Orchids are one of the most popular flowering plants in Greek homes, holiday villas, and hotel lobbies — but they will slowly decline if left in the same pot for years. Repotting refreshes the growing medium, removes dead roots, and gives the plant the airflow it needs to flower reliably in our warm Mediterranean climate. The video above walks you through the process visually; the steps below give you the what, why, and how so you can do it confidently the first time.
When Does an Orchid Actually Need Repotting?
Most Phalaenopsis orchids need repotting every 18 to 24 months — not on a fixed calendar, but when the bark mix inside the pot has broken down into a soggy, soil-like mush. Fresh bark is chunky and free-draining; old bark holds too much moisture and suffocates the thick, fleshy roots orchids rely on.
Other clear signals: roots snaking out of drainage holes in every direction, the plant wobbling even though roots fill the pot, or visible grey-green roots turning brown and hollow. If you see any of these signs, it is time to repot regardless of when you last did it.
What You Will Need Before You Start
Gather a clean pot one size larger than the current one (transparent plastic pots are ideal because you can monitor root health without disturbing the plant), fresh orchid bark mix or a blend of bark and perlite, sharp sterile scissors or pruning shears, and cinnamon powder or a commercial fungicide to seal any cut root ends. Avoid potting soil — it retains too much water and will rot orchid roots within weeks.
If you are in Greece during summer, do the repotting in a shaded, cooler spot indoors. The heat and low humidity on a balcony in July will dehydrate freshly exposed roots before you finish.
Step-by-Step: How to Repot Your Orchid
- 1
Remove the orchid from its old pot
Gently squeeze the sides of a plastic pot to loosen the root ball, then slide the plant out. If roots have bonded to a ceramic pot, run a thin knife along the inside edge. Hold the plant by the base of the leaves, not by the stem, to avoid snapping the crown.
- 2
Shake out the old bark and inspect the roots
Shake or gently pull away all the old potting mix. Healthy roots are plump, firm, and white to silvery-green. Dead roots are brown, hollow, or papery — they will snap without resistance. If you are unsure, give a root a gentle tug; live ones hold firm.

Cut away dead and rotted roots
Use sterile scissors to cut off any dead, mushy, or hollow roots as close to the base as possible. Dust each fresh cut with cinnamon powder — a natural antifungal that stops rot from spreading. Do not be timid: removing dead roots is far less harmful than leaving them to decay alongside healthy ones.

Position the plant and fill with fresh bark
Place the orchid in the new pot so the junction between roots and stem (the crown) sits just below the pot rim. Trickle bark mix in around the roots, tapping the pot gently on the table to settle the medium without compacting it. Do not pack it tightly — the roots need air gaps to breathe.
- 5
Water lightly and place in bright indirect light
Give the pot a thorough soak under room-temperature water, let it drain fully, then place the orchid where it gets bright but indirect light — an east-facing windowsill or a shaded balcony works well in Greece. Hold off on fertiliser for four to six weeks while the roots recover; then resume a balanced orchid feed diluted to half-strength every two weeks.

FAQ
- Can I repot an orchid while it is still flowering?
- It is best to wait until the blooms have dropped. Repotting stresses the plant and it will often drop buds or flowers prematurely. If the roots are visibly rotting, however, repot immediately and accept that the current flowers may not last — saving the plant is more important.
- How often should I water after repotting?
- Wait until the top layer of bark feels dry and the pot feels light when you lift it — usually every 7 to 10 days in summer, less in winter. Newly exposed roots are more vulnerable to rot, so err on the side of underwatering for the first few weeks.
- My orchid's roots are growing out over the rim of the pot. Should I push them back in?
- No — aerial roots above the bark are normal and healthy for Phalaenopsis orchids. They absorb moisture from the air and do not need to be buried. Only repot if the bark inside has decomposed or the plant is clearly root-bound and unstable.
