About Lavender Chirita

Chirita lavandulacea · also called Lavender Chirita, Lavender Microchirita · houseplant

Lavender Chirita is a charming annual gesneriad from the Malay Peninsula, growing to 50 cm with soft hairy elliptic leaves and a generous display of pale lavender, white-throated tubular flowers in summer and autumn. Unlike most gesneriads it dies after setting seed, but self-sows freely. It holds an RHS Award of Garden Merit and suits a warm, bright windowsill.

Mature size: Up to 50 cm tall; 20–40 cm spread

Watch for — Leggy growth in low light: Insufficient light causes weak, stretched stems and reduced flowering. Move to a brighter windowsill or supplemental grow lighting to keep the plant compact and floriferous.

How to tell lavender chirita needs repotting

Repotting on a calendar is less reliable than reading the plant. For lavender chirita, 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 lavender chirita

Every 2–3 years, into bone-dry mix. Lavender Chirita's growth habit — erect, branching annual herb; upright-growing to 50 cm with opposite hairy elliptic leaves — sets the pace. Lavender Chirita is a charming annual gesneriad from the Malay Peninsula, growing to 50 cm with soft hairy elliptic leaves and a generous display of pale lavender, white-throated tubular flowers in summer and autumn. Unlike most gesneriads it dies after setting seed, but self-sows freely. It holds an RHS Award of Garden Merit and suits a warm, bright windowsill.

What size pot to step lavender chirita up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Lavender Chirita 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.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot lavender chirita

Spring or summer, while lavender chirita 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 lavender chirita

Repot dry. Do not water lavender chirita 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 well-drained, humus-rich, gritty compost 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 lavender chirita 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 lavender chirita 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 lavender chirita

Lavender Chirita wants well-drained, humus-rich, gritty compost. A mix of peat-free compost with added grit or perlite (roughly 2:1) provides the balance of moisture retention and drainage this annual needs. Avoid heavy soils which cause stem rot. A partially shaded spot in the garden (temperatures permitting) also suits this plant in summer. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting lavender chirita — frequently asked questions

How often should you repot lavender chirita?

Every 2–3 years, into bone-dry mix for lavender chirita. Repot lavender chirita every 2–3 years into a snug pot of well-drained, humus-rich, gritty compost, 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 lavender chirita need?

When is the best time of year to repot lavender chirita?

Should you water lavender chirita after repotting?

No — not straight away. Repot lavender chirita 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 lavender chirita after repotting?

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