About Camellia 'Bob Hope'

Camellia japonica 'Bob Hope' · also called Bob Hope Camellia, Japanese Camellia 'Bob Hope' · flowering

Camellia japonica 'Bob Hope' produces large, striking semi-double to peony-form deep red blooms from late winter to mid-spring on a slow-growing, dense evergreen shrub. It is prized for its bold, velvety flowers and glossy dark foliage. Like all camellias, ingestion of any plant part may cause mild gastrointestinal upset in pets.

Growth habit: Slow-growing, dense upright evergreen shrub

Watch for — Vine weevil: Notched leaf margins and wilting indicate adult or larval feeding; apply pathogenic nematodes (Steinernema) to the root zone in late summer.

What fertiliser camellia 'bob hope' actually wants — and why

Camellia 'Bob Hope' 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 'bob hope': 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 'bob hope', 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 'bob hope':

Apply a granular ericaceous fertiliser in early spring as new growth breaks, and a liquid ericaceous feed monthly through summer. Cease feeding by late summer to allow growth to harden before the first frosts. 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 'bob hope' 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 'bob hope'

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

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

Signs you are over-feeding camellia 'bob hope'

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

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 'bob hope'

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.

If the symptoms point at watering, light or roots rather than nutrition, the full camellia 'bob hope' care brief covers soil, humidity and the common problems for this species.

Flushing and leaching the salts

Flush camellia 'bob hope' 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 'bob hope'

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 'bob hope' — frequently asked questions

What fertiliser does camellia 'bob hope' 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 'Bob Hope' 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 'bob hope'?

Apply a granular ericaceous fertiliser in early spring as new growth breaks, and a liquid ericaceous feed monthly through summer. Cease feeding by late summer to allow growth to harden before the first frosts.

What strength of feed for camellia 'bob hope'?

What does over-feeding camellia 'bob hope' 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 'bob hope' 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.
