About Chocolate Persimmon
Diospyros kaki 'Chocolate' · also called Chocolate persimmon, brown-flesh persimmon · edible
Chocolate is a pollination-variant Asian persimmon: when seeded it develops sweet, brown-flecked, cinnamon-spice flesh and can be eaten firm, but seedless fruit stays astringent until soft. A pollinator nearby maximises the prized brown flesh. It wants full sun, deep well-drained soil and a warm autumn, and is hardy to roughly minus 12 Celsius once established.
Growth habit: Deciduous tree with glossy leaves and good autumn colour; a pollination-variant type whose flesh browns and sweetens when seeded, so a pollinating male-flowered persimmon nearby improves results.
Watch for — Fruit drop: Young or over-fed trees shed developing fruit. Limit nitrogen, water evenly and accept some natural thinning.
What fertiliser chocolate persimmon actually wants — and why
Chocolate Persimmon feeds in two distinct phases — balanced to build the plant, then high-potassium the moment flowering starts to set and fill a heavy crop.
Balanced (even N-P-K) at planting for roots and frame, then switch to a high-potassium ("high-potash") tomato-style feed once the first flowers open — potassium is what sizes and ripens fruit, not nitrogen.
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 chocolate persimmon: 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 chocolate persimmon, 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 chocolate persimmon:
Light feeder. Compost or a balanced fruit-tree fertiliser in early spring is sufficient; avoid heavy nitrogen, which drives fruit drop and soft growth. So: a balanced feed or compost at planting, then a high-potash liquid every 1-2 weeks from first flower through harvest across the main season (spring through early autumn).
The dormant-season rule matters more than the exact interval: skip feeding entirely when chocolate persimmon 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 chocolate persimmon
Follow the crop-feed label rate for chocolate persimmon — these are calibrated for hungry vegetables. Consistency through fruiting matters more than strength; erratic feeding causes problems like blossom-end rot.
Feeding always goes onto already-damp soil, never dry roots — water chocolate persimmon first if the soil is dry, then apply the diluted feed. The companion question is when to water at all, covered in the chocolate persimmon watering schedule.
Signs you are over-feeding chocolate persimmon
Over-feeding is far more common — and more damaging — than under-feeding for most plants. The classic tells for chocolate persimmon:
- Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen).
- Lush foliage hiding the crop; soft growth prone to pests and disease.
- Salt crust on the soil and scorched leaf edges in containers.
Signs you are under-feeding chocolate persimmon
- Pale, yellowing lower leaves and stunted growth.
- Small fruit, poor set, and a quickly exhausted plant.
- Blossom-end rot and weak cropping from erratic or insufficient feeding.
If the symptoms point at watering, light or roots rather than nutrition, the full chocolate persimmon care brief covers soil, humidity and the common problems for this species.
Flushing and leaching the salts
In containers, fertiliser salts build up fast — water chocolate persimmon thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
Organic vs synthetic feeds for chocolate persimmon
Organic options
Garden compost or well-rotted manure dug in before planting, plus a liquid comfrey or seaweed feed once fruiting starts. UK: comfrey feed or organic Tomorite; US: Espoma Tomato-tone or Neptune's Harvest. Builds soil and feeds in one.
Synthetic / liquid feeds
A balanced feed at planting then a high-potash tomato feed in fruiting — UK: Growmore at planting then Tomorite (Levington) or Phostrogen; US: a balanced 10-10-10 then Miracle-Gro Tomato or a bloom booster.
Brand names are examples, not endorsements, and UK and US ranges differ — check the label’s own NPK and dilution rate, since formulations change.

What does over-feeding chocolate persimmon look like?
Vigorous dark-green leafy growth but few flowers or fruit (excess nitrogen). Lush foliage hiding the crop; soft growth prone to pests and disease. Salt crust on the soil and scorched leaf edges in containers. Staying on a high-nitrogen feed once chocolate persimmon starts flowering is the classic error — you get a huge leafy plant and a disappointing crop. Switch to high-potash the moment flowers appear.
Should I flush the soil of chocolate persimmon?
In containers, fertiliser salts build up fast — water chocolate persimmon thoroughly so excess drains from the base each time, and flush pots with plain water every few weeks to prevent a damaging salt build-up.
