Pet-safety information is a general guide from the ASPCA's toxic-plant database and covers cats and dogs only. "If eaten" summarises the symptoms ASPCA lists for that plant; how an animal actually reacts depends on how much it ate and on the animal. It isn't exhaustive, isn't veterinary advice, and individual animals vary — never rely on it as the sole basis for a decision about your pet. If you think your pet has eaten a harmful plant, contact a vet immediately.

Common problems
Philodendron yellow leaves
Yellow leaves on a heartleaf philodendron are overwatering: the compost stays wet and the older leaves go soft and yellow first. Water when the top few centimetres are dry, every seven to ten days in summer, and make sure the pot drains. It tolerates being forgotten far better than being fussed over.
Philodendron brown tips
Brown, crisp tips are dry air or a plant that dried out completely and was then flooded. Even out the watering — a proper soak when the compost is dry, nothing between — and keep it out of the draught from a radiator. The tips stay brown; the next leaves come in clean.
Philodendron leggy with small leaves
Long gaps on the vine and small leaves mean it wants more light. A heartleaf philodendron survives in low light but grows properly in medium to bright indirect light. Move it closer to a window and cut the leggy vines back to a few leaves from the pot; it fills out from the cuts, and the trimmings root in water.
