Q.Did I hurt my morning glories?
I am new to gardening so I just found out about cotyledon leaves. My morning glories are just lil seedlings and I read something about pinching to make it more dense, so I tried it. But I didn’t know about the cotyledon leaves, BUT I DIDN’T TOUCH THEM. I ‘pinched’ what was I’m assuming the actual stem, not the cotyledon leaves. By doing this, did I risk anything? If I didn’t pinch the actual cotyledon leaves and just the baby stem, then I should be good, right?
For future reference, don't pinch back plants before they are 3-4 inches tall and has several sets of true leaves. What you've done is set back the emergence of true leaves which the seedling desperately needs for photosynthesis/energy. Does the seed have enough energy to overcome your rookie mistake? Only time will tell. This article discusses pinching and pruning of morning glories. https://www.gardeningknowhow.com/ornamental/vines/morning-glory/prune-morning-glory-plants.htm
