CS. Good question. lol

Last summer in IL, during the months of June and July, temps were between 100-104F.

The humidity was very high. The odd thing was, one would think it'd rain @ 60+% humidity. Not a drop fell from the sky.

With high temps and humidity, the heat index rose to 109/110F.

I left my plants outside, but they needed more water than ever.

Regarding the plants you have, I'd be skeptical leaving Spiders and WJ's in such high heat.

As far as your other plants, how long have they been outside? Toni

I'd move them in if I were you, better to be safe than sorry

Toni, They've all been outside since April.

I moved the spiders and WJ's inside today.
