Planting a Bulb

[HiOrcDen]

So I hope it's okay if, just this once, I ask abut a plant which is not an Orchid! lol

I'm planting a Voodoo Lily Bulb. Directions say to plant 5-7" beneath the soil surface. Is this distance measured from the base of the corm, or from the top, because it seems pretty deep to measure from the top?

Should I use my Miracle Gro cactus mix, or even regular Miracle Gro? Or vermiculite. Would I add pumice or perlite?

From the top. Tuberous aroids usually have a amooth, rounded bottom and a rough top, with the undeveloped growth a sharp cone. They only root from the top.

Soil mix isn't very important for this plant. Plant it, water well then wait to water again until it emerges.

Keep in mind it is a spider mite magnet. Spray the whole plant with water once a week to help prevent them.
