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.

Crimson Pointe Fruit Set.  4.11.15

 Crimson Pointe plum has impressive fruit set this year.  Last year there were none at all.  The year before, about 3 or 4 plums.

I'm not sure what changed.  I did hand pollinate with flowers from Hollywood plum and Shiro.   I left those branches in the tree for insect pollination, too.   Maybe that was it, or temperature / rain difference.

Looks like potential for a great crop.

Bearded Iris Challenges. 4.12.15

I'm convinced I've been going about growing bearded irises all wrong.  It's not for lack or reading or following advice.  But I think the advice has been all wrong.

I have bearded irises in 4 main locations.

Most of the advice that I have seen is:

They need good drainage.
They should not be mulched.
Plant with rhizome on top of soil.
They need full sun.
Don't over fertilize.
Keep weeds out.

In the various locations -

1.  At the Vancouver yard.  I've been moving those to the Battleground place.   Of the onese that remain, they are not mulched, they are in semi-sunny to shady locations, they don't get fertilizer, and there is a lot of grass among them.  Those do ok.  Not great, but no diseases, and they bloom every year.

2.  At Battleground.  Scattered around the place, no care, growing among weeds and grass, sunny to shady.  Mos of those also do OK.  Not great, but no diseases and they have some flowers. 

3.   At Battleground.  In the front perennial borders. I planted those 3 years ago.  I had heavily amended the area with compost.  The weeds were difficult to manage.  The irises did not thrive.  I didn't care much about there.  Finally I gave up and mulched with a thick layer of wood chips.  I figured they would just die off, and I could plant other plants.   Some had a think layer of pine needles, then a thick layer of wood chips.  Those are growing like crazy, big thick stems, strong growth,  no diseases.  They have big fat flower buds.  There are almost no weeds, on account of the mulch.  A few, not many.

4.  At Battleground.  In raised beds.  These are mostly historic varieties.  There are some repeats from the other beds.   They are in raised beds for better drainage.  No mulch.  I pull the weeds manually.  Last year, these had a lot of bacterial rot.  I attributed that to over-rich soil, dug out a lot of the soil and replaced with unamended soil.  This year, bacterial rot is less but still present.  Some died completely.  Some came up from below ground.  They were looking good, but with recent rains have been covered with fungal spot disease.  Many leaves are dying off.  They look bad.  Some look like they might bloom.

So I've given up growing them correctly.  The irises that get neglected, mistreated, and covered in mulch thinking that would kill them so I can grow other plants - they are doing great.  The ones that I coddled, hand weeded, no mulch  - terrible. 

This weekend the local arborist left another truckload of tree chips on the driveway.  These are fir chips, with a lot of needles mixed with chipped branches.   I removed the major weeds that I could, and covered all of the soil in the iris raised beds with about 3 or 4 inches of chips.  If they live, they live.  If they don't, then those beds will have good rich soil for other plants.  I speculate, the diseases are spread by rainfall on wet bare soil that contains fungal spores and bacteria.  With the wood chip mulch, the fungi and bacteria don't get so much chance to grow on the surface, so rain drops won't spread disease.  I don't know if I'm right, but nothing else has worked.

This was prompted by receipt of 2 more varieties from Old House Gardens, ordered last year.  I don't plan to add more.  I had ordered these before I gave up in frustration.  So I planted those - Monsignor and Flutterby.  Covered with wood chip / fir needle bark mulch.  Enough of that.

Plum & Apple Grafts at 3 weeks. 4.11.15

Ember Plum Graft.  4.11.15

Redfield Apple Graft.  4.11.15

The first of the Fedco scion are out o dormancy.  I grafted these 3.21.15.  It's too early to say for certain, that they fully took.  I think they probably have.

The stems can contain enough reserve carbohydrate and moisture,  for some bud expansion.  I'll feel more secure when leaves are fully unfurled.

These are about 3 weeks.  Pretty good. 

I did bring these inside during the evenings, the past few days.  I read warmer temperatures encourage cambium merging and improve the rate of take.  That may also be why they broke dormancy.  The outdoor grafts on the in-ground trees, are expected to be slower.

Apple progress note. 4.9.15

Prairie Fire Crabapple.  4.9.15

 Most of the apples are blooming.  The Prairie Fire Crabapple that I bought as a pollen source for other apples, is in full bloom.  Using the paintbrush to remove pollen from flowers, there is generous pale yellow pollen, plenty for all of the other trees.

Of the little columnar trees, Golden Sentinel has 2 flower clusters and Red Sentinel has about 6.  Not a lot of apples.  I should prevent them from fruiting so they get more growth, but I like getting a taste.  Karmijn is in full bloom.  The Jonagold, grafted last year onto M27 is 3 feet tall and covered with flowers.  I may want to keep that as a single cordon, looks nice.  Honeycrisp on M27 is blooming.  Honeycrisp is too slow growing for such a non-vigorous, mini-dwarfing rootstock.    I have a more vigorous rootstock start for next grafting year.

Of others, the 3-graft on M106 is blooming nicely.  Pristine is first, and most.  Rubinette is 2nd, then Queen Cox.   With the more vigorous rootstock, these have potential for a lot more fruit in later years.

In the Vancouver yard, North Pole has only 3 flower clusters.  Either due to overbearing last year, or over-pruning of spurs on my part, or both.  Liberty is in full bloom.  Liberty is in lavish full bloom, as is Jonagold.  Both are on M27.  Jonagold is about 8 foot tall, Liberty maxed out at 5 foot tall.


Jonagold 1 year after graft, M27.  4.9.15

 I played the honeybee and transferred pollen from Liberty to Jonagold and North Pole.  I used the meager 3 flowers on North Pole as suppliers of pollen for Liberty.  There may be neighborhood apple trees that I don't know about, to provide more.


Golden Sentinel Bloom.  4.9.15

 Of the apple grafts, in early March I top-grafted from a yellow columnar apple, onto the grafts I made last year from North Pole.  Both have started growing.   One in a container, which had only a tiny tuft of roots, is growing nicely.  The plan for these is a columnar tree with red apples on the lower couple of feet, yellow on the next couple of feet, then another type of red.  The trees would be self pollinating and colorful.


Karmijn on M27.  4.9.15

 The graft from Fedco, of Redfield, onto a home grown M27 rootstock, is starting to grow.  I kept these grafts inside for the past few days to see if I could speed them up.

The neighbor apple graft hasn't started to grow yet.  It is at Battleground.  I moved it into the sunroom.

Jonared at one year old does not have flowers yet.  This is described as dwarf, but the rootstock is not listed.  Given the number of grafts I added from Fedco, I expect at most a bowl or two of apples of each type, in a few years.  That's if the grafts take.  Currently they look unchanged, no sprouting but not dried out.
