1. Space plants 10-14" apart in full sun or partial shade.
2. Water regularly, especially during the first year, as the plant establishes a root system. Water more often in a sunny location or less often in a shady spot.
3. Cut back in the fall or remove damaged foliage in spring. Deadhead flowers or cut them for a vase to encourage continued blooming.
4. Divide plants every three years.
5. Fertilize once a month during the growing season with an all-purpose fertilizer.
General Growing Tips For Your Seedling Tray
For best results with Ruby Bells, grow one seedling plug per 4-inch or two per 6-inch container. Use well-drained soil with a pH of 6.0-6.5, EC of 1.5-2.1 mS/cm SME, and medium feed (130-150 ppm N). Alternate using potassium-based and calcium-based fertilizers, avoiding high ammonium or nitrogen levels. Apply magnesium sulfate and iron chelate once or twice to prevent deficiencies. This plant requires bulking and vernalization for 6-10 weeks and 9-10 weeks, respectively. Provide temperatures of 60-65 during bulking and 55-60 during vernalization. During finishing, provide temperatures of 60-65 daytime and 60-62 nighttime. This plant requires long days to 14 hours. Don't pinch, and PGRs are typically not needed. Watch for aphids, whiteflies, pythium, and Rhizoctonia.
Flowering
Red flowers bloom on tall stalks from spring through summer.
Pinching
This plant doesn't require pinching.
Spacing
Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. We recommend spacing 4- or 6-inch containers of Ruby Bells seedling plugs 8-10" on center.
Height Control
Prevent stretching by providing consistent, moderate water and avoiding excess nitrogen and ammonium. Don't pinch to control height but use a spray of paclobutrazol at 15 ppm if necessary.
Pests
Scout for aphids and whiteflies as part of your Integrated Pest Management program. Prevention is the best method for controlling pest infestations.
Aphids are small, soft-bodied insects that cause damage by sucking sap from plant tissue. They reproduce quickly and are particularly attracted to young growth. Curling and yellowed leaves, stunted growth, and stickiness on leaves are signs of an infestation. These insects also spread diseases and reproduce rapidly. Use biological controls or horticultural oils to discourage and kill aphids.
Whiteflies are small, winged insects that eat plant sap and cause yellowed leaves and stunted growth. Severe infestations can lead to plants dying. Prevent infestations by sanitizing surfaces and tools and removing debris. Introduce natural predators and use sticky traps to control populations. Insecticidal soaps and oils are also effective against this pest.
Disease
Watch for signs of pythium and Rhizoctonia. Implement an Integrated Pest Management plan in your commercial greenhouse and take preventative measures against diseases. Water at the base of each plant in the morning, allowing the soil to dry between waterings. Provide good airflow in your greenhouse, and space plants to allow circulation and sunlight to the base of each plant.
Pythium and Rhizoctonia are fungal diseases that cause stunted growth, yellowed leaves, and plant death by eating away at the plant's roots. Use well-draining planting media and provide good airflow and spacing in your greenhouse. Allow the soil to dry slightly between waterings and apply fungicides with active ingredients abamectin, spinosad, or imidacloprid to combat these diseases.
Planting Ruby Bells Liners
We recommend planting one seedling plug per 4-inch or two per 6-inch container. Use well-drained soil and plant the ellepot evenly with the growing medium centered or evenly spaced in the container.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
