Oregano Seedling Tray

For best results with Oregano, use one seedling plug per 4-inch container or three per 6-inch or larger container. Use well-drained soil with a pH of 5.8-6.2, EC of 1.0-1.5 mS/cm, temperatures of 65-70 daytime and 55-60 nighttime, and light feed (150-200 ppm N) with a supplement of Iron to improve foliage color. Pinch once, 5-10 days after transplant. We don't recommend using PGRs with herbs and vegetables. You may see aphids, mealybugs, spider mites, whiteflies, thrips, fusarium wilt, and pythium rot. 

White or pink flowers bloom in summer. Harvest as plants begin blooming for best flavor in culinary applications.

Pinch once, 5-10 days after transplanting.

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

We don't recommend using PGRs on herbs. Instead, promote bushy growth with pinching, adequate light, appropriate temperatures, and proper cultural practices.

Scout for aphids, mealybugs, spider mites, whiteflies, and thrips as part of your commercial greenhouse's Integrated Pest Management program. Prevention is the best defense against pests.

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.

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.

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.

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.

This plant isn't prone to disease but watch for signs of fusarium wilt and pythium rot. Implement 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, sanitizing tools, equipment, and surfaces, and spacing plants so sunlight and air can penetrate to the soil level of each container. 

Fusarium Wilt is a fungal disease that causes leaves to wilt and turn yellow. Use clean growing media and sterilize pots, trays, and tools before transplanting seedling plugs. Inspect plants regularly for signs of disease, checking roots and stems for discoloration and wilting. Remove and destroy infected plants to prevent the spread of fusarium fungus.

Pythium is a fungal disease that causes stunted growth, yellowed leaves, and plant death by eating away at the plant's roots. Use well-draining planting media and provide good airflow and spacing in your greenhouse. Allow the soil to dry slightly between waterings and apply fungicides with active ingredients abamectin, spinosad, or imidacloprid to combat this disease.

We recommend planting one seedling plug per 4-inch container or three per 6- or 10-inch container. Use a well-drained soil and evenly space or center the ellepot(s) in the container.
