I decided to keep it inside for few weeks until it turns to yellow.

Ponderosa is not true from seeds.

No, I missed its flowering.
The season was extremely hot and dry, my other inground citruses are rather late this year, probably due to the lack of water.

We expect first night freeze this week, so I decided to harvest this fruit.




Still partly green, 177 grams of weight.

I have Kabosu from the budwood that I got from Roberto. The leaves are less round and have some suspicious wrinkles.

As mentioned above, I got the seedling's budwood  from  Robert .

Not really, but it is much larger now.





We have not yet had any frost by now, will pick it in the beginning of December.

First 5* Citrumelo mature fruit sampled on 3 year old trees. The fruit has just begun to change color. I didn't expect much of the fruit, but it was sweet as well as acid and had a noticeable grapefruit flavor. There was a bit of bitterness
similar to grapefruit. The fruit was approximately 4 cm (1 1/2") in diameter, quite small. The Brix was 12.



When high grafted onto Poncirus the scions have survived and recovered after a low of 5F (-15C) during the past Winter.
I guess the fruit size will improuve with the age.
Below are the fruits from my 20 years old tree harvested today. The season was hot, 12 Brix, practically no perceptible internal oils, good lemonade when diluted three fold.

It is a damage caused by  citrus flower bud mite Aceria sheldoni

1rainman,
Your post is a very good demonstration how different are requirements for citrus growth at 28 and 48N.

My plant has been in open ground for 7 years, no protection, no damage. Fruiting is rather shy, this year no harvest because of extremely dry and hot summer.

Ilya how does Poncirus+ fruit size compare to other Poncirus fruits you have? Mine are markedly smaller. But, perhaps due to low seed count?
For me there is not much difference.



Three fruits of PoncirusPlus and two of SwampLemon:

Fruits PoncirusPlus grafted on FD are almost ripe, but  still attached to the branches.

Yes, the first one is definitely a Prague.
UnshiuXJunos is probably a variety of Yuzu found  in a public garden in Yalta, it is also known as Yaltinsky hybrid.
Original tree is very resistant, its fruits are exceptionally aromatic, but otherwise indistinguishable from Yuzu.

From what I know the patogenic bacteria has not been yet introduced in Mediterranean.
Only small numbers African psyllid vector T.erytryae  has been found in Portugal and in few hectares of citrus in Israel Asian psyllid D.citri was reported this year.

They do stay for almost entire winter outside. Coconut coir drains perfectly, never had any problems with roots.
I guess perlite is good, but has a tendance of floating to the surface, while pebbles should be as small as possible.
Seramis pebbles are among most suited link

I am using Lux Meter Level application on Android device, I guess there is also an equivalent for iphone. For seedlings 5000 lumens is OK for growth, mature plants will need more.

Do you have any other recommendations for something that could be better?
Perlite is a good alternative for pumice. Also small clay pebbles.
I personally prefer to use 1:1 mixture of coarse cheap compost  and coconut husk mulch (in France it is sold as Paillage Coco). I  wash it several times with tap water to remove sea salts and equilibrate it with Epson salt solution. Coconut coir is porous and  is  a good exchanger for both cations and anions that prolongates  fertilizer action.

If you mean a pumice for lava, it could be OK, but at least  in France lava is something else- red colored stuff obtained by grinding of volcanic rock.
It is considered unsuitable for citrus cultivation because of high abrasive action on the roots.

Some are fruiting, would any of these naturally cross with my FD?
Of course, potentially there are no insurmountable barriers between these varieties.
But usually one will need an excess of foreign pollen to achieve hybridation. And again, poncirus varieties are usually flowering few weeks ahead of others.

Potentially, it is possible to find such a hybrid, FD is giving a decent proportion of zygotic seeds.
But at least in my area,  there is not much  overlap in flowering time between these varieties.
Also, the lack of bees in early spring could be a hindering factor.

It seems that A-026 was in a frame, was it flowering also in April?

Thank you,
But when PT was flowering this spring?
My plants usually flower at the middle of April, now fruits are almost entirely yellow.

Kumin,
Are fruits of poncirus already ripe in your region?
