Potting up Tomatoes (first seedling transplant)
Tomatoes have big long roots and grow very quickly from seed indoors. A few weeks after planting tomato seeds, while it’s still way too cold outside for tomato plants, they need more room. I like to pot mine up into half-gallon milk cartons because they are so deep. Here are some photos and notes of my process:
When seedlings have a couple sets of true leaves, I pot them up into something bigger.
My container of choice is a tall waxed paper half gallon milk carton.
Carefully remove the seedling from it's planting cell and then . . .
Pinch off the seed leaves. This part of the stem ends up under the dirt.
Pot the seedling as deep as possible. Tomatoes will grow new roots along the buried portion of stem.
I probably could have gone even deeper when repotting this tomato seedling.
Firm up the dirt a bit.
Over half the height of the seedling is buried now.
This container will be enough growing room for 3 to 4 more weeks. Hopefully the next transplant will be to the garden.
Any questions? I’d love to get your comments.
