When to Plant Tomato Seeds in Ohio 2018

If you're an Ohio gardener, you've probably already started thinking about your spring gardening plans. One of the most popular vegetables to grow in Ohio is the tomato, which has a long history in the state. However, determining when to plant tomato seeds can be a little tricky, as the weather in Ohio can vary greatly from year to year. In this article, we'll help you figure out the best time to plant tomato seeds in Ohio in 2018.

Consider Your Climate Zone

The first thing you should do when planning your tomato planting is to determine your climate zone in Ohio. According to the USDA, Ohio is divided up into five climate zones: 5a, 5b, 6a, 6b, and 7a. Zone 5a is the coldest zone in Ohio, while Zone 7a is the warmest. The zone you live in will play a big role in when you should start planting tomato seeds.

Know Your Last Frost Date

In addition to knowing your climate zone, it's also important to know your last frost date. This date can vary from year to year, but generally falls between late April and late May in Ohio. Knowing your last frost date will help you determine when to plant your tomato seeds, as you'll want to make sure you're planting them after the last frost has passed.

Start Indoors

To get a head start on your tomato season, you should consider starting your tomato seeds indoors. This will give them a chance to grow and develop before you transplant them outside. You can start your seeds indoors about six to eight weeks before your last frost date. This means you'll want to start planting your tomato seeds indoors in late February or early March in Ohio.

Transplant Outside

Once your tomato plants have grown to a certain size, you'll want to transplant them outside. The timing of this will depend on your climate zone and the weather conditions in your area. Generally speaking, you'll want to transplant your tomato plants outdoors when the soil has warmed up to at least 60 degrees Fahrenheit. For most parts of Ohio, this will be sometime in late May or early June.

Conclusion

Determining when to plant tomato seeds in Ohio can be a little tricky, but by considering your climate zone, knowing your last frost date, and starting your seeds indoors, you can give your tomato plants the best chance of success. Remember to transplant your tomato plants outside only after the soil has warmed up to at least 60 degrees Fahrenheit, and be on the lookout for any late frosts that could damage your plants. With a little planning, you can enjoy a bountiful tomato harvest in Ohio this year!
