Croton soil
Use a well-drained, humus-rich mix for Codiaeum variegatum. For an indoor container, choose a peat-free loam-based potting mix and keep outdoor soil separate.
Check how the mix holds water and air
Best soil mix
Use a well-drained, humus-rich mix. For a protected indoor or under-glass container, choose a peat-free, loam-based mix.
Keep a clear drainage path and let the mix become occasionally dry rather than leaving croton roots in stagnant water. Good drainage does not mean a permanently dry root ball.
Separate indoor and outdoor advice
Match the mix to the pot and setting
Use the peat-free loam-based direction for a protected indoor or under-glass container. Outdoor tropical planting is related context, not a reason to put a houseplant in unmanaged garden soil.
Use an exact target only when one is known
Soil pH
No validated numeric pH target is provided for an indoor Codiaeum variegatum container. Do not infer pH from leaf color or add amendments without a measured need.
Check the pot, watering and roots too
When soil alone is not the problem
