Shriveled Winter Melon Seedlings

The picture above shows Winter Melon seedlings that I started in early February. I started 8 seeds and all germinated.

Unfortunately, the weather is too cold for them. Four of the seedlings have already died.

The ones in the picture germinated last.

I bring the seedlings inside at night, but they need warmer weather.

I started another set of seeds today, in case these die as well.
