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.

Mature size: Roughly 4 to 9 m as a standard, commonly held to 2.5 to 4 m by pruning; container-suitable when restricted.

How to tell chocolate persimmon needs repotting

Repotting on a calendar is less reliable than reading the plant. For chocolate persimmon, watch for these signs:

Roots circling the bottom of the module or pot, or poking out of the drainage holes.
The seedling dries out within a day and growth has visibly stalled.
Roots are white and matted in a tight spiral when you tip the plant out.
It has outgrown its current container for the stage of the season — pot chocolate persimmon on before it becomes hard root-bound.

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 chocolate persimmon

Pot on seedlings as they grow; not a perennial repot. Chocolate Persimmonis grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. 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..

What size pot to step chocolate persimmon up to

Pot chocolate persimmon on gradually — a seedling jumped straight into a huge pot sits in cold, wet, airless soil and stalls. Step up one or two sizes at a time as the roots fill each container, finishing in a large final pot or the ground. The aim is roots that never circle and never check.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot chocolate persimmon

Pot chocolate persimmon on through the active growing season, whenever roots fill the current container — there is no single date, just "before it becomes root-bound". Avoid potting on during a cold snap.

Step-by-step: repotting chocolate persimmon

Pot on before it is root-bound. Check chocolate persimmon regularly; move it up as soon as roots reach the edge of the cell or pot, not after they have circled.
Step up one or two sizes. Choose the next container up — not a giant one. Cold, wet, unused soil around a small root system stalls seedlings.
Knock it out gently. Support the stem, tip the pot, and ease the rootball out without breaking it. A little teasing of circled roots at the base is fine.
Pot into rich mix. Set it into fresh deep, fertile, well-drained loam at the same depth (tomatoes are the exception — they can go deeper to root along the stem).
Water in and grow on. Water well, keep it in good light, and resume feeding once it is established and growing again.

Aftercare

Water chocolate persimmon in well and keep it in bright light; a freshly potted-on seedling can wilt for a day while roots settle, so do not overcompensate by drowning it. Do not fertilise for about 1 week — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for chocolate persimmon

Chocolate Persimmon wants deep, fertile, well-drained loam. Adaptable across pH 6.0 to 7.5 and tolerant of clay where drainage is good. Avoid waterlogged sites, which the deep taproot dislikes. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting chocolate persimmon — frequently asked questions

How often should you repot chocolate persimmon?

Pot on seedlings as they grow; not a perennial repot for chocolate persimmon. Chocolate Persimmon is a seasonal crop, so you pot it on as a growing plant rather than repotting a perennial. Step seedlings up gradually into deep, fertile, well-drained loam so the roots never circle the cell, ending in a large final container. A root-bound transplant stalls and never fully recovers.

What size pot does chocolate persimmon need?

When is the best time of year to repot chocolate persimmon?

Can you put chocolate persimmon straight into a much bigger pot?

No. Even a fast-growing chocolate persimmon should only go up one pot size at a time. A vastly oversized pot holds a reservoir of wet soil the roots cannot reach, which stays cold and soggy and rots the roots — the opposite of what you wanted.

Should you fertilise chocolate persimmon after repotting?

Not immediately. Wait about 1 week after repotting chocolate persimmon. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
