The foliage of my asparagus plants shows no sign of yellowing yet and isn't
dying back ...

... it usually goes yellow and dies long before now (October typically) ....
I've never seen it like this before.

Question is ...

Should I cut it back ?

or

Leave it growing as is until frosts finally get it ?


Leave it to die down naturally, or be killed by the frost.
Mine's going yellow, it won't be long now.
