Cold Hardy Citrus / Re: Nippon Orangequat - cold hardiness
« on: January 20, 2022, 07:27:03 PM »
Yes Brian, my fruit looked satsuma like and tasted satsuma/orangelike, lower acid than my satsuma myagawa.
Think I will take a small twig in spring for grafting on citrumelo or poncirus and then will test frosthardiness.

thank you, thats a very interessting information, cause I also thought if it would be worth to graft on fast flowering poncirus to get immature seedlings earlier to flower and fruit.

@all, thank you for your comments.
But believe me the fruit was really delicous comparable to a satsuma.
My plan is to take a small twig of the plant and graft in on poncirus and plant it later in ground, but I guess protection and heating in zone 7 will be necessary if temperatures lower than -10 or -12 Celsius ( 10 F).

Thanks Poncirusguy, I think there are several cultivars under the name Orangequat, mine is a cross of mandari x meiwa kumquat and so the fruit tastet realy delicious.
But I think hardiness is therefore also limited for planting in ground at my zone 7 place, without more protection.

Vlad, I have done this several times with seedlings between 6 weeks and several months and it worked with a high success rate, most difficulty to handle the small seedlings and to put the ligature. I took on both scion and rootstook only some leaves away to have place for the cleft graft, but not all. I thought the small plants still need their leaves.

interesting experiment, but did you insulate the pot by testing ? Because a plant in earth ( with better insulated roots than in a pot) will take more cold temperature I assume. Regards Frank

Cold Hardy Citrus / Nippon Orangequat - cold hardiness
« on: January 14, 2022, 05:32:15 PM »
Tuesday I got an Nippon Orangequat with a really wonderful fruit, 6cm in diameter, wonderful mandarinorange flavour and very juicy, delicious.
I read it could take down to 10 F.
Does anyone cultivate this wonderful plant and what are the expiriences concerning cold hardiness and other specifics of the plant. Thanks Frank

Hello Poncirusguy,
interesting experiment, I have a poormans orange also called   Newsealand Grapefruit which is called to need lower amounts of summer heat for the fruits than normal grapefruit, but I guess Newzealand lemonade is an other citrus variety  ?

Hello SC4001992,
wonderful pictures you posted of your tree, very good for comparison. Due to beeing a nearly newcomer to citrus,
I don' have so much fruiting harvest yet, but I can share pictures of my Tangelo nova and  Keraji with first fruits of the plants, riped final from october in greenhouse, but I was very satisfied with the taste for my not real citrus climate conditions in zone 7, Germany  ;D.

above pictures tangelo nova, perhaps not 100% ripe, due to more green than orange rind, but already very good aromatic taste and good sugar acid balance.

Keraji mandarin, first fruit of one of my first grafts, already good ti eat, but perhaps it would have gotten more sweet a few weeks later. Was already sweet but a little bit more acid.

Hello Ilya,
very interesting cross, are there some new informations about fruit specifications as taste, size, month of ripening,.. in the last two years 2020 and 2021, would be interesting - thank you.
Regards Frank

« on: January 01, 2022, 05:11:17 PM »
Congratulation Kumin, first ripe fruits from your cross, looks encouraging.
Regards Frank

While up to now our winter is not to cold, the coldest period have been 4 days with temperatures at night with about 20 F (-7 C).
But this is still not the end of our winter, due experiences of the last years, the most challenging months in the last years have been January and February. Today and the next days we have temperatures of 48 - 57 F ( 9- 14 C ).
Nevertheless its always interesting to gather informations about winter protection strategies in our cold climate (for citrus), so quite interesting to read the article in the link  below, perhaps also interesting for some of you.
Regards Frank

interesting informations, up to now I can confirm very good frosthardyness and very strong revitalization ( with passive protection supported last winter -16 Celsius with about 50% twig damage, but came back in summer to about 3 times size as before winter).
A second plant in pot had a fruit and this shows also the slow development of fruit ripening.
Curious how the in ground planted will manage the 2 nd winter and if now there will be a chance of flowers and fruits ?

Winter preparations (first step sun protection with fleece) finished.
For Ichangensisxsinensis and Satsuma Collot a 80 Watt heating cable is installed if temperatures exceed -8 Celsius for several days it will be connected and additional isolating material as now on the top will be wrapped around.

the hardier citrus with sun protection. If cold spells are deeper than -10 Celsius for several days are announced, an additional cocosmat will be also wrapped around.
This year there is a new citrus CitrumeloxYuzu in ground, lets see how it will go over the freezing period.
Last years January to March are the periods with deepest temperatures.

regards Frank

thank you very much Jim for your detailed interesting information to your varieties I appreciate this very much.
And for me as a nearly citrus beginner compared to you and other long cultivating citrus experts these informations are very helpful, especially in our challenging climate for in ground planted citrus in middle Europe.

Very interesting fruit comparison Jim  :D, how old are your mandarin trees, and in which age/ size did your Changsha and Citsuma Prague fruit for the first time ? I also have them in ground and so I' m glad to hear that Prague tastes very good.
Best regards Frank

Looks very nice Brian, good to hear that it tasted sweet and juicy. Mine are still more green than yellow - its hard to wait  ;)

Thanks Andrew, yes this is perhaps possible also with the late maturing. I have a Satsuma miagawa in pot , this variety works in my climate and I had delicious fruits last year begin of November

Congratulation Flo, looks great your tree with fruits. For me as also cold hardy citrus cultivater its only a pity, that our species (cold hardy citrus cultivater) is so rare, that fruits of the different cultivars are so seldom, that we not often are able to compare fruits and taste of cold hardy varieties. So your taste test and sharing of this is very appreciated, thanks a lot . And good luck for fruits with your tree planted in soil.

Interesting Discussion - but anyone with fruits, pictures ? Taste ?  ;)

Cold Hardy Citrus / Re: Taste Test
« on: November 30, 2021, 12:34:05 AM »
interesting taste test :P.
It leads me to two questions:
1. Owari seems not to be as good as his assumed reputation. I have a satsuma collot which shall be a kind of owari.  Does anywhere cultivate satsuma collot and what are the experience concerning fruit quality and frost hardiness ?
2. Bishop citrandarin seems very promising , Does anywhere in Europe cultivate Bishop citrandarin and what are the experience concerning fruit quality and frost hardiness ?
Thanks Frank
