This spring I’m going to be grafting my pear block. I’ve got 250 Pyro 2-33 rootstocks on order and will be benchgrafting 5 trees each of 50 different cultivars–mostly French Heirlooms–in late March.
Is there anyone else out there actively using Pyro 2-33 who can comment on the plusses and minuses you’ve discovered using this rootstock?
It’s described as possessing the following qualities:
*No known incompatibilities with several varieties for over10 years of testing.
*No root suckering.
*Good soil adaptation.
*Moderate-to-tolerant resistance to Fireblight.
*Good winter cold hardiness.
*Good root anchorage w/excellent root system.
*Excellent precocity and yield efficiency.
Also, trees grafted onto Pyro 2-33 are said to start bearing in the 2nd or 3rd leaf and with heavy pear production 2 years earlier than OHxF97. Further, there allegedly is no reduction of fruit size and the trees reach full bearing in 4 -5 years.
Have you found these above claims to be true? I’d love to hear anyone’s experiences using this rootstock. Thanks.
I will bet that you are the only are likely one of few people in the forum to have access to Pyro 2-33. My only question is can you bump your order up and sell me few? I’m sure you can get commits from forum members for 50. I will take at least 6.
Derby, sorry for the delayed response. I got mine from Sierra Gold Nurseries since the Pyro 2-33 I’d originally ordered through Tree Connect this year didn’t grow out as predicted.
@lordkiwi did an order and was nice enough to divide them this spring. A friend will pick them up for me when they arrive. The rootstocks though expensive @ around $4 each should be worth the extra money with expected fruiting in the second year http://www.fowlernurseries.com/Rootstocks.htm. $109.18 with shipping for 25. They have a dwarfing similar to ohxf87 http://treefruit.wsu.edu/web-article/pear-rootstocks/. Typically most rootstocks I pay .50-$1.30 depending on quantity delivered. I’m trying a test block of 25 trees and like several members I’m excited about them and will post updates. They are said to be tolerant of FB and have no known compatability issues after 10 years of testing http://www.treeconnect.com/pdfs/Pyro_%202-33.pdf. I will take pictures start to finish and graft all different scion wood. A friend said the package arrived late today and he began taking care of them for me on arrival.
I had complete failure this spring bench grafting OhxF87 and want to try something different. Does anyone wish to comment on this rootstock? How does it graft and then grow?
Pyro 2-33 rootstocks were much less hardy than ohxf rootstocks in Kansas. Out of all that i ordered not a single one lived. They are not hardy enough to survive here.
