General Growing Tips For Your Seedling Tray
For best results with Juncus Effusus Spiralis, grow one seedling plug per 1801 cell or 4-inch container or one to three per 6-inch or gallon container. Use well-drained soil with a pH of 5.5-6.2, EC of 1.2-1.5 mS/cm, temperatures of 62-74 daytime and 59-64 nighttime, and moderate feed (175-225 ppm N). Use a nitrate-based fertilizer with low phosphorus and don't use too much ammonia or a nitrogen fertilizer. This plant doesn't require pinching or PGRs. Be careful not to bury plugs too deeply at transplant. Watch for root rot and aphids.

Pests
Scout for aphids as part of your greenhouse's Integrated Pest Management program. Prevention and early intervention are the best methods of pest control.
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.
Disease
Juncus Effusus Spiralis isn't prone to disease. Root rot can occur in overly wet conditions. Use well-draining soil, water at the base of each plant in the morning, and provide good airflow in your greenhouse.
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 Juncus Effusus Spiralis Liners
We recommend growing one seedling plug per 1801 cell or 4-inch container or three per 6-inch or gallon container. Use well-drained soil and center or evenly space the seedling plugs in the containers.
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.
