About Nepeta sibirica 'Souvenir d'André Chaudron'

Nepeta sibirica 'Souvenir d'André Chaudron' · also called Siberian catmint, Blue Beauty catmint · flowering

Nepeta sibirica 'Souvenir d'André Chaudron', also sold as 'Blue Beauty', is an upright catmint bearing large, deep lavender-blue flowers on erect stems through summer above aromatic, toothed foliage. Taller and more vertical than mounding catmints, it spreads by runners to form colonies. Loved by bees, it is hardy, drought-tolerant and good for naturalistic borders.

Growth habit: Upright, running perennial spreading by rhizomes to form spreading colonies; more vertical and wandering than clump-forming catmints.

What fertiliser nepeta sibirica 'souvenir d'andré chaudron' actually wants — and why

Nepeta sibirica 'Souvenir d'André Chaudron' is an easy, light foliage feeder — a half-strength balanced liquid feed through the growing months keeps it green without forcing weak, sappy growth.

A balanced general houseplant feed (roughly even N-P-K) is exactly right — it is grown for foliage, so steady, moderate nitrogen for healthy leaves is the goal, not a bloom or root formula.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for nepeta sibirica 'souvenir d'andré chaudron': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed nepeta sibirica 'souvenir d'andré chaudron', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For nepeta sibirica 'souvenir d'andré chaudron':

Low requirement. A light spring mulch suffices; avoid rich feeding, which weakens the stems and makes the running roots spread more aggressively. Treat that as sparingly through the growing season between spring through early autumn (roughly March to September); ease off in autumn and stop entirely in the low light of winter.

The dormant-season rule matters more than the exact interval: skip feeding entirely when nepeta sibirica 'souvenir d'andré chaudron' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for nepeta sibirica 'souvenir d'andré chaudron'

Half strength is the safe default for nepeta sibirica 'souvenir d'andré chaudron' — houseplant feeds are formulated strong, and the diluted dose is gentler on the roots while still ample for foliage.

Feeding always goes onto already-damp soil, never dry roots — water nepeta sibirica 'souvenir d'andré chaudron' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the nepeta sibirica 'souvenir d'andré chaudron' watering schedule.

Signs you are over-feeding nepeta sibirica 'souvenir d'andré chaudron'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for nepeta sibirica 'souvenir d'andré chaudron':

Brown, crispy leaf tips and edges with no sign of underwatering.
A white, crusty salt deposit on the soil surface or pot rim.
Weak, pale, stretched new growth that flops.
Lower leaves yellow and drop while the soil is correctly watered.

Signs you are under-feeding nepeta sibirica 'souvenir d'andré chaudron'

Uniformly pale or yellow-green leaves, oldest first.
Noticeably small new leaves and stalled growth in good light and season.
A generally tired, lacklustre look despite correct watering and light.

If the symptoms point at watering, light or roots rather than nutrition, the full nepeta sibirica 'souvenir d'andré chaudron' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush the pot of nepeta sibirica 'souvenir d'andré chaudron' with plain water until it runs freely from the base every couple of months in the feeding season — it washes out the fertiliser salts that cause brown tips.

Organic vs synthetic feeds for nepeta sibirica 'souvenir d'andré chaudron'

Organic options

A diluted seaweed or worm-casting feed, or fish emulsion if you can tolerate the smell indoors. UK: Westland or Baby Bio Organic, dilute seaweed; US: Espoma Indoor! or Neptune's Harvest fish & seaweed. Slow, gentle and hard to overdo.

Synthetic / liquid feeds

A general-purpose houseplant liquid at half strength — UK: Baby Bio, Westland Houseplant Feed or Phostrogen; US: Miracle-Gro Indoor Plant Food or Schultz. Convenient and fast-acting; the only risk is overdoing it.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.
