Episode Details

For the best tomato growing season ever, we have tips. Just a few tips.

Today’s newsletter podcast features excerpts from two episodes of the Garden Basics podcast, Episode 93 with America’s Favorite Retired College Horticulture Professor, Debbie Flower, and Episode 259 with Don Shor, proprietor of Redwood Barn Nursery in Davis, CA. two tomato chats with these scenic bypasses for tomato success.

As the sign posted at Don Shor’s Redwood Barn Nursery proclaims: IT’S TOO EARLY.

Wherever you live, wait until nighttime temperatures are steadily above 50 degrees and the soil temperature where you’ll be planting is approaching 60 degrees. Less stress on the tomato plant means earlier, better growth. Note to tomato growers in the desert southwest: how were the tomatoes this past winter?

If you have never “moved up” your young tomato plants into larger pots, start that habit about a month or three weeks before you put them in the ground. Those tomato plants in their original three or four inch nursery containers (or HEAVEN FORBID! in a six-pack) may already be root bound. By the way, why would you want to plant six Early Girl or Better Boy or Sungold tomatoes, all of which would ripen at the same time? As Don Shor is fond of saying about your tomato garden: “Diversify your portfolio!”

Another tomato choosing task: if those tomato plants have been sitting in the nursery for more than a few weeks, or look like there about to tumble off the shelf, always turn over a tomato plant container at the nursery and make sure the roots aren’t coming out the bottom. Ditto for those tomato plants on your back patio, waiting to be planted. Watch for protruding roots! Root stress can set a tomato plant back. Sure, it will recover after it’s finally been planted in the ground, but it will take awhile. Meanwhile, tomatoes that have been repotted into larger pots can stretch their legs for a few weeks, putting on height and vigor to give you a “ready-to-grow” tomato plant once it is in the ground. Athletes warm up before an event. So should your tomato plants.

Even though the calendar says “April”, your soil is just beginning to wake up from winter. Early April is a great time to go shopping for tomato plants. Late April, and continuing through June, is the time to plant tomatoes into the garden. By the end of this month, the weather will be more conducive to rapid tomato plant growth because of more sun, warmer nights (steadily above 50 degrees) and warmer soil (60 degrees and above). But be prepared for sticker shock when shopping.

Checking out the garden center shelves of tomato plants recently at a big box store, tiny tomato plants in four-inch pots were selling for nearly six dollars; six-packs of tomato plants, which were even smaller, were approaching seven dollars.

“Yes, the prices have definitely gone up,” explains Don Shor, owner of Redwood Barn Nursery in Davis. “And there are a couple of reasons for that, besides the increasing cost of labor. One is the cost of heating greenhouses. You don't get tomato seedlings available in March and early April if you don't have a heated greenhouse. If you do it at home, you've got to start them indoors, move the young seedlings outdoors during the day, and then move them back in during the evening. They're not doing that in big commercial wholesale nurseries. They're using propane or natural gas to heat those greenhouses. Plus, greenhouses aren’t very effective when it's cloudy. And we've had a lot of cloudy days.”

Shor emphasizes a few rules for beginning tomato gardeners: don’t buy too many tomato plants, and “diversify your portfolio”. For the first time gardener, start with perhaps one plant per family member, maybe a total of five t
