Grafting Apple and Lilacs. 3.1.14

Grafting supplies, rootstock, and scion wood.

 Today I did some more grafting.

First, I identified a sucker growing from below the graft of a dwarf apple tree.  The tree is a nonpatented Jonagold.  The rootstock is nonlabeled.

I carefully removed soil between the sucker and the original tree.  Then I used pruning shears to cut through the sucker base between the stem and the tree, close to the tree.

This rootstock was the result.  The original stem was about 3 feet.  I pruned it back to about 1 foot before cutting for the whip and tongue graft.

This method is much easier for me now.  It just took practice, a very sharp knife, and learning how to brace myself and cut carefully and mindfully to avoid slips and lacerations.

Whip and Tongue Graft.

 This side looks good.  The other side was not as good.  I've done a number of grafts where only one side matched up, and they worked fine.

I make sure to place the prepared scion in water until I've cut the rootstock.  I also get that wet.  My thought is it will slide together better with water as lubricant, and there won't be dry surfaces that might impede joining together.

There was a 2nd stem, a little branch.  I cut that off.   That wound is also covered to avoid dehydration, until healing begins.

Wrapped with polyethylene tape.  The wrap goes from bottom to top with generous overlap each wrap around.  That way rain water drains outside instead of trailing into the wrapping.

I did not cut the top off this time.  I don't know if lower buds are viable.  That might result in the graft not taking.

 The 2nd to last photo shows the well-rooted rootstock.  The cut is large.  I don't think that will matter.  It should heal over.

I potted the new little tree in potting soil, in a one gallon pot.  I plan to return it home, and keep on the deck with TLC care for the first year.

I also grafted lilacs.  At the battleground place is a large, very old lilac bush with many suckers.  I expect the suckers have viable roots.  Instead of removing them from the mother bush, I grafted with them in place.  If they take, I can dig them out in the fall.

Scion wood was obtained from 2 non-suckering varieties at the Vancouver house.  They are un-named varieties.  If the grafts take, there are some choices about what I do with the result.  I could keep them as single-stem tree-like shrubs.   I could plant deeply, so that the scion will form its own roots, then later cut off the original rootstock.

Completed graft.

I could consider these a multi-year project.  The first year, allow 2 stems to grow from scion.  The 2nd year, graft again, leaving one or two nodes to grow out below the 2nd level of scion.  At that point, it could be a 3-variety shrub.  Repeating a 3rd year, could make for a multi-variety shrub with 6 or more varieties.  Sort of a bouquet tree.  That will be interesting.  The first step is see if the first grafts take.

The lilacs clearly have viable buds low on the scion, so I did cut them back to one node, containing 2 buds.  Then sealed the cut tips with tree-kote.

Fruit Tree Grafting. 2.25.14

I've been watching the Calendar for grafting time.  I think this is grafting season now for apples and pears.  About the same time as I did last year, which was successful.

Today I added a pollinator variety to the little Honeycrisp, another to the one year old Sutton's Beauty, and one to the one year old Esopus Spitzenberg.  The pollinator varieties are old varieties.

I also added 3 varieties of Asian pear to the 2 year old Hosui, and 2 unknown varieties of European pear to the unknown variety of Asian pear.  This is for pollination.  Also I want to keep those varieties, if we move to the Battleground place.  I prefer more varieties, on the trees already there, than adding more trees.  We don't need a tree-full of each cultivar.  Just a branch for a couple bowls of fruit when each ripens.

Graafting Supplies and Scion Wood

Last year I did cleft grafting on existing trees.  I thought I was too uncoordinated to safely do whip & tongue grafting.  This time I did do whip & tongue grafting.  The saddle grafts all took, and some grew surprisingly fast.  But a cleft graft exposes open wound on each side, which dies and needs to be overgrown by new wood.   The whip & tongue graft does not leave exposed edges, so is potentially healthier.  In theory, all exposed scion cambium is matched with rootstock or branchstock cambium.  That's if the cuts are skillfully done.

I found that sharpening the knife between each graft, the wood cut very steadily.  I steadied my hand against my chest and mad the cuts very slowly, slicing along the blade. The biggest  concern with this method is it is hazardous to the fingers of the grafter.  I did get a small thumb laceration.  It only needed a bandaid.

Whip and Tongue Graft on Asian Pear

I used polyethylene wrap and treekote.  Looks nice and they seem like strongly splinted grafts.

Photo is blurred but still better than my sketch.  I found I had overlap of cut edge over bark.  So I carefully exposed cambium by shaving that section of bark.  Then it matched.

They are a little bent.  They came together with the wrapping.  I dipped in water so cut surfaces would not be dry.

Labels state variety name, expected ripening time, and on the back, graft date.

Wrapped snugly with polyethylene, and labeled.

