About Malus 'Profusion'

Malus 'Profusion' · also called Profusion Crabapple · flowering

Malus 'Profusion' is a free-flowering ornamental crabapple smothered in deep wine-red blossom in mid-spring. Coppery-purple young leaves mature to bronze-green, and abundant small oxblood-red fruits ripen in autumn, persisting to feed birds. A reliable, hardy small tree, it suits lawns, borders and small gardens needing spring colour.

Mature size: About 7-9 m tall and 7-8 m wide at maturity.

Watch for — Apple scab: Causes black leaf spots and premature defoliation; this cultivar has moderate susceptibility, so clear fallen leaves and keep the canopy open.

How to tell malus 'profusion' needs repotting

Repotting on a calendar is less reliable than reading the plant. For malus 'profusion', watch for these signs:

Thick roots out of the drainage holes, or circling the surface and lifting the plant.
The pot dries out unusually fast and malus 'profusion' wilts between waterings it used to shrug off.
The plant is visibly top-heavy and tips over easily.
Stalled growth and small new leaves over a full season — though with a big specimen, top-dressing is often the better first response before a full repot.

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 malus 'profusion'

Every 2–3 years; top-dress in the in-between years. Malus 'Profusion''s growth habit — small deciduous tree with a rounded, spreading, fairly dense crown and a moderate growth rate; noted for its profuse flowering and heavy fruiting. — sets the pace. Malus 'Profusion' is a free-flowering ornamental crabapple smothered in deep wine-red blossom in mid-spring. Coppery-purple young leaves mature to bronze-green, and abundant small oxblood-red fruits ripen in autumn, persisting to feed birds. A reliable, hardy small tree, it suits lawns, borders and small gardens needing spring colour.

What size pot to step malus 'profusion' up to

Move up exactly one pot size. A heavy malus 'profusion' dropped into a vastly bigger pot sits in a reservoir of wet soil its roots cannot reach, which rots them and destabilises the plant. In the years between repots, lift off and replace the top 3–5 cm of soil (top-dressing) instead — it refreshes nutrients without the shock of a full repot.

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 malus 'profusion'

Early spring, just as new growth restarts, is the ideal window for malus 'profusion'. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting malus 'profusion'

Consider top-dressing first. If malus 'profusion' is not badly root-bound, scrape off and replace the top 3–5 cm of soil instead — far less shock for a big plant that hates moving.
Get help and one size up. For a full repot, choose a pot just one size larger. A heavy plant needs two people and a stable, free-draining pot.
Ease it out on its side. Lay the plant down, slide the pot off, and gently loosen the outer roots. Do not bare-root a mature specimen.
Repot at the same depth. Add fresh fertile, moist but well-drained soil beneath and around the rootball, keeping the original soil line. Firm it so the trunk is stable and upright.
Water and leave it put. Water thoroughly, then leave malus 'profusion' in the same spot and light — moving and repotting at once is what makes it drop leaves.

Aftercare

Leave malus 'profusion' in exactly the same spot and light it was in before — moving and repotting at the same time is what makes a big specimen drop leaves. Water it in well, then let the top of the soil dry before watering again so the larger volume of fresh soil does not stay sodden. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for malus 'profusion'

Malus 'Profusion' wants fertile, moist but well-drained soil. Grows on chalk, clay, loam and sand across a wide pH range; happy in most ordinary garden soils with good drainage. Avoid permanently wet sites. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting malus 'profusion' — frequently asked questions

How often should you repot malus 'profusion'?

Every 2–3 years; top-dress in the in-between years for malus 'profusion'. Fully repot malus 'profusion' only every 2–3 years; in the in-between years just top-dress the top 3–5 cm of soil. Step up one pot size in spring with fertile, moist but well-drained soil. It is heavy and hates being moved, and a vastly oversized pot holds water against the roots and rots them.

What size pot does malus 'profusion' need?

When is the best time of year to repot malus 'profusion'?

Should you top-dress or fully repot malus 'profusion'?

For a big, heavy malus 'profusion', top-dressing — replacing the top 3–5 cm of soil — is the gentler option most years, with a full repot only every 2–3 years. A mature specimen sulks and drops leaves when fully repotted, so do it as rarely as the roots allow.

Should you fertilise malus 'profusion' after repotting?

Not immediately. Wait about 4 weeks after repotting malus 'profusion'. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
