hand pollinate, that will give you the best chance for fruit.

Mulberry trees can look kind of rough this time of year. Drop a lot of leaves, spots all over the leaves. Just look bad this time of year. Don't overwater and don't let it get too dry. It will probably bounce back in springtime.

Interesting article Simon, thanks for sharing. Going to take another read or 2 to comprehend better. 

Could laying ice under a tree for multiple days on end cool the roots enough to further encourage flowering?

This guy is growing in a pot, and appears to be doing quite well with hand pollination

South Florida (Homestead or the Redlands) makes the most sense. Jakfruit grows well down here, and no international issues to deal with. Shipping should be the least problematic from FL.

You could hire a landscaping company to tend to your trees.

Also, will lay a 3 inch+ layer of pebbles (not limestone) at the bottom of the hole before adding dirt. Hoping this will mitigate the leaching of alkalinity upwards from the limestone, and help hold the liner on the sides in place.

Thanks SoCal2warm. Going to scrape as much of the topsoil as I can around the perimeter of the hole, down to the limestone. Then will line the sides of the hole. Do you think I should also line the newly uncovered limestone on the perimeter of the hole?

Then, will add dirt, mixed with sand and perlite. Lots of peat. Will water, and then add dirt as it settles over the course of weeks and months.

Will add more organic soil to the top, building a mound 18 - 24 inches high. Then, will encompass the mound with rootsaver pots, attached to each other.

Thinking of placing a few (3 -4 ) pvc pipes with holes drilled in them, down into the hole. Then, could add fertilizer or ph enhancements via the pipes to the lower roots and area near the limestone bottom. Can this work well and any advice?

In the springtime, will place the mangosteen tree in the middle of the mound, release the roots from the pot its in, and fortify with dirt and then mulch and water like crazy.  Will set up a misting system, and water daily (probably multiple times daily), until feel comfortable that it has acclimated well.

Not too worried about the transplant. The roots have not shown to be as sensitive and finicky as many report, as I've broken the tap root during previous transplants with no noticeable stress. The key might be in making sure that the entire root system is well watered and healthy, so the plant does not overly rely upon the tap for nutrients.

FFF lemon drop

garcinia acuminata

garcinia aristata.  love this little compact tree!

kuini. Plan on grafting this kuini to an in-ground casturi tree, after it grows and branches out.

borojoa. lost one, down to 2 plants. Dioecious, so not sure what will do unless I'm lucky enough to have a male and female.

Found this Grimal scion shooting sprouts this morning. Grafted 10/26 on an unknown in-ground jabo that's 8 - 9 feet. All of the grafts look promising with some swelling buds, but only noticed new growth on this one.

I've picked up some nice plants off eBay that were not available elsewhere. It is always a gamble, but sometimes is a decent option if you can't find what you are looking for elsewhere. 7_heads has some nice plants, but tends to be overpriced. Picked up a few plants from him over the years that appear to be accurately labeled. Contact him and see if he will make it right.

Yes Kada, a tree on a mound will be a bit more vulnerable. However, wind is a lower concern of mine. Even when we've had tropical storm and hurricane force winds (cat 1) cutting through, everything survived. Some taller trees were bent over, the shorter ones were mostly below the ripsaw of wind. Will do what I can to provide extra protection and support, but will just have to roll the dice.

As long as the neighboring trees are taller, I think it will be fine. It is in a nice little clearing, surrounded by wind breaks in all directions.

Won't let it get too tall, and will trim more if a bad storm is approaching.

This is a fun experiment. While eventual failure is quite possible, having a good time with the project.

Thank you everyone for the thoughtful posts and info! All of this helps a lot.

Thank you Skhan and Dwfl. 

I agree, changing out the soil around the hole would be beneficial. I like the idea of a mound around the area as well.

As for the weather during cold spells, your plan should work well dwfl. I could devise a makeshift green house just by laying plastic over the neighboring plants and mangosteen. It has already tolerated temps in the hi 30's without showing stress, but keeping it warmer would certainly be better. 

I want to put a sprinkler right next to it, to keep moist/humid but also to keep warmer on cold nights.

How long from graft to fruit?

Please let us know about the flavor and other differences. Wondering which varieties taste best in FL.

