I have a small planter box with spinach seedlings. I can see the wind really knocks them around. Sometimes they are lopsided to one side, almost lying on the dirt. When this happens, I firm up the soil around them to stick them up a bit more.
I wanted to attach them to a planter box off the deck railing to save some space (as shown in picture), but it seems like the wind would be even worse up there.
Is there a way to protect them from the wind, or should I not be concerned about this? And is putting them on the deck railing a bad idea?
