Why ZZ plants need faster drainage
ZZ plants store water in underground rhizomes. Dense saturated soil can keep those tissues wet longer than necessary.
A simple starting blend
Start with cactus mix and add perlite until the texture feels loose and airy. The exact amount depends on how dense the bagged mix is and how quickly your home dries pots.
Pot size matters
A pot only slightly larger than the root system is easier to manage than a very large container full of wet mix.
Low light changes watering
ZZ plants can tolerate low light, but water use slows there. Even fast-draining soil may need much longer between waterings.
FAQ
Can I use regular potting soil?
Yes if amended for drainage, but dense moisture-heavy soil is harder to manage.
