About Camellia 'Water Lily'

Camellia x williamsii 'Water Lily' · also called Water Lily camellia · flowering

Camellia x williamsii 'Water Lily' is an elegant cultivar bearing formal double, soft pink flowers reminiscent of a water lily in bloom. A williamsii hybrid, it is notably free-flowering and has the desirable trait of dropping spent blooms cleanly. Hardy and suited to UK gardens. Mildly toxic to pets if ingested.

Growth habit: Upright, bushy evergreen shrub

What fertiliser camellia 'water lily' actually wants — and why

Camellia 'Water Lily' is an acid-loving plant — it can only take up nutrients in acidic soil, so the feed itself matters less than using an ericaceous formula and never liming.

For the language behind the three numbers on the bottle — what nitrogen, phosphorus and potassium each do — see the NPK ratio explained entry. The short version for camellia 'water lily': match the feed to the job the plant is doing right now, not to a generic “plant food” on the shelf.

How often to feed camellia 'water lily', and which months

Feeding only earns its keep while the plant is in active growth and can use the nutrients — pour feed into a dormant or low-light plant and it simply builds up as root-burning salt. For camellia 'water lily':

Feed with a specialist ericaceous fertiliser in spring after flowering and again in midsummer. Avoid high-phosphorus feeds; a balanced slow-release ericaceous granule applied in March is a convenient approach for garden plants. In practice: an ericaceous feed in spring as growth resumes, repeated through the main growing months; never apply lime, bonemeal or wood ash, which raise pH.

The dormant-season rule matters more than the exact interval: skip feeding entirely when camellia 'water lily' is resting. For the wider context on indoor feeding rhythms across the seasons, the houseplant fertiliser schedule walks through the year month by month.

What strength to mix for camellia 'water lily'

Follow the ericaceous product's own rate — these are formulated for the plant, so the dilution on the label is right for camellia 'water lily'. The variable that actually matters is pH, not concentration.

Feeding always goes onto already-damp soil, never dry roots — water camellia 'water lily' first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the camellia 'water lily' watering schedule.

Signs you are over-feeding camellia 'water lily'

Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for camellia 'water lily':

Brown, scorched leaf margins from too strong or too frequent a dose.
White salt crust on the soil surface.
Soft, lush growth that fruits or flowers poorly.

Signs you are under-feeding camellia 'water lily'

Yellowing leaves with green veins (iron chlorosis from high pH).
Weak growth, poor cropping and an overall pale, stressed look.
Stunted new shoots in spring despite adequate water and light.

Flushing and leaching the salts

Flush camellia 'water lily' with rainwater (not hard tap water, which raises pH) if salts build up; better still, mulch with pine needles or composted bark and water with rainwater to hold the acidity.

Organic vs synthetic feeds for camellia 'water lily'

Organic options

Composted pine bark, pine-needle mulch, used coffee grounds and an organic ericaceous feed gently maintain acidity. UK: Vitax or Westland Ericaceous; US: Espoma Holly-tone or Dr. Earth Acid Lovers. Slow, soil-improving, hard to overdo.

Synthetic / liquid feeds

A liquid or granular ericaceous feed — UK: Miracle-Gro Ericaceous, Vitax or Westland; US: Miracle-Gro Acid-Loving Plant Food or Espoma Holly-tone. Pair with rainwater and an acidic mulch for it to work.

Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

Fertilising camellia 'water lily' — frequently asked questions

What fertiliser does camellia 'water lily' need?

An ericaceous (acidic) fertiliser, formulated to keep the soil pH low and supply iron and trace elements in a form acid-loving roots can absorb. Ordinary feeds and any lime lock out iron and yellow the leaves. Camellia 'Water Lily' is an acid-loving plant — it can only take up nutrients in acidic soil, so the feed itself matters less than using an ericaceous formula and never liming.

How often should I feed camellia 'water lily'?

What does over-feeding camellia 'water lily' look like?

Brown, scorched leaf margins from too strong or too frequent a dose. White salt crust on the soil surface. Soft, lush growth that fruits or flowers poorly. Feeding camellia 'water lily' an ordinary fertiliser, or growing it in hard tap water / limey soil, is the defining mistake — it triggers lime-induced chlorosis (yellow leaves, green veins) no amount of feeding fixes until the pH comes down.
