Choosing the Best Tomatoes to Grow Outside: Varieties for Every Gardener
The first step to successful outdoor tomato growing is selecting the right varieties. Not all tomatoes are created equal when it comes to thriving in the great outdoors. Understanding the different types will help you make the best choices for your climate and gardening style.
Determinate vs. Indeterminate: What’s the Difference?
This is a crucial distinction when considering how to tomatoes to grow outside. It largely dictates their growth habit and how much space and support they’ll need.
- Determinate Tomatoes: These are often called “bush” tomatoes. They grow to a certain height (usually 3-4 feet), produce their fruit all at once, and then stop growing. They’re excellent for smaller spaces, container gardening, or if you want a concentrated harvest for canning or sauce making. They generally require less staking.
- Indeterminate Tomatoes: These are “vining” tomatoes that continue to grow, flower, and produce fruit throughout the entire growing season until frost kills them. They can reach 6-10 feet or more and require substantial support (stakes, cages, or trellises). If you want a continuous supply of fresh tomatoes for salads and sandwiches, these are your go-to.
Top Outdoor Tomato Varieties for Flavor and Yield
Here are some of my personal favorites and highly recommended tomatoes to grow outside that consistently perform well for most gardeners:
- ‘Celebrity’ (Determinate): A fantastic all-rounder. It’s disease-resistant, produces medium-large, flavorful slicing tomatoes, and handles outdoor conditions beautifully. A true workhorse!
- ‘Early Girl’ (Indeterminate): As the name suggests, this one ripens early, giving you a head start on your tomato harvest. Produces medium-sized, classic red tomatoes perfect for slicing.
- ‘Better Bush’ (Determinate): A compact determinate variety that produces large, tasty tomatoes. Ideal if you want big flavor but have limited space.
- ‘Sungold’ (Indeterminate Cherry): If you love cherry tomatoes, ‘Sungold’ is a must-grow. These golden-orange gems are incredibly sweet and prolific. You’ll be snacking on them straight from the vine.
- ‘Roma’ (Determinate Paste): Excellent for sauces, pastes, and canning. ‘Roma’ tomatoes have thick walls and less juice, making them perfect for cooking.
- ‘Brandywine’ (Indeterminate Heirloom): For those seeking incredible flavor, ‘Brandywine’ is legendary. These large, often pinkish, beefsteak tomatoes have a rich, complex taste. They can be a bit more challenging but are absolutely worth the effort.
Considering Your Climate and Space
When selecting varieties, think about your local climate. If you have a shorter growing season, look for varieties marked “early” or “short season.” If you have a long, hot summer, most varieties will thrive.
Also, consider your available space. Determinate varieties are perfect for containers or raised beds where space is limited. Indeterminate varieties will need more room and robust support structures.
Getting Started: Your Outdoor Tomato Planting Guide
Once you’ve chosen your champions, it’s time to prepare for planting. A solid foundation is key to a successful season, and this tomatoes to grow outside guide will help you lay it.
Site Selection and Soil Preparation
Tomatoes are sun worshipers! They need at least 6-8 hours of direct sunlight per day to produce abundant fruit. Choose a spot in your garden that gets plenty of light throughout the day.
Soil is incredibly important. Tomatoes thrive in rich, well-draining soil with a pH between 6.0 and 6.8. Before planting, amend your soil generously with organic matter like compost or well-rotted manure. This improves drainage, aeration, and provides essential nutrients.
A good soil test can tell you exactly what your soil needs. Don’t skip this step – healthy soil equals healthy plants!
Starting Seeds Indoors or Buying Transplants
You have two main options for getting your tomato plants started:
- Starting Seeds Indoors: This is a great way to access a wider variety of tomatoes and save money. Start seeds 6-8 weeks before your last anticipated frost date. Use sterile seed-starting mix and provide plenty of light (grow lights are ideal). Gradually “harden off” your seedlings by exposing them to outdoor conditions for increasing periods over 7-10 days before planting.
- Buying Transplants: If you’re short on time or just starting out, buying healthy young plants from a local nursery is a great option. Look for sturdy plants with dark green leaves, no yellowing, and no signs of pests or disease. Avoid plants that are already flowering or have fruit, as they can be stressed by transplanting.
Planting Day Best Practices
Wait until all danger of frost has passed and night temperatures consistently stay above 50°F (10°C). This is a vital part of how to tomatoes to grow outside successfully.
- Dig Deep: Tomatoes are unique because they can grow roots from their stems. Dig a hole deep enough to bury about two-thirds of the plant. This encourages a stronger root system.
- Remove Lower Leaves: Pinch off any leaves that will be below the soil line.
- Add Amendments (Optional but Recommended): A handful of bone meal or a slow-release organic tomato fertilizer in the bottom of the hole can give your plants a great start.
- Plant and Water: Place the plant in the hole, backfill with soil, and gently firm around the base. Water thoroughly immediately after planting.
- Provide Support Early: Install stakes, cages, or trellises at planting time. This prevents root damage later when the plants are larger.
- Space Appropriately: Give your plants enough room to breathe. Determinate varieties typically need 2-3 feet between plants, while indeterminate varieties need 3-4 feet.
Essential Care for Thriving Tomatoes Outside: Tips for Success
Once your plants are in the ground, consistent care is key. These tomatoes to grow outside tips will help you nurture your plants to their full potential.
Watering Wisely
Consistent watering is crucial for tomatoes. Irregular watering can lead to problems like blossom end rot and fruit cracking.
- Deep and Consistent: Aim for deep watering 2-3 times a week, rather than shallow daily sprinkles. This encourages roots to grow deeper.
- Morning is Best: Water in the morning so the foliage has time to dry before nightfall, which helps prevent fungal diseases.
