One important think to pay attention to is whether the terminal bud has set.
Lon refers to this when he says 'as long as the plant is still active'.

Look at the rootstock or branch into which you are going to bud and see if
is a 'terminal bud' at the end of the branch or rootstock. If there is a
bud, you are lowering your chances of success because the plant is not active.

During the growing season, the terminus has leaf buds unfurling leaves day
day. When the weather gets hot and/or dry, the plant stops growing and sets
up a
'terminal bud'.

When the weather cools and/or rain begins, the terminus starts unfurling
again (Sept and early October).

Here in PNW, we get a few weeks of hot sunny weather usually mid July to end
August. so somewhere around the end of July the terminal bud has set ...
depends a
lot on weather (temp, rainfall), but also on type of rootstock.

Your best success is going to be when leaves are unfurling either before the
terminal bud sets or after the terminus becomes active again.

I just went out and checked my rootstocks: P22, M9 and M26 all have leaves
unfurling at the terminus so I can bud anytime now. My mature trees on M9
have leaves unfurling.

If I bud right now, I must keep the rootstocks/trees well watered if there is
dry spell because you don't want the terminus to set up for at least three
while the bud is callusing.

Another important thing is to remove the plastic ties before winter. All you
is 'callusing' before winter. If you leave ties on over winter, here in PNW,
buds will rot.

I'm too busy right now hiking with llamas, but I'll start budding about
August 8
and will continue if necessary up to late September ... weather is the big
here. If it gets cold and wet in mid September, I will not have as much
as if it is warm and trees are kept watered.

: Hello All,
: I have a question regarding the opportune time to bud graft.
: According to the hardiness zone map of Ontario, I am in zone
: 6a. According to what I have read about bud grafting it
: should be done when the bark slips easily, which is usually
: late July, into August.
: With our very wet spring, and very cool/wet summer that
: followed, will the period of optimum "bark slipping" be
: pushed off due to the cool nights? Should I wait longer or
: go ahead?
: Possibly someone could review how to determine if the bark
: is slipping enough to bud graft for a rookie.
: It may be a dumb question, but I have never bud grafted
: before.
: Thanks in advance.
: Regards,
: Tom

Was the salesman clueless? Productopia has the answers.
