Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its light weight after processing. PropertiesWhen it reaches temperatures of 850–900 °C, perlite softens (since it is a glass). Water trapped in the structure of the material vapourises and escapes, and this causes the expansion of the material to 7–16 times its original volume. The expanded material is a brilliant white, due to the reflectivity of the trapped bubbles. Unexpanded ("raw") perlite has a bulk density around 1100 kg/m³ (1.1 g/cm³), while typical expanded perlite has a bulk density of about 30–150 kg/m³. From Wikipedia under the
GNU Free Documentation License I was reading a book on houseplants, and it said that marginata dracaena plants should not be planted perlite. Q. I thought that Perlite was only qadded to soil to keep it kind of moist. Will my margined dracaena plant die if is has perlite in the soil?

It is added to the soil to loosen up hard sandy soil or heavy peat soil. The reason is to add air to the soil moderately and assist drainage. Keeping this in mind the dracaena must like its feet a wee bit damp. Like it may be salvaged from a swampish area of the world? Does it explain what to use when transplanting a crowded plant into a bigger pot? That should give you a clue, as well as the watering / feeding schedule. I would get a recipe card and on side 1 out what to do for the plant on the other what not to do, endangerment to the health.

I mean there are no stores around me that carry vermiculite.. Well all my store has is miracle grow perlite.. If i cant use that what else can i use besides perlite and vermiculite? Asked by Jesse - Thu Jun 25 19:10:07 2009 - - 2 Answers - 0 Comments A. Perlite is actually preferred by many breeders over vermiculite. Just moisten it until it just barely doesn't drip when squeezed and put a slight dry layer right underneath the eggs. Also do NOT buy miracle grow perlite or other brands that put fertilizers in the perlite. Answered by Quixotic - Thu Jun 25 20:27:06 2009 Whats the difference between compost and soil?
