Kalanchoe Thrysiflora Rooted Cutting Liner

For best results with Thrysiflora, plant one rooted liner per 4-inch or two to three per 10-inch container. Use a well-drained mix of peat, sand, and perlite with a pH of 6.0-7.0, EC of 1.5-2.5 mS/cm, medium feed (150-200 ppm N), and temperatures of 70-75 daytime, and 60-65 nighttime. Pinching may promote branching but will delay finishing time. Don't use PGRs. Supply 5,000-7,500 fc of light. Water thoroughly and then allow the soil to dry completely before watering again. With no overwatering, any disease is rare among this plant. Watch for powdery mildew and root rot. You may see mealybugs and spider mites. 

Small yellow flowers bloom on tall stalks in late winter to early spring in perennial zone 10-12.

Pinching can promote branching but delays finishing time.

Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. We recommend spacing 4-inch containers of Thrysiflora 6-8" on center and 10-inch containers 12-18" on center.

This plant doesn't require PGRs. Promote compact growth by providing adequate light and proper fertilizer rates.

Scout for mealybugs and spider mites as part of your greenhouse's Integrated Pest Management plan. Prevention is the best way to control pest infestations. 

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.

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.

This plant isn't prone to disease. In overly wet conditions, powdery mildew and root rot can develop. Use preventative measures in your commercial greenhouse, including watering at the base of each plant in the morning, allowing the soil to dry between waterings, providing good airflow, and spacing containers for sun and air to reach the base and foliage of each plant. Additionally, use a mix of peat, sand, and perlite media to grow this rooted liner. 

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 rooted plugs.

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 planting one rooted liner per 4-inch or two to three liners per 10-inch container. Use a well-drained mix of peat, sand, and perlite and completely bury the ellepot centered or equally spaced in the container.
