I have a new question. I'm planning a 4' by 14' zinnia bed out front next spring for Z. haageana and several varieties of Z. elegans. How many actual seeds would I need to plant that (direct sown) if I intend to do heavy culling?
Would planting them 4" apart with the intent to cull every other one (or more) be feasible? I don't want to overcrowd or waste space, but the intention of heavy culling is what's throwing my planning off because 4" could easily become 12".
