Frosted windows and indoor plants
Hi I have just moved to an apartment with no balcony or outdoor space. There are large windows on the East and West facing sides of the building; the east side lets in a lot of light, however, the windows on that side are frosted glass. I have 2 small potted citrus trees - if I place them by the east facing frosted windows will they get enough light? Or considering my new space restrictions, should I find new homes for the trees and look for other plants that would do better indoors with frosted windows? Thanks!

Thank you for using Ask an Expert. I think your citrus tress will be fine in the frosted windows as it will still receive the defused light that it needs to grow.
Citrus trees grown indoors require a loose, well-drained potting mix maintained at a 5.5 to 6.5 pH.
High humidity also is required in the 30 to 60 percent range. Most homes have an average humidity of only 15 to 20 percent, so a cool mist vaporizer or humidifier may be used.
Alternatively, placing the container on a pebble tray that is partially filled with water and misting the foliage frequently helps raise the humidity.
Apply a soluble citrus fertilizer formulated to maintain the medium at a slightly acidic pH once a month or use a slow-release fertilizer.
Trees require water when the top 2 to 3 inches of potting medium feels dry. Over-watering is a common cause of fruit drop.
I hope this information is helpful to you. Good Luck!
