Manured Squash?

So an area of my plot has had some fairly dry and mature manure dug into the soil a couple of weeks ago and I'm now wondering, as its fairly mixed in now, if it's 'safe' to plant into. If so I'm wondering if butternut squash would benefit from such conditions? The seedlings are about 2 inches high, looking healthy and I'm pondering if now's a good day to plant out, or will they need a hardening first?

Appreciate any advice.

Where abouts are you in the country? It will help when giving this sort of advice.

I've planted some squash out already as my last frost is allegedly end of April. BUT we had a frost mid may last year which knocked my spuds back AND they are out but covered with mesh cloches as a form of protection against any late frost.

I always keep a couple back inside as a back up plan, but they were planted a couple of weeks after the ones that are out now.

I would say you are probably safe to plant them out being so close to the coast. I'm about 5 miles as the crow flies. Having said that I'd listen to the weather forecast and cover 'em up at night until mid May just to be safe.
