3. Water Illumination Scarlet regularly, once or twice a week, or more often in drought.
4. Fertilize once a month during the growing season with a balanced, all-purpose fertilizer.

General Growing Tips For Your Seedling Tray
For best results with Illumination Scarlet, use one seedling plug per 4-inch or three to five per 10-inch container. Use well-drained soil with a pH of 6.0-6.5, EC of 0.6-0.9 mS/cm (2:1), average daily temperatures of 65-72, and medium feed (150-200 ppm N). Provide light at 4,000-6,000 fc, and don't pinch. This cultivar requires long days to bloom and will respond to Cycocel as needed. Watch for aphids, thrips, powdery mildew, and botrytis.
Flowering
Scarlet flowers bloom in summer.
Pinching
This plant doesn't require pinching.
Spacing
Space containers to allow for airflow and sunlight penetration around the base and foliage of each plant. Illumination Scarlet does well with 6-8" between containers; adjust spacing as the plants grow. Proper spacing helps prevent the spread of pests and diseases, encouraging healthy roots and foliage.
Height Control
Illumination Scarlet will respond to Cycocel at 250-500 ppm if needed. Follow the label's instructions. Provide sufficient light, warm temperatures, and appropriate spacing to prevent plants from becoming leggy and encourage healthy roots and strong starter seedling plugs.
Pests
You may see aphids and thrips. Carefully scout for pests regularly in your greenhouse and implement an Integrated Pest Management plan.
Aphids are small, soft-bodied insects that cause damage by sucking sap from plant tissue. They reproduce quickly. Curling and yellowed leaves, stunted growth, and stickiness on leaves are signs of an infestation. Use biological controls or horticultural oils to discourage and kill aphids.
Thrips are tiny insects that eat plant tissue and can transmit viruses. Watch for silvery-white streaks or black spots on foliage and distorted growth. Use natural predators (like predatory mites), insecticidal soap, neem oil, and sticky traps to control infestations and prevent spread.
Follow label instructions with any insecticides or pest control products.
Disease
Watch for Botrytis and Powdery Mildew with Illumination Scarlet seedling plugs. Use preventative care and an Integrated Pest Management plan to stop the spread of disease in your greenhouse.
Botrytis is a common fungal disease that causes brown spots on stems, leaves, and flowers. Remove and destroy affected plants, maintain appropriate humidity levels, and apply fungicides with boscalid, fenhexamid, or iprodione to control the spread.
PowderyMildew is a fungal disease that thrives in humid conditions, appearing as a white or gray coating on foliage and flowers. Provide good airflow in your greenhouse. We recommend using horizontal airflow fans to help control humidity levels, along with a dehumidifier or manual venting. Remove and destroy infected plants and apply fungicides as needed or preventatively. Look for the active ingredients myclobutanil, trifloxystrobin, or potassium bicarbonate to combat Powdery Mildew threatening your seedling plugs.
With any disease, take action at the first sign to prevent irrevocable damage. Carefully follow all label instructions for any fungicide or chemical control in your greenhouse and consider every factor when choosing a treatment option as part of IPM.
Planting Illumination Scarlet Liners
We recommend planting one seedling plug per 4-inch container, or three to five per 10-inch container. Use well-drained soil and completely bury the ellepot in the center 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.

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.
