About Daylily 'Catherine Woodbery'

Hemerocallis 'Catherine Woodbery' · also called Catherine Woodbery daylily, lavender daylily · flowering

Hemerocallis 'Catherine Woodbery' is an award-winning daylily prized for its unusual soft lavender-pink blooms with a green throat, produced in mid-summer. It is lightly fragrant and exceptionally heat-tolerant. Like all daylilies, it is highly toxic to cats and potentially fatal if any part is ingested.

Mature size: 65-75 cm tall in bloom; clumps 50-60 cm wide

How to tell daylily 'catherine woodbery' needs repotting

Repotting on a calendar is less reliable than reading the plant. For daylily 'catherine woodbery', 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 daylily 'catherine woodbery') 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 daylily 'catherine woodbery'

Only every 2–4 years, when genuinely crowded. Daylily 'Catherine Woodbery' 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. Clump-forming semi-evergreen to deciduous perennial with upright arching foliage.

What size pot to step daylily 'catherine woodbery' up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Daylily 'Catherine Woodbery' 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 daylily 'catherine woodbery' 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.

The best time of year to repot daylily 'catherine woodbery'

Early spring, just as new growth restarts, is the ideal window for daylily 'catherine woodbery'. 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 daylily 'catherine woodbery'

Confirm it actually needs it. Slide daylily 'catherine woodbery' 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 daylily 'catherine woodbery' 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 fertile, well-draining loam with good organic matter content, 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 daylily 'catherine woodbery' 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 daylily 'catherine woodbery'

Daylily 'Catherine Woodbery' wants fertile, well-draining loam with good organic matter content. Responds well to enriched soil. Incorporate compost or well-rotted manure at planting. Avoid compacted or waterlogged soils — improved drainage is essential in clay-heavy gardens. pH 6.0–7.0 is optimal. 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 daylily 'catherine woodbery'?

What size pot does daylily 'catherine woodbery' need?

When is the best time of year to repot daylily 'catherine woodbery'?

Does daylily 'catherine woodbery' like to be root-bound?

Yes — daylily 'catherine woodbery' 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 daylily 'catherine woodbery' after repotting?

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