“Mother-in-Law’s Tongue” and an Orchid plant.
There is a white “fungus” looking on the top of their soil. WHAT can I do to get rid of it? Am I watering too much? Indoors all the time.
this might be either a salt accumulation from using Las Vegas tap water coming
from the Colorado Rivere or it could be fungus (mycelial growth) on the
surface. Water taken from Lake Mead (Colorado River) at the Las Vegas location
is carrying about six pounds of salt for every thousand gallons of
water.
Our native desert soils also contain alot of salt. I assume your
houseplants were potted with some commercial potting soil so the salt load is
probably relatively smaller than our native desert soils. Over time this salt
can accumulate in the soil (from the tap water and soil salt) and wick back to
the surface of the soil as the water in the soil evaporates. This can leave a
white crust on the surface.
Salt deposited on the soil surface from the Las Vegas water coming from Lake Mead and soil salts left behind when the water evaporates. |
Remove the upper layer of the soil and repot the
plant with fresh garden soil. Dilute your tap water with about 3/4 of the
volume with distilled or RO water. I would not use pure distilled or RO water
as this might cause some problems with your potting soils. Also when you water,
make sure 1/5 of the water applied actually leaves the container out the bottom
as drainage and discard. This helps to flush out the soil salts.
some fungal growth. Not all fungi are bad and some are decomposers and work to
help break down organic materials that are already dead. Seldom do these fungi
that feed on dead things attack healthy plants. Scrape off th surface, repot,
keep air circulating around the plant and in sunlight when possible to help
keep these fuzzies to a minimum.
