Today was transplant day, which means that I carefully moved 36 tomato seedlings to their new pots. This isn’t difficult, but it is tedious. Also known as pricking out, transplanting is an important step in growing plants from seed.
I started by filling three dozen three inch pots with sterile, slightly moist potting soil. Each pot needed a marker to indicate which tomato it held, so I cut 36 tags from a plastic yogurt tub and labeled each one.
After making a deep hole in the soil of the new pots, I carefully lifted each tomato plant from the bottom using an escargot fork (and you thought you didn’t have any use for an escargot fork?). I only touch the seedlings on their cotyledon leaves, as damage to the stem or first set of leaves can stunt the growth of the plant.
It’s really important to plant the tomato seedlings as deep as possible – this allows them to develop strong roots. I’ll have another chance to transplant them to a larger pot in about 3 weeks, and I’ll plant them even deeper at that time.
