Sorta depends on what procedure I'm using. If I'm doing a 3 or 4-flap 'banana' graft or modified bark graft on pecan or walnut(or persimmon) - I wrap first with Parafilm - it's easier for me to hold all the pieces together while wrapping Parafilm with less pressure/torque than you have to exert when stretching that rubber band - then the Parafilm holds things together nicely while you overwrap with the rubber. For slow-callusing grafts like nut trees, I'll overwrap the rubber with masking tape or aluminum foil to prevent UV from breaking it down so quickly - but you gotta come back and remove the foil - and sometimes the masking tape as well, but usually loosens up on its own and the rubber band degrades. If I'm doing a simple whip on apple or pear, I just wrap with parafilm, then overlay the graft union with a couple of layers of masking tape - I don't even use a rubber band on those any more - the pomefruits callus in so rapidly that the tape is usually adequate to hold 'em in place 'til they knit together. If I'm doing a whip & tongue on apple or pear, I'll usually do the rubber band first, 'cause even though I've been doing 'em for years, I still haven't got the hang of making my cuts just right so that all cambium layers match up perfectly without really putting some pressure on 'em with the rubber. Then overwrap the whole thing - union & scion in its entirety - with Parafilm.

Your always look so healthy it makes me ashamed of mine, lol. I really have to get some weeding and leaf picking done. Those labels look great! You are going to be going through that tape fast it looks like, lol. Its kind of fun when something pops up and I go oooooh I wonder what THAT is, lol. Something to be said for labels disappearing in my beds. Makes things interesting, lol. The brugs are the only things I really attempt to keep the names for now.

I *think* all of it will be gone now. If not, I'll post one last time to find a home for the rest. Thanks! Cathy

I don't think bubble wrap is the way to go. An insulated pool cover is used by some and sounds like a better idea to me. But honestly any reasonable insulation won't be too much help without a heat source. Maybe a large mass of water inside combined with a pool cover. Depending on your crop you might be able to build a greenhouse inside your greenhouse. Cover the lower structure/frame with row cover/frost blanket.
