Cold Hardy Citrus / Re: Is this sun scald?
« on: March 18, 2023, 10:21:14 AM »
This is what ended up happening to the prague stem with the sun scald. The back of it still has some green. The lignified stems on the Prague have minimal if any damage

I have two grafts one on pure poncirus and one on tai-tri. The tai-tri grew vigorously.

So far both grafts look alive in zone 7a after lows of 1f and 5f. The one grafted on pure poncirus, 2 years old, grows very slow.
After 1 year the graft on tai-tri is twice the height.

It's said to be a chimera of flying dragon and satsuma, the lanky habit probably comes from the flying dragon. I will update more in the late spring to be sure that they are actually alive. 


I've actually tried to grow this from seed and failed, I'd love to try some cuttings PMed you :)

It's a chase card

@ K-Rimes a good example of just that, my thermocube which is made in the USA, fell apart after unplugging it with prongs in the outlet. Was never touched for the whole season until I had to move it. I'm on my 2nd one so they have $30 from me haha (yes they are going for $15 everywhere now). They own the patent so have to deal with it but if I find a Chinese clone that works reliably I won't think twice about it now

Persimmons can cause bezoar / stone in stomach if eaten at the wrong stage of ripeness

Nagami does it for me, store bought ones that look ripe colorwise but aren't. My homegrown ones don't have the same effect

Kumquats create a tingling sensation similar to szechuan peppercorns

Never knew that! Been thinking about getting a kumquat tree and this is all the more reason

I have a 'Meiwa' and it has never caused any tingling effect when I've eaten the fruits.

Is this effect limited only to certain cultivars of Kumquats?

Here's the seedling that survived all winter with low of 1f/-17.7c, pic from this afternoon

Expect it to last just until after the warranty expires. I found an infinite warranty glitch, I use a credit card which adds an extended warranty. When the thing breaks down, the credit card company refunds it after I file a claim with documentation of the product failure, the catch is you have to re-purchase the item or something of equal or lesser value to replace it lol. The warranty resets since it's a new purchase.

Just an update, we had another polar vortex 1f/-17.7c.

The kadsura seedling is still alive! So this seems like a zone 7a plant for sure, at least to the ground level since the upper part of the plant did get damaged as shown in my previous photo. There are healthy green buds below the damaged leaves which will grow out in the spring.

We got down to 5f for a few hours one day and then again 1f for a few hours later on. My tai-tri and citrumelo unprotected look alive, just some tip damage on younger growth. Prague grafts on taitri and poncirus look ok, some brown spots (maybe mandarin cells damaged?). Ninkat x poncirus lost youngest growth but otherwise alive. all poncirus+ and precocious poncirus is alive. yuzu is dead to the base again. morton graft on citrumelo dead, morton on tai-tri looks alive.

I'm not sure which variety of Yuzu I saw when I was in South Korea at outdoor market, they were labeled "Yuja". They were way bigger than what I have. I would buy Yujacha in jars which I'm sure came from those fruits as Yuzu grows in the southern parts of South Korea. "Cha" is tea, the fruit is preserved by making a sort of raw marmalade that you add boiling water to and then drink it.

Maangchi, a youtuber, shows how she makes the Yujacha. These are the Yuzu I saw. When she cuts the fruit in half there is more flesh inside than what I remember mine looking like.

How are your fukushu x pt doing? I've just planted out my nagami x pt+. Hoping to see a hybrid when the seeds germinate.

Yep, here's mine (assuming its the common variety in the US). Not very big but these were also the first fruits 1 year from the graft date.

The rind is edible and the juice is pleasant, acidic but with hints of grapefruit and even mandarin. Used in recipes or combined with sugar it's even better. The fruit is very seedy but the rest of it makes up for it if you can find a use for it.

Thanks poncirus guy. My other plant from that nursery came with gummosis.

So I will defintely be changing the rootstock over to poncirus since that is what I have.

What do you think I can graft on the SCS rootstock? It's a type of sour mandarin.

Interesting! So I am thinking now to graft poncirus on the citrumelo and attach it to the meiwa, eventually cut the citrumelo graft part off and leave the poncirus as the interstock just so I don't have to start over and because the citrumelo grows more vigorously than poncirus I'd prefer to keep it

« on: February 26, 2023, 01:40:10 PM »
That's also a possibility

Luckily I grafted a piece to citrumelo but I am also reading that it's not compatible with Meiwa. Same growing conditions but no sign of fungal or bacterial infection. I did actually find a field report about meiwa on citrumelo which died after 5 years so not sure on this as a rootstock either

Meiwa on citrumelo

Citrus General Discussion / Meiwa scion died to graft point

My 3 year old Meiwa started browning and died back to the graft. Never exposed to cold and over wintered in my grow tent since I had it.

Scratching the bark reveals a brown ring at the graft point. The rootstock used is a type of mandarin.

Is this rootstock incompatible? The rootstock looks fine and was pushing buds on the trunk but I rubbed those off before the meiwa totally died back.

Today was a real test since it's very sunny. I found that I have to glue the panels in place as two were blown out in the yard this morning despite using the supplied clips to secure them.

Yes the anthocyanin in plant description refers to new growth.

Btw YouTube has built in auto translate for videos, but it has to be enabled. Click the settings cog on the bottom right and you should see an auto translate option for your desired language

No need to worry, my edulis from seed makes the typical white flowers but pigmented with purple as well as the anthers. Basically what everyone else is saying, seed grown variation perhaps. The fruit is still just as good

Here's some of the hystrix hybrids (don't know what recieved pollen) there's x genoa lemon, x kumquat, x limequat :

x Genoa lemon

x Genoa lemon (some anthocyanin in new growth less than lemon and makrut)

x Genoa lemon (the most makrut scent, darker growth, no winged petioles)

x Nagami kumquat (no anthocyanin on new growth, no makrut scent)

2nd plant of x Nagami kumquat (some anthocyanin, no scent, bigger leaves)

x Limequat (no anthocyanin, no scent)

Sounds like a nice and knowledgeable guy on Youtube. It helps if you speak Spanish ;D. I would certainly like to see the crosses involving Citrus hystrix.

Cold Hardy Citrus / Plants for unheated greenhouse
« on: February 10, 2023, 02:27:36 PM »
I am building a small hobby greenhouse, it will be unheated and will have 2 automatic venting windows and perhaps a solar powered fan.

Can I plant a small flying dragon inside with poncirus hybrid grafts and keep it inside all year? Will the temperature extremes in the winter kill the tree? How about a feijoa/pineapple guava.

My concern is with the sun shine in the winter it would bring the greenhouse way above freezing, but then night time plummeting to freezing again  Will this kill the plants long term?
