One of my trees is dropping its leaves due to fungal infection, chemical burn, or a combination of both.

I was wondering if it would be helpful to give it a little nitrogen, thinking that it may need help regrowing all those leaves.

Is this advisable, or is there even something else that would help?

Of course, i could do nothing....

Seems like Serviceberry or Juneberry (Amelanchier species) should have its own thread here.

There are a few random mentions of it on the forum but nothing consolidated.

I just harvested some from a parking lot flowerbed for the second time In a three year span.


I was and am so surprised at how good these berries are. This treeís fruit is really sweet and refreshing, with flavors similar to peach or muscat grape.

For now my burning question is how to propagate this particular plant. I welcome all advice.

But otherwise I hope folks will post useful info of any kind pertaining to this fruit.

Thanks!

Never done this before but Iíve been inspired by recent tour videos here on the forum.
The usual disclaimers apply: Iím not a videographer!
Itís early in the season and my pawpaws are young, so itís not too dramatic.

Here goes nuttin!

Like a good feller I did a forum search for Bacillus amyloliquefaciens and found this old post:
I'm having horrible Phomopsis problems on my Dot mango.  It has almost killed the small tree back to a stump.  I went to Orange County Farm supply and their pesticide guru recommended Monterey Complete Disease Control with an active ingredient of bacillus Amyloliquefaciens.  He says it is a beneficial Bacteria that outcompetes most harmful bacteria and Fungi such as Phomopsis and Powdery Mildew.  Since it is a bacteria you only have to use it as a drench once to get it into your soil.  As a foliar you need to spray it every two weeks.  Has anyone tried this?  It sounds too good to be true.

I was searching my local Co-Op shelves for an anti-fungal to use on trees with Diplocarpon(black spot) and found Bonide Revitalize, which uses this bacterium.

Like the user above, itís sounds too good to be true.

Anyone try this stuff?

I'm trying to wrap my head around the general plant physiology concept that leaf surface drives root growth, and root growth drives leaf surface growth. (or maybe that's not even stated accurately.)

The specific situation I have is young seedling trees or even grafted trees under 3 feet tall - the trees are trying to form lateral branches at this short height, branches which are too low to be viable fruiting branches long-term.

So my thought had been to pinch-off this lateral growth to encourage more vertical (apical bud) growth.

So my question is - if the axiom stated at the outset is true, am I hindering the root establishment of these young trees by reducing the photosynthetic potential?
(The assumption/catch here is that by pushing multiple branches, the tree can increase leaf-surface faster than if it is only pushing from the top bud. This may not be true)

Thoughts from the intelligentsia?

Temperate Fruit Discussion / Emerging pawpaw leaves bright yellow
« on: April 04, 2019, 09:12:41 PM »



This one of my grafted trees leafing out. Hard to tell from the pic but the baby leaves emerging are highlighter-yellow.
Itís been in the ground a full year.
Only tree thatís doing this. Have not fertilized, so itís not burn. This and all trees just starting to push leaves.
Only thing that has happened was a freeze 3-4 nights ago. But in my experience that results in darkened, eventually black leaves.
Young pawpaw leaves can be yellowish until mature but nothing like this ....

Tropical Fruit Discussion / Skanky Coffee Grounds
« on: March 20, 2019, 03:21:05 PM »
I had been collecting used coffee grounds (and filters) from a local coffee shop a couple years ago.

I had some large buckets filled with the grounds just sitting outside, for about 2 years.

I finally went to empty them and one of them was really foul (i.e. sewer-like) from anaerobic fermentation.

So my question is - should I throw that batch out rather than use around trees? Would only apply a thin layer with some other organic matter as a top-dressing, not digging it into soil at all.

I am drying-out the grounds in the sun now.

Temperate Fruit Discussion / Brand-new pawpaw variety introduced
« on: February 20, 2019, 04:36:51 PM »
To those who may not have seen or heard, Neal Peterson has released a new cultivar, his first in several years.

It's only sort-of new..... it was one of his advanced selections from the same work that produced his previous cultivars. But he is only just now naming and releasing it.

"Tallahatchie"

You can read more on PetersonPawpaws.com

I was so caught-up in the buzz that I just ordered one from One Green World. As far as I could see, they are the only place selling them right now. Hurry and get one before they're gone!

