Better Boy Tomato in Zone 8B — Northern California

Better Boy Tomato is a fantastic choice for Northern California gardens. The flavor is classic tomato – juicy, slightly sweet, and perfect for everything from fresh salads to homemade sauce. Plus, its disease resistance is a real boon, helping it thrive even with our variable spring weather.

We know our Mediterranean climate here in NorCal can be tricky, with dry summers and the ever-present concern of water restrictions. But with a little planning and attention to watering, you can absolutely enjoy a bountiful harvest of Better Boy Tomatoes. Our long, 269-day growing season gives you plenty of time to succeed.

Starting your Better Boy Tomato seeds indoors is the way to go here in Northern California. Aim to sow your seeds late January through mid February, about six weeks before you plan to transplant them outside. This gets you a jump start on the season, taking advantage of our early spring.

Use seed trays or small pots filled with a good seed-starting mix. Keep them warm – a heat mat helps – and provide plenty of light. A sunny windowsill often isn't enough, so consider using a grow light. Water gently from the bottom by placing the tray in a shallow dish of water; this encourages strong root growth.

Transplanting your Better Boy Tomato seedlings outdoors should happen mid March through mid April. Before you plant them, harden them off by gradually exposing them to outdoor conditions for about a week. Start with an hour or two of shade, increasing the time and sun exposure each day.

Plant your seedlings 24-36 inches apart in well-amended soil. Keep an eye on the weather forecast – we can still get some unexpected chilly nights even then. Be ready to cover your young plants if frost threatens.

Watering is critical for Better Boy Tomatoes, especially with our dry summers here in Northern California. These plants need consistent moisture to produce those big, juicy fruits. Aim for about 1-2 inches of water per week, depending on the weather.

Use the "finger test" to check soil moisture: stick your finger about 2 inches deep into the soil. If it feels dry, it's time to water. Water deeply at the base of the plant to encourage deep root growth. Overhead watering can lead to problems, especially in humid microclimates.

Signs of underwatering include wilting leaves and slow growth. Overwatering can cause yellowing leaves and potentially root rot. A good layer of mulch, like straw or wood chips, will help retain moisture and regulate soil temperature.

Better Boy Tomatoes are indeterminate, meaning they'll keep growing and producing all season long. They need strong support to handle the weight of all those tomatoes. A sturdy cage or staking system is essential.

Install your support at planting time to avoid damaging the roots later. Cages are easy – just place them around the plant. For staking, drive a sturdy stake into the ground a few inches from the plant and gently tie the main stem to the stake as it grows.

Pruning your Better Boy Tomato plants helps improve airflow and fruit size. The standard approach is to remove suckers – the small shoots that grow in the "armpit" between the main stem and branches.

Pinch off these suckers when they're small. Also, remove any yellowing or dead leaves near the bottom of the plant to prevent disease. As the end of the season approaches (late November in NorCal), you can top the plant to encourage the remaining tomatoes to ripen.

You can expect your first Better Boy Tomato harvest late May through mid July, about 72 days after transplanting. The tomatoes are ready to pick when they're a deep red color and slightly soft to the touch.

Gently twist or cut the tomato from the vine, being careful not to damage the plant. Regular harvesting encourages continued production. As the first frost approaches in late November, harvest any remaining green tomatoes and bring them indoors to ripen.

Here are some common problems you might encounter with Better Boy Tomatoes in Northern California:

Blossom End Rot

• What it looks like: A dark, sunken spot on the bottom of the tomato.
• What causes it: Inconsistent watering leads to calcium deficiency. Our dry summers and potential water restrictions can make this a challenge.
• How to fix/prevent it: Water consistently, especially during dry spells. Mulch well. Avoid over-fertilizing with nitrogen. Remove affected fruit.

Cracking

• What it looks like: Splits in the tomato skin, either around the stem or radiating outwards.
• What causes it: Sudden changes in soil moisture, like heavy watering after a dry period. This is common with our Mediterranean climate's boom-and-bust rainfall.
• How to fix/prevent it: Water consistently. Mulch to maintain even moisture. Harvest ripe tomatoes promptly.

Hornworms

• What it looks like: Missing leaves, often overnight. Large green caterpillars with white stripes.
• What causes it: These caterpillars are voracious eaters.
• How to fix/prevent it: Handpick them (they're easy to spot). Use Bt spray. Leave any hornworms with white cocoons on them – they're being parasitized by beneficial wasps.

Early Blight

• What it looks like: Brown spots with concentric rings on lower leaves, spreading upwards.
• What causes it: A fungal disease that thrives in warm, humid conditions.
• How to fix/prevent it: Remove and destroy affected leaves. Mulch well. Water at the base of the plant. Improve air circulation. Copper fungicide can help.

Northern California Specific Challenges: Our moderate-to-hot, dry summers and water restrictions mean consistent watering is crucial. The low humidity helps reduce some disease pressure, but the temperature swings during the growing season can stress plants and make them more susceptible to problems.

Companion planting can really help your Better Boy Tomatoes thrive in Northern California.

Good companions include:

• Basil: Repels tomato hornworms and whiteflies.
• Carrots: Improve soil aeration and deter nematodes.
• Parsley: Attracts beneficial insects.
• French Marigolds: Repel nematodes and other pests.

Avoid these companions:

• Brassicas (cabbage, broccoli, etc.): They compete for nutrients.
• Fennel: Inhibits tomato growth.
• Corn: Attracts tomato fruitworm.
