delayed growth on spruce graft

sluiceJune 7, 2014

Here is a time progression of a grafted scion with delayed growth.

The scion was grafted in February 2011, and developed no new foliage in spring 2011 or spring 2012.

I had almost written it off, until an advantageous bud appeared in summer 2012.

Picea pungens 'Nagykoros', June 12, 2012

Here is the bud on August 11, 2012

The next spring, on May 23, 2013, it appeared as if the bud was about to develop into a new shoot.

Here is the bud on June 25, 2013. Something strange is going on.

July 8, 2013

August 17, 2013, it appears as if new buds are developing on top of the existing bud.

Wow incredible, and so well caught for documentation of the phenomenon.

1) A graft need not push, as long as the needles are healthy and retained.
2) A bud can appear the next year from elsewhere than the previous growth points. But not push - again.
3) It then acts as the axis for several buds to push from it.

Fascinating and well worth knowing that this delayed capabilty exists at least in picea. Life finds a way.

Thank you very much for that, Nate. Great chronology.

So how long did the spider protect it (Aug 17, 2013)?

Yes! This is wonderful documentation. I admire your patience, Sluice!
This kind of cronological series of photos is something we all should do much more for both science and fun. Iôm very inspired by this.

Thanks Severnside, TJ, Jari, and Dax!

TJ, I'll have another look, maybe the spider is still around there somewhere ;)

Just noticed these two new buds today on a P. pungens 'RM 258' scion that was grafted in February 2011. Hopefully they will develop into shoots in spring 2015!

Now that would be delayed! So the needles are four years old? You are certainly showing some extremes of dormancy and reanimation.
