When Can You Plant Tomatoes Outside in NJ

Tomatoes are a delicious and popular addition to any garden, but planting them at the wrong time can result in stunted growth or even failure to thrive. If you're wondering when you can plant tomatoes outside in New Jersey, here's what you need to know.

Climate Considerations

New Jersey falls within USDA Hardiness Zones 6 and 7, which means the climate can be challenging for certain plants. Tomatoes, for example, prefer warm temperatures and lots of sunshine, and can be damaged or even killed off by frost.

The average last frost date in northern New Jersey is around April 20th, while in southern regions it can occur as early as March 31st. Once the last frost has passed, you can start preparing your garden for tomato plants.

Preparing Your Soil

Tomatoes thrive in well-draining soil that is rich in organic matter. Before planting, you should incorporate compost or other organic materials into the soil to ensure the best possible growing conditions for your tomato plants. If your soil is particularly heavy or clay-like, you may need to add sand or perlite to improve drainage.

Choosing the Right Varieties

When selecting tomato varieties for your garden, it's important to choose varieties that are well-suited to the New Jersey climate. Look for varieties that are known to mature quickly and tolerate hot, humid weather. Some recommended varieties for New Jersey include Rutgers, Brandywine, and Mortgage Lifter.

Starting Seeds Indoors

If you want to get a head start on your tomato plants, you can start seeds indoors about 6-8 weeks before the last expected frost. This will give your plants a head start and allow them to establish strong roots before you transplant them outside. When transplanting, make sure to harden off your seedlings first by gradually exposing them to outdoor conditions for a week or two before planting them in the garden.

Planting Outside

When planting your tomatoes outside, make sure to select a sunny, sheltered spot with good air circulation. Plant your tomatoes about 18-24 inches apart, and make sure the soil has warmed to at least 60 degrees Fahrenheit before transplanting to avoid shocking the plants.

Once planted, make sure to water your tomato plants regularly to keep the soil moist but not waterlogged. Depending on the variety, you may need to provide support in the form of stakes or cages to keep your plants upright as they grow. Prune your plants as necessary to promote good airflow and fruit production.

In Conclusion

Planting tomatoes outside in New Jersey can be a rewarding and enjoyable gardening experience, but it's important to consider the climate, soil, and variety before getting started. With a little preparation and care, you can enjoy juicy, delicious tomatoes straight from your own garden all summer long.
