Hypoestes Splash Select Rose Seedling Tray

For best results with Splash Select Rose, grow one seedling plug per 1801 cell or three to four per 4-inch container. Use well-drained soil with a pH of 5.5-6.0, EC of 1.0-1.5 mS/cm, and low feed (100-175 ppm N). Provide temperatures of 65-75 daytime and 62-65 nighttime and low light (400-500 fc). Growing this plant under high light conditions causes the leaves to curl. Don't pinch or use PGRs. Watch for spider mites, whiteflies, aphids, leaf spot, powdery mildew, and root rot. 

This plant may develop flower spikes in summer, but most gardeners grow it for its stunning foliage. Cut back the flower spikes when they appear. 

This plant doesn't require pinching.

Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. We recommend spacing 4-inch containers of Splash Select Rose seedling plugs 6-8" on center.

Use a spray of daminozide and chlormequat chloride in a tank mix at 1,000/500 ppm.

Scout for spider mites, whiteflies, and aphids as part of your commercial greenhouse's Integrated Pest Management plan.

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.

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.

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.

Watch for signs of leaf spot, powdery mildew, and root rot. Use preventative measures in your greenhouse. Water at the base of each plant in the morning, allowing the soil to dry between waterings. Provide good airflow and space plants to allow sunlight to penetrate to the soil level of each plant. 

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.

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.

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 seedling plug per 1801 cell or three to four per 4-inch container. Use well-drained soil and center or evenly space the ellepot, completely burying it in the container.
