Beautiful red, orange, yellow, burgundy, and chocolate tomatoes are a delicious staple in most gardens and greenhouses.
Easy Steps on HOW TO GROW TOMATOES:
The first step in how to grow tomatoes is knowing what they need. Tomatoes need well-drained, warm, medium-fertile soils and a sunny location.
There are many, many varieties of tomatoes with regard to plant size, tomato size, shape, and color. These varieties add tremendous versatility for specific growing needs.
Along with adding a nice, perky freshness to any salad, vegetable tray, omelet, or vegetable dish, tomatoes are a powerhouse of nutrition!

1. SOILS:
- Tomatoes need well-drained, medium-rich soil.
- Moist soils but not waterlogged
- Gardens, garden beds, containers, and pots all work well.
- Just make sure to have at least 20+ inches of soil in your pots and containers.
- Use Organic All-Purpose Fertilizer or a Tomato Fertilizer
Soils differ greatly based on where you live, and they need different treatments. You can easily learn how to test your soil with a low-cost soil tester from Amazon.
2. SUNLIGHT:
Tomatoes need full sun but can handle some shade. They require at least 6 hours of sunlight each day for a healthy crop.
3. TEMPERATURE:
You can grow tomatoes outside once the nights get warmer. Remember, tomatoes like heat since they are heat-loving plants.
They do not tolerate cold weather, so plant outside only after all danger of frost has passed. Consider using tomato covers.
Try this type of season extender, Red Tomato Teepees, for tomatoes.

4. PLANTING:
First Steps to get a jump on early planting:
- Start your tomato seeds indoors or in a greenhouse setting.
- Sow your seeds approximately 6 weeks before the last scheduled frosts for your area.
- Do not start your tomato seeds too early as the plants can become leggy which means they are tall, spindly and weakened
- Leggy seedlings do not do as well as healthy stout seedlings.
- To prevent legginess, make sure your grow light is adjusted close to the seeds as they are germinating.
- Adjust grow light so it is about 2 to 3 inches above the seedlings as they are germinating.
- Raise the light as the seedlings grow.
- Make sure to follow the manufacturer’s instruction on grow light or lamp
- The height of the lamp above the seeds and seedlings will depend on the type of bulb you are using.
Planting Instructions:
- Plant tomato seeds in single rows or put 2 seeds in each cell or plug.
- If using plugs or cells, add 2 seeds to each one to help ensure at least one germinates.
- Space the seeds about 2 inches apart in a soilless potting mix, which makes it easy to transplant seedlings later.
- Cover the seeds with 1/4 inch of potting mix and lightly tap it down to secure the seeds.
- The soil temperature should be between 75° and 90° Fahrenheit.
- Put the cells, pots, or plugs under grow lights or in a sunny window facing south.
- Water the mix to keep it damp, but avoid making it soggy.
Always water the soil and not the leaves; it is not advised to water from overhead.
♦Please Note: add your planting dates and information to your Gardening Journal.
5. COLD HARDINESS:
Tomatoes are extremely frost sensitive; make sure to provide adequate protection for cold temperatures. Consider using season extenders such as Wall O’ Waters to protect from frost. Cold-frames and small greenhouse also offer added protection.
If you just need a little protection for your seedlings, look at a small walk in greenhouse shelter.
6. DAYS to GERMINATE: approximately 10 days
Tomato seeds typically germinate in approximately 10 days if the soil is warm enough. They need warm soil to sprout.
Germination will take much longer if the potting mixture or soil is cold. This happened to me; I thought my tomato seeds were just bad as they did not germinate. But, come to find out… it was my soil temperature.
I had the seeds under a grow light, but it was too cold in the room. The grow light did not warm the soil enough. So, keep this in mind.
7. TRANSPLANTING SEEDLINGS:
When the first true leaves develop, it is time to transplant your seedlings into larger pots. Transplant the young tomato seedlings into 4″ pots. This size pot will allow ample root development and room for growth until they are ready to transplant to their permanent location.
I have re-potted from 4″ containers to 8″ containers as the temperatures were too cold to set outside. This was an extra step, but it might be necessary depending on your location.
If planting in pots or containers, use at least a 20″ pot. Tomatoes need room to spread their roots.
Make sure to plan ahead to protect your tomato plants from blossom end rot!
French watering cans are especially useful.
Remember to water the soil and not the tomato leaves to help reduce disease.
COMPANION PLANTING for Tomatoes:
Tomatoes love asparagus, carrots, celery, cucumbers, onions, and spinach, but they do NOT like brassicas like broccoli, cabbages, cauliflower, and Brussels sprouts, plus they do not like potatoes!
8. SPACING:
Tomato plants need room to grow. Proper spacing will depend on the variety. Make sure to give your plants plenty of room to spread.
Set plants approximately 24″ apart if planting in rows. Make sure to have an adequate container size if planting in pots.
9. VARIETIES:
Special Note: TOMATOES are either determinate or indeterminate.
♦Determinate plants have a set growing height. These are usually classified as a bush variety and do not require any staking, but tomato cages might be helpful if your bush tomatoes are heavy with fruit.
♦Indeterminate plants grow tall and need to be staked with a trellis or some other type of support. Indeterminate plants cannot hold the weight of their fruit, which is why they need staking or a trellis.
Some Tomato Plant Varieties that grow well:
Determinate Tomato Plants that do not need staking
Indeterminate Tomato Plants will need staking:

10. DAYS to MATURITY: varies between 52 and 80
You can expect to pick early tomatoes in about 52 days, while larger late tomatoes may take up to 80 days.
Cherry tomatoes usually ripen faster. It’s a good idea to plant different types for early, mid, and late-season harvests.
Gold Nugget Cherry Tomatoes and Oregon Spring are both early bush varieties, so they don’t need staking!
11. HOW to HARVEST:
- Begin picking your tomatoes as soon as they are a nice size and color. Vine-ripened tomatoes are fabulous!

- Tomatoes will keep a week or longer in the crisper drawer in the refrigerator.
