Tropical Fruit Discussion / Re: When to Pick Wurtz Avocados
« on: October 10, 2018, 04:56:44 PM »
In California I have a 'Wurtz' tree and I try to leave the fruit on the tree as long as possible.  The pictures of the tree and fruit look different than from what kc_moses has posted.  I still have fruit on the tree from the Spring bloom of 2017 plus fruit from the bloom this spring.  The fruit taste much better at the end of the season than the beginning.  I do not know if the fruit would hold well on the trees in Florida.

Seriously?  How does the two year old fruit taste?  Dry at all?

Mine has more than doubled in size in about 6 months. About 6í tall now, no fruit yet. It does appear a bit sunburned tho.

Roof rats love key limes.   My mother had to cut her tree down. We were absolutely inundated with roof rats in my townhouse community in Scottsdale. I even saw them crossing on top of the red lights to go from community to community.  One winter, I killed over 100 with rat traps and peanut butter.
Finally, this year it is under control.  The remedy?  Feral cats moved in, ate them all and left.  From my experience, if you have roof rats, that is the only way to get rid of them!!
Empirical and video evidence indicate shows that cats rarely wil attack an adult rat.  An adult rat is too aggressive and will put up a fight the cat would rather avoid.  There are videos that show rats and cats ignoring each other as they both go thru trash looking for food and of rats running past a cat as if the cat was not there.  Cats will decimate the bird, lizard, frog, vole and mouse populations though.
 
What rats are to fruit growers cats are to the environment.

Well you need to show that empirical evidence to my cat. She was formerly feral and is unaware of this evidence apparently.

I do not believe that they will bother citrus.  Could be wrong.

Squirrels do get into my citrus late in the season. They tunnel into the fruit and eat the seeds oddly enough, leaving the rest of the fruit behind.

 I think I see either an egg sac or an insect on the top right leaf. You might want to give the plants a dose of  Imidacloprid. I always do now to make sure a plant isnít attacked while young and vulnerabile.

Thanks to both of you for the suggestions. With 5 banana stands, I have some work to do.

I agree with the thinning, itís more work than I wanted to do, but it needs to be done. I also need to move the dwarfs further away from the tall plants.

BTW, one of my cocoa trees has about half dozen cocoa pods on it and itís still blooming

You do realize that - generally speaking - traps are NOT for control, just for monitoring the population?  Traps generally don't do a ton for control, but do make you feel better.  Kind of like how roach sprays don't do much for population control, but make you feel better.  If you do use traps, place them AWAY from your trees, not on them.

Tropical Fruit Discussion / Sigatoka treatments??
« on: October 03, 2018, 06:15:26 PM »
My bananas are getting devastated by what I believe is sigatoka fungus.  Once the plant fruits, it of course stops making leaves, then the leaves are dying before the bananas can mature. 

Anyone had good results with a fungicide?  I'd prefer no harsh chemicals of course. 

Copper fungicides?

I'm not opposed to replanting with a more resistant plant.  So far, my apple bananas seem to be doing well.

Thanks.

 First, you should have cut the stalk below the bananas a long time ago. Some of the plantís energy has been going to developing that stalk and the worthless flowers it continues to put out.  Once the bananas turn to male, cut it off. 

The bananas are very close, but they appear to need a little bit more time. The sharp corners need to round out in the fruit needs to plump up a bit. Some of the bananas on the top of the stalk look like they may be ready to harvest.

Bottom line is if you pick the bananas too early itís a total loss. If you pick them a little bit too late itís no big deal as the bananas still develop excellent flavor. The way that I found to never pick them too early is wait until one of the bananas just barely starts to turn yellow. Then it is without question safe to cut the entire rack off the plant.

That fruit looks bad. I wouldnít eat it. Better send it to me for testing.

Tropical Fruit Discussion / Re: pineapple top planting
« on: September 25, 2018, 06:46:04 PM »
The Pineapple Crown can still be grown even if the center leaves are pulled out it won't produce a pineapple but it will grow suckers that you can regrow from that will produce pineapples but it will take longer doing it this way.....for it to work the crown still needs to be a great shape and has no signs of rot

THAT is what I needed to know! THANKS!!!

I do not want to waste the space on sucker donors. I'll plant viable store tops and suckers / slips from existing plants from now on.

I disagree with the bold statement. To be honest I canít ever remember planting one that didnít root and Iíve done it both ways.

One thing I do different is I pluck several of the smaller leaves from the very bottom. This exposes several nodes that end up turning into roots pretty quickly. I try to expose about 1/2 inch of the core at the very bottom.

Tropical Fruit Discussion / Re: I am taking out my citrus trees in Miami.
« on: September 25, 2018, 08:48:46 AM »
If you think it hurts to pull a Mineola try what I did.....I had to pull 200 citrus because of Greening in Kendall after having raised them for 14 years. I was the greatest citrus grower anywhere. I sprayed my trees every 2 weeks and yet all but 2 got the disease. Yes the Mineola needed a pollinator. Now I have 250 mango avocado and lychee. And 1 Temple thatís got Greening and this will be itís last season then Iíll pull it out after 17 years. And 2 Yosemite Gold hybrids from California about 15 years old that are somehow still beautiful and green and healthy. If you saw my present trees youíd know how perfect I took care of my citrus. IN MY OPINION THE SALE OF CITRUS TREES TO THE PUBLIC SHOULD BE AGAINST THE LAW BECAUSE THEY ALL GET GREENING WITHIN 5 YEARS. SO WHY TRICK THE UNKNOWING PUBLIC INTO BUYING TREES THAT ARE DESTINED FOR A QUICK DEATH. THE ONLY WAY TO GROW CITRUS NOW IS UNDER NETTING.

