minimum temps for houseplants


Question
QUESTION: Hi Tracy!

we recently had our screened in porch enclosed so it's going to remain dry for the winter.  on a sunny day it can get to about 70 degrees out there, but the temps go down at night.  here's my question:

what are the minimum temps for pothos, jade plants and cheerlead in order to survive?  my spider plants last all winter in the garage with available light.  we live in new jersey; I'm not sure of our zone - maybe 6.

i look forward to hearing from you.  thanks in advance!

regards,
abby

ANSWER: Hi Abby,
  Pothos are comfortable in the same temperature range indoors as most people are. Just like us, they get a bit chilly below 60?and warm above 75?

The jade plant can tolerate temperatures that range from very cool to very warm. Jade can tolerate temperatures that dip to about 50 to 45 degrees Fahrenheit.

I am not familiar with what you called a Cheerlead plant. It may not be a correct common name or botanical name for the plant you are asking about. The research I did on it as well as asking both of the 'plant gurus' I turn to when I come across something I don't know came up with nothing by that name but a kind of tree and a type of endangered clover that grows only in ponderosa pine woods in Washington state. If you find out what the correct name for the plant is or send me a picture of it so I might be able to better identify it then I can tell you the lowest temperature that plant can tolerate.

I hope this helps. If you have any questions or need additional information please don't hesitate to ask.
         Thanks
         Tracy

QUESTION: dear tracy,

Answer
Hi Abby,
  Scheffleras are somewhat sensitive to temperature and humidity. They are native to regions that are warm and wet, so it is good to try and replicate this for your plant. It is best if temperatures stay around 70F during the day and don抰 go below 60F at night. Keep the plant away from drafty areas like doorways and radiator vents.

Schefflera grow best in bright, indirect light. A curtain filtered east facing window or curtain filtered west facing window is ideal. Schefflera can also be set about 2-4 feet away from a south facing window. Do not set a Schefflera directing in a south facing window. That much direct sunlight could scorch the leaves and the heat generated in a south facing window will cause a Schefflera to wilt.

Schefflera like for their soil to be kept moist but not wet. Avoid letting plant sit in water.
Never allow the soil to dry out completely, this could be fatal to a Schefflera. Schefflera may or may not recover from allowing the soil to dry out completely even once.

Schefflera will grow leggy and out of shape if left alone and especially in low light conditions. Prune the plant regularly to keep it's shape. This plant will come back strongly after even a 'heavy' pruning.

It is common for a Schefflera to lose some leaves due to a change of environment and is not really a cause for concern unless the plant starts dropping leaves in great numbers.


Some common problems with Schefflera is the leaves turning black and falling off and wrinkled leaf tips. Leaves turning black and falling off is a sign that the plant is being over-watered. Wrinkled leaf tips is a sign the soil is being kept too dry.

Schefflera is also a favorite plant of spider mites. Carefully check the plant regularly for any sign of insects/mites. Regularly spraying the plant with a strong spray of water, especially the undersides of leaves, will help control insect/mites. It will prevent high populations of insects/mites from developing by washing off any insects or mites that may be on the plant.
Very warm, dry conditions are a perfect environment for spider mites. Raising the humidity around the plant by grouping it together with other plants or setting the plant on a tray of pebbles and water will help prevent spider mites. Regular misting may also help.
