And so are you able to plant peas?

Not if freezing temps and snow will harm. I don'plant veggies..but if peas sprout quickly, I would say no. We usually get a brief day or two in Feb with snow or ice on ground.
I was climbing on this Sunday to trim dieback from the japanese maple. Monday and Yesterdays warm temps finished it off.. Frogs been at it for three days. Maybe it is a certain type of frog tha heralds the "ok" for the peas.

So what works as a sign in Washington State won't work where you are in North Carolina.
I think each gardener or group of gardeners has to work these signs out for themselves.
We are all in slightly different climates and microclimates.

That's true.

And our frogs in the pond are dosed with algae control. I think they get high.

There is a huge amount of research done on the Phenology of different regions.
Each of us can research what has been done in our own state or province.
Google on your state and Phenology and you will get lots of info.

Interesting subject.

When the pecan tree starts to bud in the spring, is when I bring all my plants back outside.

My grandpa told me that there will be no more frost when this occurs. I've been following this rule of thumb since I started growing tender succulents and pachycauls (back in the early 80's), and it has never failed me.

Not sure if this works everywhere, but it has in SE Texas.

It works here too Reine. Wise old pecan trees.

The question brought an old memory to the surface. I had heard to plant corn when the oak leaves are the size of a squirrel's ear. I looked it up and I guess my memory was almost correct.

Good article. I just don't know how big a squirrel's ears might be...never see any around here.

Here in zone 8 my test is if I can walk in my back yard barefoot without my feet freezing.

That sounds very direct: soil temperature.

It's never failed .. when my feet don't hurt walking barefoot then I start digging!

CarolineScott said:When daffodils bloom, plant peas?

I plant peas when I first see green shoots from the daffodils, unless the moon is waning at that time. Then I wait until a few days after the new moon that follows when the daffodils are shooting up.

From there, it's pretty much by the moon for me. Root veggies, bulbs and other underground things (onions, garlic, carrots, potatoes, radishes, sweet potatoes, ginger, turmeric) on the waning moons. Above ground things (lettuce, greens, broccoli and cabbage, tomatoes and peppers, most flowers and herbs) on the waxing moons. Stuff that is direct sown is sown around the first (above ground) or third quarter (bulbs and root veggies). Transplants are just before the full moon, and generally seeds are started indoors, sown in trays and containers approaching the previous moon's first quarter.

Thinking back, the dogwoods blooming and the other signs mentioned usually align with my lunar cycles for the other plants.
