Tropical Fruit Discussion / What’s wrong with my grumichama?
« on: April 18, 2019, 11:46:01 PM »
I bought a grumichama tree 3 years ago when it was 2 years old from a nursery in GuangZhou. It looked fine when first arriving and I planted it in a big pottery container. However, after a year or two, it hadn't grown too much. The leaves, especially the sprouts looked unhealthier day by day. Some new sprouts even withered before spreading. Just a few flower buds appeared in last March but all dropped down. (no flower bud this year). Last autumn, I transplanted it into a bigger pot and replaced the original soil with something better, finding that the roots didn't develop very well.

There is a sub-tropical mountain climate in my town which has warm but dry winter and spring.The relative air humidity often drops to 20%~30% in dry season. The annual mean temperature is about 17.2 degree centigrade. The yearly precipitation is about 1000 mm. The rainy season usually lasts from late May to early October.

It is said that grumichama tree could only grow well under humid climate which has more than 1600 mm of yearly precipitation. Is that true? Could anybody share some experience or tips with me?

Thanks in advance.

Hello,

From the photos, it seems to me common E.pyrifomis, I needed a photo of the whole plant, I never saw uvaia cultivated in the shade, always in full sun, even in the forest, they get huge disputing sun with other trees.

99 percent of the Uvaia are sour, they vary a lot, on the shape and the flavor generally, it is good but sour, it reminds me of the taste of Eugenia Spitata (Araca Boi), There is a hybrid of E Pyriformis x E Lutecens, which is sweet , but nothing like some guys talk about sweet as honey, is acidic.

All these fruits have a characteristic of rapid fermentation, do not serve to store their pulp, or make juices to consume many hours later, and as soon as you remove the fruit from the tree it becomes soft, almost liquified.

You can make juices, jellies and ice creams, once a Taiwanese asked me for 2,000 Uvaia seeds, to plant and sell the fruit in the supermarket, like a fresh fruit, I made a video at the time explaining about this fermentation characteristics and he gave up this huge amount.

It is a fruit very attacked by the fruit fly.

I really like this tree, it's a wild tree where I live, and every place it varies a lot, in the shape of the fruit and in the flavor.

Hello,

Thank you so much for your information. Here is the photo of the whole plant and I don't know if the pollination has been successful. Let's wait and see.

Is your tree in full sun? I have a plant that looked great until I put it in the ground.
I was giving it morning sun only and then I planted it where it gets mostly afternoon sun and it
hasn't looked happy ever since :(
Yep，my tree is in full sun. The afternoon sun can be very fierce most of the time in the spring and the early summer here. The air is always hot and dry until the rainy season comes in May.
But I only found a few new leaves got sunburned this spring while the whole plant was generally in good condition. As rainfall comes， it turns out to be more healthy now.
Maybe there are some differences between species. I just suggest you use the sunshade thing and make sure to give it sufficient irrigation.
Best wishes.

    Last year, I bought this 3-year-old tree-like plant in a nursery where they called it "Brazilian golden cherry".  I guess they might get the saplings from Taiwan，or get the seeds directly from Brazil by international mails. Anyway, I would say it seems to be a very rare and exotic plant in China. And I'm still not sure it is the E. Lutescens or the E. Piryformis till now.(Any expert to ID it please?)

    Having done some homework, I get to know a little more about it. Maybe several Eugenia species including this one are all called "Uvaia" in Brazil and some other native habitats. I‘m also amazed by the diversity of Eugenia genus （which has over 1000 species).

    To my surprise, it started to blossom 2 days ago. About 30 flowers blossoming at the same time on that rainy day, I pollinated them with a tiny brush pen to minimize the influence of weather, in hope of getting some fruits this summer.

    I remember some guys on YouTube describe the taste of Uvaia as "a mixed flavor with apricot, tangerine and loquat” which is far beyond my experience and imagination. The best way to know the taste of apple is to eat one. So, wish me good luck to have one.

not a fan currently... but your Cempedek may be a cross, wonder how it is ripe with green skin..  in Malaysia many different varieties, some are cross bred with Jackfruit
I don't know much about cempedak varieties, but some varieties with red or white flesh do look so attractive. I wanna try them all. ToT

I have a cemp here in the ground in its second year outside. It may never fruit but it has survived in about the equivalent of 10a or b
Thank you for your information. In my opinion, it could also be planted as an amazing ornamental.

You can try to grow the seeds...
It likely needs very tropical conditions for survival.

    Yesterday I received the cempedak I bought from an online store several days before. I fell in love with its durian-candy like fragrance immediately，which is denser and sweeter than both ordinary durian and jackfruit.
    Unfortunately, this fragrant,spiny fruit turned out to be rotten and inedible when I opened it. However, I still took a bite of a segment from the bottom of the fruit. In fact, it tasted good, as a cotton candy with much more sweetness than tartness. Whatever, it would be my top 5 favorite fruit.
    Now I can't wait to arrange a journey to East Malaysia to look for the true taste of cempedak and other rare jackfruit-related fruits in Borneo jungle.

Hi everyone，
     I come from a small city in Southwest China. As a green hand, I've planted some  Eugenia species，Jaboticaba species and Carica（papaya） species in my garden. My hometown has a sub-tropical plateau climate which always provides us with generous sunshine as well as apparent diurnal temperature fluctuations and uneven rainfall. So I come here to learn from all of you and share the joy of tropical fruit growing.
    Again, I'd like to express my appreciation to everyone, especially the staff behind this forum for your passion and devotion.
   
    Best Regards,
    Guoyang
