About Ficus microcarpa

Ficus microcarpa · also called Chinese Banyan, Indian Laurel Fig · houseplant

Ficus microcarpa is a glossy-leaved evergreen fig prized as an indoor bonsai for its thick, fused aerial roots and dense canopy. It thrives in bright, stable light, dislikes sudden moves, and drops leaves when stressed. A vigorous, forgiving subject once settled, it tolerates pruning hard and back-buds readily, rewarding patient ramification work.

Mature size: As a houseplant or bonsai typically kept 20-100 cm tall; in habitat a large banyan reaching 15-20 m with a spreading buttressed crown.

Watch for — Pale, oversized leaves: A sign of too little light; growth stretches and internodes lengthen. Move to a brighter position to restore compact, dark foliage.

How to tell ficus microcarpa needs repotting

Repotting on a calendar is less reliable than reading the plant. For ficus microcarpa, 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 ficus microcarpa

Every 2–3 years, into bone-dry mix. Ficus microcarpa's growth habit — evergreen broadleaf tree with a thick, smooth pale trunk, dense glossy canopy, and a strong tendency to fuse roots and produce aerial roots in humid conditions; vigorous and quick to back-bud after pruning. — sets the pace.

What size pot to step ficus microcarpa up to

Use a pot only one size up — or even the same pot with fresh gritty mix if the roots have room. Ficus microcarpa 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.

The best time of year to repot ficus microcarpa

Spring or summer, while ficus microcarpa 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 ficus microcarpa

Repot dry. Do not water ficus microcarpa 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 free-draining bonsai or houseplant mix 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 ficus microcarpa 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 ficus microcarpa 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 ficus microcarpa

Ficus microcarpa wants free-draining bonsai or houseplant mix. Use a gritty, open mix such as akadama blended with pumice and bark, or a quality houseplant compost cut with perlite and grit. The roots want air and fast drainage; dense, water-retentive soil invites root rot. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting ficus microcarpa — frequently asked questions

How often should you repot ficus microcarpa?

Every 2–3 years, into bone-dry mix for ficus microcarpa. Repot ficus microcarpa every 2–3 years into a snug pot of free-draining bonsai or houseplant mix, 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 ficus microcarpa need?

When is the best time of year to repot ficus microcarpa?

Should you water ficus microcarpa after repotting?

No — not straight away. Repot ficus microcarpa 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 ficus microcarpa after repotting?

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