Repotting Houseplants: Step-by-Step Guide for Healthy Transitions

Repotting keeps houseplants healthy by refreshing soil and giving roots room to grow. Whether moving to a larger pot or top-dressing a mature plant, proper technique ensures a smooth transition.

Choosing Pots & Soil

• Use plastic pots with peat-based compost (or species-appropriate mix).
• Soak clay pots 24 hours before use to prevent moisture wicking.
• Common sizes: 6, 8, 13, 18, 25 cm. Leave rim-to-soil space for watering—larger pots need more space.

For large, unrepottable plants: top-dress by removing top 1–1.5 inches of old compost and replacing with fresh, avoiding root damage.

Repotting Steps

1. Water plant the day before.
2. Invert pot, tap rim on firm surface to release root ball. Loosen with knife if needed.
3. Inspect roots; remove crock (drainage shards) from base. Tease roots free.
4. Select a clean pot 1–2 sizes larger.
5. Add handful of fresh compost to base. Center root ball, keeping its surface below rim.
6. Fill around roots with compost—don’t pack tightly; roots need room to grow.
7. Top off if needed, firm gently, leave watering space.
8. Water thoroughly, drain excess, place in decorative outer pot.
9. Wait until compost surface shows dryness before watering again.

Repot annually for young plants, every 2–3 years for mature ones. Your plants will reward you with vigorous growth.