Some references state polyethlene wrapping does not need external sealer.  Other references state sealer is needed.  A key to success is prevention of dessication, so I sealed.  Treekote is easy to apply.  Messy and not easy to get off the fingers.

Altogether today I did 3 grafts on Hosui pear, 3 grafts on unknown Asian pear, and one each on 3 small apple trees.  Then I wanted to do more but I had homework and a doctor's appointment so I quit.

Lessons learned today.
1.  Grafting is not as hard as I thought.  It takes practice.

Sealed with Treekote

2.  A very sharp knife is essential.  I used a grafting knife, and a hunting knife sharpener from Fred Meyer.
3.  Apply bandaid to thumb before starting.
4.  Work slowly, carefully.  Don't try to slice quickly.
5.  The whip and tongue stays together nicely and does not leave exposed surfaces.
6. Prepare labels ahead of time, with variety name, date of graft, and expected ripening time.  Label each graft as it is completed.
7.  Polyethylene tape is easier than wide rubber bands.  It can be cut from freezer bags, although I got mine via Amazon.
8.  The Treekote is easy to apply too.  That was also via Amazon.

Maybe this weekend I'll graft some plums and cherries.  They are considered more difficult.  The grafting season is short, so I might as well do it now instead of waiting to see how the others do.

Kitchen Garden / Winter Gardening / Raised Beds. Progress Report. 2.23.14

Today in the raised beds I planted:

Parisian Market Carrot seeds.  These are in raised bed which I will use for peppers in May or June.  If not ready by then, any in the way will go to the chickens.  These are a short round carrot, sort of like an orange radish.

Moss Curled Parsley seeds.  Same raised bed.  Ditto for the peppers will take priority.

Snow Peas "Norli".  This bed will go for Tomatoes later.  The peas should be fully done by then.  If not, the tomatoes take priority.  Chickens will like pea shoots.

For vermin control, the first two have a dusting blood / hot pepper.  Same for the Snow Peas, which are also covered by chicken wire, and are in a bed that already has a chicken wire fence.  Last year most of the pea seeds just vanished - I don't know what ate them.  So more attention this year.

 This took all of about 30 minutes.  Most of the day goes for homework.

According to the Park's website, Norli... "French mangetout...Won England's...Award of Garden Merit from the Royal Horticulture Society...ultra-sweet and unbelievably tender...Harvest these peas @ 2 inches long...Entirely stringless...arise very, very heavily on vigorous plants 20 inches high... semi-bush habit...resistance to fusarium wilt"

Apparently "mangetout"is French for edible pod pea.  Park's is always super effusive about everything they sell.   I don't know if I've had fusarium wilt.  I don't think so.

Topset Onions Germinated

Radishes and Turnips Germinated

I removed the row cover from the winter vegetable bed.  This bed was planted 1.28.14 so is just under one month after planting.

I originally used polyethylene cover.  That collected rain and collapsed.  I replaced that with permeable row cover.  That collected snow and collapsed.

Meanwhile, there were freezes into the 20s, and a blizzard.

When I removed the row cover, I saw the radish seeds and turnip seeds had germinated.  A few spinach seeds germinated.  Chinese mesclun germinated nicely.  I did not see any cabbage plants.  The topsets from Egyptian Walking Onions were about an inch tall.  Those were unusually small sets I had in the garage.

I didn't weed this time although it could use weeding.  One of the main challenges is vermin, including slugs, voles, rabbits, mice, and others.  So far these seedlings were not eaten.  Although maybe the cabbage seeds germinated and were eaten.

I watered with diluted fish emulsion as a vermin repellent.  Then I applied a dusting of hot pepper / dried blood for the same reason.  Then I added organic slug bait.

The mouse traps were not set off, but mouse traps in the garage had 3 of 4 traps with mice.  So I moved those to the garage.

I went back to a polyethylene row cover.  This time I used wire fencing as a support.  That will prevent pooling of water / collapse.  I should get a larger sheet so I can weigh down the sides with bricks.  Wind might otherwise catch it.  I changed to the polyethylene again because I think it will hold in more heat, and maybe it is more light permeable as well.  It will stay more dry, which is probably good although it might wind up needing some watering.

Bearded Irises. Progress Report. 2.22.14

Selected Irises 2.22.14

Selected Irises 2.22.14

There is a clear difference in the bearded irises.  They have progressed from winter decline into sturdy early growth.  All have made progress.  Some have growth from underground, unexpected.  I thought Flavescens was nearly died out, but there are some new leaves. 

Daffodils are also growing with flower buds showing.  They are there partly as an animal deterrent, and also as the earliest of spring flowers.

I wondered of the Los Angeles rhizome would survive.  It appears to be making more growth now  The Pallida Dalmatica has more growth than I expected.

So far, so good.

I gave them all some organic slug bait.  Slugs start to make damage, this time of year.
