Tree Autopsy. 10.19.14

Roots of dead dogwood.  10.19.14

Roots of dead dogwood.  10.19.14
 This year I had 3 dead trees.  Two, a Satsuma plum and a Kousa dogwood, were planted summer 2012, did well in 2013, and died mid summer 2014.  The first summer I watered frequently, the second summer I watered rarely.

The 3rd, a Madrone, died without any growth at all.  From what I read, madrones transplant so poorly and die so quickly after planting, I should not have bothered.

I did an autopsy on the plum and dogwood.  It looks like the roots did not grow beyond the original root ball. 

I don't remember if I planted these without cutting away the surrounding roots.  Now I do.  From the book, The Informed Gardener by Linda Chalker-Scott - paraphrased -

The gardener should disturb the root ball, aggressively.  Nursery-grown trees, especially those bought in containers, often have roots that wind around the pot, creating a "root pot" that new roots can't escape.  Roots cross each other and strangle each other.  The roots don't grow into surrounding soil. 

The result is a tree basically growing in a pot, even though there is no pot and it's in the ground. 

The author washes away all soil with a hose, bare-roots the tree, and prunes all winding roots, then replants entirely in native soil, carefully spreading the roots. 

It looks like these trees were victims of my own poor planting technique.   As far as I can see, the roots never extended beyond were the original root ball had been.

The trees are now replaced with home-started trees.  No issues with recovering from nursery abuse, although there's still the forces of nature, and my own learning process.

Gardening is not about what you have, it's about what you create, and grow, and do.

It's not about what you know, it's about what you learn.

Madrone roots
Here is the madrone, taken out of the container.  I felt disappointed - the roots were so minimal.  The tree had been dug close to the trunk, and shallow  The remainder was added compost / soil.  It did look like there was mycorrhizae growing through the medium.  I mixed the medium with soil and placed that around the planted tree.

It will be pretty surprising if this tree grows.  I'll try to water it enough, but not too much.  I added a stake given how little root mass there is to anchor it.

I will also order some more Plant Success mycorrhizal inoculant to add to the soil and water in when it arrives.

Planting a Redmond American Linden

Rounding out the Lindens a little, bought this Redmond Linden through mail order from Southern Oregon.  Expected bare root, my mistake but not a problem.  Came in 5 gallon container.


It's about 6 foot tall. Not bad. Out of container. Hard tell if there are deep winding roots. On the outside, there are a few. This is the main reason I like bare root trees. Easy to tell if there is a potential girdling root. In containers, it can be disruptive to take out the soil, and a lot of work. So I just cut off the winding roots at bottom edges, and top edge, then sliced down about 6 times in the sides to cut any winding roots, and teased out some of the roots. After trimming the roots. Not much taken off. This should encouraged roots to seek out soil further from the tree. Rather than winding around in circles. Planted, soil. Soil/sod levee surrounding tree. No amendments added. I've learned that lesson. Planted with top of pot soil at soil level. A few inches of compost mulch added. Also learned to put the stake in before planting. Easier. Almost every tree I've bought has had 2 leaders. Pruned off the less effective-looking one. No other pruning. Saved the pruning to see if I can root it. fig style.

Trees, leaves, planning for bees. Plant trees in fall. Ginkgo.

That back yard ginkgo. The leaves are yellow now. Beautiful! I say it over and over, but I'm proud I grew that from a seed!
The big maple at the battleground place. So beautiful. Dropping leaves. They will make lots of great compost.
Found this little leaf linden, "Greenspire' at HD. Marked down from sale price of $39.99 to $8.00. Can't beat that price. With plans to start beehives, linden trees are a great choice. I read that linden pollen makes the best honey. This tree had a great root mass. Not too root bound. I did have to prune a few. There is no central leader. It will need corrective pruning for 2 or 3 years. But at that price, who can complain? I cut off a couple of small rubbing branches, that's all. Wait for bloom, prune after that next Spring.
About 8 feet tall once planted. The ground was very easy to dig now. No more summer dry soil. Not too much work. It will be a great source of pollen for the honey bees.
What does it take to make me happy? Leaves for compost is a good start. It's like a christmas present. Leafmas.

Moving a Small Mulberry Tree

Now it's fall. It's chilly.  It's raining every day. Good time to move some more trees, I think. Better than summer, when I moved other trees. This time it's an Illinois Everbearing Mulberry. I originally planted it March, 2010. So it's had 2 summers to grow. I decided it will be hard to keep the growth controlled. The exposure was north of a privacy fence. The neighbor to the south has a massive uncontrolled apple tree, also competing. At the Battleground place, it will have full sun to the East, South, and West. So maybe more mulberries. They are very tasty. One of the most delicious fruits I grow.
 
"Mulberry Tree Wrap" in an old vinyl tablecloth for travel. No pics digging it up. It's the usual, dig a trench, then try to dig deeply under the tree. It was difficult to dig under the tree. Despite the rain, the ground under the tree was dry and hard.
This is my one chance to inspect the roots. Impressive root system. The roots look thicker than the trunk. They were not very deep. Maybe 18 inches, at the most.
Here we are, planted and mulched with about 3 inches of leaf compost mulch. I did line the hole with chicken wire, to annoy and frustrate the mole.  The mole had a tunnel at exactly this spot, so I think the tree was a sitting duck.

