Grafting Projects in Home Orchard. 2.19.17

New Pear Grafts.  2.19.17

Healed plum whip and tongue graft at one year, done in 2015

It seems seems early, but with buds already swelling, I wanted to get some grafting in.  I think I've done it this early in the past, mid to late February.  Most of the scions are refrigerated in plastic bags, and will keep for several more months if needed.  It's OK if the understock tree is already growing, and for some, that is an advantage.

My grafting goals this year:

• Preserve a few varieties from my old trees in Vancouver, so I have them in my new trees in Battleground.

• Make something more useful out some of the scrubby Hawthorn trees, by converting them into Chinese Haw trees.  This is an experiment.

• Add pollen sources to grow internally on some trees.  I've noticed that the tiny pollinating insects tend to go from flower to flower within a tree.  By having pollen sources in the same tree, maybe there will be better fruit set.

 • As usual, I want to add some novel varieties.  Those will be added as I receive scion, especially the apples from Fedco and possibly some from Home Orchard Society.

•  Seedling fruits may start to bear sooner if grafted onto a mature, bearing fruit tree.  That gives a chance to evaluate the seedling variety several years sooner than letting it mature on its own roots.

• By creating multigraft trees, I have more varieties in less space than I would if they were all on their own rootstocks.  You get pollenizing  varieties for better fruit set, and potentially widely spaced ripening times so that instead of bushels of one apple type all at once, you can pick various types from July to November.

• Taking scion from your own trees, they are free.  Buying scion is usually much, much cheaper than buying trees.  Scion from scion exchanges is also free.

Healed apple whip and tongue graft at 6 months, done in 2014.

Grafts so far.  All of them are whip and tongue.

1.  This week, I grafted pear varieties, I think Anjou and Bartlett, from the old multigraft.  Whatever they are, they are good pears, delicious, proven in this area.  I added both to both of the new pears in my Battleground yard, Rescue and Orcas.

2.  I have a tiny Honeycrisp apple on M27, which is way to dwarfing for that variety.  After maybe 10 years it is still only 2 feet tall and gets one or two apples a year.  I took scion from that "tree" and grafted onto a more vigorous Winecrisp apple tree, one year old on a more vigorous semidwarf rootstock.

3.  I grafted two variegated burgundy on green plum seedlings, from plums that I bought in 2015, onto 2 of the younger plum trees - Toka (onto a rootstock sucker) and Ember.  I grafted one onto the Sweet Treat Pluerry.  I also grafted an American plum seedling onto Ember plum, to see if that would pollenize that tree.   I also grafted some variegated plum seedling onto a higher branch on Methley plum tree.

4.  I grafted several Chinese Haw scions onto suckers or younger trees in the Douglas Hawthorn woodlot.  I hope they take and make those into something productive, and maybe also not grow so top heavy and fall over like the original trees have been doing.  Both are in the Hawthorn genus, Crataegus, so I imagine they will take.

5.  To the Maxie hybrid Asian-American pear, I added Hamese and Hosui.  Last year I added Rescue and unknown Asian Pear from the Battleground yard.   I may convert that Rescue branch into something else, such as Shinseiki or Nijiseiki.  I don't need a bushel of one variety of Asian pear to ripen all at once, and it's nice to have multiple types ripening at potentially different times.

5.  Pending:  3 apple varieties from Fedco, and if I am luck some persimmons from Home Orchard Society.  I have more apple varieties now than I need, so for the most part I'm not planning to add more.  If I'm up to it, I  might make more use of some of the Hawthorne seedlings / suckers as experiments.  Hawthorn appears to be closely-enough related to pears that some pears can be grafted onto some hawthorn rootstock.  Some do better than others.
