Not only is peace lily harmed or killed by freezing temperature levels, it is additionally conscious chilling temperatures above freezing. Although the plant has actually long been believed to be fairly resistant to cooler temperatures compared to various other exotic foliage plants, a study by members of the University of Florida’s Environmental Horticulture department revealed that peace lily can be harmed by temperatures from just over 32 degrees Fahrenheit to 59 levels Fahrenheit. The quantity of damages plants experienced depended upon the size of the plant, the maturity of the fallen leaves and also the amount and duration of the cold.

What kind of damage from the cold?

The damages began at the fallen leave tips as well as spread inwardly, with soft, brownish areas turning black and afterwards drying up. Mature fallen leaves suffered greater than younger leaves. Some plants passed away. The level of damages depended upon the cultivar. Furthermore, extended exposure caused higher damage. Peace lilies treated with 45 level Fahrenheit temperatures likewise revealed damage, but less than that of the plants given colder temperatures. The cultivars “Annette” and “Debbie” revealed one of the most resistance to chilly damage, with “Viscount” and also “Classic Viscount” revealing intermediate resistance.

Slowing of growth in the cold

Peace lilies subjected to 52 level Fahrenheit temperature levels for five to 10 days really did not reveal any type of noticeable damage, yet they were still impacted by the cold in the University of Florida research. Their development price slowed appreciably for as long as 45 days regardless of having ideal temperature levels as well as nourishment adhering to the cool direct exposure. As a whole, peace lily makes it through at temperatures in between 40 as well as 100 degrees Fahrenheit, however, for best development, maintain your peace lily in between 68 and also 85 levels Fahrenheit during the daytime as well as 10 levels cooler in the evening.
