The little garden Vegs

As most of you who follow me know I live in the  high dessert at an elevation of 3,200 feet and  have 60 a day growing season.
We have already dropped to 32 degrees at night and I am covering the plants every night with plastic.
When checking out what grows well here I was told you just can't grow these plants here.

The bare spot is where spinach has already been harvested.
