Why does your calla lily plant appear to be weeping tears?

Answer 1

The 'crying' is quite normal with calla lilies and while it often worries gardeners, there is nothing wrong with the lily.

Plant leaves contain small openings called stomatal and hydathodes.

The stomates are located on the upper and lower surfaces of the leaves while the hydathodes are located along the leaf margins.

Calla lilies must be kept moist during the growing/flowering stage of their life cycle. When this is done, the moisture makes its way up through the vascular tissue to these openings and bleeds out as droplets. It's commonly observed in the morning on lawns or anytime there is positive water pressure within the plant.

This is quite normal.

If anything, it shows that the lily has a well functioning vascular system.

FYI, the openings are used to transpire moisture. Water is taken up through the roots and travel up through the plants. 90% of the water taken up in this manner is simply "lost" to evaporation and the remaining 10% is used for tissue growth, etc. This evaporative action works like a pumping action which pulls liquid (and fertilizer ions dissolved in the liquid) up through the plant. This is how plant tissue function. When a plant grows in very moist conditions it can take up moisture and build up pressure inside the vascular cell walls. The openings are forced open and water may drip giving the appearance that the lily is crying.
