A new Venus flytrap does not need repotting for at least a year. Repot only when the container condition calls for it rather than on an automatic annual date.
Venus flytrap repotting: when and how
Repot Dionaea muscipula only when the container needs it, using spring as the stated timing. Keep the Venus flytrap in a wet bog-style setup, not an ordinary houseplant pot.
Check the roots, mix and drainage
When to repot
If repotting is needed, do it in spring. No other season or fixed interval is established for Dionaea muscipula in this guidance.
Use the smallest practical size increase
Choosing the next pot
Keep the Venus flytrap in a container suited to a wet bog medium with drainage and a water saucer or reservoir. Choose the new pot for the existing root system rather than a large ordinary houseplant pot.
Move the rootball without unnecessary damage
How to repot
Use a specialist low-nutrient acidic carnivorous medium. Peat-free sphagnum moss is the named alternative. Do not add garden soil, standard fertilizer or an unverified houseplant mix.
Keep light, water and support steady
After repotting
After repotting, keep the medium wet from below with rainwater or distilled water, never let the plant dry out and do not fertilize. A reduced winter saucer level is also described for the Venus flytrap.
