Transplanting Heirloom Tomatoes

Once my heirloom tomato plants start to grow their second set of true leaves, I transplant them from the small seed starting cells to larger pots.

The transplant mixture that I use in the new pots is a combination of my standard seed starting mix and perlite. I usually mix about 4 parts seed starting mix to 1 part perlite. After the mixture is combined I wet it with water before placing it in the pots.

Transplant Mix

I place a little transplant mixture in the bottom of each pot. Note: make sure that whatever pot you use, there is a drainage hole in the bottom. I usually use a pot that is between 3 inches and 4 inches in diameter at the top. I have used a wide variety of pots over the years, from yogurt cups to standard green plastic pots. Recently I have been using a natural, biodegradable, and OMRI listed pot, they work really well.

Once I remove the transplant from the seed starting cell I cut off the bottom leaves from the transplant. When I place the transplant in the new pot I make sure to bury the stem deeper then it previously was, to help encourage the development of a stronger root system. I only let the top leaves and a little of the stem stick above the mixture in the pot.

Note: make sure to move the plant labels with the transplant so you don’t forget what was planted in the pot. I place the completed transplants back into the seed starting tray and place them under the grow lights. In a few weeks they should be ready to harden off outside.

  1. Good tip about burying the stem deeper than it previously was to develop stronger root systems. Many gardeners, especially newer ones, aren’t aware of this.
