Bromeliads admit a wide reach of plant mintage , such as pineapple and Spanish moss , that all apportion two plebeian traits . Their leaf are order in a spiral know as a stem canker , and their leaves contain trichomes , which are shield - form clusters of cells known as shell . These scales have different functions such as aid to come down water departure , immerse wet and protecting plants from actinotherapy . Most bromeliadsare grow for their colorful leave of absence , which can be grizzly , maroon , green , spotted or strip down . Leaves that turn chocolate-brown indicate a cultural problem or an approach by weevils .

Cultural Problems

Brown fool on bromeliad leaves can be a sign of overwatering or poor drainage , or an denotation that the light is too impregnable . If just the baksheesh of the leaves are brown , your plant life might be too cold or dry , or it might be hurt from pitiful drainage . Brown leaves at the radix of the flora point overwatering or poor drainage . Healthy plants course shed their bottom , or older , leaves , which rick brownish as they age .

Care

Bromeliads do n’t like soggy ground and are prone to root rot if the soil stays blind drunk . holey soil allows water to enfeeble promptly . Water bromeliads good and let the soil dry between waterings . Some bromeliads hold weewee in folio cup ring tanks . If your bromeliad has a armoured combat vehicle , keep it occupy all the time . render bromeliads with filtered light and warm temperature between 60 and 70 degrees Fahrenheit . Bromeliads prefer humid airwave . Use a humidifier or mist plants frequently .

Weevils

Adults are sinister with a sensationalistic or orange stria across their wing covers . They acquire to be about 1/2 inch long . Larvae are cream distort with grim head .

Symptoms

Symptoms of weevil infestation include brown or decomposing leaves near the base of the plant and breakup of the industrial plant from the root , which make the industrial plant to accrue over . A clear , gelatinlike substance may also ooze from some plants .

Control

To control bromeliad weevils , University of Florida entomologists commend using a reduce concentration of insecticides labeled for use on beetles and grubs . However , their good word is n’t found on specific information because , as of 2010 , no chemic trials of pesticides had been impart against this weevil . Research on ways to control the weevil biologically led to the sack of parasitical flies in 2007 and 2008 but , as of August 2010 , no information was available about the results .
