About Veronica spicata 'Royal Candles'

Veronica spicata 'Royal Candles' · also called Royal Candles speedwell · flowering

A compact, clump-forming spike speedwell prized for dense, upright violet-blue flower spires from early to midsummer. 'Royal Candles' (sometimes sold as 'Glory') is a tidy, free-flowering selection that draws bees and butterflies, tolerates drought once established, and rebounds with a second flush if deadheaded. Reliably hardy and low-maintenance in full sun and sharp-draining soil.

Mature size: About 40-50 cm tall and 30-45 cm wide.

Watch for — Root and crown rot: From wet winter soil; the most common cause of plant loss, so prioritise sharp drainage on clay.

How to tell veronica spicata 'royal candles' needs repotting

Repotting on a calendar is less reliable than reading the plant. For veronica spicata 'royal candles', 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 veronica spicata 'royal candles') 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 veronica spicata 'royal candles'

Only every 2–4 years, when genuinely crowded. Veronica spicata 'Royal Candles' 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. Compact, upright clump-forming herbaceous perennial that spreads slowly into a neat mound topped with vertical bottlebrush spikes..

What size pot to step veronica spicata 'royal candles' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Veronica spicata 'Royal Candles' 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 veronica spicata 'royal candles' 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 veronica spicata 'royal candles'

Early spring, just as new growth restarts, is the ideal window for veronica spicata 'royal candles'. 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 veronica spicata 'royal candles'

Confirm it actually needs it. Slide veronica spicata 'royal candles' 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 veronica spicata 'royal candles' 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 well-drained loamy garden soil, 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 veronica spicata 'royal candles' 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 veronica spicata 'royal candles'

Veronica spicata 'Royal Candles' wants well-drained loamy garden soil. Adapts to most fertile, free-draining soils with a neutral to slightly alkaline pH. Wet, heavy clay in winter is the main killer; improve drainage with grit or compost on dense soils. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting veronica spicata 'royal candles' — frequently asked questions

How often should you repot veronica spicata 'royal candles'?

Only every 2–4 years, when genuinely crowded for veronica spicata 'royal candles'. Only repot veronica spicata 'royal candles' 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 well-drained loamy garden soil. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does veronica spicata 'royal candles' need?

When is the best time of year to repot veronica spicata 'royal candles'?

Does veronica spicata 'royal candles' like to be root-bound?

Yes — veronica spicata 'royal candles' 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 veronica spicata 'royal candles' after repotting?

Not immediately. Wait about 4 weeks after repotting veronica spicata 'royal candles'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
