I can describe some general tips for protecting tender plants from cold temperatures.

Depending on how large they are, you can attempt to cover them with lightweight fabric (a light sheet) or clear plastic film. Unless you are going to arrange a frame over the plants, I would stick to the lightweight fabric. I use Agribon in my garden for a little protection.

Thirty-three degrees isn't terribly cold (it's still above freezing), and a lot of tender plants can tolerate a short cold period as long as it doesn't linger long enough to freeze. Covering the plant will insulate slightly and keep it ~1 to 3 degrees warmer during a brief temperature dip.

I think you can leave them in the ground, especially if warmer weather is just on the other side. Nurse them through any short cold spells, and they will enjoy the remaining good weather.
ralleia Reviewed by ralleia on . Outdoor plants and freezing temps Is there any way I can keep my plants out a little longer without killing them when it freezes? The weather says that by friday its supposed hit a low of 33 for 2 days in a row then get warmer again. Im scared that it will get below that and have something bad happen. They were started out door, brought indoor bu then got too damn big so I took them back out and put them in the ground back in August and they are freaking THRIVING but they are not even close to done yet.
