Speaking of thinning, I just found one of my Shenandoah baby fruits has been sawed in half:



It’s a clean cut. I had thinned this cluster to one fruitlet, and it was about pinto bean sized.

What in the world?!?

That's too bad. My guess is that an insect ate the small fruit. Probably the other half will die. I hope that other fruits have formed and the monster does not get an appetite for them as well;-) My Susquehanna from last year is not blooming yet, I hope she will do so next year.

Hi Sergey,

okay,  I only do not know the botanical names o f some wild gropwing trees with their botanical names but I iwll take some photoes of some where I am thinking which can be interesting for you! From Junglans nigra or from my  Junglans regia with thin S´nut shells I have currently nuts from last autumn available.

From our local "German" Oaks I have collected many nuts last year for trying a told method to attract woodworms  wooden things, but this method did not work therefore I threw al oaks away in winter...and I used concentrated vinegar for killing them - and, this worked....

Hi Forester, if you are also interested in common oaks growing in Germany I can take some pictures of oaks which are growing in my surrounding. I also have walnut on my land which produces extremely hard nuts which are also a little bit larger than normal walnuts. I cab take photoes of them end of September.

Flowers are open on one of my trees, buds are on three or four more. Interesting that California is behind Tennessee in bloom time.

Too bad your anticipation was spoiled so quickly, but I know what it's like. They bloom a few times at first before they keep and train the fruit after maybe another two years.

The experience I have made on many trees is that the trunk at the bottom has to be about as thick as a man's thumb before the tree produces fruit for the first time and does not shed it while still small.

I’ll see if there are any flowers left to check on the colors.  The leaves have the pattern of reticulata. 
I named our farm after Odenwald Germany where my Grandfather was born.

That's interesting that your grandfather is not far from the area where I live here. Have you ever been here? By the way, the beautiful city of Heidelberg is right at the foot of the Odenwald!

Now to the Paw Paw of which you wrote: Yes, that would be nice if you could have a look, in case there are no more flowers, there will surely be fruits sometime......maybe you can post some more pictures, and if it would be possible for you to send me some seeds against reimbursement of expenses, that would be great.

I have owned my land for a year now and just discovered that I have dozens or more of pawpaw bushes.  They look like the asimina reticulata.  From what I have researched the fruit is not as large or tasty as the northern pawpaws, but I am stoked to find them.  https://www.youtube.com/watch?v=I6bK4rjI_ao







Hi Odenwald,
amazing, thanks for sharing. One question: Are the flowers in the inner area dark -violett- black coloured or are they in the inner aree sligthly reddish - brown coloured?
In first case it could be Asimina obovata (Big flower PawPaw), in second case asyou said Asimina reticukata (Netted PawPaw)

Just another interesting information: Your Name Odenwald is the same Name of a nice area not far away from me here in Germany! ;-)

The idea with the flower pot as a holder and fruit collection solution is also very good! Of course, you have to check it regularly, I say at least every two days! I control daily, and if you observe one or more bigger trees, it is worth it anyway, because permanently over two or three weeks, almost daily one or two or sometimes more fruits have fallen off.

This sounds well! If you will decide another solution please let me know, maybe this could be better than mine one. I will than compare the solutions ;-)

If the pollination is successful, i plan to thin to a single fruit per tree due to their size. Of course, that fruit might not hold to maturity.

Before the fruits have grown to their final size and before they are fully ripe, fix them to the branches with nets or mash bags. Put such a net around the fruit, even two or three, as the case may be, and fix the net with a clothespin, a cable tie or the like to the branch where the fruit grows. Bring light tension on the net so that the fruit is supported and no longer hangs with its full weight on its style. Firstly, the advantage is that they will not fall off before they are ripe in stronger winds; secondly, it has the advantage that they will not fall to the ground and be damaged; thirdly, it has the advantage that no animals will eat them or eat them up completely!

This picture here shows how I practice this. The fruits in the net only came loose when they were really fully ripe, and they still hang on the tree ;-)

By the grace of Ulrich ( Usirius) ,i got a Susquehanna pawpaw.Dream come true because this its the orange pulp paw paw i wanted and im sure its verry different from the yellow pulp Sunflower or the whitish pulp Prima i have.
Now i am happy.Its in the square pot.

I am glad that I could help you to get this Special PawPaw - from which Neal Peterson says,"Susquehanna is without a doubt my personal favorite, if I had to choose one."
I also will plant Susquehanna PawPaw in my garden this spring. I'm really excited about the aroma of the fruit, the fruit colour and the fruit size, but we will have to wait another 3 - 5 years - but time goes by faster than you think. Hope they will grow well!

