You Say Tomato; I Say Cucumber
I had a number of trays, and I was smart enough to label each set of seeds so I'd know what I had. For example, for the cucumbers, I put a big black "C" on the tray. And for the canteloupe, I put a big black "C" on the tray. So maybe there was a slight weakness in my system.
I thought I had them figured out, though, and I put the cucumbers beneath a trellis and the canteloupes in a spot with room to spread out. As you will have guessed, however, I mixed up the two.
I wondered why I couldn't get the plants beneath the trellis to climb.
