A few more tips when using pre-mixed potting media.
Even with pre-mixed pots, you still need to check that the pot has good drainage holes — because good drainage is still vital for root health.
When repotting or replanting, check the root system: if you see roots tangled and the potting mix is compacted, it should be replaced.
With a highly moisture-retaining potting mix: avoid watering too soon after the soil surface is still moist, to prevent root rot.
With a very porous growing medium: if the indoor environment is very dry, supplemental watering or using a spray bottle to increase air humidity is necessary.
Storing leftover growing medium: keep it in a dry place, away from moisture and mold, and in a sealed bag.
Monitor the plant for 2–3 weeks after replanting: if the leaves turn yellow or fall off excessively, the potting mix may not retain moisture enough or the plant may not be watered enough; if the plant stops growing or the roots turn brown, it may be due to excessive moisture or poor drainage.
