About Plum 'Victoria'

Prunus domestica 'Victoria' · also called Victoria plum · edible

Victoria is Britain's most popular plum, an easy, reliably self-fertile dessert-and-cooking variety bearing heavy crops of oval red-flushed yellow fruit with sweet, juicy flesh in late summer. A compact deciduous tree, it crops without a pollination partner but tends to over-set, so thinning improves fruit size and prevents branch-breaking and biennial bearing.

Mature size: On St Julien A around 3-4 m tall and wide; on dwarfing Pixy roughly 2-2.5 m. Suitable for fan-training against a wall.

How to tell plum 'victoria' needs repotting

Repotting on a calendar is less reliable than reading the plant. For plum 'victoria', 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 plum 'victoria' 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 plum 'victoria'

Pot on seedlings as they grow; not a perennial repot. Plum 'Victoria'is grown for one season, so the question is really “how often to pot on” — keep moving it up before the roots circle. Naturally compact, rounded deciduous tree; size set by rootstock (Pixy for dwarf, St Julien A for semi-vigorous). White blossom in early-mid spring, fruit ripening late summer. Branches are brittle when over-laden..

What size pot to step plum 'victoria' up to

Pot plum 'victoria' 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 plum 'victoria'

Pot plum 'victoria' 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 plum 'victoria'

Pot on before it is root-bound. Check plum 'victoria' 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, moisture-retentive but 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 plum 'victoria' 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 plum 'victoria'

Plum 'Victoria' wants deep, fertile, moisture-retentive but well-drained loam. Thrives on slightly acidic to neutral soil (pH 6.0-6.5) and tolerates clay better than most fruit if not waterlogged. Avoid dry, shallow or frost-pocket sites, which reduce cropping and stress the tree. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting plum 'victoria' — frequently asked questions

How often should you repot plum 'victoria'?

Pot on seedlings as they grow; not a perennial repot for plum 'victoria'. Plum 'Victoria' 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, moisture-retentive but 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 plum 'victoria' need?

When is the best time of year to repot plum 'victoria'?

Can you put plum 'victoria' straight into a much bigger pot?

No. Even a fast-growing plum 'victoria' 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 plum 'victoria' after repotting?

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