About Nevada Lewisia

Lewisia nevadensis · also called Nevada Lewisia, Nevada Bitterroot · flowering

Found in moist mountain meadows, streambanks, and subalpine grasslands throughout the western United States, Lewisia nevadensis is a deciduous, taproot-forming alpine perennial that produces a rosette of narrow, fleshy leaves and starry white to pale pink flowers in late spring. Unlike the evergreen L. cotyledon, it goes completely dormant after flowering and must be kept dry during summer to prevent the taproot rotting. The most critical care point is allowing the plant to experience natural summer drought during dormancy. Lewisia is not listed by the ASPCA; classified as mildly-toxic as a precaution.

Mature size: 5–10 cm tall in flower, 8–15 cm wide

Watch for — Taproot rot during summer dormancy: This is the single most common cause of failure: continued watering or summer rainfall reaches the dormant taproot and causes fatal rot. Ensure the plant is kept bone-dry once foliage dies back, ideally under glass or a raised canopy.

How to tell nevada lewisia needs repotting

Repotting on a calendar is less reliable than reading the plant. For nevada lewisia, 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 nevada lewisia

Every 2–3 years, into bone-dry mix. Nevada Lewisia's growth habit — deciduous, ground-hugging rosette perennial growing from a thick, fleshy taproot; completely dormant from midsummer to early autumn. — sets the pace.

What size pot to step nevada lewisia up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Nevada Lewisia 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 nevada lewisia

Spring or summer, while nevada lewisia 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 nevada lewisia

Repot dry. Do not water nevada lewisia 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 very well-drained sandy or gritty loam, slightly acidic to neutral (ph 6.5–7.5) 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 nevada lewisia 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 nevada lewisia 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 nevada lewisia

Nevada Lewisia wants very well-drained sandy or gritty loam, slightly acidic to neutral (ph 6.5–7.5). Plant in a mix of sharp sand and lean loam (1:1) with added perlite. Avoid any clay or moisture-retentive material. Elevate the crown above the surrounding soil level and surround with fine gravel to ensure perfect drainage at the collar. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting nevada lewisia — frequently asked questions

How often should you repot nevada lewisia?

Every 2–3 years, into bone-dry mix for nevada lewisia. Repot nevada lewisia every 2–3 years into a snug pot of very well-drained sandy or gritty loam, slightly acidic to neutral (ph 6.5–7.5), 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 nevada lewisia need?

When is the best time of year to repot nevada lewisia?

Should you water nevada lewisia after repotting?

No — not straight away. Repot nevada lewisia into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise nevada lewisia after repotting?

Not immediately. Wait about 3 weeks after repotting nevada lewisia. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
