Recommended Spacing for Magellan Series Zinnia
My attempt to grow a few zinnias in the house was only moderately successful, at best.
I'd like to direct seed the Magellans that I got from Vesey's. Their website says to plant them 6-12 inches apart. We all know there's a big difference between 6 and 12 inches when it comes to plants.
I like my flowers to be fairly tightly spaced, but I understand they're suseptible to mildew.
What would you recommend for spacing?
