Hey John!

Something you could do to guarantee an increase in soil temperature could involve the introduction of soil heating cables. We offer this 48 ft cable that will heat about 12 sq ft of space. https://www.planetnatural.com/product/soil-heating-cable/

You could also introduce moisture to the soil and cover it with clear plastic mulch. Sunlight hitting the dark soil will increase relative humidity and overall soil temperature. This method may be a bit more unpredictable, and has the potential to harm the roots due to extremely high soil temperatures in the first 6in of soil.

Happy Planting!
