in current weather you need nothing, no covers, simply a good wood clean cut wrapped with buddy tape and watch the takes. I have never used covers, not even in winter grafting. Use of foil in current temps could mean death sentence to wood, temps there could rise dramatically.
if you grafted to in ground tree you should not cover it at all, you guarantee 100% frying the wood in these 100 degree temps. If its in a pot, move it to shaded area. I have never covered grafts and professionals will tell you the same. If you use buddy tape, covering does nothing as buddy tape seals moisture damn well and you dont need any additional moisture. What pushes the graft is heat that causes sap to flow from rootstock and then the scionwood.
What do you ladies and gentlemen use to cover grafts on an in ground tree?

Resurrecting this topic in order to keep info that is very related in one thread so that posterity can find the answer in one thread instead of having to search through multiple.What is the absolute max temperature that will be beneficial to grafting? Im asking because my area is in the midst of a heat wave 119F, 104F,101F, 98F (in the 90s for the near future). Would grafting in 119F be advisable? 100F? 95F? 90F? 85?What minimum night time temperature is best? Thanks.
I completely agree with wslau. As long as the nightly average lows are above 62F, you shouldn’t have to worry about flowering on the new push. I like to protect newly grafted scions from direct sun if temps are predicted to be above 90F. The first couple weeks are extremely critical and the scion/graft Union has to be protected. Direct sun on the union can cause evaporation even under the buddy tape/parafilm and condensation can cause mold or rot. Simon
Since everyone is getting scions for mangos, how do you all feel about our current SoCal lows for grafting?Looks like we are in the 57-59 degree range during the night. I know most of my seedlings are either swelling or pushing new flushes the last couple weeks so at least i know the juices are flowing.
Was your rootstock active before you grafted the scion?
Quote from: spoons on April 12, 2019, 12:21:56 PMWas your rootstock active before you grafted the scion?Yeah, they were pushing new buds. I grafted on 5 gallon rootstocks sold as corrinete by maddock. Strongest rootstocks I have seen, doesn't need stakes like manila or turpentine.
