When I was there last everything I purchased was on the ground. I don't know if they have a nematode certified area or not if you are trying to do it legit. I don't know if you will be able to sneak potted plants in on an airplane.

They have people that do this stuff as their job. I would just hire someone down there or contact TREC or other growers to possibly get some contact info. I wish my photos were better organized. I have video of the massive tractor rock plowing a veg field. For tree crops they always rip the cross pattern. I wouldn't dig a 3 x 3 hole unless you are trying to start a field grown bonsai business.

I don't know if that's the best strategy. The roots will pretty quickly grow beyond the 1.5' radius (probably within the first), and the feeder roots generally don't go more than a foot deep anyway. So, you'll end up with several hundred cubic yards of rocks to dispose of (roughly 3/4 yard per hole) with little gain.

The X cutting would be better, as it allows feeder roots space to grow (they can follow the X lines). And you don't gain anything by making the holes that deep. A foot to 18 inches would be plenty. Also, I think your best bet is to get soil depth by bringing in tree trimmer mulch.

When I asked Dr Jonathon Crane about this subject a few years ago, he recommended growing sunn hemp and tilling into the soil.

Thanks everyone for all the valuable suggestions. I am going to rent a back hoe and make 3' * 3' holes .

Federico , I will need your help with finding mulch and some guidance on making holes. I will send a message.


Fruit and Spice has large productive trees on limestone. I doubt they get any attention either.

They are extremely productive in the right climate. Remember trees being totally loaded with fruits. Here in Hawaii they are not nearly as productive.

What do you consider the right climate?

Not to answer for him, but all of the info I find says it prefers a somewhat Mediterranean climate - lots of sun, not too much humidity, not excessive rain, doesn't really like "ultratropical" locations.  Loves California and its native Mexico in particular.  But you can still grow it in places like Florida (although not on limestone)

In general, it seems to rather like being treated like a citrus.  Which I guess makes sense, given that it's in the Rutaceae family.

As you can see from my below photo, one of my Sweetheart Lychee trees refuses to green up. At first I thought it was lack of water, but heavy watering hadnít changed it. Then I thought it may have been nutrient deficient so I fertilized with 8-3-9 with micros. The thing flushed out like crazy but leaves cane out yellow and never changed to dark green. Canít figure it out. My other Lychee trees are all dark, dark green.

Try doing a soil drench using Sequestrene-138 chelated iron.

That's the stuff.

Check you soil pH. Bahahhhahahahahhahaha. JK I forget the expensive chelated iron everyone uses down there. Get some of that.

Most commercial groves in Homestead use a giant trencher. The go through with the spacing they plotted out and then cut across the opposite direction to make a grid pattern. After that they put the busted up limerock pieces back in the trenches and then plant the trees in the middle of the Xs they created. From that point on the trees are almost grown in a hydroponic like condition, normally with conventional fertilizers and ungodly amounts of foliar feeding, especially chelated iron. It really is a strange way to grow.

Was this property previously planted on? It might be trenched out for you already.

There are some organic growers there and some just swap out organic products for the conventional ones and then some actually build up the soil with mulch and compost and whatnot.

If you can spare 6 weeks this summer there is a graduate level course through UF that is amazing. Look up HOS 5555. It is offered every other year on the even numbered years. Dr. Jonathan Crane teaches it. It was such a good experience.

Looks good. Not much of a change except the ph drop which is what Iím assuming you were going for. The difference in suspended solids may be a result of the pH drop as well. What was the time frame from sample to sample?

There was probably 45 minutes between sampling. I thought maybe the increased suspended solids were from the calcium carbonate turning into calcium sulfate.

Carbonates = 0   looks good did you need that low ph to reach 0 Carbonates.Is this injection line or holding tank?

I have a line running directly from the well into two 500 gallon tanks that are plumbed together. I was just guessing the amount of sulfuric acid that I dump into the top lid of the tanks. I would like to keep the pH in the low 6s. This sample was after adding 16 oz to each tank/32 oz total to about 825 gallons of water.

Two samples from the same source before and after I treated with sulfuric acid. I am still trying to learn basic water chemistry so any comments are helpful.

borassus flabellifer that should grow in cali.That is one massive plant though for urban yard

And they are dioecious! I want room for these so bad.

Here you go Simon. My carmen hass is  fully loaded with fruit and still out growing sir prize and lamb hass. Roostock has been buried in the soil.

How deep did you bury the root crown? I have been experimenting with this and having good results. So far I have only done things that root easily like pomegranate, dragonfruit and figs. I am going to try Jackfruit and annonas next. I have been obsessed with this since I read this article a while back.

Eugenia luschnathiana

Vulcanic Brazil ???

They're good here for the simple fact of being native! They are born spontaneously in the forest, both Atlantic Forest and Ana Amazonian Forest

Have you seen these grow in wet/flooded areas?

I have a double root planted out that is growing like crazy. I haven't grafted anything to it yet. I have been waiting to get my trellis installed for a little espalier action. I have some other double root plants in root pruning pots waiting to be grafted. They seem to be doing really well.

Unfortunately that would be illegal to import that ginormous "seed". I got mine in a roundabout way from a somewhat isolated patch at Chapman field. It will be the green type judging by the fronds.

Me too. 9B 34240 I have been watering them heavily.

I like pitomba better than grumi.

What heights has anyone seed the Fiji Dwarfs top out at? I have a young one in ground here that is about to start showing off it's trunk.

Probably iron. Maybe some other micros. They like acid, well watered fertile soil. They also look better when they warm up.

My dozen bit the dust...before Winter! As per the norm...all great to a foot an then dieback. God speed Josh. Chris

This is a very common problem even for people in zone in Hawaii. I think it has to do to a lack of native soil microbes. The roots are so so weak.

Jackfruit is graft compatible.  8)

Or airlayers.  :o :o :o

That never even crossed my mind.

Most chempadek are really delicate and fussy, even here in Hawaii. But there is so much variation that i think one could be found that is as hardy as jackfruit. Just need to keep trying with different types from different sources.

That is the plan Oscar. The initial problem is a very weak root system that leads to damping off. There is likely some sort of microbiome that allow these to thrive early on within their native habitat. I believe I have solved that issue but time will tell. The next step will be finding minimum damage temps next winter.

I too am curious about the Boca Chempedak. I spoke with Richard at Excalibur and he mentioned that with global warming, West Palm area start to get weather like Miami. I don't know how long it would take chempedak to fruit. I'm hoping to grow one, then in 5-8 years, West Palm area would be warm enough to fruit Chempedak, may be even Durian? Wishful thinking, I know.

99.9% sure those aren't Chempedak. Richard Wilson knows his stuff so I am really curious about the story behind this seed.

There was (is?) a fruiting chempedak in the Whitman pavilion at Fairchildís. I saw it fruiting a few years ago.

Thanks. I don't know how I missed that one.
