Here's a dwarf maple I've been growing in the ground for 5 or 6 years from a 1 gallon nursery container. It was as thick as a CAT5 or thinner than a pencil.

Just dug up and chopped this spring. I was chicken to cut back more. But later I removed a little more.


Here it is this morning. Placed a branch for approach grafting. Expecting to do another as this other whip grows longer and hardens. So much satisfaction from getting a branch. Looks a bit like bar branching where I placed it, but it really isn't and won't cause reverse taper.

The future looks bright!

Ugh. This maple looks like it may have got a disease. A dark area is developing above the graft union. So I'm got something on the way. A product called Phyton 27. Otherwise the maple has real healthy leaves and growth.

Pics to watch it's slow demise or recovery! The antibiotic antifungal is supposed to arrive end of next week.

The tree


The suspicious dark area. White stuff just residue from parafilm or water I think.


Positive signs at this moment
Healing


Healthy new leaves

Looking ok. Nothing unusual with the leaves and new growth. Dark spots are unchanged. Appear dark because of lighting and wet from rain. Excuse my funny wiring

Treated with Phyton27 today. 1.5 tsp/gallon H2O. I did foliar spray and poured some into soil. A proper drench would be more effective at getting more coverage in the soil. Leaves look healthy and still growing.

phyton is excellent stuff. i use Phyton 35 on my big JM to treat pseudomonas syringae and it is doing a great job. my tree has really greened up!

That's good to hear!

@erb.75 What's the difference between the 27 and the 35? How many applications do you do?

 

[erb.75]

The difference (as far as I know) is the 1-5% of picric acid that is added to the phyton 27. Otherewise i've heard it's identical. The addition of picric acid means you can't use it on vegetables or garden plants that you want to eat.

i have been using it every 7-10 days for 2 months now? maybe only 1.5 months? It looks like the disease has mostly retreated, so I will continue until July and reevaluate continuation of the treatment to the tree at that point.

 

[erb.75]

I do a soil drench + foliar spray. Since it's a big maple, I use ~1 gallon of mixed stuff to get both done each application

So this maple has slowed down. It hasn't died, but hasn't declined neither. What has happened is more blackish color spread around the other big cut where a large branch was removed in the spring. So perhaps I have no disease to worry about. Maybe it's just some death of plant tissue, which is better than any disease. Considering what's going on, I probably won't be ground layering it next year. I've got to make certain that it is growing strong for two more seasons. I decided to continue Phyton 27 treatments for another two weeks once weekly. Maybe again in the fall when constant rain usually returns.

It could be the pics but the leaves look kinda big for a dwarf cultivar

Can you take a pic with something for scale with the leaves ?

Sad to see it isnt doing to well hope it gets better!

 

[thumblessprimate1]

I've been growing this for years in the ground, and it's growth habit is definitely that of Kiyohime. The same goes for the spring foliage. Leaves can be reduced. It must be that I removed over 95% of the growth in the spring that that leaves grew large and some of the internodes are very long. Take notice of the green thumbtack. That should help for scale. If not I'll try to take a picture another time.

 

[defra]

Ah missed a pic !

 

[thumblessprimate1]

Maple alive and appears fine despite those strange dark areas on trunk. Not sure if my sprays treated it or there was no disease to begin with.

By the way, a branch from another tree fell and killed a branch and an approach graft. So gotta try grafts again later.

 

[Melospiza]

Are you planning to air-layer the top part off the graft bulge at some point? Would make for a smaller, but more tapered tree.

I would like to air layer as close as possible to the low branches to form a multi trunk maple.

 

[thumblessprimate1]

Was looking at it today. Here's a thought regarding where I might airlayer. This way I won't need to wait for that wound to close. Not saying that this is a front.

@Mellow Mullet here's a present time look at what worried me in the spring. It's
not looking as black, and it looked like the black stopped spreading or showing up. Not sure if it was just benign dying tissue or the disease was resolved with Phyton 35 and got compartmentalized.

I want to ground layer next spring but this is the only thing that worries me. It's probably not a bad idea to wait more.
