Product Review

This is a very natural mix of lava gravel - the perfect choice for creating a rugged looking setting. Mostly black with just a few rust colored 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. Black 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.
