My suggestion is to control the heat source by thermostat.overheating is as detrimental as freezing.

Have there been any discussions on next year's location?

Having large populations likely contributes to encountering them. I also attribute encouraging early , tall growth to the transition from vegetative to reproductive phase in a shorter time. However, not all the seedlings responded in the same way.

Photos of a larger 5* Citrumelo found on a tree that was overlooked earlier.





3 year old Poncirus seedling with a small fruit. If this tree fruits again in the coming year, I may consider it somewhat precocious.

I have a few seeds but they're hybrids with Meyer lemon and I plan on keeping them. Scions in the Spring are not a problem. You can contact me in late March if you wish.

Multiple embryos per seed is certainly a good indicator of polyembryony. Very rarely there may be twinned zygots, but unlikely on a small scale.

Planting the seeds could give a clue as to being Grapefruit vs Pomelo. Grapefruit seedlings exhibit a great deal of uniformity, as the majority are clones of the parent tree. Pomelo, by contrast tend to have no cloned seedlings and exhibit variation in the seedlings.
If you have access to the parent tree, a controlled pollination of a number of the flowers by a pollinator with distinctive foliage could make the identification easier.

Due to impending freezes, most of the 5* and Poncirus Plus fruit have been harvested. Both have small immature fruits remaining on the trees.

Largest 5* Citrumelo.


Most mature 5* Citrumelo



Poncirus Plus fruits.


Fruits off one 3 year old
5* Citrumelo tree. 2 fruits were removed earlier.

Diluted and sweetened Conestoga 026 juice. Taste is similar to lemonade.
2 of the persons taking part of the taste test commented on hints of grapefruit flavor.

I've noticed all the fruits in the cold frame are rather small. I'm waiting for the outside trees to fruit. They may be larger.

Do you do budding/grafting? If so, what time of year is most suitable for you? I have mature, fruiting material.

Last year's fruit were very small having developed from a Summer bloom. All the seeds appeared to be nucellar. I saw no variation in the seedlings, but there may well be some in a larger population. The flowers contain adequate, viable pollen and could serve as male parents.

Seed count from one 026 fruit. Seed count is higher than last year, but the fruit size is also larger. There are a few more empty seed coats than I found in Poncirus.

The fruit ripen at the same time as Poncirus and about 1-2 weeks before Poncirus Plus. The largest fruit was 5cm in diameter. The smaller ones about 4cm, not really larger than Poncirus. This may contribute to early ripening?
In regards to hardiness, there was a small amount of bark blistering in Winter on the southwest side. Dilute white latex spray on that quadrant of the trees may be helpful. As the trees grow larger it may not be an issue.

I've been able to taste test one fruit each of Poncirus Plus and Segentrange Conestoga 026.

Poncirus Plus:
More bitterness
Brix 11
Rind 4mm thick
Smaller fruit 7 seeds
Less wax
Acidic

Conestoga 026:
Brix 12
Low bitterness
2mm rind
More wax, but little taste to it
Acidic

When diluted with water and sweetened,I preferred the Conestoga 026 flavors.


Poncirus Plus very small fruit due to inadequate foliage to support the fruit.

There are 4 fruits on my seedling trees. As they ripen I'll comment on any observations. That being said, I haven't gotten excited by Poncirus rinds to this point. Maybe there'll be a surprise?

I'm not planning on any mass trials, although it may be a great challenge, provided the percentage of zygotic seedlings is high enough to make it feasible. My plans are more along the lines of using it as a parent in crosses with Citrandarins of Changsha parentage as well as the selections from my Citrange Winter trials.
I suspect this tree is a zygotic seedling due to it's precocity.

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.

Genetics are an important factor. Limes and kumquats are reported to be precocious. Grapefruit and Sweet Orange take longer,with Mandarins being intermediate. Citrumelos, despite being Grapefruit hybrids can be precocious. By virtue of close planting within a cold frame, my plants responded by quickly growing into tall plants. This seemed to promote early flowering, but only affected some of the seedlings.
A height of 3 meters seems to trigger a percentage of the trees to flower. It's also possible that having the tree tops hit the polyethylene film ceiling, then deflecting to the side accelerated the transition to maturity. The peak of the ceiling is 3.2m in height.

PoncirusPlus fruits beginning color transition. These fruits are unusually small and may have low seed counts. Nevertheless, there should be an opportunity to taste the fruit. These trees are 3 years old. 2 out of seven trees bloomed and fruited. All the fruits are undersized, but conditions were not ideal during the flowering period. However, Conestoga A-026 flowered successfully during the same period.




5* Citrumelo fruitlets on 3 year old trees. These are the results of late Summer blooms. There are also fruit from Spring flowers, but they're obscured by vegetation, including thorns.

Pruning back the top is counter productive. Here's an example of a tree approaching maturity. Perhaps the uppermost side branches will flower, if not, next Spring's side branches developing above the present side branches will have increased chances of doing so.



Three year old Citrumelo trees that have transitioned within the past year. Three years is rather precocious.

Thanks Ilya, I'll check the seed count on mine in a few weeks.

Ilya how does Poncirus+ fruit size compare to other Poncirus fruits you have? Mine are markedly smaller. But, perhaps due to low seed count?

Branches developing secondary and tertiary sub branches, branches becoming more horizontal are indications of phase change. These fruits developed on a 4 year old tree. There are variables including genetic ones.

The problem with citrus indoors is spider mites. I spray them with neem oil solution or haul them outside once a week if not freezing and blast the underside of leaves with hose.

After using miticides with inconsistent success in the past within a cold frame environment, I eventually went to mist lines just below the poly covering. Although there's an occasional mite seen, there's no discernable damage. The mist lines also serve as Summer cooling equipment.
