Tomato Planting Guide

Tomato Planting Guide

Tomatoes can be found in nearly every vegetable garden across the country, and with good reason, as little else compares to the flavor of a home-grown tomato. There is a multitude of varieties, filling out the entire spectrum of color, size, and flavor.

How To Grow Tomatoes

Start: Start tomatoes indoors 6-8 weeks before last frost. Use a quality seed starting mix and grow under grow lights or in a very sunny, warm window. Plant seeds ¼” deep and keep soil moist. Harden off seedlings in a sheltered outdoor place for one week. Transplant after danger of frost. Seedlings should be planted 30-48” apart in rows 3-4’ apart.

Transplant: Plant outdoors when nighttime lows reach 60°F or higher.

Water: Tomatoes require plenty of water, 1-2” per week. Ensure watering is steady as tomatoes can crack and split if they receive a lot of water after a dry stretch.

Light: Full sun.

Soil: Plant in rich organic soil. pH 6.0-6.8

Fertilize: An all-purpose, balanced fertilizer will do well for tomatoes. Use according to the manufacturer’s recommendations. If you find your tomatoes have very lush, green vegetation but are not setting fruit, switch to a fertilizer with little or no nitrogen.

Harvest: Harvest tomatoes when they are as ripe as possible, fully colored and firm. Make sure to pick regularly to avoid overloading the plant. At the end of the season when a frost is imminent, all remaining tomatoes can be picked and ripened in a paper bag or on a sunny window sill.

Notes: Place stakes or cages at the time of planting to avoid damaging the plants’ roots.

  • If you notice a hole in the upper left-hand corner of your Farmers' Almanac, don't return it to the store! That hole isn't a defect; it's a part of history. Starting with the first edition of the Farmers' Almanac in 1818, readers used to nail holes into the corners to hang it up in their homes, barns, and outhouses (to provide both reading material and toilet paper). In 1919, the Almanac's publishers began pre-drilling holes in the corners to make it even easier for readers to keep all of that invaluable information (and paper) handy.
