About Lady of the Night

Brassavola nodosa · also called Lady of the Night Orchid · flowering

Brassavola nodosa is a tough Central American epiphyte famous for its powerful citrus-floral fragrance released after dark. It bears slender, pencil-like leaves and spidery greenish-white flowers with a broad white lip. Forgiving of bright light and drought, it is one of the easiest fragrant orchids for a sunny windowsill.

Mature size: Leaves 15-30 cm long; flowers 7-9 cm across. Forms a rambling clump 25-40 cm wide, often spilling over the pot or mount.

Watch for — Root and base rot: Result of overwatering or a media that stays wet. Let it dry fully between waterings; mounting eliminates the problem entirely.

How to tell lady of the night needs repotting

Repotting on a calendar is less reliable than reading the plant. For lady of the night, 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 lady of the night up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Lady of the Night 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 lady of the night

Spring or summer, while lady of the night 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 lady of the night

Repot dry. Do not water lady of the night 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 free-draining bark, or mounted 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 lady of the night 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 lady of the night 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 lady of the night

Lady of the Night wants very free-draining bark, or mounted. Grows well in a small pot of coarse bark and charcoal, or mounted on cork or a wood slab to mimic its epiphytic habit. Sharp drainage and fast drying at the roots are essential. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
