FAQ
Can russelia grow under a regular LED bulb?
A household LED gives some light, but a full spectrum grow light is brighter plus easier to aim. Missouri notes LED plant lights can emit the red plus blue light plants need. Hang the lamp 6 to 12 inches above the tips of russelia for useful light.
Should the light run all night?
No. Maryland advises no more than 16 hours of light in total each day plus notes too much light can turn leaves pale plus brown. Missouri notes 16 to 18 hours suits plants with no window light. A plug in timer gives russelia a steady day length.
How often should a hanging russelia be watered?
NC State notes russelia does well in average, well drained soil with medium moisture, while established plants handle dry soil. Water a hanging pot when the top inch feels dry. Baskets dry faster than pots on a shelf, so check them often, mostly under a warm grow light.
Do plants need a dark period?
Yes. University of Maryland Extension notes most plants require a period of darkness to develop properly. It advises lighting them for no more than 16 hours each day in total, especially when artificial light adds to window light. Set a timer so the lamp switches off at the same time each night.
What should I do with russelia in spring?
NC State advises cutting the stems of overwintered russelia to soil level in spring plus placing the plant outdoors once nights stay above 41°F. Fresh stems grow back to cascade from the basket. Move it to full sun outdoors for summer plus bring it in again before cold weather.
