The Q&A Archives: Indoor Geraniums

Question: Can dwarf geraniums be grown indefinitely under only fluorescent lighting?

Answer: Well, I don't know about indefinitely - after all, geraniums are living plants and all living things eventually must die. Geraniums are extremely popular plants to grow indoors and will bloom almost all year if they get direct sunlight and the temperature stays above 55F degrees at night. If you use fluorescent lights, use two 40 watt tubes (one 'daylight' and 1 'cool white' or two Gro-lite) to provide full-spectrum light. Keep the light source 6-12 inches above the plant. Enjoy!
