Bracteantha Granvia White Rooted Cutting Liner

For best results with Granvia White, plant three rooted liners per gallon container. Use a well-drained soil with a pH of 5.8-6.2, light feed (200 ppm N), and temperatures of 65-76 daytime and 56-61 nighttime. Control growth with a Bonzi spray or drench and a Sumagic spray. You may see thrips, aphids, and whiteflies. Stem and root rot can be a problem. Apply a fungicide drench at transplant. 

White flowers bloom from May through September.

This plant doesn't require pinching.

Space containers for adequate airflow around the base of each plant and to allow sunlight to penetrate to the soil level.

Use Bonzi spray at 20-30 ppm, Bonzi drench at 2-3 ppm, or Sumagic spray at 10-20 ppm. 

Scout for aphids, thrips, and whiteflies as part of your Integrated Pest Management program.

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.

Thrips are tiny insects that eat plant tissue and can transmit viruses. Watch for silvery-white streaks or black spots on foliage and distorted growth. Use natural predators (like predatory mites), insecticidal soap, neem oil, and sticky traps to control infestations and prevent spread.

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.

This plant can be prone to stem and root rot. Take the following general precautions in your commercial greenhouse as part of an Integrated Pest Management program:

Apply a fungicide drench at transplant. Water at the base of each plant in the morning and allow the soil to dry between waterings. Provide good airflow in your greenhouse. We recommend using horizontal airflow fans. Space containers for airflow and sunlight to reach the base of each plant.

Stem Rot is a fungal disease that causes wilting, browning, and death of plant stems. Prevent infection with proper sanitization, adequate drainage, and good airflow. Don't overwater, and allow the soil to dry slightly between waterings. Maintain appropriate temperatures and humidity levels in the greenhouse and grow disease-resistant plants. Regularly check plants for signs of disease and remove and destroy infected plants to prevent spread. Apply a fungicide if necessary.

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 three rooted plugs per gallon container. This plant won't do well in 4-inch containers or 1801s. Use a well-drained soil and completely bury the ellepots evenly spaced in the container.