Tropical Fruit Discussion / Tree planted too shallow?
« on: January 19, 2019, 12:07:51 PM »
In the spring of 2018 I planted this one year old Asimina triloba seedling.

I guess I was a little sloppy and didnít get it deep enough and/or the potting mix settled a bit.

Either way, some roots are exposed near the base of the trunk.

The tree seems healthy enough - it doubled in size in its first year in the ground.

The roots have mostly lignified by now.

Any reason to do anything about this, and if so, what would it be?

I recently posted this question to OurFigs.com but wanted to tap the brain trust here too....

I recently went to dig-up a dormant Celeste fig that was in the ground for 2 summers (unfortunately I didn't plan well and need to move it).

I found that 4 of the shoots, 1-inch+ in diameter each, had rooted themselves into the mulch and organic matter just clear of the main root crown.

I carefully cut the shoots from the main crown and unearthed as many of their own roots as i could - each had a fairly significant root system of its own. I trimmed the cuttings to about 10 inches or so in total length. (is this too long for the cuttings?)

I chucked them in pots with a peat/bark "nursery" style potting mix and wrapped the exposed shoots in parafilm.

My main question is----what now? Should I bring them indoors to a room-temp environment and or keep them more 40-50 degree temps until spring?

I really don't know what i'm doing  ;D

Tropical Fruit Discussion / Fire in the Hole!!!!!
« on: December 05, 2018, 03:09:16 PM »
I've worked myself into a little paranoia around overwintering fungal spores carried by dead leaves.

A few of my trees were hit hard with Diplocarpon fungus and naturally their leaves fell to the mulched area around the tree base.

Of course i have removed the dead leaves (pretty religiously), but my paranoid mind is thinking they have shed trillions of nasty spores onto the wood mulch, and these will infect the plant next season.

So i had the crazy idea of torching the area with my Weed Dragon flamethrower. It's one of the "homeowner" ones, not super high-powered.

So here are my questions:
1) is my paranoia unfounded? i.e. Is removing the dead leaves good enough?
2) would the quick heat even kill spores anyway?
3) would it damage shallow feeder roots of the tree?

I guess I could remove all the mulch under the tree and replace with clean mulch, but clearly that's a lot of work and more expense (though not totally out of the question).

Temperate Fruit Discussion / Cocktail-grafting Muscadines
« on: November 26, 2018, 03:06:05 PM »
I have a couple of 2-year-old muscadine vines ordered from Ison's. One is Ison, one is Darlene.

I wondered about grafting other varieties onto these vines in cocktail-style, where maybe I aim to change half of each vine to another variety, thereby having 4 varieties instead of 2.

But I know nothing about grafting grapes. I tried googling grafting muscadines but everything i found was talking about propagation of entire plants, not "cocktail" grafting.

Anyone know anything about this or have any cuttings to share?

Tropical Fruit Discussion / Eggs deposited in bark...
« on: November 15, 2018, 08:32:37 PM »


I suspect these are a series of insect eggs, something like a cicada or similar critter (orthopteran).

Anyone have experience with this?

Wondering if these should be carefully removed (or treated some other way) or just left alone - not sure if the larva/nymphs would do any further damage?
Or maybe they will not survive the winter?

Any ideas appreciated

Temperate Fruit Discussion / Grafting Mulberry?
« on: October 24, 2018, 01:12:04 PM »
I think i discovered a wild mulberry sapling on my property. About 2.5 feet tall and pencil-thick.

I know a bit about grafting but nothing specifically about mulberry.

Anyone have experience with this tree? What season should grafting be done, and are there any other "tricks?"

Of course, I would have to find a source for scions. If anyone has any or knows of a source, let me know.

Temperate Fruit Discussion / Leaf Scorch?
« on: September 24, 2018, 04:59:15 PM »
Are the following pictures indicative of ďleaf scorch?Ē
These are young trees that for most of the summer I fear had wet feet causing a weak root system.
I exposed the soil around the trees to aid in drying. We then have had quite hot, dry, and windy weather.

Iím thinking this is the perfect setup for leaf scorch.

Thoughts?

Tropical Fruit Discussion / I Turned My Orchard Into a Swamp - now what?
« on: August 02, 2018, 08:42:57 PM »
Iíve just come to the realization that I have basically been drowning my newly planted trees by surrounding them with excessively deep woodchip mulch. Clay soil is compounding the problem.
The soil around the trees seems rather like mud.

