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.
Preferred mix: Acidic, humus-rich, free-draining ericaceous compost or soil
Watch for — Bud drop: The most common complaint; caused by drought stress during bud set (late summer to autumn), root disturbance, or sudden cold snaps; water consistently and avoid moving plants in autumn.
Why camellia 'bob hope' needs this mix
Camellia 'Bob Hope' is a true acid-lover — it physically cannot take up iron above about pH 5.5, so an ericaceous mix is not optional, it is survival.
- Camellia 'Bob Hope' has evolved on acidic, peaty ground and depends on soil fungi that only function in acid conditions — raise the pH and it starves even in "rich" soil.
- In a too-alkaline mix iron and manganese lock up chemically, so the youngest leaves yellow between green veins (lime-induced chlorosis) and the plant fades out.
- Its fine, shallow roots also want an open, free-draining structure, not a heavy clay or claggy compost.

What goes wrong with the wrong mix
The wrong soil is one of the most common reasons camellia 'bob hope' struggles, and the damage often shows up weeks later as a watering problem. For this species specifically:
- Ordinary multipurpose or garden compost is far too alkaline for camellia 'bob hope' — expect classic yellowing, weak growth and a slow decline over a season or two.
- Hard tap water slowly pushes the pH up too, undoing a good mix; rainwater is strongly preferred for watering.
- Lime, mushroom compost or wood ash anywhere near this plant is actively harmful.
Planting camellia 'bob hope' in standard compost or limey garden soil. Without an acidic (ericaceous) medium it will yellow and fail no matter how well you water and feed it.
pH — does it matter for camellia 'bob hope'?
This is the whole game: Camellia 'Bob Hope' needs pH 4.5-5.5. Test it, use ericaceous compost (and an ericaceous feed), and water with rainwater where you can to keep the pH from creeping up.
If you want to check or adjust it, the soil pH guide walks through testing and the safe ways to nudge a mix more acidic or more alkaline.
DIY mix vs a bagged one
Bagged ericaceous compost is the correct, easy base for camellia 'bob hope'; just open it up with bark and grit per the ratio above. Do not try to acidify ordinary compost by guesswork — it rarely holds.
Drainage and the pot
Containers are often easier than open ground because you control the pH completely. Use a pot with good drainage and an ericaceous mix; never let it sit waterlogged.
Top up or refresh the ericaceous mix yearly and test the pH each spring — it naturally drifts upward over time, especially if watered with tap water. When the time comes, our repotting guide for camellia 'bob hope' covers the timing and technique step by step.
