this buildup, be sure to water houseplants until the water comes out
of the drainage hole(s) every time you water. It is easiest to put
smaller pots in the sink or bathtub and water them there. Use a
turkey baster to empty the saucers of plants too large to move so
they do not sit in the drainage water. Otherwise, the soluble salts
will be reabsorbed as the soil takes up the water in the saucer.
Drainage hole in flower pot
grow in the same pot for a long time should be leached every six
months or so by running water equal to twice the volume of soil
through the pot. If salt has accumulated on the top of the soil,
remove the top 1/4-inch of soil before you
Be careful not
to overfertilize houseplants. As a rule of thumb, do not fertilize
them at all through the winter months when they receive less light
and are not actively growing. Use a water-soluble fertilizers such
as Miracle-Gro or Peters formulations from April through September.
Once a month should be more than adequate for most foliage
houseplants. Use a balanced formulation such as 20-20-20.
Those grown for
their flowers should be fertilized more often, perhaps every two
weeks. Be sure to use a formulation with a higher phosphate (the
middle number) content to avoid pushing vegetative growth at the
expense of flowers.
