Tomato

Typically thought of as Italian, tomatoes were not originally from Italy. Tomatoes came to Europe from South America in the 16th centuryA member of the nightshade family, this fruit lends itself to both sweet and savory dishes.

Tomatoes come in indeterminant and determinant varieties. Determinate are typically bush and will produce all at once. Indeterminate are typically long vines that will produce continually (Indeterminate grows INTO summer, that is how I remember which is which.)

Growing Tips

Container Friendly

ONLY for tomatoes that grow to a MAXIMUM height of 3 feet, use a 5 gal container. Usually, this is a determinate or bush variety.

When to Start

Spring: Start indoors 6-8 weeks before the last frost.  (End of February/Beginning of March for GA.)

Spring Transplant: After all danger of frost has passed. (May 1 for Jefferson GA.)

Fall: Start indoors. Count back the number of days to harvest from the last average frost date. Then add to that an additional 6-8 weeks for the seedlings to grow. (Start indoors May through the beginning of June for GA)

Fall Transplant:  UGA states the fall transplant dates for tomatoes are June 15-July 15 for GA.

 

How to Start

 

Seeds normally take six to eight weeks of growing and must be hardened off before they are transplanted into the garden. Fill seed cells or pots with pre-moistened seed starter mix.

They will germinate faster with a heat mat. They can be started in small flats and then potted up into containers with adequate drainage holes once seedlings have become sturdy enough. (Seedlings that have at least 2-3 true leaves.)

Sow 2-4 seeds per cell and cover lightly with seed starting mix. Place under grow lights. Thin the seedlings to one plant per pot and pot up as needed.

 

Care

 

Transplant outdoors after danger of frost has passed and soil temps are above 55°F. Plant in full sun and protect from wind. Space plants 3 feet apart. All tomatoes will need a stake or cage for support and they will need help climbing the cage. Gently lift branches and let them rest on the cage.

Tomatoes are picky about temperatures. They require an average temperature of 65-85 F to ripen. If temperatures get higher they won’t set on and would benefit from some afternoon shade.

In some parts of the country (GA and other southern states), there is a fungus that lives in the soil that tomatoes are susceptible to getting. Prune the lowest leaves and keep branches off the ground, as this will help reduce the risk of fungus.

Tomatoes require a lot of water. Even watering will help prevent tomatoes from splitting. Bottom watering is also a MUST. Any soil that splashes onto the leaves is a fungus ready to grow and destroy the plant. Wet leaves are also susceptible to fungus and blight. Use soaker hoses or drip irrigation.

Mulch is also beneficial in suppressing weeds and helping to retain soil moisture. To help prevent birds from pecking your tomatoes, pick them when they show any color change and place them on a countertop to finish ripening. For more planting tips and hacks, see “12 Tomato Planting Hacks.” The link is below.

 

Harvest

 

Tomatoes can be harvested any time they are a mature size. They can be green or fully red or whatever their ripe color is. Tomatoes will continue to ripen off the vine.

 

Pest Management

Tomatoes have several pests that are a real nuisance and destructive to the plants. Aphids, tomato hornworms, root-knot nematodes, and the Eastern leaf-footed bug are some. Companion planting and trap cropping are hugely beneficial in greatly reducing these pests. Marigolds will help with most of these pests and sunflowers will take care of the rest.

Marigolds and sunflowers are, in this author’s opinion, some must-have flowers when planting tomatoes.

Pro Tip!

Incompatibles: Corn, dill, fennel, kohlrabi, and potatoes

Grows well with: Brassicas (kale, broccoli, etc.), carrot, celery, chives, cucumbers, melon, onions, peas, peppers, marigolds and nasturtiums. 

My personal experience

My favorite thing to do growing up was squishing out the juice of tomatoes for canning. I grow my own tomatoes just so I can make homemade tomato juice. I won’t go into great detail about my first time growing tomatoes went back when I knew nothing. (I had to replant 3 times that year!)

 

I’ve since learned a great deal and my 12 tomato planting hacks go into this in great detail. I will plant sunflowers at the ends of my rows and alternate tomatoes with marigolds. 

 

No matter what steps you take, you will always have to look for ‘worm sign’ and pick off the tomato hornworms. My favorite varieites to grow are roma, better boy, and the porterhouse. I use these mainly in canning to make the juice taste like it did growing up. Every year I also try various other kinds, mostly unusual varieites.

Seed Saving

Isolation Distance

 

Almost all modern tomatoes can be safely grown without isolation and will not cross—’currant’ tomatoes (such as Cherry Tomatoes), and ‘potato leafed’ tomatoes (such as Brandywine) are possible exceptions and may cross other currant or potato-leaf varieties.