- Check the Soil: Stick your finger into the soil. If it feels dry an inch or two down, it’s time to water.
- Mulch: Apply a 2-4 inch layer of organic mulch (straw, shredded leaves, wood chips) around your plants. This helps retain soil moisture, suppress weeds, and keep soil temperatures even.
Fertilizing for Fruitfulness
Tomatoes are heavy feeders. They need a balanced diet to produce abundant fruit. Start with good soil, but be prepared to supplement.
- Initial Feed: As mentioned, a slow-release organic fertilizer at planting time is beneficial.
- Regular Feeding: Once flowers appear and fruit begins to set, switch to a fertilizer higher in phosphorus and potassium (the middle and last numbers in the N-P-K ratio) to encourage fruiting. Fish emulsion, kelp meal, or a dedicated organic tomato fertilizer are great choices.
- Follow Instructions: Always follow the dosage instructions on your chosen fertilizer to avoid over-feeding.
Staking, Pruning, and Support
Providing proper support is one of the most important tomatoes to grow outside best practices, especially for indeterminate varieties.
- Staking: Use sturdy wooden or metal stakes. Tie the main stem loosely to the stake every 12-18 inches with soft ties or old strips of cloth.
- Caging: Large, heavy-duty tomato cages are excellent. Avoid flimsy, small cages; they won’t hold up to a productive indeterminate plant.
- Trellising: For serious growers, trellising systems offer great support and make harvesting easier.
- Pruning (Optional): For indeterminate varieties, pruning can improve air circulation and direct energy into fruit production. Pinch off “suckers” (small shoots that grow in the crotch between the main stem and a leaf branch). Determinate varieties generally don’t require much pruning.
Pest and Disease Prevention: A Proactive Approach
A little vigilance goes a long way in preventing major issues. This is a crucial part of your tomatoes to grow outside care guide.
- Regular Inspections: Check your plants daily for any signs of pests (holes in leaves, sticky residue, visible insects) or diseases (spots, yellowing, wilting).
- Good Air Circulation: Proper spacing and pruning (if applicable) help reduce humidity around plants, which can prevent fungal diseases.
- Cleanliness: Remove any diseased leaves or fallen fruit promptly. Keep your garden free of weeds that can harbor pests.
- Crop Rotation: Don’t plant tomatoes in the same spot year after year. Rotate crops to prevent soil-borne diseases from building up.
Benefits of Growing Tomatoes Outside: More Than Just Food
Beyond the sheer delight of eating them, there are numerous benefits of tomatoes to grow outside that make the effort incredibly rewarding.
Flavor, Freshness, and Food Security
Let’s be honest, the taste of a homegrown tomato is simply incomparable. They are often picked at peak ripeness, full of natural sugars and complex flavors that are lost in commercial varieties bred for shipping and shelf life.
Growing your own also provides a sense of food security. Knowing where your food comes from and having a fresh, healthy supply at your fingertips is incredibly empowering.
Environmental Advantages: Sustainable and Eco-Friendly Practices
When you grow your own, you control the inputs. You can choose to grow organically, avoiding synthetic pesticides and fertilizers. This is a big step towards cultivating sustainable tomatoes to grow outside.
Reducing food miles (the distance food travels from farm to plate) is another significant environmental benefit. Your tomatoes travel mere steps from your garden to your table, minimizing carbon emissions associated with transportation and packaging.
Troubleshooting Common Problems with Tomatoes to Grow Outside
Even experienced gardeners encounter issues. Don’t get discouraged! Understanding common problems with tomatoes to grow outside will help you address them quickly.
Blossom End Rot
This appears as a dark, sunken, leathery spot on the bottom (blossom end) of the fruit. It’s not a disease, but a calcium deficiency in the fruit, usually caused by inconsistent watering, which prevents the plant from absorbing available calcium.
- Solution: Ensure consistent, deep watering. Mulch helps maintain soil moisture. Avoid drastic fluctuations between wet and dry soil. A calcium spray can offer a temporary fix, but addressing watering is key.
Cracking and Splitting
Tomato fruits can crack or split, often after a dry spell followed by heavy rain. The plant takes up a lot of water quickly, causing the fruit to expand faster than its skin can stretch.
- Solution: Again, consistent watering is your best defense. Mulch also helps stabilize soil moisture. Some varieties are more resistant to cracking than others.
Pests: Aphids, Hornworms, and More
Pests are a part of gardening, but they don’t have to ruin your harvest.
-
Aphids: Small, soft-bodied insects that cluster on new growth.
- Solution: Spray with a strong stream of water, use insecticidal soap, or encourage beneficial insects like ladybugs.
-
Tomato Hornworms: Large, green caterpillars that can defoliate a plant quickly.
- Solution: Hand-pick them off and drop them into a bucket of soapy water. Look for their tell-tale droppings.
-
Spider Mites: Tiny pests that cause stippling on leaves and fine webbing.
- Solution: Increase humidity, spray with water, or use insecticidal soap.
Fungal Diseases: Blight and Powdery Mildew
Fungal diseases are often spread by splashing water and thrive in humid conditions.
-
Early Blight: Dark, concentric rings on lower leaves, often with a yellow halo.
- Solution: Remove affected leaves, ensure good air circulation, and water at the base of the plant. Fungicides can be used preventatively.
-
Late Blight: More aggressive, causes large, dark, water-soaked spots on leaves and stems.
- Solution: Highly contagious. Remove and destroy infected plants immediately. Plant resistant varieties if late blight is common in your area.
-
Powdery Mildew: White, powdery patches on leaves.
- Solution: Improve air circulation, spray with a baking soda solution (1 tsp baking soda to 1 quart water with a few drops of dish soap), or neem oil.
