Keep plugs moist until they are ready to transplant. To get the plants to bulk up before winter, increase their day length and do not allow them to flower. One of the most notable signs of Aster Yellows is deformed flowers. Affected plants generally show yellowing of the leaves, reddening, and stunting in the early stages of disease development. Echinacea are susceptible to Aster Yellows disease, which is caused by a phytoplasma transmitted by the six-spotted (aster) leafhopper. If conditions are favorable they can be susceptible to Botrytis, Rhizoctonia and Pythium. Many of these insects carry plant viruses that can be transmitted to Echinacea. Scout for whitefly, aphids, thrips and many types of caterpillars. An 11-14 week cold period will increase the number of flowers and overall quality of Echinacea.
