It’s hard to know exactly why this happened, but unfortunately it can and did. One reason is when zinnias are overcrowded (planted too close together) they can become stunted and produce smaller flowers. If that is not the case, they may not be getting the necessary amount of sun or it may have to do with the conditions either around planting time or during the growing season. Don’t be discouraged though, as we have all had growing seasons where things just don’t go as planned.
