First-Time Phalaenopsis Repotting: When, How, and What Mix to Use

Don't Repot While in Bloom

Correct instinct: wait until all buds open and flowers fall. Repotting during flowering risks bud blast.

Pot Selection

• Clear plastic preferred—roots photosynthesize; you monitor root health.
• Multiple large drainage holes essential.
• Orchid pots (slotted sides) excellent but not mandatory.

Ideal Potting Mix

• 20–25% charcoal
• 20–25% perlite
• 50–60% fir bark (or bark + tree fern)
• Commercial orchid mix usually has correct ratios.
• Critical: Sift out all fine dust; soak mix 1+ hours before use.

Repotting Steps

1. Unpot after flowering.
2. Remove all old mix; rinse roots.
3. Trim mushy/stringy roots.
4. Position in new pot, add wet mix, tap to settle.
5. Water thoroughly; drain completely.
6. Resume weekly watering + ¼ strength fertilizer.
