Watering her is really simple. Keep her tray topped up with water and she’ll absorb what she needs through the lava.
She’ll be ok in semi-shade but is happiest in bright, indirect light. She likes a spot away from harsh sunlight.
She enjoys a moist atmosphere so use a plant misterto spritz her once a week or so. Or put her in the bathroom.
She prefers filtered water, please (you can use tap water that’s been boiled, then cooled). Hard tap water can cause marks on the lava.

In the wild, this schefflera is most commonly found in Taiwanese forests, where it might grow as tall as nine metres. You’d need a considerably bigger rock for that. Growing a schefflera on lava looks very elegant and makes it very easy to look after.
The schefflera’s roots have grown around the lava, a porous stone. As the lava absorbs water from the tray, the plant sucks water from the lava. That means you can’t over-water your plant. It will only take as much as it needs. Just keep the tray about three-quarters full.
If you need to move your schefflera, always be sure to lift it by the tray, not the lava rock, to avoid damaging the rock or the plant. Every piece of lava rock is unique, so the one you receive will differ from the one in the pictures.

It’s not just lava rocks the plant will grow on. In the wild it can affix itself to the trunks of other trees.