 

Instructions

 

Grow as many standard tomatoes as desired, but grow only one ‘currant’ tomato or one ‘potato-leaf’ tomato at a time to ensure purity (or cage them, or separate varieties by 500 feet). Currant and potato-leaf tomatoes will not usually cross with common tomato varieties.

Allow tomatoes to ripen thoroughly on their vines to at least the eating stage (overripe is better) before harvesting them to collect their seeds. Upon harvesting, tomato seeds are best fermented in order to remove a germination-inhibiting gel that covers the seeds and to kill diseases. In nature, fermentation of fallen ripe fruits removes this gel, and this process is imitated when preparing tomato seeds.

Step 1: Make a label with the variety of the tomato and any traits you noticed. (Resistant to blight, had really good flavor, bigger size, etc.) Squeeze the pulp from the ripe tomato into a bowl, keeping the label with the bowl. If there is not enough liquid, add enough water to help the seeds separate from the pulp.

Step 2: Let it sit in a warm spot to ferment for 2-3 days and allow mold to form. (Yes, it stinks and is gross. Put it somewhere where you won’t pass by it very often.) TIP: use a tall canning jar. This will help control some of the odor and allow you to see the progress of the seeds. Cover the top of the jar with a cheesecloth or a paper towel, securing with a rubber band, to keep any insects out and yet allow some airflow.

Step 3: Once the layer of mold has formed, lift it off with a fork. This will make rinsing easier. Add some water and mix or shake the jar. The viable, good seeds will sink to the bottom and the bad seeds, which won’t germinate, will float. Skim off the bad seeds and toss. Pour the rest of the seed/pulp mixture through a strainer and rinse. Remove any remaining bits of mold and pulp to leave only clean seeds.

Step 4: Dry your tomato seeds on a piece of glass or a shiny plate—the wet seeds will stick to paper and be difficult to remove without damaging them. Keep the label with the seeds. (All tomato seeds look the same.) Shake the seeds daily to make sure they dry evenly. Don’t speed up the drying process or you could damage or kill the seeds. Once they are thoroughly dry, store dried seeds in labeled, paper seed bags. Drying could take a week or more.

Salsa Recipe

There is a lot of flexibility with this recipe. You can turn this into a roasted version, spicy, smooth, or chunky. There are many other combinations, but here are three that are good to try.

Makes about 1 ½ pints

  • 5-6  Ripe tomatoes, peeled (2 large and rest small)
  • ½ Onion
  • 2-3 Peppers (any combo of bell/banana/sweet/hot that adds up to 1 med bell and 1 banana)
  • 2 Cloves garlic (¼ t if using garlic powder)
  • Handful of fresh cilantro
  • ½ handful fresh parsley
  • Salt to taste
  • Juice of ½ to 1 lime (1-3 t if using concentrate)

Instructions

This is always better on the second day as the flavors have time to develop.

To peel tomatoes, bring a large pot, filled ½ full of water, to a boil. Wash tomatoes and cut off any bad spots. Cut the tops off and place them in boiling water for 30 seconds. Remove tomatoes from the pot and place them in an ice bath or on a plate to cool.

While tomatoes are cooling, dice onion, peppers, and garlic and place in a food processor. Tear cilantro and parsley and add the rest of the ingredients to the mixture. Once the tomatoes are cool enough to handle, remove the skins. Cut into large chunks.

Using a food processor or hand blender, puree all ingredients together. Taste to see if the balance is right and adjust anything to taste.

To make it chunky

Dice the tomatoes, onion and peppers. For firmer tomatoes, don’t blanch, just skin the tomatoes and dice the flesh. Finely chop the herbs and garlic. Add the rest of the ingredients. Mix.

To Roast Peppers for a roasted version

  1. Preheat your oven’s broiler. Cut peppers in half and remove ribs and seeds.
  2. Arrange the peppers on a baking sheet skin side up and place the baking sheet on the highest rack in your oven.
  3. Keep a watchful eye on the peppers. When dark splotches begin to appear on the peppers, remove them from the oven and place them in a large bowl. Cover the bowl with plastic wrap, making sure that it is sealed air-tight all the way around. The steam from the trapped hot peppers will loosen the skins.
  4. Once the peppers are cool enough to handle (probably about 15 to 20 minutes), hold one end of the pepper down on a flat surface and gently peel the skin off of each pepper. The skin should slide off fairly easily.
