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

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
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.

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.

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.

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.

Citrus General Discussion / Re: My Marumi kumquat tastes so good.
« 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.

« 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.

Don't you want to try to induce flowering?
I don´t have the skills, doing it.
If you cut these "early flowering" grapefruits after first year flower to just few centimeters  above the soil level  , they will again flower  next year on the tops of the shoots emerging below the cut.
That sounds incredible. Imagine, if you cut every year. What you will get in 20 years?

My early flowering Oroblanco/Sweetie seedling grows fast and very well. However, I grow two almost 4 years old seedlings, which are very slow. The larger of the two seedlings, just measuring 24 cm. It would be interesting to know the ploidy level.

Almost 4 years and measuring only 24 cm.

Tropical Fruit Discussion / Re: Cerrado Cashew (Anacardium humile)
« on: September 28, 2018, 02:42:26 PM »
You are in a tropical climate and Anacardium humile should do fine on your place, if protected from autumn (?) and winter rain. The plants stay small and protection should not be a problem. Unfortunately, there is no information about the dormant habit of this plant. Kimi from Western Australia has grown Anacardium humile successfully, from seed to flower in about one year.
Wish you good luck with your plants. Please let us know about your future experience.

Tropical Fruit Discussion / Re: Cerrado Cashew (Anacardium humile)
« on: September 25, 2018, 03:57:56 AM »
This is my experience with Anacardium humile. I germinated 20 seeds in 2016. Seeds of Anacardium humile, obtained from Luc Vleeracker, usually germinate close to 100%.  Already three days after sowing, the sand above the seeds stains dark and within seven days all plants are actively growing. These plants are very fast to come into life, but can be very fast to go. During the warm season, I grow my plants in a hoop house, with both ends permanently and entirely open for fresh air. All plants developed well until the end of summer. My first plants were dead in October, and by November, they were all gone. Dead, despite I watered very sparingly, as the autumn days became colder. 2017, I asked Luc to send me five seeds, only. I didn´t want to see 20 dying plants again. All five seeds germinated within a week, grew fast and looked happy. In September, before the first cold days approached, I potted four plants in a planter box with a water reservoir. The idea was, not to water the plants for the whole winter, so the roots stayed dry. However, to have some moisture in the subsoil. This would be a similar condition, like the plants would enjoy during the dry season, in its natural environment, in the Cerrado. I moved the planter inside the house in a room, heated at around 15°C (59° Fahrenheit) during winter, on a south facing window. In the planter was no space for the fifth plants. So I decided to keep this plant still in the hoop house, as sort of a control. Even, kept fairly dry and protected from frost, this plant was dead at the end of October. The other four inside plants still showed some grows, but stopped growing at around November, and started slowly to shed leaf after leaf, during the winter. By March 2018, the last leafs fell off. However, the stem itself was green, with a well-developed xylopodium at the base. All four plants leafless, but still alive. Some stems started to dry at the top. During a warm spell in March, on the now fairly warm and sunny window, several buds, situated mainly at the xylopodium, started to burst. Now, I decided to water. Was it too early, or was it too late? Anyhow, the weather became cool again and the shoots aborted. Moreover, the stems showed even more dieback. In April, two plants were dead and two plants alive and growing new leaves.

In May, the planter was moved in the hoop house again. There was no fast development in the second year. Did the plants change its character? Now, the plants grew fairly slow. Maybe, I didn’t I fertilize enough? I am not sure about this. The two plants grew steadily and gained more than its former strength.

Now, that winter is approaching, I am worried again. Maybe, it wasn´t a good idea with the planter. In a normal pot, soil moisture could be better controlled. Today, with the first cold day, I have moved the planter inside again.

In summary it can be said, that Anacardium humile likes a well-draining, acidic soil and plenty of water, as long as the plants enjoy a warm and sunny environment. It is a true tropical plant, which can survive colder temperatures in dry dormancy only. In nature, dormancy is initiated by shortness of water. Cold means for Anacardium humile, day max temperatures below approximately 15°C (59° Fahrenheit).  Wet and cold, soon results in dead plants. Furthermore, the demand for dormancy is genetically fixed. Anacardium humile would not survive either, in all year warm, wet tropical biome, unless protected from rain. The large seed enables the seedling to a rapid growth. Seedling plants can survive the first dry season only, if established a large enough root system and xylopodium.

I do have a request. Luc, can you please show us a photo of your plant at the end of the dry season? Does your plant shed leaves during dormancy?

June 22, 2017. Seven days after sowing. Five seeds gave five plants. Garcinia seeds in the other pots, took much longer.

September 08, 2017. Not even three months old. The planter was moved inside.

September 24, 2018. The left plant regenerated from the xylopodium, only. This plant developed several new stems, none as tall as the one last year, and a strong xylopodium.  In the other plant, the whole stem survived, beside the very top part. New leaves emerged from the stem with an additional shoot from the xylopdium. The moss shows, that the plants were watered almost every day, during summer. There were seeding trays on top, beside the dead plants. The planter was moved inside, today.

September 24, 2018. The above part of the xylopodium of the left plant produced many dormant buds. The xylopodium of the right plant looks similar, but is not as thick.

Tropical Fruit Discussion / Re: Yay! My first pitangatuba fruit!
« on: August 22, 2018, 03:18:02 AM »
My pitangatubeira produced the first two flowers this June, with the second flower setting a fruit. Seeds from FlyingFoxFruits.
The fruit fell off, during preparing the photo.
Very nice flavor. Not too sour at all. The only drawback is the large seed.

My nashi pears ripen in August. A dwarfish tree, less than 2m. Approximately 25 years old. Doesn´t bear every year. Variety unknown. Possibly Shinseiki. Sweet and very juicy.

Luckily, I grow 2 sete capotes seedlings. Still very small, but exciting. This is my experience: 10 seeds from Marcos arrived in May 2017. No germination in 2017. I complained to Marcos about it and Marcos send my 10 seeds for free with my order in 2018. Thank you Marcos for your generosity. 10 sete capotes seeds were sown again in April 2018. In May 2018, 3 sete capotes seeds germinated, sown in 2017. This was unexpected to me. The seed tray was in a corner of the glass house, regularly to occasionally watered, but somehow neglected. As I discovered the seedlings, one of the seedlings was too dry. This seedling didn´t manage to get out of the seed coat and died. The seed tray was inside a glass house for the whole year. Warm to hot during the summer and not much above freezing temperature for 3 months during winter. Because 3 seeds germinated in spring, after experiencing cold temperatures, this indicates that stratification may be favourable in germinating sete capote seeds. No germination yet, of the seeds sown in 2018.

The plant on July 03, 2018

Like last year, the flowers of my plant did not develop further, as shown on the picture. Ilya, can you conform its identity, even without an open flower?

Tropical Fruit Discussion / Re: A wealth of different types of Uvaia
« on: June 07, 2018, 02:23:07 AM »
Solko, your plants are very well grown. Congratulation. In our temperate climate, it is not so bad after all, to overwinter inside. The plants flower much earlier, if they experience warmer temperatures during the winter. My precocious plant flowered only in mid of June, last year. No flowers this year. All of my Uvaias look glabrous at first glance. However, observed with a magnifying lens, the leaves have short hairs and are fairly pubescent. Taller, faster growing plants are less pubescent than the smaller, slower growing plants.