@Triloba Tracker and all:

It is not recommended eating dried pawpaw pulpe.

https://www.petersonpawpaws.com/faq: "What can I do with pawpaws besides eating them fresh?"
"(...) fresh eating of the yellow flesh (not the seeds or skin) is the best way to enjoy a pawpaw. Slice it open, spoon it out, and enjoy, spitting out the smooth seeds as you go. Several favored recipes for pawpaw include ice cream and smoothies, which I find wonderful. Beware however that baking with pawpaws may make you sick. Use caution when baking, try a little bit first and see how you feel before serving the goods to others. DO NOT MAKE PAWPAW FRUIT LEATHER! I have gotten many reports of people vomiting up their pawpaw fruit leather. Just enjoy it the way Mother Nature intended!"


And concerning allergic reaction I am referring to R. Neal Peterson to the topic "Are Paw Paws safe?" https://www.facebook.com/.../5895095.../3598492780264334/...

"Due to its potential for allergic reaction causing contact dermatitis and possible presence of pesticides, pawpaw consumption may be harmful to humans." [wikipedia.org/wiki/Asimina_triloba#Fruits]

Because of that statement, a question has arisen about the safety of eating pawpaws. According to the FDA,

“The pawpaw has a long history of food use and the FDA does not currently have any evidence that pawpaw is unsafe to eat.”
[communication to Dr. Kirk Pomper, Kentucky State University.]

Indeed, some people are allergic to pawpaw. This is not exceptional, however. Food allergies are many, the most common being
milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans. Among fruits the common ones are apple, peach and kiwi fruit. Less common are apricot, banana, cherry, coconut, date, fig, grape, lychee, mango, melon, orange, peach, pear, persimmon, pineapple, pomegranate, prune, strawberry, and tomato.
This list puts pawpaw allergy in perspective. Pawpaws are not unusual; and the same caution should be exercised in eating them as in eating other fruits.

The statement that pesticides are present in pawpaw seems peculiar. Pesticides are not being sprayed on the fruit ― never in the wild, and almost never in cultivation. This claim seems to be a poorly chosen wording, based on the fact, that pawpaw ― and other plants in the Annona family ― contain acetogenins, a class of potent compounds that have pesticidal properties.

Because of acetogenin’s potent bioactive properties, they are being investigated for their anti-cancer potential. Other research is investigating the neurotoxicity, using rat subjected to intravenous injection of purified acetogenins. The toxicity is expressed at higher doses than humans would ingest. The practical implication is unknown since realistic studies in which the pawpaw fruit is ingested have not been done. What is the absorption in the stomach and intestine? How much of the compound is detoxified by the liver? How quickly is it excreted?

We should not be surprised that plants contain toxic compounds. They are the plant’s defense against predation by insects, fungi, and animals. The food plants eaten around the world are full of bioactive compounds. A short list of the notable toxic compounds and their plant are these:
Cholinesterase inhibitors - in potatoes, tomatoes, and eggplant.
Protease inhibitors – in raw soybeans
Amylase inhibitors – in wheat flour
Tannins – in tea, coffee, and cocoa
Cyanogenic glycosides – in cassava
Glucosinolates – in cabbage, broccoli, Brussel sprouts, etc
Lectin proteins – in red kidney beans
Lathyrogens – in chick peas and vetch
Convicine and vicine – in fava beans

Moderation in eating pawpaw is the sensible approach. Consumption of one or two fresh fruits a day, in season, is normal; it is how humans have consumed them throughout the ages, and can do no harm. Daily consumption throughout the year, particularly of a tea brewed from the leaves, is probably unwise. Finally, and most importantly, do not inject pawpaw fruit directly into your veins. "


To avoid allergical reactions as well as possible by eating PawPaws I would recommend not eating skin or parts of the skin. For some people also the fleshy Skin around the seeds may cause stomach issues or allergical reactions.

And of course don't eat the seeds!

Usirius,Susquehanna its what i want to have next.I only have a Prima and a sunflower grafted.
In Romania ,Prima and Sunflower are the only varietyes available.

I do have one Susquehanna available with has a damaged tap root - if you like to have it and shipping to romania is allowed I can offer selling and shipping of it to you.

I would prefer Prima 1216 and Susquehanna concerning fruit size and and the percentage of seeds. Sunflower is worthy due to a well Setting of fruits worthy to be planted (self fertile) but for me ist  fruits are not as tastful than fruits of Prima 1216 and Susquehanna.

