Plants should be allowed to dry moderately between waterings. Pythium and Phytophthora can be problems if the plants stay waterlogged for prolonged amounts of time. Pests/Disease: Thrips can be a problem as the plants begin to flower. Avoid late applications of slow release fertilizers. Note: for people that overwinter the Echinacea, keep the EC as close to 0 as possible when they are dormant. Allow the plants to dry moderately between watering as it is critical to maintain wet and dry cycles for overall plant health. It is generally recommended to do more applications at lower rates as opposed to higher rates with a single application.įertilizer/Watering: Supply a low-medium rate of constant liquid feed at 100- to 150-ppm of 20-10-20 fertilizer. It can sometimes cause distorted growth on leaves that are emerging at the time of application, but the plant quickly grows out of it.
PGRs: Configure has been observed to promote basal branching and should be used when bulking the plant in its vegetative state. Forcing is best done using daylength extension as opposed to night interruption. Putting plants that have already flowered under short days may induce dormancy. Photoperiods of over 16 hours of light are antagonistic to flowering, but do not stop it entirely. This can be achieved using natural short-days or black cloth. It is beneficial to bulk plants under short-days and then force flowering under long-day conditions. Echinacea is a facultative long-day plant with a critical day length of between 12 and 13 hours (depending on variety). Light: Provide 2,500 to 5,000 foot-candles of light. Temperature: Echinacea does well with 50 to 55☏ nights and 60 to 65☏ days. Media: Plant Echinacea in a well-drained media. A broad-spectrum preventative fungicide after transplanting is recommended – check labels for desired rates and application intervals, and (as with any chemical) test on a small group of plants before applying to the entire crop. The Soil (Garden) levels of the pot and the liner should match up evenly. Make sure not to cover the crown with Soil (Garden) by planting too deep incorrect planting depth is the most common cause for losses in Echinacea. Plant one liner per 4-inch or gallon pot.
Day-length extension up to 16 hours has proven beneficial for promoting flowering. Grow with 50° – 55° F nights and 55° – 65° F days. We recommend transplanting to a 4″ pot from a plug, not a larger size container if you receive the plants in the fall. Plants shipped in fall require winter protection.
