BigBill said:If the plant is not growing well, where will the fertilizer go and how slow will it dissipate? So many plant growers, beginners mostly, operate under a false notion. Somehow fertilizer will cure a poor growing plant. It won't!!! Fertilizer supports good growth, it Does Not create it!
I have no idea as to exactly what your light is but "full light" is not the same as full sunlight!!
Here in SE Michigan, every corner downtown has Elephant Ears growing. The city dug them all up in mid November. In every single location
Gina1960 said:The thing with Elephant Ears is this. There are a lot of different kinds of 'elephant ears'. Its a catch all phrase. It can encompass Alocasias, Colocasias, Xanthosomas, Caladiums, Syngoniums, Arums, and other genuses of aroids. The most common ones sold for indoor use here are ALocasias and Syngoniums. Some do well indoors, some do not. Colocasias and Xanthosomas are not generally well suited to indoor use. Because Bill is correct. They thrive in full sun or at least half day sun with afternoon shade. Full OUTDOOR 360 degree morning sun with dappled shade in the hottest parts of the day in Florida are what make them do well for me. In overall cooler climates they can take more sun. They also thrive in humidity.
Do you know what you have? Is it an Alocasia? if so, what species or hybrid? That can tell you more about its requirements. Most Colocasia and many Xanthosoma can be grown in bogs or ponds. Alocasias can generally not. ALocasias and Xanthosomas can be trunk forming. Colocasias are generally not (although there are some exceptions).
Its difficult for me to tell from your photo, but your plant looks like a Colocasia to me.
Gina1960 said:OK yeah. Colocasias are not really houseplants. Plain green Colocasia escuelenta grows wild here in every ditch, bog, natural pond and manmade retention pond. Its on the Florida invasive list so no one here plants it on purpose. It thrives in full unadulterated all day sun, IN water (Its a running spreader that can take over a small body of water in nothing flat) needs no fertilizer and grows in the mud.
Its fancier cultivars like Mojito, Midori, Black Coral, Black Magic, Imperialis etc are planted ornamentally but again most people use them in wet parts of their yards or in ponds. No one grows them as houseplants because they are not suited for it.
If you want the big plants that look like trees that may make it in your house you need large growing Alocasias. Something like Portodora, Calidora, Odora.
