About Sansevieria Trifasciata Craigii

Dracaena trifasciata 'Craigii' · also called Craig's Snake Plant, White-variegated Snake Plant · houseplant

Sansevieria trifasciata 'Craigii', now Dracaena trifasciata 'Craigii', is a striking white-variegated snake plant with broad sword-shaped leaves edged and streaked in creamy white over green. As tough and drought-proof as the classic snake plant, the heavier variegation means it appreciates a little more light to stay crisp.

Mature size: Typically 60-90 cm (2-3 ft) tall indoors, occasionally to 1.2 m; clumps widen slowly to 30-45 cm.

Watch for — Root and rhizome rot: From overwatering or poor drainage. Bases turn soft and yellow. Repot into gritty mix, trim rotten tissue, and extend the interval between waterings.

How to tell sansevieria trifasciata craigii needs repotting

Repotting on a calendar is less reliable than reading the plant. For sansevieria trifasciata craigii, watch for these signs:

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot sansevieria trifasciata craigii

Every 2–3 years, into bone-dry mix. Sansevieria Trifasciata Craigii's growth habit — slow-growing, clump-forming evergreen that spreads by rhizome, producing upright, broad, sword-shaped leaves in a loose rosette. — sets the pace. Sansevieria trifasciata 'Craigii', now Dracaena trifasciata 'Craigii', is a striking white-variegated snake plant with broad sword-shaped leaves edged and streaked in creamy white over green. As tough and drought-proof as the classic snake plant, the heavier variegation means it appreciates a little more light to stay crisp.

What size pot to step sansevieria trifasciata craigii up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Sansevieria Trifasciata Craigii stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

The best time of year to repot sansevieria trifasciata craigii

Spring or summer, while sansevieria trifasciata craigii is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting sansevieria trifasciata craigii

Repot dry. Do not water sansevieria trifasciata craigii for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty free-draining cactus or succulent mix ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set sansevieria trifasciata craigii at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep sansevieria trifasciata craigii completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for sansevieria trifasciata craigii

Sansevieria Trifasciata Craigii wants free-draining cactus or succulent mix. A gritty cactus/succulent mix, or standard houseplant compost lightened with one-third perlite or pumice, in a pot with drainage holes. Avoid dense, moisture-holding mixes that keep the rhizome wet. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting sansevieria trifasciata craigii — frequently asked questions

How often should you repot sansevieria trifasciata craigii?

Every 2–3 years, into bone-dry mix for sansevieria trifasciata craigii. Repot sansevieria trifasciata craigii every 2–3 years into a snug pot of free-draining cactus or succulent mix, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does sansevieria trifasciata craigii need?

When is the best time of year to repot sansevieria trifasciata craigii?

Should you water sansevieria trifasciata craigii after repotting?
