Okay, seeing how the cold weather just doesn’t want to go away here in the north east…
How cold can you safely put new plants in the ground?
If I don’t start planting soon it will be summer and way to hot!
Temps today are 45 degrees, but this weekend supposedly…supposedly it will be in the mid 60’s.
But by next week it is going back to the 50’s…
Will it be fine as long as it doesn’t go below freezing?

This is a perfect time to plant considering how much rain we have had and how moist the soil is. Most Perennial flowers for your area will be more than ok to plant . If your doing veggies yes you may have to keep an eye out for frost still. I don’t plant tomatoes or other warmer weather veggies till after May the 15. But once again now is a GREAT time to plant.
This thread should be moved to the GARDENING section of this forum…please move it.
Around here, we don’t plant veggies until the snow is off the top of Mt Spokane. Of course, that won’t help you much… 
Perennials… generally ok when the ground is no longer frozen. Annuals after the last frost, check the local almanac, or the local nursery.
It’s frost and or hard freeze that you need be concerned with for tender plants. Around here Mother’s Day is usually safe. In Warwick you should be similar if not a bit sooner.
Should you plant too early, you can always cover tender plants with newspaper the evening before a frost and remove once the sun is up and frost gone. They can generally handle the cold, but not the frost.
Fred, the thread is here now. Might as well deal with it 
Find out when your average last frost is. Usually you are fine to plant by then. Looking on a map it ranges from April 1 to the 30 depending what end of the sate you are in. The hardy plants will be fine even if you plant beofre the last frost. Just dont plant before your last freeze. In most cases by mid April you are good.
I’m usually in a state of disrepair…
BTW here in New Mexico we just had two nights of “Hard Freeze”. We’re at 5400 Ft elv. so this is not that uncommon. Average last frost is May 15th. I really hope that we froze all the dang mulberries. The tree is the primary cover for the RR, and thousands of the gooey things make a real mess.
When the snow is off Terrace Mountain or May 25th long weekend, whichever comes first.
It depends on what your planting. A general guideline to start preparing when the Forsythia bloom. In Eastern Mass May 15th is usually safe for most things- Tomatoes & eggplant 10 days later. The safe dates are trending earlier with climate change. Soil temperature is an important consideration, as quite a few things will tolerate being transplanted too early, but will not really grow. It also depends on the “heaviness” of your soil ( ratios of sand-loam-clay ) These determine drainage ie:moisture content, and soil temperature ) Your County Extension Service should be able to assist you on typical planting dates for specific cultivars in your general area.
