We're looking at a Saturday night temperature of 32, and not much better Sunday night. Pinch me, is this Texas?
Fortunately we've only got our cool weather crops in the ground, thanks to the soggy spring weather and consequent inability to till, but the plants we've got hardening off are coming back in. Our Old Blush rose is in bloom--think I'll throw a blanket over her!

I'll have to cover my maters and some of the peppers I planted last weekend, when it was 75!
This Saturday, we aren't going to get above 50? Grrr!

We've been going through this for the last few years. Being hit with late cold snap. I buy tomatoes and peppers early to be sure to get some good one. I cover them when it gets cold, you can do it many ways, milk jugs, sheet or buy covers.
I bought some white frost covers and left them on for about 3 weeks last year and the plants grew almost like they were in a green house.

Yep that's the way to do it. You can get cheap frost proofing from Johnny's Seed. Get the kind that are 80% light transmitting. If you are careful, you can re-use it for a few years so it's worth the expense. Not only does it protect them from the frost but they don't get beat up by the wind. Put a cage around them, wrap in frost proofing that's tall enough to be closed overnight and then stop worrying. I use big safety pins to hold on the wrap so I can easily open to fertilize and water.

And while you're looking at Johnny's seed, check out the harvesting tools. I love their hooked knives to harvest lettuce, broccoli and such. Their seeds are nice too. I use them regularly.
