashed lava, I suggest sieving it in a tub of water or just water in well and most of the dust will just fall out of the drain holes.

Plants & Tree Shipping:
We ship bonsai trees and plants from either our parnter nursery or our in house nursery depending on the tree.  We may limit when we ship trees to help limit their exposure to extreme environments.  For example we may not ship if it will cause the tree to sit in a truck over a weekend or holiday in very low temperatures or very high temps.

If we are shipping from our Harrisburg, PA location, the tree may arrive via any carrier, but usually UPS or USPS.  Time in transit will be 1-2 days in the northeast, 2-3 days in the southeast, 3-4 days in the midwest and usually 5 days for the west coast.

Trees are shipped in custom boxes made just for shipping trees.  Sometimes we wrap the pot and soil in plastic to prevent it from spilling out in transit.  Many times we use packing peanuts as they have proven to be very reliable in keeping trees safe in shipping.  If a box is noticiably damaged, please take pictures prior to opening.

Please Note:  We do not ship plants and trees to California
