About Keitt Mango

Mangifera indica 'Keitt' · also called Keitt mango · tropical

'Keitt' is a very late-season mango bearing large, sweet, nearly fibreless green-skinned fruit that often stays greenish when ripe. A tropical evergreen, it needs heat, full sun and a dry spell to flower, and tolerates marginal warm climates better than many. Frost-sensitive, it crops outdoors only in frost-free zones, or under glass elsewhere.

Mature size: 6-10 m or more in the ground; easily kept to 1.5-3 m as a pruned container or dooryard tree.

Watch for — Anthracnose: Wet, humid weather at flowering lets anthracnose blight blooms and spot fruit and leaves. Improve airflow, keep blooms dry and apply protective fungicide where pressure is high.

How to tell keitt mango needs repotting

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

Roots growing out of the drainage holes, or the rootball lifting the plant proud of the rim.
Soil that has shrunk away from the pot sides and no longer holds water.
The pot is unstable because the plant has grown top-heavy.
Old, compacted, broken-down mix that stays wet too long — for a succulent that is a rot risk, so refresh it even if the pot size is fine.

How often to repot keitt mango

Every 2–3 years, into bone-dry mix. Keitt Mango's growth habit — medium to large evergreen tree with a moderately vigorous, spreading, rounded canopy. flowers in terminal panicles after a cool, dry rest and ripens its very large fruit late in the season. a consistent, productive bearer. — sets the pace.

What size pot to step keitt mango up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Keitt Mango stores water and rots in a large pot of slow-drying soil. A tight terracotta pot that dries fast is far safer than a generous plastic one. Never up-pot a succulent by several sizes.

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 keitt mango

Spring or summer, while keitt mango is in active growth and warm, is best — roots recover fastest then, and the plant is not sitting in cool damp soil. Avoid repotting a succulent in winter dormancy.

Step-by-step: repotting keitt mango

Repot dry. Do not water keitt mango for several days first. Working with dry roots and dry mix dramatically lowers the rot risk for a succulent.
Pick a snug, fast-draining pot. Choose terracotta one size up at most, with a drainage hole. Have gritty deep, free-draining loam ready.
Tip it out and clean the roots. Slide the plant out, crumble off the old soil, and trim any black, mushy or dead roots with clean snips.
Pot into dry mix. Set keitt mango at its original depth in dry gritty mix, firming gently. Do not bury the stem deeper than it was.
Wait a week before watering. Leave it completely dry and out of harsh sun for about 7 days so any damaged roots callus. Only then water lightly.

Aftercare

Keep keitt mango completely dry and out of fierce sun for about a week so any nicked roots callus before they meet moisture; watering a freshly repotted succulent is the classic way to rot it. Then resume the normal lean, dry rhythm. Do not fertilise for about 3 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for keitt mango

Keitt Mango wants deep, free-draining loam. Prefers fertile, well-drained loam at pH 5.5-7.5; tolerates sandy and limestone soils but not standing water. In containers use a gritty, loam-based mix for sharp drainage. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting keitt mango — frequently asked questions

How often should you repot keitt mango?

Every 2–3 years, into bone-dry mix for keitt mango. Repot keitt mango every 2–3 years into a snug pot of deep, free-draining loam, ideally in spring or summer. Let it sit in dry soil and do not water for about a week afterwards so any nicked roots can callus. Over-potting and watering straight away is what rots succulents.

What size pot does keitt mango need?

When is the best time of year to repot keitt mango?

Should you water keitt mango after repotting?

No — not straight away. Repot keitt mango into dry mix and wait about a week before the first watering so any damaged roots callus over. Watering a freshly repotted succulent is the single most common way to rot one.

Should you fertilise keitt mango after repotting?

Not immediately. Wait about 3 weeks after repotting keitt mango. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
