Urgent help needed with strawbs!!

Anyone help??  Pics attached.

   Soil is quite clay. Tiny sprinkling of blood & bone mixed into soil and compost mixed in.

I sympathise I've killed so many strawberry plants its not funny any more.

Some die back of the leaves is normal, how old are they ? If they're this years plants were they hardened off before you planted then. 

Is there any chance they could have been affected by spray drift from weedkiller in the area (could have been any time in the past few weeks if it was glyphosate-based?)

The picture of the whole bed is a bit too small to see much; is there any pattern of damage across the bed or is it completely random?

First picture does suggest the plant is a bit too deep in the soil, although I wouldn't have expected that to cause the sort of die-back you seem to have with yours.

Frost damage?

They've been hardened off, always keep the soil moist, havn't used anything toxic next to them.   I thought maybe it maybe a case of overwatering as it's clay soil so drainage isn't the best so may be being suffocated.  Think the soil's just dodo so might transplant them into pots or different bed.

There's not that much new growth coming through.  I've grew strawbs before and they've never looked this bad.

You've had in the region of 10 different responses and suggestions already, I think we've exhausted all the options.
