It stays small, around 25 to 30 cm. As a Dracaena trifasciata cultivar it is drought-tolerant, low-light tolerant and very forgiving of neglect.

Mature size: Roughly 25-30 cm tall and 20-30 cm wide; a neat, compact cultivar.

How to tell sansevieria trifasciata whitney needs repotting

Repotting on a calendar is less reliable than reading the plant. For sansevieria trifasciata whitney, 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.

What size pot to step sansevieria trifasciata whitney up to

The best time of year to repot sansevieria trifasciata whitney

Spring or summer, while sansevieria trifasciata whitney 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 whitney

Repot dry. Do not water sansevieria trifasciata whitney 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 whitney 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 whitney 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 whitney

Sansevieria Trifasciata Whitney wants free-draining cactus or succulent mix. Gritty cactus/succulent compost, or houseplant mix amended 1:1 with perlite or coarse sand. Reliable drainage and a holed pot keep the compact crown from rotting. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
