Some plants are sensitive to excessive moisture around their root zone, so it’s sometimes necessary to increase drainage when growing plants in pots. Additionally, standing water at the bottom of the pot can cause root rot. Continue reading “How to Improve Drainage in Plant Pots, The Proper Way to Do It!” to learn about the old gardening myth of adding a layer of rocks to the bottom of a pot to increase drainage.
A highly porous rock called scorium is created when lava cools quickly. Scoria is a more environmentally friendly aeration amendment that wasn’t converted from obsidian rock through an energy-intensive process, and it offers a high surface area for aeration, a great storage site for nutrients within your soil, and improves drainage. Scoria has some water retention qualities as well as excellent drainage. Unlike perlite, scorium lasts a long time and doesn’t quickly decompose into dust. This makes it perfect for No-Til environments, especially when combined with rice hulls to create your soil mix’s aeration component.
Scoria is gathered around the vents of a volcano. Ash cones are the name for the cone-shaped hill Scoria created. There are sizable areas with numerous volcanoes in some parts of the world. Volcanoes that produce scrorea typically have brief eruptions that do not last very long. It is frequently utilized as a lightweight aggregate for concrete or landscaping.

When the Scoria erupts, an explosive inside the volcano, extra gases, and volcanic ash are released. These gases are dissolved in the magma under extreme pressure. When the temperature drops from the surface, the magma from the volcanic eruption solidifies when it enters the air in which the pressure is released. The gases in the melt are not released from the melt without solidification, only when the magma solidifies. These gases produce round or long pores. Gases would not be compressed without these pores, which were vesicles of rapidly emerging gas regions of melt solidification.
Vesicular, dark-colored igneous rock known as scorium may or may not contain crystals. Dark hues like dark brown, black, or purplish red are typical. Most scoria is basaltic or andesitic in composition. Known as scoria, the top of a lava flow is composed of a highly vesicular, rocky substance. It has the appearance of vesicular lava. when the magma’s gases expand to form bubbles as the liquid reaches the surface, forming the rock The bubbles are then retained as the lava solidifies. Areas of recent volcanism, like the Canary Islands and the Italian volcanoes, are prone to scrorea. Due to its vesicles, it has a relatively low density, but it is not as light as pumice. It also has larger vesicles with thicker walls than pumice, which is another difference. It has commercial use as a high-temperature insulating material. It also has applications in landscaping and drainage.
Scoria is a mafic volcanic glass. The basaltic lava is extremely vesicular and has very small ( Pumice is a felsic volcanic glass. It is a type of rock foam with so much air in it that it frequently floats on water. Close examination of fresh pumice shows its glassy nature. Pumice that has weathered over time loses its glassy appearance (volcanic glass quickly disintegrates when exposed to water), but it is still light and rough to the touch.

To give you a little background, a wicking bed is a self-watering raised garden bed that functions by using coarse scoria as the recommended material.