@Spaugh - Yes vinegar contains the acid I mentioned. The method you mentioned is somewhat different as I have mentioned and have been practicing for many years. In the method you found, they take besides (only!) 5% wine vinegar other substances that are also organic. In the method I mentioned, which I have been practicing for many years, acetic acid is used exclusively, but it is twice as concentrated as in commercial vinegar, namely 10%. In Europe one can buy acetic acid in 20% to 60% concentration quite inexpensively canister-wise.  Look, concentrated acetic acid is so easily available in your country. If yes, I would recommend my method to you. It has only one disadvantage: Anything that gets overspray other than the peach tree can be damaged, this can be weeds, lawns, evergreen plants of any kind. Deciduous woody shrubs usually have no problem with acetic acid. If you like, I can refer you in the next few weeks to a publication in German by the University of Hohenheim (Germany) on the treatment of peach ripple disease with acetic acid.

qspaugh: There is also a biological control method: Spraying the trunk, all branches and all twigs and buds from all sides with 10% acetic acid. This should happen during the rest period, i.e. from now until mid-January at the latest on a day when it is between 5°C and 10°C and does not rain. The background is that the fungus lives on the bark and infects the buds and the young shoots when the buds swell. Once the fungus is in the green parts of the plant, it is difficult to control it. The best time for very successful control is, as I said, the resting period, which also applies when chemical pesticides are used. For the use of acetic acid as a pesticide, the pump syringe must be suitable (the sealing rings must be made of silicone or EPDM).

Cold Hardy Citrus / Re: CHIRONJA GRAPEFRUIT
« on: December 07, 2019, 01:27:59 PM »
The Chironja Grapefuit is as far I know not a real Grepfruit. It is presumably < hybrid between Grapefruit and Orange, therefore also called Orangelo

It is said that in the year 1956 Carlos G. Moscoso of the Department of Horticulture of the University of Puerto Rico found a wild seedling tree in the rural mountainous Angeles and Caguanas areas of Utuado municipality, which produced large, bright yellow fruit, and other seedling trees were found in isolated areas among the coffee plantations.  The name Chironja is a combination of Chi(na), the local term used for the sweet orange, and (to)ronja, the Spanish word for grapefruit.

In https://citrusvariety.ucr.edu/citrus/chironja_3909.html it is also listed as a Grapefruit hybrid - with the marking CRC 3909.

According to knowledge that it is presumably a hybrif Grapefruit whicht is not hardy and also sweet orange which is also not hardy I agree with you to put it during the winter into inside or into a greenhouse in any case is the safe method - if you can get this citrus variety in your country

« on: November 30, 2019, 01:57:59 PM »
I am cultivating many types of rubus, raspberries, blackberries, dewberries, vine berries and much more  since many years in my garden. The frost hardy ones planted out, the less frost hardy ones are in the pots.
Of the blackberries you mentioned, I have cultivated the variety Navaho for about 8 years. It grows in soil of my garden with ph more than 7. It is extremely vigorous, especially in summers with a lot of rain, otherwise the shoots do not grow so strongly. This year the fruits have dried for the first time mostly before ripening, because we had a very long and very hot summer.  Rubus from temperate zones generally does not tolerate heat and drought so well.

My Citrandarin Poncirus x Changsha Mandarin HRS899 Seeedling (means F1-Generation of HRS 899) do not create seeds on unpollinated fruits. Those fruits ware growing smaller than fruits of pollinated flowers which contains seeds.

Cold Hardy Citrus / Re: Frost Protection
« on: November 27, 2019, 03:15:30 AM »
According to my knowledge and experiences with infrared light bulbs I think they are warming the surfaces (leafes, stems, twigs) too hot. I would prefere normal light bulbs which I am doing for some plants I have in plein air with a simple frost protection, I do not use an thermo cube ecause I am using low wattages (between 3W and 20 W) I can let run them during frost periodes permanently - minimum for night - than switched by a timer - without any danger of damaging. From time to time I am looking at weather news for deciding to swithch bulb of,  or on or to change the bulb, use one  with more or less power.

Interesting thought....I myself have not yet started refining experiments with specifically selected different rootstocks, for example root suckers from different clones. Of course there are weaker or stronger varieties, flowering sooner or later or bearing sooner or later, but to what extent the rootstock communicates this to the grafting is the question. I am already glad, if at all a refinement succeeds to me, is not completely so simple. Maybe KSU has already done research on this, so if someone has a good contact there, he is welcome to ask, I would be interested!