Thanks SoCal2warm! All of that is very helpful. Going to get the jackhammer back out here and see if we can get down to 3 feet. Plan on building up a mound and elevating the tree about 1 -2 feet

Will line the sides, and make amendments as recommended.

I like the banana tree idea. Have a nice sized mysore in a pot that's begging to go in-ground. It will also be surrounded by jaboticaba, carambola, surinam cherry, and passion vines.

While the tree has been getting some direct sunlight, it is probably 4 hours or less.

One citation showed trees "flourished" with annual rainfall of over 105 inches, and good soil. Going to try to mimic this; create a misty rainforest environment.

Know my chances aren't great in terms of getting it to fruit. It is fun growing, and is the prettiest tree of all the garcinias I have. If it fruits sometime in the future that will be a bonus. Kind of like playing the fruit lottery.

More ideas please!

I'm looking for some ideas on how to proceed with my mangosteen project. Since South FL soil is full of limestone (pic below shows just how bad. It is solid limestone at the bottom of that hole, had to use a jackhammer to get that deep), I was thinking of creating suitable soil, and then placing the plant above the amended soil, on a raised mound secured by rootsaver pots that will be attached to one another.

Just had this hole dug. Thinking I should line it. The hole is roughly 43 inches diameter by 2 feet deep. Calculates to a little over 150 gallons.

How should I line it? Should I leave holes for drainage? Are there any liners with copper in them, and if so, are they safe to use?

Also, any advice on soil composition is appreciated. "deep rich organic soil, especially sandy loam or laterite" is recommended on the site. How might I achieve such soil?

Here is a pic of the tree

I would trim that part off, place the cut end in a cup with moist paper towel, and then place in something like a small butterfly enclosure, and seal it up well. Then, see what hatches out of those eggs. You likely have more of them around, could be beneficial to figure out what they are. 

Mangosteen has been fruited in the pavilion of Fairchild Tropical Botanical Gardens, but I would consider that in the same category as a greenhouse. It is well protected, and could easily be more sheltered more from cold dry winds if need be.

I'm going to give it a good try here south of Miami. Could be wrong, but our alkaline soil worries me more than the cold. My tree did well with our lows last year (high 30's). Landscaper is supposed to dig a big hole tomorrow, and I will plant after laying down a liner and filling with choice soil. Prepared to cover and protect the tree if need be, but the location already constitutes a nice little micro climate. 

You mangosteen looks pretty good Frank. Surprised it's doing so well, being in Cali. Seems a humid and warm protected environment would be needed to eventually get fruit.   

I'm interested in scions as well. Any idea when is the best time to of year to graft?

Jabos like shade and lots of water. Looks like it is getting toasted.

Thanks and Thanks Tang Tonic!

A type of hibiscus sounds about right, as I have planted some different hibiscus seeds in the past. Wondered if they were some kind of beans as well.

Silas Woods sap. Lots of fruit currently growing, one almost ripe. Checking daily.

Passion Vine Alley. 5 vines intermingled. Not even sure which fruit is from which vine.

Curry Tree

Jak seedling, with grafts of pineapple jak, red, and gold excalibur.

Mystery plant, what is this? Not sure if it is a fruit tree or just a hitchhiker. Any ideas?

Seedling from Red Lady. Packed!

Denizen of the garden, devourer of hibiscus

Ponderosa Lemon. This one's only just over a pound

Hello All. Time to share some updates from the garden...

Guanabana, covered in flowers and setting fruit.

Guanabana flowers. Question: My guess is that hand pollination of guanabana is done after the outer flower shell drops, as in the 2nd and 3rd pics below. Is this correct?

Corrongo Caimito

Caimito tree's first fruit. Over a dozen fruits are growing nicely, perhaps much more. Hard to tell how many.

Lemon Drop Mangosteen


Seashore Mangosteen

Luc's Garcinia. She's small, but know's karate!

Purple Mangosteen. Diggin a 3+ feet deep by 4 feet wide hole next week, and will perhaps line the hole and fill with soil that is not alkaline. Going to build a mound on top and support with Root Saver pot panels attached to each other. My hope is to overcome the limestone soil issues that purple mangosteen suffer.  Any critiques, advice, or additional ideas?
