It’s time to plant tomato seeds.

Craig LeHoullier and Lisa Hilgenberg shared their knowledge with a group of garden bloggers.
I am more excited than ever to plant tomato seeds after spending some time last Saturday with Craig LeHoullier, author of Epic Tomatoes and Lisa Hilgenberg, horticulturist at Chicago Botanic Garden. They shared their experiences growing tomatoes with a room full of eager garden bloggers. Then, I attended his lecture at the Chicago Botanic Garden along with a room filled to capacity with tomato-loving gardeners.

Craig LeHoullier named the Cherokee Purple tomato in 1990. He co-hosts an annual tomato tasting event called Tomatopalooza in Raleigh, North Carolina. He is deeply involved in the Dwarf Tomato Breeding Project. He grows LOTS of tomatoes in containers in his driveway. Craig is passionate about tomatoes!

His enthusiasm is infectious. He shared his tips to planting and growing tomatoes in containers.

Count back eight weeks from the last frost date to determine when to plant seeds.
This slide showed the timing of planting tomato seeds.

Timing is everything. Count back eight weeks from the last frost date to determine when to plant seeds. After four weeks, transplant seedlings to larger pots. After an additional four weeks, plant them outside.

Don’t skimp on potting mix. Use fresh soilless potting mix every year – don’t re-use last year’s potting mix.

Plant seeds properly. Barely cover seeds with potting mix, and loosely cover pots with plastic wrap. Craig flips his plastic wrap every day.

Tomatoes need light. After seeds germinate, get them under lights as soon as possible. Don’t worry if seedlings get leggy. Stretched seedlings can be planted deeply later.

Harden off plants. Acclimate tomato plants to their new environment gradually before planting outside.

Plant tomatoes properly. Remove leaves toward the bottom of stems and plant them deep. Roots will form along buried stems. Apply a layer of mulch to help retain moisture in the soil and to prevent water from splashing from soil to foliage. Allow enough space between plants – at least three feet apart – for good air circulation, minimizing disease risk.

  1. Whoa. That must have been one very interesting day. Why didn’t someone tell me about this? I certainly would have attended. Dang!

    1. I was invited by the PR folks at CBG. I think it may be an annual event so I will be sure to mention your name next year. You would have loved it!
