Better Boy Tomato in Zone 3B — Midwest

Better Boy Tomato is a classic for a reason, and it earns its place in any Midwest garden. The flavor is that perfect balance of sweet and tangy, making it ideal for slicing onto sandwiches, canning into sauce, or just enjoying fresh off the vine. Plus, the reliable yields mean you'll have plenty to share with neighbors.

Our Midwest weather can be a bit unpredictable, but with the right timing and care, you can absolutely grow fantastic Better Boy Tomatoes. We have a fairly short growing season of only about 118 days, but starting indoors and choosing a disease-resistant variety like Better Boy gives you a great head start.

Starting your Better Boy Tomato seeds indoors is essential in our Zone 3B Midwest climate. Aim to start your seeds mid-April through early May, roughly six weeks before you plan to transplant them outside. This timing helps avoid any late frosts we often see around here.

Use seed trays or small pots filled with a good seed-starting mix. Provide consistent warmth (around 70-75°F) and plenty of light, either from a sunny window or, even better, a grow light. A little tip I've learned: water from the bottom to encourage strong root growth and prevent damping-off. This is especially helpful with our sometimes cool and damp springs.

Transplanting your Better Boy Tomatoes outdoors should happen early to late June, once the risk of frost has passed. Before planting, harden off your seedlings by gradually exposing them to outdoor conditions for about a week. This helps them adjust to the sun and wind, preventing transplant shock.

When planting, space your tomato plants 24-36 inches apart in well-drained, fertile soil. Give them plenty of room to grow. Midwest springs can be quite variable, so keep an eye on the forecast and be ready to cover your plants if a late frost threatens.

Better Boy Tomatoes are thirsty plants, so consistent watering is key, especially during our Midwest summer heat spells. But remember, we also get our share of rain, so it's about finding a balance.

A good rule of thumb is to water deeply once or twice a week, providing about 1-2 inches of water each time, depending on rainfall. Stick your finger about 2 inches into the soil – if it feels dry, it's time to water. Focus on watering at the base of the plant to keep the foliage dry, which helps prevent fungal diseases that thrive in our humid summers.

Signs of underwatering include wilting leaves and blossom end rot on the fruit. Overwatering can lead to yellowing leaves and root rot. Mulching around your plants with straw or shredded bark helps retain moisture and regulate soil temperature, which is especially helpful with our clay soil.

Better Boy Tomatoes are indeterminate, meaning they'll keep growing and producing fruit all season long. That means they need strong support to keep those heavy vines and tomatoes off the ground.

Cages or sturdy stakes work best. Install them at planting time to avoid disturbing the roots later. I prefer cages because they provide all-around support and allow the plant to grow naturally. As the plant grows, gently guide the stems through the cage or tie them to the stake with soft twine.

Pruning your Better Boy Tomatoes can help improve airflow and fruit size. Focus on removing the "suckers" that grow in the crotch between the main stem and branches. These suckers will develop into additional stems and can overcrowd the plant.

Prune suckers early in the morning on a dry day to allow the cuts to heal quickly. I usually start pruning a few weeks after transplanting and continue throughout the growing season. As we approach mid-September and the threat of frost looms, you can top the plant to encourage the remaining green tomatoes to ripen.

You can expect your first Better Boy Tomatoes to ripen mid-August through mid-September. These tomatoes take about 72 days to mature. The fruit should be a deep red color and slightly soft to the touch.

Gently twist or snip the tomato from the vine, being careful not to damage the plant. For continuous production, harvest ripe tomatoes regularly. If a frost is predicted, harvest any mature green tomatoes and bring them indoors to ripen. They'll ripen best in a single layer, out of direct sunlight.

Even with the best care, you might encounter some common tomato problems in our Midwest gardens:

Blossom End Rot

• What it looks like: A dark, sunken spot on the bottom of the tomato, often on the first fruits.
• What causes it: Inconsistent watering leads to calcium deficiency. The wet-dry cycles we sometimes experience in the Midwest exacerbate this.
• How to fix/prevent it: Water deeply and consistently, especially during dry spells. Mulch around the plants to maintain even soil moisture. Avoid over-fertilizing with nitrogen.

Cracking

• What it looks like: Splits in the tomato skin, either around the stem or radiating from it.
• What causes it: Sudden heavy watering after a dry period. The fruit swells too quickly.
• How to fix/prevent it: Consistent watering is key. Mulch to keep soil moisture even. Harvest ripe tomatoes promptly.

Hornworms

• What it looks like: Large sections of leaves missing overnight. You might also see large green caterpillars with white stripes and dark droppings.
• What causes it: These are larvae of hawk moths that lay eggs on tomato plants.
• How to fix/prevent it: Handpick the hornworms (they're easy to spot). Bt (Bacillus thuringiensis) spray is effective and safe.

Early Blight

• What it looks like: Brown spots with concentric rings on the lower leaves, spreading upwards. Leaves turn yellow and drop off.
• What causes it: A fungal disease that thrives in warm, humid conditions.
• How to fix/prevent it: Remove and destroy affected leaves. Mulch to prevent soil splash. Water at the base. Improve air circulation by spacing plants and pruning.

Midwest Specific Challenges: Our moderate-to-hot summers and moderate-to-humid humidity can create ideal conditions for fungal diseases like early blight. The wet-summer rainfall can also lead to inconsistent soil moisture, contributing to blossom end rot and cracking. Consistent monitoring and proactive measures are essential for success.

Companion planting can benefit your Better Boy Tomatoes. Basil is a classic companion, improving flavor and deterring pests. Carrots and parsley attract beneficial insects that prey on tomato pests. French marigolds also deter nematodes and other soil pests.

Avoid planting brassicas (like cabbage and broccoli) near tomatoes, as they can stunt tomato growth. Fennel inhibits the growth of many plants, so keep it away. Corn can block sunlight and compete for nutrients, so it's best planted elsewhere in your garden.
