Morning Glory Heavenly Blue Seedling Tray

For best results with Morning Glory Heavenly Blue seedling plugs, plant one per 4-inch container or two to three per 10-inch container. Use well-drained soil with a pH of 6.0-7.5, EC of 1.0-1.5 mS/cm, and medium feed (200-250 ppm N). Provide temperatures of 70-80 daytime and 60-65 nighttime with high light. PGRs and pinching typically aren't needed. Watch for spider mites, whiteflies, aphids, fungal leaf spot, and powdery mildew.

Blue flowers 2-3" across with white and yellow centers bloom from midsummer through fall.

This plant doesn't require pinching.

Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. We recommend 6-8" on center for 4-inch or 10-12" on center for 10-inch containers.

Use proper cultural practices to control the height of this vine in the greenhouse. Lower light intensity and cooler temperatures slow the growth rate of Morning Glory. Spacing plants adequately and providing sufficient (but not too much) water and fertilizer will prevent them from stretching.

Scout for spider mites, whiteflies, and aphids as part of your greenhouse's Integrated Pest Management plan. The best method of treatment for pests in the commercial greenhouse is prevention.

Spider Mites are tiny pests that cause stippling, yellowing, and webbing on foliage by feeding on plant sap. They flourish in warm, dry environments. Use correct water and fertilizing practices; over-fertilizing can attract spider mites. Proper humidity levels, predatory mites or ladybugs, and insecticidal soaps or oils may prevent or address a spider mite infestation.

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.

Watch for signs of fungal leaf spot and powdery mildew. Morning Glory isn't prone to disease but implement preventative measures in your greenhouse as part of an Integrated Pest Management plan. Water at the base of each plant in the morning, allowing the soil to dry between waterings. Morning Glory prefers dry, sandy soil. Provide good airflow and space plants so air and sunlight can penetrate to the soil level of each container. Use sanitary practices and clean growing media. 

Fungal Leaf Spot is a fungus-borne disease that causes water-soaked yellow or brown lesions on foliage, leading to defoliation and death. Fungal infection spreads via insects, splashing water, and contaminated equipment. Humid conditions create an inviting environment. Practice sanitation and good hygiene, water at the base of each plant, and space plants for adequate circulation and light penetration. At the first signs of infection, remove the affected leaves and treat the remaining plants with a copper-based fungicide like hydroxide, sulfate, oxychloride, or octanoate. Use fungicides carefully according to the label's instructions, and be aware that applying copper-based fungicides at high rates or during hot, dry weather can lead to phytotoxicity.

Powdery Mildew 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 horizontal airflow fans to help control humidity levels alongside 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.

We recommend planting one seedling plug per 4-inch or two to three per 10-inch container. Use a well-drained, sandy soil and completely bury the ellepot centered or evenly spaced in the container.
