When Can You Plant Tomatoes in NJ?

Tomatoes are a popular crop for home gardeners in New Jersey, but knowing when to plant them can be tricky. The ideal planting time depends on several factors, including the climate, soil temperature, and variety of tomato you plan to grow. Here is a breakdown of the best time to plant tomatoes in NJ:

Early Spring Planting

If you want to get a head start on the growing season, you can plant tomatoes in early spring. The best time to do this is when the soil has warmed up to at least 55 degrees Fahrenheit, which typically occurs in late April or early May. You can use a soil thermometer to check the temperature of the soil. Early spring planting is ideal for indeterminate varieties, which will continue to grow and produce fruit throughout the summer and fall.

Mid-Spring Planting

If you miss the early spring planting window, you can still plant tomatoes in mid-spring. This is generally considered the ideal planting time for determinate varieties, which produce fruit all at once and then stop growing. Mid-spring planting typically takes place in late May or early June, when the soil has warmed up to around 60 degrees Fahrenheit.

Summer Planting

You can also plant tomatoes in the summer, although it is not recommended. The hot and humid New Jersey summers can put stress on tomato plants, which can lead to disease and poor fruit production. If you must plant tomatoes in the summer, choose heat-tolerant varieties and plant them in an area with afternoon shade. Make sure to keep the soil moist and provide ample airflow to prevent disease.

Fall Planting

If you missed the spring and summer planting windows or want to extend your growing season, you can plant tomatoes in the fall. The best time to do this is when the soil has cooled down to around 70 degrees Fahrenheit, which typically occurs in early September. Fall planting is ideal for determinate varieties, which will produce fruit before the first frost. Make sure to protect your plants from cold temperatures with covers or blankets.

In conclusion, the best time to plant tomatoes in NJ depends on several factors, including the climate, soil temperature, and tomato variety. The ideal planting time ranges from early spring to mid-spring for most varieties, with fall planting recommended for extending the growing season. Make sure to choose the right tomato variety for your planting time and garden conditions, and provide adequate care to ensure a bountiful harvest.
