Step 1: Field History
Flats of annuals are purchased from a number of different local greenhouse operations. There is no specific greenhouse that the affected plants are coming from. Flats tend to get moved around quite a bit because of changing seasons, new, more colorful stock coming in, and aesthetic reasons. Most all annuals are planted in soilless mixes with either a peat or coir base and added vermiculite and perlite. Depending on the variety of plant, the proportions of the mix could vary.
