This study was performed during a three year period, 1969-1971. The first year the writer evaluated containers, soil mixtures, planting dates, fertilizers, and temperatures for optimum petunia production. The data collected aided in selecting the best greenhouse procedures for future studies. The second year three bedding plant varieties were used for further evaluate containers and soil mixtures using direct seeding and transplanting and watering continuously or watering as needed.

As a result of the first two year's studies, a liquid fertilizer (10-5-5), an average temperature of 75 F, Jiffy-7 peat pellets, plants not receiving continuous water program was used for the third year's study. Optimum plant production and some marketing was performed the third year. Direct costs were kept and evaluated as to profitability.
