Moonshine Snake Plant Care: Preventing the Silver From Fading

Overview

The Moonshine Snake Plant (Sansevieria trifasciata 'Moonshine', recently reclassified as Dracaena) is a stunning, modern cultivar of the classic houseplant. While traditional Snake Plants feature tall, sword-like leaves banded with dark green and bright yellow, the Moonshine is distinctly minimalist. It produces broad, slightly shorter leaves colored in a striking, ghostly, pale silvery-green.

It possesses the exact same ironclad, indestructible nature as any other Snake Plant, happily surviving months of neglect and bone-dry air. However, there is a catch. If you buy a Moonshine and place it in the same dark, windowless corner where your standard Snake Plant thrives, you will quickly ruin it. The pale coloring is highly unstable, and understanding how to manipulate light is the only way to keep this plant looking beautiful.

Light Requirements: The Secret to the Silver

Standard Snake Plants are famous for their extreme shade tolerance. The Moonshine, however, has a fraction of the chlorophyll (the green pigment used for photosynthesis).

If you place a Moonshine in a low-light environment, the plant realizes it is starving. To save its own life, it will flood its leaves with dark green chlorophyll. Within a few months, your expensive, rare, silvery-white plant will look exactly like a common, dark green Snake Plant. To maintain the silver color, the Moonshine MUST be placed in bright, indirect light. An east or west-facing window is perfect. If given enough bright light, the new leaves will emerge almost completely white before hardening into that signature pale mint-green.

Watering: The #1 Killer

There is really only one way to kill a Moonshine Snake Plant: overwatering. The thick leaves act as giant water reservoirs, allowing the plant to survive severe droughts.

You must allow the potting soil to dry out 100% completely—all the way to the bottom of the pot—before watering. If you are unsure if it is dry, wait another week. In the winter, you may only need to water this plant once every six to eight weeks. When it is finally time, soak the pot thoroughly until water flows out the drainage holes, ensuring the root ball is hydrated, and then ignore it completely for another month.

Temperature and Humidity

This plant prefers warm indoor temperatures ranging from 65°F to 85°F (18°C - 29°C). Keep it away from freezing drafts, as temperatures below 50°F (10°C) can cause cellular damage to the water-filled leaves, turning them to mush. It has zero need for humidity and perfectly tolerates the dry air of centrally heated homes.

Soil and Potting

Because they are so susceptible to root rot, proper drainage is critical. Standard potting soil is far too dense and holds moisture for too long. You must use a fast-draining cactus and succulent mix, heavily amended with coarse sand, perlite, or pumice. Furthermore, Sansevierias have strong, thick rhizomes (underground stems) that spread horizontally. They prefer to be somewhat root-bound and only need to be repotted every 3 to 4 years.

Fertilizing

This plant is an incredibly slow grower and requires almost no supplemental nutrition. Feed it only once a year, right at the start of spring, using a specialized cactus/succulent fertilizer diluted to half strength. Over-fertilizing can chemically burn the roots.

Toxicity

Like all Sansevierias, the Moonshine contains saponins. If ingested by cats or dogs, it is mildly to moderately toxic, causing nausea, drooling, vomiting, and diarrhea. The rigid texture doesn't usually attract chewing pets, but caution is still advised.