To remedy this, I have cleared away the mulch in a 2 foot diameter around the tree to temporarily expose the soil to speed drying.

What else can I do, if anything?

Would spading around the tree help/hurt?
What about working up the very top layer of soil 1-2 inches to increase surface area for evaporation?

My plan was to eventually add a much thinner layer of mulch back once moisture levels seem more normal.

Temperate Fruit Discussion / Best time to relocate Fig?
« on: July 04, 2018, 03:13:51 PM »
I have a fig in the ground since last April or May.....I want to move it to another spot.

Assuming the best time to do this would be the fall, once it's totally dormant, or perhaps late winter/early spring before it breaks bud.

Thoughts/advice/cautionary tales?  I've never moved a tree before, so any other general advice is appreciated.

Tropical Fruit Discussion / Planting trees grown in Gritty Mix
« on: July 02, 2018, 11:48:03 AM »
I have a couple potted trees that have been grown in Al's Gritty Mix.
I want to plant them in the ground - would there be issues just planting with whatever Mix remains intact around the roots, or should I estentially bare-root the plant?
I was concerned about the radical soil differential by having essentially gravel around the root ball and then native soil around, which has a fair amount of clay.

Temperate Fruit Discussion / Fig not really fruiting?
« on: June 13, 2018, 11:45:58 AM »
I bought and planted a 2-gallon Celeste (supposedly) fig last April. It grew fine, but it dropped the fruits that it formed when they were about marble-sized.
We had a pretty brutal winter and very cold April. I did cover the tree totally in leaves to try to protect it, but there was still some bark cracking due to the cold.

It has put on some new growth from last year's shoots, but mostly it has sent up several new shoots from the base. They're about 3-feet tall now. Tree looks very healthy.

however, there are no fruits forming on the new shoots from the base, and only a few from the new growth originating from last year's wood.

Is this typical?

Maybe the new basal shoots just need a few more weeks to form fruits, or....?

Help from y'all who are experienced would be greatly appreciated.

Temperate Fruit Discussion / 2018 Wild Pawpaw Watch Thread
« on: March 01, 2018, 10:18:02 AM »
Kicking off the 3rd annual "Wild Pawpaw Watch Thread!

Hard to believe this is the third year.

The purpose of this thread is to document the progress and productivity of wild pawpaw (Asimina triloba) patches.
Anyone and everyone who has pawpaws growing in their area is welcome and encouraged to contribute.

I'll go ahead and get us kicked off:
Here in TN, we have had a crazy-warm second half of February. (Also crazy-rainy.) We've actually had a couple of days reach 80 degrees. Have not had any frost in a couple of weeks at least.
Bradford Pears and Chinese Magnolias are blooming as of a couple of days ago. Daffodils, etc are up and blooming.
Sooooooooo.....are the pawpaws blooming yet?

Last Sunday (2/25) I checked the "mother tree" in Nashville that I always keep an eye on. The flower buds were definitely in action but not open yet. The size of small blueberries. The flower "stem" (peduncle I believe is the term) was quite elongated on most flower buds.
This tree has always had early-ripening fruit, so perhaps it's ahead of other trees. I haven't been able to look at my local wild patches yet.

We have some cool nights coming up, forecast around 32F, but I don't see anything that would harm the flowers. Last year we had some 20F nights in March that really zapped things.

Fingers crossed for no late freezes.

Temperate Fruit Discussion / YIKES! Fig damage - what's up?
« on: February 15, 2018, 02:09:57 PM »
I have a Celeste fig that was in about a 1 gallon pot when I planted last April.
I read about covering figs in the winter to prevent dieback, so I basically completely buried it in leaves.

It has reached 72F here today, so I went to remove all the leaves to prevent "overheating" per recommendations from the nursery.

I found on the main trunk some splitting of the bark:



Is this cold damage or freeze/thaw damage? Or "overheating" damage?

What are the consequences of this damage?


Thanks for the help!

Tropical Fruit Discussion / Treating with root stimulant
« on: February 09, 2018, 07:20:56 PM »
Is there any value (or negative effect) to watering newly transplanted seedlings with rooting stimulants/hormones such as DynaGro KLN?
