Repotting Large Houseplants: Step-by-Step Guide for Overgrown Containers

Large houseplants eventually need repotting or soil refreshment. Done correctly, they rebound quickly; done poorly, they suffer transplant shock.

When to Repot

Best time: spring (active growth beginning). Avoid repotting during budding/blooming. If too large to repot, top-dress annually: replace top 2-3 inches of soil with fresh mix.

Repotting Process

1. Prep: Water day before (damp soil holds rootball). Choose pot 1-2 inches wider. Mix potting soil with equal water in bucket.
2. Remove plant: Lay on side, slide out. Stuck? Knife around edge, pencil through drainage holes, gentle stem tug. Cut roots emerging from holes. Destroy pot if necessary (cut plastic, smash clay).
3. Prepare new pot: Moistened soil in bottom so rootball sits 1 inch below rim. Skip drainage stones—they waste soil space and don't improve drainage.
4. Root work: Loosen rootball, discard loose old soil (contains salts). Cut dead or circling roots.
5. Plant and water: Center plant, fill with moistened mix. Water thoroughly. Keep from direct sun 2 weeks.

Resume normal care after acclimation period.
