Same thing here in Western NY - today's high 41 / tonight going to 28 or colder, depending on elevation.
However , in 7 - 10 days , they say the temperatures will be in the 70's.
The maples are just about to bust out new leaves, well past the bud stage ; it's daffodil weather - a teaser with touch of frost - but it will kill many annuals.
“it’s daffodil weather “
Mine all froze!
I was looking through that web page from sockmonkey’s post last week, and I saw a small greenhouse/cold frame for around 40 bucks that would be just right for the size of my raised beds, and was thinking I might get that for my winter garden and maybe even be able to grow some Rosemary, if I added a 100 watt bulb on the colder days.
We seem to be past the twenty degree nights thank goodness.
