When to Plant Tomatoes Outside in Boise, Idaho

Tomatoes are delicious and versatile fruits that add flavor to various dishes. They are popularly grown in home gardens and serve as a staple ingredient in many American households. For Boise, Idaho residents who want to grow their tomatoes, it’s vital to know the best time to plant them outside.

The Best Time to Plant Tomatoes Outside in Boise, Idaho

The best time to plant tomatoes outside in Boise, Idaho is between late April and early June. This time frame is ideal because tomatoes need warm temperatures to germinate and grow successfully, and this period provides enough warmth for them to thrive. Furthermore, planting during this time ensures that tomato plants can mature before the onset of fall and before the first heavy frost which usually occurs in October.

The Importance of Soil Temperature

Soil temperature is a critical factor in the successful growth of a tomato plant. Tomatoes grow best when planted in soil that is 60 ℉ or above. If the soil temperature is too cold, which can happen in early spring, it can lead to slow growth and sometimes even death of the plant. Therefore, it's essential to test the soil temperature using a thermometer before planting tomatoes outdoors. A soil thermometer can be easily purchased at a garden supply store.

Starting Tomatoes Indoors

In case you miss the planting window for tomatoes outside, starting them indoors is another option. This lets you plant tomatoes earlier, and you can transplant them to your garden once the temperatures warm up. If you wish to start your tomatoes indoors, you'll need to plant them in containers with drainage holes for easy drainage of excess water.

Start by filling the container with potting soil, plant the tomato seeds, and place the container in a sunny window with temperatures ranging between 70-90 degrees Fahrenheit. Make sure to maintain the soil moisture to ensure optimal growth of the seedlings. Once the seedlings reach six to eight inches tall, it's time to transplant them outside when temperatures warm up.

Conclusion

In conclusion, planting tomatoes outside in Boise, Idaho requires adequate knowledge of the best planting time, soil temperature, and starting options. Late April to early June is the ideal planting window, and the soil temperature should be at least 60 ℉. Starting tomatoes indoors is another option if you miss the outdoor planting window. With these tips, you can successfully grow tomatoes in Boise and enjoy fresh, juicy tomatoes all season long.
