Houseplants that were summered outdoors,
should be brought back inside when temperatures reach
around 50ºF. It is important to know your individual
plant’s temperature requirements. Ones that require
warmer temperatures can be brought in earlier, while
others may be able to tolerate even lower temperatures
and can be left outside longer. Oftentimes, by leaving
flowering plants outside during the early fall, the
temperature drop between day and night combined with
the shorter days will initiate blooming, creating a
burst of flowers during this time.
Fall is often a difficult and stressful
time for houseplants, so special care should be taken.
Plants will be exposed to colder temperatures, lower
light intensity and duration, and also much lower humidity
(especially for plants used to being outside during
the summer). This creates a great deal of stress for
the plants, which can leave them susceptible to pests
and disease. Be sure to know the signs of pest infestation,
and examine your plants closely. Any pest-infested plants
should be quarantined and treated immediately.
During the fall, plants may not need
to be watered as frequently due to the change in conditions.
Watering should be cut back if needed, or else root
rot may develop. Additionally, fertilizer should be
reduced during this time as well, as many plants will
not be actively growing. Some plants may even begin
to enter a dormant period.
By taking special care of your plants,
and maintaining their proper conditions, your houseplants
should be able to make it through this difficult transition
time in the fall.
