Early Girl Tomato in Zone 9A — Northern California

Early Girl Tomato is a classic for a reason, and in Northern California's Zone 9A, it's a real winner. You'll get that fantastic, tangy tomato flavor early in the season, perfect for fresh salads, sandwiches, and sauces, all while other gardeners are still waiting for their first ripe fruit. Plus, with our long growing season, you'll have plenty of time to enjoy a continuous harvest.

Our Mediterranean climate, with its dry summers and occasional water restrictions, can present some challenges. But by starting Early Girl Tomato indoors and timing your planting right, you can beat the heat and make the most of our 288-day growing season.

Starting your Early Girl Tomato seeds indoors is key in Northern California to get a jump start on the season. Aim to sow your seeds from mid January through early February. This gives you about six weeks to get those seedlings strong before transplanting.

Use seed trays or small pots filled with a good seed-starting mix. Keep the soil consistently moist – bottom watering is a great trick to avoid damping off. Place the trays in a warm spot, ideally around 70-75°F, and provide plenty of light. Since our spring weather can be a bit unpredictable, starting indoors offers protection from any late cold snaps.

Transplant your Early Girl Tomato seedlings outdoors from early March through mid April, once the risk of frost has passed. Before planting, harden them off by gradually exposing them to outdoor conditions for about a week. This helps them adjust to the sun and wind.

When transplanting, space the plants 24-36 inches apart in a sunny spot with well-drained soil. Even though our last frost is usually past, keep an eye on the weather forecast. If a cold snap threatens, be ready to cover your young plants for protection.

Consistent watering is crucial for Early Girl Tomato, especially in our dry Northern California summers. While it's more forgiving than some other varieties, it still needs regular moisture to produce a good crop. During the hot summer months, you'll likely need to water deeply several times a week.

Use the "finger test" – stick your finger into the soil about two inches deep. If it feels dry, it's time to water. Aim for about 1-2 inches of water per week, depending on the weather. Water at the base of the plant to avoid wetting the leaves and encouraging fungal diseases.

Watch out for signs of underwatering, like wilting leaves, or overwatering, such as yellowing leaves. Mulching around your tomato plants with straw or wood chips will help retain moisture in the soil, which is especially important given our tendency towards drought conditions.

Early Girl Tomato is an indeterminate variety, meaning it will keep growing and producing fruit throughout the season. That means it needs support to keep those vines off the ground!

A standard 5-foot tomato cage or sturdy stakes work well. Install the support at planting time to avoid disturbing the roots later on. As the plant grows, gently guide the stems through the cage or tie them to the stake with soft twine.

Pruning your Early Girl Tomato helps direct the plant's energy into fruit production. Focus on removing the suckers that grow in the "armpit" between the main stem and a branch. Removing lower suckers, in particular, encourages earlier ripening.

Prune regularly throughout the season, especially when the plant is young and actively growing. As the end of the season approaches in late fall, you can also prune off the top of the plant to encourage the remaining fruits to ripen before our first frost arrives around early December.

One of the best things about Early Girl Tomato is that you'll be harvesting sooner than most of your gardening friends! Expect your first ripe tomatoes from late April through late June, about 50 days after transplanting.

Look for medium-sized fruits that have turned a deep red color. The fruit should be slightly soft to the touch. Gently twist or cut the tomato from the vine, being careful not to damage the plant.

To encourage continuous production, harvest regularly as the fruits ripen. If a frost threatens in late fall, you can pick any remaining green tomatoes and ripen them indoors.

Here are some common problems you might encounter with Early Girl Tomato in Northern California:

Blossom End Rot

• What it looks like: A sunken, dark brown or black leathery patch on the bottom of the tomato.
• What causes it: Inconsistent watering, leading to calcium deficiency. Our dry summers followed by occasional heavy rains can create this problem.
• How to fix/prevent it: Water consistently, especially during dry spells. Mulch heavily to maintain even soil moisture. Remove affected fruit.

Early Blight

• What it looks like: Brown spots with concentric rings on lower leaves, spreading upward. Leaves yellow and drop.
• What causes it: A fungal disease that thrives in warm, humid conditions. Soil splash spreads it.
• How to fix/prevent it: Remove and destroy affected leaves. Mulch to prevent soil splash. Water at the base. Copper fungicide can slow the spread.

Hornworms

• What it looks like: Large sections of leaves stripped overnight. Big green caterpillars with white stripes.
• What causes it: Larvae of hawk moths. They can defoliate plants quickly.
• How to fix/prevent it: Handpick them (they're easy to spot once you know what to look for). Bt spray is effective.

Cracking

• What it looks like: Splits in the tomato skin, either around the stem or radiating from it.
• What causes it: Heavy watering or rain after a dry spell. The fruit absorbs water too quickly.
• How to fix/prevent it: Water consistently. Mulch to maintain even moisture. Harvest promptly when ripe.

Northern California Specific Challenges: Our moderate-to-hot summers and low humidity can stress tomato plants. Consistent watering is essential to prevent blossom end rot and cracking. Mulching helps retain moisture and regulate soil temperature. Be vigilant about pest control, as hornworms can quickly decimate a plant in our long growing season.

Companion planting can really boost your tomato game here in Northern California.
