About Armenian Speedwell

Veronica armena · also called Armenian speedwell, Gentian speedwell · flowering

Veronica armena is a dwarf alpine perennial native to mountainous regions of Turkey, Armenia, and the Caucasus, where it colonises dry, sunny, rocky slopes. It forms a tight evergreen carpet of finely divided, needle-like dark-green foliage under 10 cm tall, studded with small but vivid gentian-blue flowers with a white eye in late spring to early summer. Its most important care requirement is full sun and perfectly drained, lean soil — it dislikes shade and wet winters intensely. Veronica is listed as non-toxic to cats and dogs by the ASPCA.

Mature size: 5–8 cm tall, spreading 20–30 cm wide.

How to tell armenian speedwell needs repotting

Repotting on a calendar is less reliable than reading the plant. For armenian speedwell, 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 armenian speedwell

Every 2–3 years, into bone-dry mix. Armenian Speedwell's growth habit — prostrate, mat-forming evergreen perennial with needle-like foliage forming a dense low carpet. — sets the pace.

What size pot to step armenian speedwell up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Armenian Speedwell 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 armenian speedwell

Spring or summer, while armenian speedwell 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 armenian speedwell

Repot dry. Do not water armenian speedwell 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 sharply drained, gritty, alkaline to neutral soil (ph 6.5–8.0). 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 armenian speedwell 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 armenian speedwell 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 armenian speedwell

Armenian Speedwell wants very sharply drained, gritty, alkaline to neutral soil (ph 6.5–8.0).. Mimics the thin, rocky alkaline soils of its native highlands. Mix standard loam with at least 50% coarse grit or pea gravel to ensure rapid drainage. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

How often should you repot armenian speedwell?

Every 2–3 years, into bone-dry mix for armenian speedwell. Repot armenian speedwell every 2–3 years into a snug pot of very sharply drained, gritty, alkaline to neutral soil (ph 6.5–8.0)., 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.

When is the best time of year to repot armenian speedwell?

Should you water armenian speedwell after repotting?
