I have been growing chayotes for several years here in Los Angeles.
This year I had one day in which the temperature got down to 27
degrees Fahrenheit overnight. Both of my vines look dead. Are they
likely to grow back from the roots or will I need to replace them?

If I do need to replace the vines, is there a variety or a growing
technique that would let the vine produce for a longer period of
time? Thank you in advance for all replies.

his toes. It's just the hard, dead part that grows back but
still. And I do it just because he sticks them in me or
scratches the furniture or me.
