About Blue Creeping Speedwell
Veronica umbrosa 'Georgia Blue' · also called Blue Creeping Speedwell, Georgia Blue Speedwell · flowering
Blue Creeping Speedwell is a low, spreading semi-evergreen perennial bearing masses of brilliant cobalt-blue flowers with white centres from late winter into spring. Its dark, bronzed foliage remains attractive through winter. A tough, versatile ground cover suited to rock gardens, borders, and between paving stones in temperate gardens.
Mature size: 10–15 cm tall; spreads 30–45 cm wide
Watch for — Vine weevil: Vine weevil larvae feed on roots, causing sudden collapse of sections of the mat. Apply biological control (Steinernema kraussei nematodes) to soil in late summer or early autumn.
How to tell blue creeping speedwell needs repotting
Repotting on a calendar is less reliable than reading the plant. For blue creeping speedwell, watch for these signs:
- Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
- The pot is so packed that water runs straight through in seconds and barely wets the soil.
- It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
- Growth and (for blue creeping speedwell) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.
For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.
How often to repot blue creeping speedwell
Only every 2–4 years, when genuinely crowded. Blue Creeping Speedwell is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. Prostrate, mat-forming semi-evergreen perennial.
What size pot to step blue creeping speedwell up to
Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Blue Creeping Speedwell positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping blue creeping speedwell into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.
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 blue creeping speedwell
Early spring, just as new growth restarts, is the ideal window for blue creeping speedwell. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.
Step-by-step: repotting blue creeping speedwell
- Confirm it actually needs it. Slide blue creeping speedwell out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
- Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
- Ease it out gently. Water lightly the day before, then tip blue creeping speedwell out, supporting the base. Tease the outer roots free only enough to stop them circling.
- Repot at the same depth. Add a layer of fresh free-draining loam or sandy loam, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
- Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.
Aftercare
Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water blue creeping speedwell again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.
The right soil mix for blue creeping speedwell
Blue Creeping Speedwell wants free-draining loam or sandy loam. Grows in most well-drained fertile soils; pH 6.0–7.5 is ideal. Amend heavy clay with horticultural grit. Excellent drainage is essential to prevent crown and root rot, particularly over winter. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.
Repotting blue creeping speedwell — frequently asked questions
How often should you repot blue creeping speedwell?
Only every 2–4 years, when genuinely crowded for blue creeping speedwell. Only repot blue creeping speedwell every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using free-draining loam or sandy loam. The key mistake is over-potting: a too-big pot stays wet and rots the roots.
What size pot does blue creeping speedwell need?
Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Blue Creeping Speedwell positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping blue creeping speedwell into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot. Use our pot size calculator to size it from the plant's current pot and root spread.
When is the best time of year to repot blue creeping speedwell?
Early spring, just as new growth restarts, is the ideal window for blue creeping speedwell. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.
Does blue creeping speedwell like to be root-bound?
Yes — blue creeping speedwell genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.
Should you fertilise blue creeping speedwell after repotting?
Not immediately. Wait about 4 weeks after repotting blue creeping speedwell. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
