Is it a trap or an opportunity? My cool weather stuff; beets, lettuce, carrots, spinach, peas, radishes, cabbage, cauliflower, broccoli, and spring onions, are in. I'll replace some herbs that died in last year's heat/drought in about a week and a half. Like Lesa said, I can cover those if I need to. I think I'll be OK with those herbs anyway.
I'm holding off a little while on the pepper, tomato, and eggplant. Those require warm soil to grow and the ground just isn't that warm yet. Those are usually a late April-early May planting for me, but I might try some a little earlier, at least a few tomatoes. But those will be purchased plants. The ones I started from seed won't be ready until my traditional time.
The squash and cucumbers are another question mark. They are so easily damaged by frost, do I dare? And I direct seed. Would they even sprout in the cold ground?
Then there is the corn and beans. I usually have trouble getting them to sprout until the ground warms up. Usually they will rot in the ground if I get them in too early. If these showers hold off so I can get the ground ready, I'll probably try. The okra, I'll hold off on until the ground is really warm.
For about everything, I think it is a matter of how warm the ground is getting. I'll try to start some things early, but it will be stuff I can easlily replace or reseed. I really don't expect this stuff to grow much until the ground warms up if I can even get it to survive, but I'm an optimist at heart. Maybe a cautious optimist. The way this year is going, who knows when the ground willl warm up?
