Dieffenbachia Sublime Rooted Cutting Liner

For best results with Sublime, grow one rooted plug per 6-inch container or two to three per 10-inch container. Use rich, well-drained soil with a pH of 6.0-6.5 and medium feed (200 ppm N with an N-P-K ratio of 3-1-2). Provide light at 2,500 fc and temperatures of 70-85 degrees. This plant flourishes in high humidity between 60-100%. Watch for scale, mealybugs, spider mites, root rot, and bacterial leaf spot. 

This plant is prized for its attractive foliage.

This plant doesn't require pinching.

Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. 

This plant doesn't require PGRs.

Scout for scale, mealybugs, and spider mites as part of your commercial greenhouse's Integrated Pest Management program.

Mealybugs are small, white, soft-bodied insects that feed on plant sap. They are covered in powdery wax, which gives them a cottony appearance. They reproduce and spread rapidly. Inspect plants regularly for signs of an infestation, including white, cottony masses on foliage. Always check new plants before bringing them into the greenhouse. Remove any highly infested plants from the greenhouse for quarantine or disposal. Introduce beneficial insects like ladybugs, lacewings, and parasitic wasps as biological controls for mealybug populations and apply insecticidal soap or horticultural oils to disrupt lifecycles and feeding. Maintaining a sanitary greenhouse and eliminating debris can deter pest infestations.

Scale are insect pests that feed on plant sap and look like small bumps on leaves or stems. Control damage from this pest by scouting, introducing natural predators, applying horticultural oils or insecticidal soap, and pruning and discarding infested plant parts or whole plants. Be sure to disinfect tools and always use a sanitary growing media and containers. Note that healthy plants are more resistant to pests and disease.

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.

Watch for signs of root rot and bacterial leaf spot. Take preventative measures against diseases in your greenhouse, including using sanitary tools, growing media, and containers; watering at the base of each plant; allowing soil to dry between waterings; and providing adequate space and airflow. 

Bacterial Leaf Spot results from a bacterial pathogen and causes water-soaked yellow or brown lesions on foliage. These may merge and cause leaves to turn yellow and drop. Prevent bacterial leaf spot by practicing sanitation and hygiene, watering 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.

Root Rot occurs in poorly drained or overly wet soil, which becomes the host for several types of fungi. It causes stunted growth, wilting, and root system decay. Prevention is the best treatment, and you will avoid most root rot problems by using clean, well-draining media, appropriate containers, and good watering practices for finishing seedling plugs. Inspect plants for signs of disease regularly. Repot infected plants in well-draining soil, adjust your watering schedule, provide better airflow, and use a fungicide if needed.

We recommend growing one rooted plug per 6-inch container or two to three per 10-inch container. Use rich, well-drained soil and completely bury the ellepot centered or evenly spaced in the container. Six inch pots are ready for retail sail in 12-16 weeks.
