Description
This is a very natural mix of lava gravel - the perfect choice for creating a rugged looking setting. Mostly rust and reds with just a few black pieces blended in. Lava gravel stays put even under a strong flow of water. There is a slight color difference when wet and dry, making it a little easier to know when to water. Red lava gravel gives your Bonsai tree a great look, while preserving water- and air-flow to the roots! This is a great look for rugged Bonsai trees, and can create a stunning contrast between the vibrant green of the tree itself. Gravel, by itself, has little ability to hold nutrients, so this black lava gravel should be used on top of your tree's topsoil. However, just like rocks in real life, the gravel protects the topsoil from erosion and weather. The porous nature of gravel means that, unlike other stones, air and water can still easily make it down to the roots. Gravel is also great for humidity trays, since it changes color slightly when wet. Just a glance at your black lava gravel will tell you whether it's time for watering or to refill the humidity tray. Gravel Gives Bonsai a Distinctive Look - Tinyroots black lava gravel top dressing creates attractive and colorful Bonsai displays that convey power when you're showing off your tree! This package contains three cups, which is enough to cover about one square foot of ground. Three cups is roughly one lb. of gravel.4. Hoffman 14452 Volcanic Lava Rock, 2 Quarts

Description
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 and retains a large amount of moisture, it is best to use it in a mix. Black lava will also help prevent soil compaction in your mix and give it some 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 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
1.25Qt = @ 6 Cups
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 in a well ventilated area whenever dealing with lava dust.
