Tropical Fruit Discussion / Re: Dripping with mangoes
« on: June 05, 2016, 01:47:28 PM »

Five year old Mahachanok about a week ago. I have already thinned the fruit some. The other side of the tree has more mangos than pictured here.

DO they sell grafted trees, what did you get where you happy with what you got?
Yes. I have never purchased from them but their nursery plants always look healthy.

I though we weren't supposed to fertilize at all during fruiting...?
Not much, but the trees do need trace elements and some potassium for the fruit. No nitrogen needed since the plants conserve it. Any extra nitrogen tends to make the trees vegetatively flush with adverse consequences for the harvest.

I asked Guanabanus (Har) "What do you fertilize mangos with at this time of year?" and he replied:
0-3-16, or 0-0-16, with 4% Magnesium and a full complement of micronutrients;  also give them Gypsum (Calcium Sulfate, at at least 1/5 the volume of the mixed fertilizer applied, every time.
My soil is mulched but otherwise dry, sandy and poor. I'm not sure about the pH. I am using some Harrell's 0-0-5 with micronutrients now.

This is how the tree looked this morning before i started removing the banana.
I added a thick mulch of avocado-mango leaves all around the tree to keep the soil moist even in this extremely hot weather.
I'm undecided wether removing or not the guava tree that is at a 8 feet distance, its visible in the right back of the picture.....

The guava should be OK although 8 feet will be crowded for the mature trees. The bananas can be transplanted elsewhere so they don't send up suckers all around the mango. Eventually most bananas will spread out and form large clumps where nothing else survives either from shading out or starvation.
Good luck.

I agree that the tree looks healthy and I would certainly get rid of the banana plants next to it. They spread and will be a problem in the future.

Pine Island is where you find many fruit orchards and decent nurseries. That ought to tell you something. There is only one mainland access road however.

I have always bought 3 gallon plants if possible. I usually cut them back at planting and shape them as they grow out. They are easier to transport and plant and are easier on the wallet too.

Mahachanok with Mallika to the right.

Angie, cut down to 15 inches last year at planting

Mahachanok, cut down to 15-18 inches 5 years ago

There is plenty of ground clearance under the MC without the additional 2 feet of tree trunk. I have no disease problems either.

Here are pictures of cut mango stumps in a neighborhood yard. The chopped stumps are flushing out OK. All the trees were the same size before cutting.
I had planned on topping just below the first node above the graft union.
Don't do this! If you cut below the first node above the graft of the LZ scion, the stock will be all that is left to regrow.

Unchopped Mangos in the same yard

I drove to Orlando and brought the MC back in its pot. Also, Mickey's 3 gallon plants are noticeably larger than a 3 gallon elsewhere. He will (or used to) send you a picture of the plant. Contact him and ask questions.

Anyone know of a reputable mail order source for LZ?  PIN does not have LZ & will not stock MC until May FWIW.
Plantogram ships both MC and LZ but it will cost more than PIN. I purchased my Mahachanok from POG.

I thought I would try something new. I decided to start fertilizing my Maha. I started several weeks ago when I first saw the first signs of swelling hoping to halt the flowers and let it put out new growths instead. Coincidence or not they are now bursting with  new growths, no blooms that I can find. Almost every branch has 1-4 new shoots growing.
I did the early season fertilization with my new mangos for the same reason after they were planted in 2011. There were some flowers but mostly vegetative growth was produced. The trees were pruned at planting too.

Tropical Fruit Discussion / Trees and Wind Resistance

Of interest to those of us that live in storm prone areas. Nothing is said about root strength.
42 meters/sec = 93.95 miles/hour

I have found WU to be very inconsistent with their information and specific local reporting stations.  With them now owned by IBM, you might think the backing is there, I am not sure its a good thing.
I agree 100%. I don't use WU at all.
I asked a local TV meteorologist this question years ago and he replied with a NOAA site.

Citrus General Discussion / Re: GMO Trees Or Perhaps Only GMO Rootstocks
« on: January 12, 2016, 07:16:39 AM »
I'm surprised they haven't used genetics from an existing citrus species, rather than making a transgenic organism.
One of the genes being tried is from a close citrus relative but that would still be transgenic. I don't remember which species it comes from. Another trial uses a gene from spinach.
Trying to kill two birds with one stone, these trees are being evaluated for canker resistance too. From what I've heard, this has also been achieved.

How bad is it for growers in FL?
Pretty bad. There are many abandoned groves in central and south Florida which are not making HLB control any easier. Some forest service equipment has been brought in from Montana to clear entire groves. These machines cut trees at ground level and toss them into chippers. I don't know if any of the groves are being replanted or not.
I (and others) have noticed that there are many mature volunteer citrus trees growing wild in forests that show no signs of greening while nearby groves are infected. Does grafting increase citrus susceptibility to greening?
This is a link to Lake Alfred:

I just returned from a TBRFC meeting and the presentation was about promising new citrus varieties. Their HBL resistance is generally better than current citrus. Much recent research at UF has been on rootstock resistance and field trials are underway. Seeds for these resistant stocks are in short supply so it may be a while before plants are widely available. Even with this advance, in FL citrus will need some special care (fertilizing) to do well. Citrus is no longer 'plant and forget' like it was back in the day. Some varieties are naturally more HBL tolerant than others and these grafted onto a tougher stock will be within the effort level of the backyard gardener.
I asked about the ongoing GMO citrus trials and the results are looking very good with some totally resistant trees (PCR negative) thriving in greening infested locales. FDA and USDA will have to approve any release of these. That may take a long, long time.
The UF Lake Alfred website contains information about the rootstocks.

Any other 0-0-50 sources in Broward? And I mean the granular kind of potassium sulfate in 50lb bags. Not the quick dissolving powdery kind for irrigation systems
Get in touch with Harrell's (Lakeland, FL) and find one of their vendors near you. They can order granular potassium sulfate for about $30-35 per bag. I don't know if there is a minimum order size.

Anyone have any experience/advice in general? Anything that leaps to mind as far as pitfalls, etc?
Here is a Penn State study on plastic mulches that may answer some of your questions. Good luck...

One or two fruit should be OK with the plant sizes you listed. I had full size fruit on NDM and Pickering after two years in the ground. How long have the trees been planted?

Use phosphoric acid. Its second pKa is 7.198 which is close to your target pH of <6.5 - right where you want to be.
With a 150 gallon tank, you can learn how to make a phosphate buffer solution rather than paying big bucks for small quantities at a store. This will involve buying some potassium phosphate too. This should get you started -
