When to Start Seedlings

The best time to start tomato seedlings indoors in California is 6-8 weeks before the last frost date. This will give your seedlings enough time to grow strong before being transplanted outdoors.

To determine the last frost date in your area, you can use the [USDA Hardiness Zone Map](https://planthardiness.ars.usda.gov/). Once you know your hardiness zone, you can find the average last frost date for your area by using the [National Gardening Association’s Planting Calendar](https://www.gardening.org/calendar/).

Once you know the last frost date, you can start your tomato seedlings indoors 6-8 weeks before that date. For example, if the last frost date in your area is May 15, you would start your tomato seedlings indoors around March 1.

When starting tomato seedlings indoors, it is important to use a sterile potting mix and a well-draining container. You can also use a seedling heat mat to help your seedlings germinate faster.

To start your tomato seedlings, fill your container with potting mix and press it down firmly. Then, sow your tomato seeds about 1 inch apart and cover them with a thin layer of potting mix. Water your seedlings lightly and place them in a warm, sunny location.

Your tomato seedlings will germinate in about 7-10 days. Once they have germinated, you can thin them out so that they are about 2 inches apart. Continue to water your seedlings regularly and provide them with plenty of sunlight.

Once your tomato seedlings have reached about 6 inches tall, you can begin hardening them off. This means gradually exposing them to outdoor conditions for longer periods of time. Start by placing your seedlings outdoors for a few hours each day and gradually increase the amount of time they spend outdoors until they are fully hardened off.

Once your tomato seedlings are hardened off, you can transplant them outdoors about 2 weeks before the last frost date. Choose a sunny location with well-draining soil. Dig a hole for each seedling that is about twice the size of the seedling’s root ball. Gently remove the seedling from its container and place it in the hole. Backfill the hole with soil and water the seedling well.

Your tomato plants will need to be watered regularly, especially during dry periods. You will also need to fertilize them monthly with a balanced fertilizer.

With proper care, your tomato plants will produce a bountiful harvest of delicious tomatoes.

When to Transplant Seedlings Outdoors

The best time to transplant tomato seedlings outdoors in California is 2 weeks after the last frost date. This will give your seedlings enough time to adjust to the outdoor conditions and start producing fruit.

How to Care for Tomato Plants

Tomato plants are relatively easy to care for, but there are a few things you can do to ensure that they produce a bountiful harvest.

Watering tomato plants

Tomatoes need regular watering, especially during the hot summer months. Water your plants deeply once or twice a week, making sure to wet the soil all the way down to the roots. If the top few inches of soil are dry to the touch, it’s time to water your plants.

Fertilizing tomato plants

Tomatoes are heavy feeders and will benefit from regular fertilization. You can use a commercial tomato fertilizer or a balanced fertilizer, such as 10-10-10. Fertilize your plants every two weeks, starting when the plants are about 6 inches tall.

Pruning tomato plants

Pruning tomato plants can help to improve air circulation and reduce the risk of disease. It can also help to focus the plant’s energy on producing fruit.

To prune tomato plants, remove any suckers that grow from the axils of the leaves. Suckers are small branches that grow from the main stem of the plant. They will take away energy from the fruit, so it’s best to remove them.

You can also prune the leaves of tomato plants to improve air circulation. Remove any leaves that are shading the fruit.

When to harvest tomatoes

Tomatoes are ripe when they are red, firm, and have a slight give when you squeeze them. You can also check the color of the seeds inside the tomato. If the seeds are brown, the tomato is ripe.

To harvest tomatoes, gently twist them off the stem. Be careful not to damage the stem, as this can make the plant more susceptible to disease.

How to store tomatoes

Tomatoes are best eaten fresh, but you can also store them for a few days if you need to. To store tomatoes, place them in a single layer in a paper bag. Store the bag in a cool, dry place.

You can also freeze tomatoes. To freeze tomatoes, slice them in half and place them on a baking sheet. Freeze the tomatoes for a few hours, then transfer them to a freezer bag.

What factors should I consider when choosing a planting date for my tomatoes?

When choosing a planting date for your tomatoes, you should consider the following factors:

• The average last frost date in your area. Tomatoes are frost-sensitive plants, so you need to make sure that they have at least 6-8 weeks of frost-free weather before the first frost date.
• The length of your growing season. The length of your growing season will determine how long you have to grow your tomatoes before the first frost date.
• The variety of tomato you are planting. Different varieties of tomatoes have different maturity dates, so you need to choose a variety that will mature before the first frost date.

How do I prepare my soil for planting tomatoes?

To prepare your soil for planting tomatoes, you should:

• Dig a hole that is deep enough to accommodate the roots of your tomato plant. The hole should be about 12 inches deep and 18 inches wide.
• Add a mixture of compost and well-drained soil to the bottom of the hole. The compost will help to improve the drainage of the soil and the well-drained soil will help to prevent the roots of your tomato plant from becoming waterlogged.
• Water the hole thoroughly before planting your tomato plant. This will help to settle the soil around the roots of your tomato plant.

How do I plant tomatoes?

To plant tomatoes, you should:

• Gently remove the tomato plant from its container and place it in the hole that you have prepared. Make sure that the roots of the tomato plant are spread out evenly in the hole.
• Cover the roots of the tomato plant with soil and gently tamp it down. The soil should be level with the top of the tomato plant’s stem.
• Water the tomato plant thoroughly. You should water your tomato plant every day until it is established.

How do I care for my tomato plants?

To care for your tomato plants, you should:

• Water your tomato plants regularly. Tomatoes need about 1 inch of water per week, but you may need to water them more often if the weather is hot and dry.
• Fertilize your tomato plants regularly. Tomatoes need a lot of nutrients to grow, so you should fertilize them every 2-3 weeks.
• Prune your tomato plants regularly. Pruning your tomato plants will help to improve airflow and prevent diseases.

Generally speaking, you can start planting tomatoes in California from February to April. However, if you live in a warm climate, you can start planting tomatoes as early as January. If you live in a cold climate, you may need to wait until May or June to plant tomatoes.

When choosing a variety of tomato to plant, consider the climate in your area and the amount of time you have to grow tomatoes. Determinate tomatoes are bushier and produce fruit all at once, while indeterminate tomatoes are vining and produce fruit over a longer period of time. Determinate tomatoes are a good choice for gardeners who have limited space or who want to harvest all of their tomatoes at once. Indeterminate tomatoes are a good choice for gardeners who have more space and who want to enjoy fresh tomatoes throughout the summer.

Once you have chosen a variety of tomato to plant, you need to prepare your soil. Tomatoes do best in well-drained soil that is rich in organic matter. You can improve the drainage of your soil by adding compost or sand. You can also add organic matter to your soil by incorporating compost or manure.

When planting tomatoes, it is important to space the plants correctly. Determinate tomatoes should be spaced 2 feet apart, while indeterminate tomatoes should be spaced 3 feet apart. You should also plant tomatoes deep enough so that the stem is buried up to the first set of leaves.

After planting tomatoes, you need to water them regularly. Tomatoes need about 1 inch of water per week. You should also fertilize your tomatoes regularly. Tomatoes do best when fertilized with a balanced fertilizer, such as 10-10-10.
