Citrus General Discussion / Re: My Marumi kumquat tastes so good.
« on: September 20, 2019, 02:34:33 AM »
This year's main crop is in September. I didn't have fruits in June and July and only a few in August. The fruits, which ripened in April and May were alright. However, these overwintered fruits were not as good as the last summer fruits.
Now, the Marumi kumquat are juicy and taste excellent again. For high quality fruits, regular fertilization and plenty of sun and water is essential.

A nucellar seedling doesn't necessarily give a plant, exact like the mother plant.

A nucellar seedling doesn't necessarily give a plant, exact like the mother plant. There is also a change, it is seedy like the original Triumpf grapefruit, from which the limb sport originated.

I regard the second plantlet as a zygotic seedling, because it is different.

Citrus General Discussion / Jackson grapefruit
« on: September 08, 2019, 12:25:12 PM »
Last summer (2018), I found a Jackson grapefruit in the supermarket. The fruit contained one seed and tasted pleasant and sweet. This single seed gave two seedlings. Last year, both plantlets were thornless. However, since this summer, one of the plantlets develops thorns.

Citrus General Discussion / Citrus IBERO
« on: August 15, 2019, 06:52:26 AM »
There was already an inconclusive discussion about Citrus maxima Ibero in the French citrus forum. https://www.agrumes-passion.com/pamplemoussiers-pomelos-f6/topic3091.html

Since 3 years, I grow a plant, labeled as Pomelo Ibero, and it is in flower now. Propagated by Eugen Schleipfer. All he knows, it came from a citrus trading company, called IBERO. It is either a citron or a pomelo X citron cross. Anybody knows more about this plant?

One germinating seed, out of ten, doesn’t give strong support for the theory of cold treatment. Now, I think other factors are more important for the germination in Campomanesia. Also, Guabiroba, Campomanesia xanthocarpa, treated the same way, didn´t give any germination.

One seed germinated in April, from the batch 2018, treated the same way as 2017. Now, I grow three sete capotes.

Yellow and red Muntingia calabura. Seeds from achetadomestica. Fruits were packed in wet vermiculite. At arrival on my place, the pulp, seeds and vermiculite were a somehow slimy mass. This mass was spread evenly on top of seeding trays, filled with peat. The seeding trays were well watered, bagged and put on a warm place with indirect sunlight. After a week, the trays were taken out of the bag and put in full sun, for 4 days. The peat was kept wet and watered twice a day. Thereafter, the trays were taken out of the sun and bagged again. Seeds germinated a few days later.

After taken this picture, I have potted 50 seedlings. For me, that’s more than enough. However, with colder temperatures in autumn and winter, a high mortality may be expected.

Mike, thank you for the seeds. I appreciate very much, your help and your advice.



How long to reach that stage?
Mine from last year never passed 1mm, some are still alive but same height.
The batch from this year slightly better, around 2mm(only a few) in 2 months ....
In case I can't get even this batch to grow, would you sell me a yellow muntingia seedling next year?


The seedlings are 4 weeks old. If I still have some after the winter, we can trade.

Tropical Fruit Discussion / Achacha from Guatemala
« on: June 24, 2019, 04:18:03 PM »
Recently found in the supermarket.
Price per unit (fruit): 80 Eurocent (0.8 €).
The taste: Pleasantly aromatic and sweet.
The disappointment: Not much to eat. Even very little in fruits containing two large seeds.

Tropical Fruit Discussion / Slow growing plants
« on: May 29, 2019, 10:17:06 AM »
Growing plants from seeds, often, there are some plants, which grow faster than other plants. Also, sometimes there are plants which grow exceptionally slow. Previously, I thought these slow growing plants are somehow a special form and gave extra care. However, perhaps, the only exceptional feature of these particular plants is the slow growth rate. Did you experience the same? Did you coddle such a plant for many years? Was it worthwhile? Does grafting normalize the growth rate?

Plinia pithrantha ESALQ. The fastest and the slowest plant (10 cm square pot). Germinated in January 2016.

I bought this hybrid of Citrus (Eremocitrus) glauca and a mandarin from Eugen Schleipfer, three years ago.

Citrus General Discussion / Eremomandarine
« on: May 05, 2019, 04:52:46 AM »
As announced in the untraceable Eremolemon thread, here are pics of my flowering Eremomandarine. The flowers are small and the plant has a few fine prickles.
According to   https://www.agrumes-passion.com/agrumes-oceanie-f90/topic3092.html
Eremomandarine is not the same as Eremocitrus X Shekwasha.

Tropical Fruit Discussion / Re: Cerrado Cashew (Anacardium humile)
« on: April 29, 2019, 03:47:36 AM »
Wikipedia tells about the climate of Puerto Rico. Even in the coldest months, January and February, the temperature minimum is 21 °C (70 °F).   A wet autumn is followed by a somewhat cooler season with considerably less rain, from January to April. Caesar, this may have helped your plants to survive. Very interesting to know, that your plants survived continuous watering throughout your cooler season. However, Luc reported, his plants didn´t survive continuous watering on cooler places, like Puerto Vallarta.

Thank you to all, who have supplied information. Now, I believe to know, what caused the death of my plants. Certainly, the soil was not too wet. Further, it is unlikely, it was the drought. Responsible is the cold. As a tropical plant, roots are incapable to sufficiently supply the shoot at temperatures below about 15°C (59 °F). After 12 weeks of persistent temperatures, not much above 10°C (50 °F), hardly ever exceeding 15°C, the shoots withered and the whole plants deceased. The room was kept a few degrees colder, than the year before.

