Although tropical corn plants are nontoxic to humans, they are poisonous to pets, including dogs and cats. Tropical corn plants contain toxic compounds called saponins that cause can cause symptoms such as vomiting with blood, depression, anorexia, excessive salivation and dilated pupils (especially in cats.)
Consequently, why are my corn plants leaves turning yellow?
The solution is to side dress with a high nitrogen fertilizer. Cool weather can also make corn plant leaves turn yellow. Again, this is due to a lack of nitrogen. When soil is cool and wet, the corn has trouble absorbing nitrogen from the soil.
How often do you water a dracaena plant?
Dracaena is a relatively drought-tolerant plant and adoesn't appreciate soggy soil. Water only when the soil feels slightly dry, and then water generously, using tepid water, until water trickles through the drainage holes. Empty the drainage saucer after about an hour and never allow the pot to stand in water.
