Philodendron 'Florida Beauty' problems — and how to fix them

Insufficient light is the main trigger. The variegation is chimeric and unstable, so move the plant to brighter indirect light and prune back fully green growth to encourage variegated leaves; there is no guarantee variegation returns on reverted stems.

Usually overwatering, poor drainage, or too little light. Check that the mix is drying between waterings and that the pot drains freely; the occasional old lower leaf yellowing is normal.

Typically low humidity or inconsistent watering, and sometimes fertiliser salt buildup. Raise humidity toward 60%, water more evenly, and flush the soil occasionally.

Caused by soggy, compacted soil and overwatering. Use a chunky aroid mix, ensure drainage, and let the top inch or two dry out; repot and trim mushy roots if rot sets in.

Common indoor aroid pests, favoured by dry air. Inspect leaf undersides and stems regularly and treat with insecticidal soap, neem, or a thorough wipe-down at the first sign.

Fungal or bacterial spotting from wet foliage and poor airflow. Remove affected leaves, avoid wetting the leaves, and improve air circulation to stop it spreading.
