General Growing Tips For Your Seedling Tray
For best results with Husker Red Superior, plant one seedling plug per 4-inch container or two to three per 6-inch container. Use a well-drained soil with a pH of 6.0-7.5, EC of 1.5-2.5 mS/cm, and light feed (150-200 ppm N). Maintain temperatures of 68-75daytime and 60-65 nighttime. This plant doesn't require pinching or vernalization during finishing. Provide high light intensity, around 4,000-6,000 fc, and use B-Nine or Bonzi if needed. Move plants outdoors for more light intensity once temperatures are above 50 degrees at night. This plant resists pest and disease, but root rot can develop in poorly draining soil or overly wet conditions.
Flowering
Pinkish-lavender flowers bloom in May and June.
Pinching
This plant doesn't require pinching.
Spacing
Space containers for adequate airflow and sunlight penetration around the base and foliage of each plant. We recommend spacing 4- and 6-inch containers 6-8" on center and 10-inch baskets 12-14" on center.
Height Control
With proper temperatures and lighting, this plant doesn't typically require PGRs. However, Husker Red Superior responds well to B-Nine or Bonzi. Use chemical growth regulators according to the label instructions.
Pests
This plant isn't prone to pests.
Disease
Watch for root rot in overly wet conditions. Use a well-draining media and water at the base of each plant in the morning, allowing the soil to dry out between waterings. Provide good airflow in your greenhouse and space plants so sunlight can reach the soil level of each container.
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.
Planting Husker Red Superior Liners
Plant one seedling plug per 4-inch container or two or three per 6-inch container. Use well-drained soil and completely bury the top of the seedling plug centered or evenly spaced in the pot. Six-inch containers finish in 10-12 weeks.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
