How To Grow Tomatoes From Seeds

Tomatoes are a great plant to grow in your garden as they grow well in most warmer climates. Though you can buy mature plants to plant right into your garden or a container, you can also grow them straight from seeds.

Though growing tomatoes from seeds can seem intimidating if you have never done it before, it is quite straightforward with the right knowledge. Growing from seeds also gives you more variety in the type of tomato you grow.

Decide On Your Seeds – How To Grow Tomatoes From Seeds

Before you get planting, you want to decide on your seeds. Some varieties of tomatoes are more ideal for certain recipes than others are.

Also, be sure you have the right room for the variety you want to grow. Determinate tomatoes grow to around three feet tall, making them the best choice for containers. On the other hand, indeterminate tomatoes grow to be very large, up to six feet tall, making them a better choice for garden beds.

Plant Your Seeds In Small Containers

Once you have selected your type of tomato, you will want to plant it indoors in small containers. You can use yogurt cups or egg cartons, as long as they have holes for drainage poked in them.

Use a seed-starting mix as soil to encourage root growth. Fill your containers up with the mix and use a spray bottle to water the soil until it is moist.

Plant your seeds around 1/8-inch deep in your soil, placing two to three seeds per container. Gently firm over the seeds with soil to ensure sufficient contact with the soil. You can then cover the containers loosely with plastic wrap to keep the moisture in.

As your tomatoes continue to grow, you can begin to introduce them to the outdoors. Place them outside for a few hours and bring them inside whenever temperatures fall below 50 degrees Farenheit. Repeat this process for around 10-14 degrees Fahrenheit.

Around two weeks after the last frost or when soil temperatures are at least 60 degrees Fahrenheit, you can transplant your tomatoes into your garden. Plant them in an area where they will get at least six to eight hours of sun a day. Allow around two to three of space between tomato plants to give them plenty of room.

Tomato Care

Before planting your tomatoes, mix compost into the soil. The soil should be loose and well-draining. Around five weeks after transplanting your tomato plants, add mulch to help the soil retain moisture.

Use organic fertilizer or tomato fertilizer every two weeks to ensure your tomatoes are getting enough nutrients. Avoid using fast-release fertilizers and avoid high-nitrogen fertilizers on your tomatoes.

Water your tomato plants in the morning so they have plenty of moisture throughout the day when it gets hot. Water generously the first few days after transplanting your tomatoes. Your tomato plants will need around two inches of water a week.

Taller varieties can benefit from stakes or cages. This will help prevent fruit from developing on the ground and help the plant stay upright.
