Every March, something happens in offices across Hong Kong that nobody discusses: the plants that have been sitting quietly in too-small pots for two years begin to show the strain. Roots have run out of room. Soil has compacted. Water runs straight through without being absorbed. The plant is politely but insistently asking for a new home. Spring is the right moment to answer.

Does Your Plant Need Repotting?

A plant doesn’t require repotting every year — and unnecessary repotting stresses it. Look for these signals first:

Roots growing out of the drainage holes
Water draining too fast — running straight through without being absorbed
Plant visibly too large for its pot; top-heavy, unstable
Soil drying out much faster than it used to
No noticeable growth in over a year
White salt crust forming on the soil surface (fertiliser residue accumulation)

If two or more of these apply, it’s time.

What You’ll Need

New pot: 5–10cm larger in diameter than the current one (a dramatically oversized pot holds excess moisture and risks root rot)
Quality indoor potting mix — general-purpose or species-specific
Small trowel or spoon
Clean scissors (wipe the blade with alcohol before use)
Watering can
Newspaper or a waterproof sheet for the floor

On soil: Garden soil is too dense for containers — it compacts and prevents root aeration. Use indoor potting mix; for most large plants, mixing in some perlite (roughly a 3:1 mix-to-perlite ratio) improves drainage significantly. For drought-tolerant species like Money Tree and Madagascar Dragon Tree, lean heavier on the perlite.

Six Steps for Repotting

Step 1

Stop watering 3–5 days beforehand. Slightly dry soil holds together better and makes removal easier.

Step 2

Lay the pot on its side and tap the sides and base to loosen the root ball. Hold the stem base with one hand, the pot with the other, and ease it out gently. Never pull hard — you can snap roots.

Step 3

Inspect the roots. Remove with clean scissors: black or brown mushy roots (rotten), excessively long circling roots (root-bound), anything dry or dead. A dusting of cinnamon powder on cut surfaces acts as a low-cost natural antibacterial.

Step 4

Prepare the new pot. Add a 2–3cm layer of clay pebbles at the base for drainage, then a layer of fresh soil. The new pot must have drainage holes — no exceptions.

Step 5

Position the plant centrally at the same depth as before. Fill around the sides with fresh soil, pressing gently without compacting.

Step 6

Water thoroughly until it drains from the base. Move the plant to a cool, well-ventilated spot for 3–5 days before returning it to its usual position. Recovery time matters.

Spring Pruning While You’re At It

Spring repotting is a natural occasion for a light prune — you’re already handling the plant, and it’s entering its growth phase.

Pruning Principles

Remove clearly yellowed leaves and dead stems first. Then thin overcrowded branches for better airflow. Shape for aesthetics last. Never remove more than one-third of the plant in a single session. Cut just above a growth node, at a slight angle.

Species Notes

Money Tree — Remove yellowed compound leaves; cut at the leaf stalk base. New buds emerge from nearby nodes.

Fiddle-Leaf Fig — Remove lower leaves; top-prune to encourage branching. Cuttings can be rooted in water.

Madagascar Dragon Tree — Remove dry lower leaves. Naturally forms a palm-tree silhouette as lower leaves drop.

Monstera — Remove ageing lower leaves. Aerial roots can be tucked back into soil or guided to a moss pole.

One Last Note

The most common repotting error is choosing a pot that’s far too large “so I don’t have to do it again for years.” A 5–10cm increase on the current diameter is correct. A dramatically oversized pot holds excess moisture around the roots and invites rot — the opposite of the outcome you’re working towards.
