Hi,

Germinated four o clock, nasturtium, and be Susan vine seeds to true leaves. Moved out to harden them off. Leaves are turning yellow on all of them. Planted in peat pots in fresh potting soil. Seemed fine until temp went into 40s off and on a few days.

Thanks, Myra in Zone 8, Texas

Regardless of temps its the sunrays that harms them left out in the sun to long.
To hardened them you have to make it gradually then shade them then a while in the sun and so on for a few days before you can have them out all day.

Give the plants an hour per day at first and an extra hour per day each day. And water them more often; wind drys them out faster than being inside. Misting helps until the leaves adjust.

Thanks for input. They were hardened properly and not left out all day until after a week or so. The wind here has been awful. Brought them inside, watered them and will see what happens.
