Well, I guess I can't really say what the soil temperature was recently...basically, they were in (black) pots until yesterday. One gallon size...the plants are about 2+ ft tall. I was doing real good at the acclimating thing, but then we had a cold windy spell that lasted a couple of days, so I had to keep them inside again. When the weather changed back again, I could only put them out for short spells as they would wilt quick in the sun...then within the last 3 days I had them outside pretty much all day and 2 nights outside. Daytime temp was about 70 and nighttime about 40. This time of year is not too bad, but in summer here in Yakima, plants that require "full sun"...well, they soon find out the definition of full sun and usually don't do very well. I suspect now that while the weather feels nice, to a plant the sun is still intense for a young plant.