Citrus General Discussion / Re: My Marumi kumquat tastes so good.
« on: April 22, 2019, 04:29:43 PM »
For me, Marumi is a spring, summer and autumn fruit. Last year, the tree flowered all summer long, and went dormant from November until March. Only a couple of fruits ripened during winter.

« on: April 19, 2019, 04:44:14 PM »
My last two plants are gone. It was in early January that the leaves dropped, one after the other, within about 14 days. With only a few leaves remaining, I finely decided to give some water. This had no effect. With the last leaves falling, the numerous dormant buds on the xylopodium died as well. This was a great surprise to me. I did expect that the dormant xylopodium would not be effected by the drought. The sparse watering at the end might not be responsible for the death of the xylopodium, because there was no rot. The whole plants desiccated. The plants were on the same window sill as the winter before, with a temperature minimum at around 10 °C (50 °F).
 I have no idea what I did wrong. There is still no information about the dormancy of Anacardium humile. The only information, I could find: Luc´s plant enjoys an 8 months dry season.

http://tropicalfruitforum.com/index.php?topic=6209.msg81895#msg81895

I am somehow frustrated, but I don´t give up. Luc, please send me a few more seeds.

Caesar, how are your plants doing?

Temperate Fruit Discussion / Re: Arrayán, Luma apiculata
« on: April 13, 2019, 05:50:07 PM »
The Arrayán were harvested, today. The fruits are rather dry, mushy and with lots of seeds. Slightly sweet, but tasteless. Nothing to enjoy. Interestingly, the fruits lost all of the bitterness. Possibly, this is due to the frosts. The plant had many frosts down to -6°C (21.2 °F), occasionally -7°C (19.4 °F), without any damage. However, a Luma chequen, next to it, lost some branches.

« on: April 11, 2019, 04:14:03 AM »
Now, that I have tasted all of my kumquats, I can give my assumption of the taste. Meiwa and Changshou are very good fruits. Centennial Variegated still is a good fruit. However, it is missing some of the flavor, which makes kumquats so special. I also like Nagami, but my favorite kumquat still is Marumi. This is, may be, because I had most of the Marumi in summer and the other fruits during the winter months. More sun results in better fruits. I only had a few fruits and no direct comparison, eating them one at a time.  Therefore, I may change my evaluation in the future.

Centennial Variegated and Meiwa

Hi Solko,
great to have a Luma chequen, growing in ground. Good to read about its edibility and your confirmation of its hardiness. My plant hasn´t flowered yet, but may be in the next season.
Thank you for the link. I have tried to order from Arven Pepinieres. However, only addresses inside France will be accepted.

Is this the only cold Hardy myrtaceae you have? What kind of potting medium is being used?
I grow several Luma, Ugni and Myrteola. All are similar hardy and get the same treatment. Young plants grow in peat, with a bit sand. Larger, flowering sized plants, enjoy a more mineral mix. This particular plant grows in a mix of pumice, vulcanite and zeolite, around the original, peat based, root ball.

Temperate Fruit Discussion / Arrayán, Luma apiculata
« on: December 08, 2018, 10:30:33 AM »
Luma apiculata is one of the Chilean Myrtaceae, which is planted worldwide, in many similar climates. This is because of its beauty as a tree and also for its edible fruits. Moreover, it can take some cold and is hardy to USDA Zone 9.

My container grown Arrayán flowered profusely in July, and nearly every flower set fruit. Despite, we had an unusually warm and long summer, the fruits are still not ripe yet. The fruits are slightly soft. However, ripe fruits should be black, not white.



The plant is still outside. Several slight night frosts in November, around -3° C (27°F), did not harm the plant, nor the fruits. If the nights become colder as -6°C (21°F), I will put the plant in the garage. If the day max temperatures will stay prolonged below -6°C (21°F), the plant will be moved in the basement. Because the basement is too dark and too warm, the plant will be moved outside, or in the garage, again, as soon as the weather allows. This worked in the last years. The last winters, the plant spent around a few days, up to two weeks, in the basement. About two or three times, during a winter.

Usually, Arrayán ripen in autumn. However, in the web, one can find pictures of ripe fruits and flowers on the same plant. Therefore, I hope the fruits will ripen in spring. I have picked one fruit. At the first glance, the taste was very pleasant. However, a fraction of a second later, almost simultaneously, the fruit was extremely bitter. Definitely unripe and unpalatable.

Theodor, thank you for your advice. I will watch the stem very carefully for any rot on the base. If necessary, I will try to propagate a cutting. Careful digging, did not yet reveal any rot.

I have had a Babaco in 2016. It rotted in winter, even kept fairly dry and frost free, on a window in a cool room. This year, a new plant was planted in the garden, where it did very well during summer. In October, it was potted for the winter. Since then, I have watered only very sparingly and the plant is starting to shed its leaves. How dry can Babaco be kept, leafless in a cool room, during winter? I plan to plant it in ground again, in spring.

Citrus General Discussion / Re: Snek ́s citrus container plantation
« on: November 09, 2018, 03:34:18 AM »
Snek, you are the champion. Leaving everyone else far behind. You show what is possible. Even in a not so favorable climate and with limited space and resources. After reading your posts, I always have the desire to buy more citrus trees. Never thought, how fruitful and rewarding citrus in container can be.
