We had a few days in the low to mid 90's; might be the sun/heat for a plant not yet acclimated. My bigger concern is....,

1..) Your soil; it looks really heavy.

2.) What are those tiny white spots on it?

P.S., Otherwise, a recent transplant takes a bit to root in and take off. Mine are not looking so hot now either.

Last week my Area became the 90s too.so maybe it was the heat. Yes the soil is heavy.. But my boss tells me to use that soil. I think the white spots are some perlite that came from a potting mix and somehow mixed in with the topsoil

Basil is different from the majority of herbs most of us tend to grow. Herbs such as lavender, oregano, thyme, chamomile, rosemary, sage, and bay among others are very Mediterranean in origin; so hot, dry, SUNNY and some degree of cold is okay. Most of those excel in poor fertile/excellent draining soils that tend toward the alkaline in pH. Basil is a pure tropical with poor tolerance of drought, and should do well in most average mixes..., not sure they need any special soils and can tolerant a more moisture retentive soil (unlike the others).

Thanks. I've actually in fact planted oreganos, rosemaries, thyme, and lavender and a couple of other herbs as well and they are doing fine except for the basil. So I guess you are right on the basil. Guess I'll keep them well watered and moist

I am in nj as well. My basils are looking worse than yours because of the very cold weather before the hot spell last week. I planted them outside way too early. But I am quite sure that they will bounce back. The new leaves will soon take the place of the wilted ones. I also have basils growing indoor in front of the windows. They are huge compared to the ones in the ground. I started the all from seeds at the same time.
