Question -
I have a Rhoeo which thrived beautifully outside in a pot on the porch this summer.  I had to bring it inside because we live in the midwest, and we are having frost warnings at night.  It is already not looking as healthy (after 3 days).  We don't have any windows that receive direct sunlight.  Should I buy a grow light, and if so, what type?  How often should it be watered and fertilized?  All summer it was fertilized once a month.  Thank you for any advice you can provide.

Hi Joni,

Rhoeo is a sun-loving plant and yours is going through the doldrums now that it is deprived of direct sun. Of course, the best thing you can do is give it more natural light. Artificial light will help, but it will not be as effective as natural light.

I recommend an inexpensive fluorescent light that is placed within a foot or less of the top of the plant. Other bulb types generate a lot of heat and cannot be placed so close to the plant. Also, fluorescent lights are much more energy efficient and cheaper to operate. Keep the light on for 12-16 hours per day.

In reduced light, it is important to reduce your watering frequency and the fertilizer. Let the top inch of the soil dry out in between waterings. Stop fertilizing until next spring when you can move it back outside.

Thanks so much for such a quick response.  Where can I purchase this type of light?

Answer
Hi Joni,

Fluorescent lights are available in many sizes, shapes and forms. In fact, many lighting stores sell fluorescent bulbs that screw into standard light fixtures. Any fluorescent light will work fine. It does not have to be a special grow light.

Any store that sells lights will have fluorescent lights. Big Box stores like Home Depot and Lowe's have fluorescent lights. You can also find many online retailers.

Thanks for the terrific rating!
