CARE INFORMATION, PART I
This Page Last Updated: December 15, 2012
This is just a summary of the information we all more-or-less eventually learn in order to keep our plants alive and healthy.
There will not be a written or oral exam -- only your plants' survival will demonstrate your on-going grasp of this.

TREES AS INDOOR BONSAI HERE
Particular varieties that can tolerate the temperature and humidity of indoor conditions,
but which still demand LIGHT, good air circulation, and very good soil mix drainage in order
to be healthy and to thrive. LIGHT is the key, LIGHT is the main course; fertilizer is only a supplement.
Small-leaf or needle-leaf varieties indoors usually cannot get enough light for photosynthesis. Use either bigger-leaf
varieties and/or more natural and artificial light: full-spectrum fluorescent bulbs (T-8's are energy-efficient also) can be put closer to the plants than
heat-emitting incandescents. South and west-facing windows are better than northern exposures; garden
window boxes and skylights are very helpful. Occasional outdoors warm-weather, wind-protected, and partial sun-screened
sessions for indoor plants are appreciated by them -- just be sure to monitor their need for additional water then.
Tropicals brought outside on occasion need to be kept inside when outdoor nightly temperatures are consistently
in the 50s.
