Plum Grafts. Progress Report for T-buds and Whip and Tongue Grafts. 4.18.15

The plum whip and tongue grafts that I did last month are looking good.   Buds are swelling for most of the grafts.

Of the Fedco grafts, Ember on Hollywood rootstock is almost leafing out.  Ember top-worked onto unknown plum, buds are swelling nicely.  Both Hanska top-worked onto unknown plum are greening and swelling.  One LaCrescent is doing so, the other one does not look dehydrated, so still has a chance.

Of bud grafts from last summer, they were worth the wait.  Most are growing nicely.  Hollywood top-worked onto  several other trees, is growing.  One of the Prunus cerasifera buds bloomed and set fruit.   The other is growing leaves and stem.  I think I'll leave the fruit there, curious to see how they turn out.  I want only one branch of P. cerasifera, so if the fruiting bud-graft does not grow further, that's fine.  Shiro top-worked onto various trees is also growing on all, with some vigor.

I read several references recommending bud grafting for plums.  Clearly  bud grafting works for plums, but it looks like whip and tongue can also be successful.  There is still some growing to be done before I know for certain.  The advantage of whip and tongue is that budstock can be obtained as I did, in late winter/early Spring, and it does not take the long wait to see if they take.  That is also true in some cases for June budding, such as the Shiro and P. cerasifera buds that grew several foot after I June grafted them last year.

So far this looks like this year has great potential for plums and for grafting plums.
