The best mixing ratio of the three ingredients is two parts sand, two parts gardening soil, and one-part perlite or pumice. Translating this to cups makes it 3 cups of sand, 3 cups of soil, and 1.5 cups of perlite or pumice. The purpose of pumice or perlite is to aid in aeration and drainage.

Perlite is a mined siliceous rock that is heated and expanded, or “popped” like popcorn, into a white lightweight material, while pumice is a soft, insert-mined stone that often comes from Oregon.

How much pumice should I add to soil?

To improve drainage for plants such as succulents, mix 25% pumice with 25% garden soil, 25% compost and 25% large grain sand. For plants that are prone to rotting, like some euphorbias, amend the soil with 50% pumice or in lieu of amending the soil, fill the planting hole with pumice so the roots are surrounded by it.

What can I use instead of pumice for plants?

No. Pumice is best (I explain why below), but many other options work: perlite, decomposed granite, rice-sized bits of gravel and even chicken grit. Aim for about two parts inorganic coarse-grained sand or fine crushed rock to one part organic (i.e. plant-based) material (like compost).

What is pumice good for?

A pumice stone is formed when lava and water mix together. It's a light-yet-abrasive stone used to remove dry, dead skin. A pumice stone can also soften your calluses and corns to reduce pain from friction. You can use this stone daily, but it's important to know how to properly use it.

Does pumice absorb water?

A: Pumice will not absorb water like a sponge, but it can hold water in its many glassy pores on the surface of the rock. The water will not damage the stone.

Is lava rock same as pumice?

Landscapers know this rock as lava rock. Pumice is a froth of felsic volcanic glass. It is rock foam with so much air in its structure that it often floats on water. ... The basaltic lava starts out black, but oxidation of iron during eruption and emplacement of the scoria turns it red.

Can you propagate in pumice?

The most common rooting medium is pumice, an aerated volcanic rock. Other rooting medium is equal parts of peat moss and sharp sand. The cuttings should be placed in a sunny location, but not exposed to direct sunlight and watered occasionally.

How do you supercharge pumice?

Use the pumice directly from the bag to the potting mix or saturate it with more beneficial microbes and nutrients. This process is known as supercharging or activating. To activate the pumice, soak it in a solution, like compost tea, for one day at least before adding it in the garden soil.

Is pumice good for cactus?

Pumice Grow Media for Cacti and Other Succulents. Cacti and other succulents love well-drained soils—pumice allows enthusiasts to create the ideal soil blend to square optimum drainage rate with watering frequency.
