Campanula Pearl Deep Blue Seedling Tray

For best results with Pearl Deep Blue, plant one seedling plug per 4-inch or three per 10-inch container. Use well-draining soil with a pH of 5.5-6.5, EC of 1.0-2.0 mS/cm (2:1), and moderate feed (150-200 ppm N) of a NPK fertilizer with a ratio of 20-10-20. Provide temperatures at 60-65 daytime and 50-55 nighttime and don't pinch or use PGRs. This plant requires 12-14 hours of bright light daily. Watch for slugs, snails, Botrytis, Powdery Mildew, Pythium, Leaf Spot, and Fusarium Wilt. 

Blue bell-shaped flowers bloom from June through August.

This plant doesn't require pinching during finishing. Coach customers to pinch it back after the first blooms begin to die off to promote bushy, continuous growth.

Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant and easy access to scout for pests and water efficiently. We recommend giving 12-18" between containers and adjusting as needed for temperature, humidity, lighting, and your greenhouse layout. 

Control height and encourage bushy plants by providing adequate light (12-14 of hours bright indirect light) and growing seedling plugs in cool temperatures (60-65 daytime). These measures should keep Pearl Deep Blue from becoming leggy. You may use Bonzi or Sumagic according to the label instructions if necessary. Campanula is naturally bushy and dense, but you may pinch every few weeks once the plants are 3" tall if needed.

You may see slugs and snails in the garden or greenhouse. Watch for aphids and spider mites in the greenhouse. Implement a thoughtful Integrated Pest Management plan to prevent pests from damaging your seedling plugs. 

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.

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. 

Slugs and snails eat foliage in the garden or greenhouse. In the greenhouse, prevent damage by keeping snails and slugs away from plants with copper tape, bait, or natural predators. Although it's laborious, picking these pests off plants is effective. They most enjoy moist, dark areas, so keep the area around plants clean and free of debris and implement proper watering practices that allow the soil to dry between waterings and don't allow standing water.

Prevention is the best solution for pests! Use sanitary practices and provide adequate airflow and light and proper watering. 

Watch for these diseases with Pearl Deep Blue, employing preventative measures and acting at the first sign of infection.

Bacterial Leaf Spot is a disease that causes dark, water-soaked spots on foliage. It spreads rapidly in high humidity and causes defoliation and reduced health. Use proper humidity levels to prevent spread.

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.

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 using horizontal airflow fans to help control humidity levels. You may also use 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.

Root Rot is a disease caused by soil-borne fungi that destroys plant roots, causing the plant to wilt and die. Overwatering or growing seedling plugs in poorly drained soil can make its effects devastating for your crops. Allow soil to dry between waterings, provide adequate airflow and spacing, and grow seedling plugs in well-draining soil. 

We recommend planting one seedling plug per 4-inch or three per 10-inch container. Use well-draining soil and center or evenly space the ellepots in the containers.
