About Veronica spicata subsp. incana

Veronica spicata subsp. incana · also called silver speedwell, woolly speedwell · flowering

Silver speedwell is a low, drought-tolerant perennial grown as much for its felted silvery-grey foliage as for its dense vertical spikes of violet-blue flowers in early to midsummer. Reaching about 30-45 cm, it thrives in hot, sunny, well-drained spots, draws bees and butterflies, and pairs beautifully with its own bright blooms against the woolly leaves.

Mature size: About 30-45 cm tall in flower and 30-45 cm wide.

Watch for — Crown and root rot: Wet, heavy or rich soil rots the woolly crown. Plant in sharply drained ground, avoid overwatering, and never let it sit in winter wet.

How to tell veronica spicata subsp. incana needs repotting

Repotting on a calendar is less reliable than reading the plant. For veronica spicata subsp. incana, 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 veronica spicata subsp. incana

Every 2–3 years, into bone-dry mix. Veronica spicata subsp. incana's growth habit — low, mat- to clump-forming herbaceous perennial with silvery, woolly lance-shaped leaves and erect terminal flower spikes held well above the foliage. — sets the pace. Silver speedwell is a low, drought-tolerant perennial grown as much for its felted silvery-grey foliage as for its dense vertical spikes of violet-blue flowers in early to midsummer. Reaching about 30-45 cm, it thrives in hot, sunny, well-drained spots, draws bees and butterflies, and pairs beautifully with its own bright blooms against the woolly leaves.

What size pot to step veronica spicata subsp. incana up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Veronica spicata subsp. incana 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 veronica spicata subsp. incana

Spring or summer, while veronica spicata subsp. incana 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 veronica spicata subsp. incana

Repot dry. Do not water veronica spicata subsp. incana 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 sharply drained, lean to average soil 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 veronica spicata subsp. incana 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 veronica spicata subsp. incana 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 veronica spicata subsp. incana

Veronica spicata subsp. incana wants sharply drained, lean to average soil. Tolerates poor, gritty, even sandy ground; pH-adaptable but happiest near neutral. Excellent drainage is non-negotiable, as rich, heavy or wet soil rots the woolly crown and dulls the silver foliage. 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 subsp. incana — frequently asked questions

How often should you repot veronica spicata subsp. incana?

Every 2–3 years, into bone-dry mix for veronica spicata subsp. incana. Repot veronica spicata subsp. incana every 2–3 years into a snug pot of sharply drained, lean to average soil, 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 veronica spicata subsp. incana need?

When is the best time of year to repot veronica spicata subsp. incana?

Should you water veronica spicata subsp. incana after repotting?

No — not straight away. Repot veronica spicata subsp. incana 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 veronica spicata subsp. incana after repotting?

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