I read on another website that mulberries are a tree "not" to plant, due to the berry production. The main concern is that birds eat the berries. Then the birds defecate, the purple poop stains cars. The berries also stain sidewalks. There are no sidewalks here, and no place to park a car near the tree.  Cars are few and far between.  My plan was to keep the tree small, and cover with bird net. I may still do that. I could have cut it down, and bought a new bare-root tree to plant in Spring. Then I would lose two years of progress. By moving it, I may lose some progress, but not much.

I pruned about 1 to 2 feet of new branch growth.  That will make up for root loss.  I don't think I lost a lot of roots.  Probably less than 20%.  Maybe less than 10%.  That compares to commercially grown trees, which I read lose 85% of their roots when moved.

There is also concern about spread of mulberry trees via seeds in bird poop.  I don't think that's an issue here.

Ginkgo biloba seed preparation

It's pretty easy.
They've been in the baggies for a few days. I imagine that if I wanted to wait longer, I would need to refrigerate or keep them cool outside.
It's easy. The seeds mush out. Knife is optional. I did not wear gloves. For the sensitive, gloves are a good idea. Separate the seed from the pulp. Placed the seeds in a bowl of water. The pulp went into the compost. This was under a kitchen hood that vents outside. Working outside is a good option too. Otherwise loved ones will complain about the odor.
Rinsed under running water. Dried on paper towel. Once dry overnight, I'll keep in the fridge until planting.

Moving a young, volunteer maple tree

This maple grew up in a border, at my house in Vancouver. No room there. I decided to move it to the place in Battleground.

This takes me back to when I was a boy. Often a neighbor or family member would have a volunteer tree, and give it away to someone who needed a shade tree. It's a nice memory.  People should do that now.  It would be neighborly, and promote successful, locally adapted species and varieties.

I guess most trees now are clones, grafted to seed-grown rootstocks. Then grown in field-nurseries.  Then bare-rooted, shipped, and sold, or bare-rooted, shipped, and sold to big box stores or nurseries, to be resold. Nothing wrong with being a clone, but it means the tree is probably shipped from a distance, the variety or species may not be locally adapted.  I've seen tropical species sold here.  They won't survive.  The lack of genetic diversity gives propensity for widespread disease, and loss of mature specimens, years later. I'm guessing that a tree on its own roots is more vigorous, but I don't know that.

I have also read, starting with a small tree, it will adapt quickly and surpass trees that were planted at much larger size.  This tree is now plated about 25 feet from the red maple, we planted a few weeks ago.  So we can have a "competition".  Will the little tree catch up to the big one?  Not a fair competition.  They are not identical varieties.  This little tree may or may not be a "red maple".  Acer rubrum.  The leaves look more like red maple than Norway maple, Acer platanoides.   There is also Acer macrophllum, the indigenous "Big Leaf" maple.  This does not quite look like those, either.  Time will tell.

As with other trees, I chose a generous distance from the tree and sliced vertically, making a circle around the tree.  This is a small tree, about 3 feet tall.  I think it sprouted from seed last year.
Continuing the circle.  One side is a short, retaining, stone wall about one foot high.  That made digging easier.  I did not have to dig on that side.
Then the trench, dug farther from the tree.  There didn't turn out to be much root.  I don't think any roots were cut or broken.  That will make for easier adjustment to its new environment.  This area has been enriched with lots of compost.  Digging was easy.  It's been dry for most of the summer.
I placed the tree into a plant container for transport.  I was not able to plant it last night.  So I watered it thoroughly.  Holes in the bottom prevented water-logging.  No wilting at all.   Looks as good as it did before digging.
Now in the ground.  I've been reading, it's better to plant trees at slightly above ground level.  That makes for better drainage.    It may be an issue for compacted soils.  This hole drained very quickly so it is not compacted.  I usually plant bought trees at approximately ground level, as close as I can determine.  It can be difficult to judge.  It's not rocket science.   This tree was "happy" choosing it's own level, so that's were I replanted it.
Filled in, watered, mulched with compost.  Now we await fall.

Planting Plum Trees

The new plum trees came 2 days ago. The varieties are Hollywood (a more columnar shape, purple leaf, nice blooming, purple plum, partially self fertile) and Shiro (wider branching, green leaf, juicy yellow plum, partially self fertile). According to everything that I read, both should do well in this zone and region.

Other than the grape pruning, this then is the first major garden activity to inaugurate the year 2009! I am stoked!

I think that they do a great job packaging the trees. Only two tiny branches were damaged, and they were very minor branches.

Nice roots, nice branches. I've been ordering from Raintree for several years, and their products, plant quality, and packaging have not disappointed me yet.


Soak the new trees for a couple of hours. Since it may still be cold and frost, I soaked to get the trees well hydrated.

Generous holes, with the trees planted so that the grafts were 2-3 inches above the soil line. I did add a LITTLE compost, but not enough to create the 'flowerpot' effect in the clay soil. One tree is in a raised bed with retaining wall, replacing a magnolia that I moved out last fall. This soil was amended several years ago, and the soil level is about 2 feet above the original grade. This area is well drained. The other tree went into less ideal ground, but I heeded the warnings not to over-amend the soil, just adding a little compost mixed in for 'luck'.

Watering them in. After tamping the ground firmly with my feet (but not my ENTIRE body weight, please?), I poured on a bucket of water. Once it soaked in, both were given a layer of well aged yard compost as mulch.

Now planted, ready for Spring. How cool is that?
