Soil temperature for Tomato
Hi- yes, soil temperatures are fine for planting tomatoes. The deeper you plant them the cooler the soil will be, inhibiting root growth somewhat until the soil warms further. However, there is research indicating that planting deeply will produce better long-season growth and yields.
Nighttime temps are expected to be >50 degrees F. through next week so it does not look like we will be facing frost risk. But do keep an eye on the local forecasts and be prepared to cover plants overnight if temps dip to the low 30s.
