Determinate tomatoes grow only so high, stop and set all the fruit at once, excellent when canning. Indeterminate tomatoes just keep growing and growing and the fruit also keeps coming. Some varieties are semi-determinate and have traits of both.
ThermometerHang one of these kind of indoor-outdoor thermometers on the north side of a post in your garden area. Cut a length of hose a bit longer than the outdoor sensor and wire. Slip the hose over the sensor and wire until the top end of the hose is snug against the bottom of the thermometer. Run the hose down the post, fastening it, and bury the bottom end so that the sensor will be six inches deep.
Digital ones seldom survive the year because of the humidity.

Tomatoes are tropical in origin and need both warmth and light. The winter months will require supplemental lighting. From a practical standpoint it is better to purchase tomatoes at the grocery store during this period rather than trying to grow a crop in a greenhouse. But they are one of the easiest crops to grow during the rest of the year. Here are some tips to assist North Coast growers in enjoying their homegrown tomatoes.

Picking the Right Spot for Your Tomato Plants

Most of the North Coast grows wonderful and flavorful tomatoes, but gardens near the ocean lack the summertime heat. The simplest way to determine the ideal location of your tomato plants in the fog belt is to place them where people go when they sit outside to enjoy the weather. Remember, tomatoes need as much sun as possible.

Tomatoes aren't terribly fussy about the type of soil they're in, and they'll be happy as long as you put the roots below the ground and the leafy part above.

Root temperature is more important than leaf temperature

Many North Coast gardeners hurriedly put their tomatoes in the ground as early as they can in the spring, assuming it will pay off with earlier fruit. But the magic is not associated with them being in the ground versus being in a planter, it's in the soil temperature.  Tomato roots will not grow or provide nutrients to the plant at soil temperatures of 50°F or below. Researchers have found that the ideal root temperature for tomatoes is 70°F.

Techniques to Help You Grow Excellent Tomatoes

bulletUse determinate varieties (explanation) of tomato because they set blossoms and fruit in cooler temperatures.
bulletPut the tomato plants up against a south-facing wall that reflects the light and heat.
bulletBefore planting, put black or red plastic over the soil to "pre-heat" the soil, warm it up faster. 
bulletPlant tomatoes when the soil temperature is above 55°F (how do I find that out?) and the air temperature does not go below 45 degrees at night.
bulletAfter the soil warms up, place dark rocks at the base of the plant to act as mulch and store daytime heat. Putting your tomato plants near concrete walks and driveways works, too.
bulletAbove-ground planters have warmer root temperatures. Use determinate varieties (explanation) if you utilize planters.