Not true. https://www.ncbi.nlm.nih.gov/pubmed/21061971

« on: September 23, 2018, 08:14:40 PM »
I've used plastic pvc pipe before - two long poles and some corner pieces to make a cross bar.
How would you adjust the height?  I have numerous varieties of differing heights.

Tropical Fruit Discussion / Re: Vegetative propagation from fruit tissue?
« on: September 23, 2018, 08:13:35 PM »

But could the stem of an apple or pear be induced to root? What if it had a leaf on it?
Yes and no, in a traditional propagation system using rooting hormones. The stem need to have enough energy to grow roots which it's hardly possible with a stem form store. Stores also spray with fungicides and preservatives which inhibit growth.. From a leaf no.


What type of tissue is typically used for tissue culture propagation?
The best tissue and simplest it's meristem which contains undifferentiated cells.
Virtually all parts of the plant can be used to cloning via callus induction. Even from a single viable cell, but this requires expensive equipment and special techniques. Each plant has a different need and requires chemicals to be used.

For instance it's possible to take a lime from store and grow callus form it, then shoots and finally root the shoots. Or use the shoots and micrograft them to a rootstock.

That was more or less what I was thinking.  I would think that while technically possible, it's pretty improbable and would have to be done under perfect conditions to even have a chance. 

I took the tour at Epcot and got to peek into the lab like I said above, the conditions there are as sterile as any medical lab, and they have a lot of specialized equipment.  If you get the chance, I highly recommend taking the tour, I was at Orlando of course.

Very interesting! Amazon has this kit for the reasonable price of $64, but there are zero reviews.

Very very interesting. So this can be done with lime skin? Or which part of a purchased lime? So would this be possible from a mango skin or piece of stem?


Who here has experience doing tissue culture? Thanks!


I did some tissue culture work as part of my Masters degree project (selected loblolly pine cultivars).  I'm surprised to see a kit offered for general use, as what struck me the most about tissue culture production is the absolute need for a sterile environment. It is easiest to keep things sterile in a laboratory, where you can work under dust removing hoods and keep an alcohol flame burning to sterilize your cutting tools.  Your agar medium starts out sterile but it's so easy to introduce unwanted organisms to it as you transfer your plant tissues.  I had issues with keeping sterile even in a lab - I can't imagine trying to do it at my house.  That said, I must say I am intrigued by the kit for sale and might even buy one!  :-)

Please do, it'd be nice to get one of the people on here that know what they're doing to test it out.  I peaked into the lab at Epcot once, it looks an awful lot like the equipment they had.

I used the 2x2s and drill a hole larger than screw in one and screw into the 2nd one to make a X pattern and they can be spread out.  You need to get the crotch of the supports the right height.

Took me a while to figure this one out.  So you use a wood screw?  I assume you leave it snug, but not tight?

My thought with using lashings was that it would be very easy and quick to move lashings in case I'm going from a 10' plant to a 6' plant.  But the screw idea has merit for sure. 

Does anyone use pipe insulation or some padding on the brace?

Tropical Fruit Discussion / Cheap banana brace ideas?
« on: September 23, 2018, 03:43:57 PM »
Well, a year after Irma wiped out all of my mature banana plants, it suddenly seems that ALL of my remaining plants are getting ready to bare fruit.  I suddenly find myself in need of several banana braces and don't want to spend a fortune.

Anyone have any good ideas for cheap, effective banana braces?

One idea I had was to get 2 2X2's and tie them together with rope in an X pattern, this would be easy to adjust and pretty cheap.

Any other ideas appreciated!

You only have to apply it once a year. I would recommend doing it immediately after bloom. Reason is we donít want honeybees to pick up any of the toxins. I can post some before and after pictures if you like. My growth from the spring before treatment is devastated. But after treatment all of my new growth looks excellent and Iím very encouraged.

Donít give up. After years of frustration I seem to have finally found the answer to growing good citrus these days with all of the imported pests. Lowes is the best place to buy it they have it in stock and it is also the cheapest place to buy it. https://www.lowes.com/pd/BAYER-ADVANCED-32-fl-oz-Fruit-Citrus-and-Vegetable-Insect-Control/3170999?cm_mmc=SCE_PLA-_-LawnGarden-_-OutdoorPesticide-_-3170999:BAYER_ADVANCED&CAWELAID=&kpid=3170999&CAGPSPN=pla&store_code=613&k_clickID=cb6ffbc2-8cd3-4fb0-a90e-725d465d27ba&gclid=EAIaIQobChMI36Wf1cLR3QIVm0oNCh3ROgZDEAQYASABEgL5IPD_BwE

Simply plant without cleaning them.  We do this routinely on a large scale to have rootstock for grafting 
Peter

Thank you. Iíll take your word for that. So I take it cacao is not true to seed?

« on: September 20, 2018, 10:39:48 PM »
Wow 70 fruit is nice! So you only spray once with sulfer as soon as it blooms and thatís it?  Do you spray if there is no signs of PM as well as a preventative? How about in the off-season? Thanks bud!

Every time I've seen it or sooty mildew there is an aphid infestation.  I'm sure it's not 100%, but it's pretty consistent.  Look it up.

I just leave on the bench for a few hours until the gooey part dries slightly then scratch the whole membrane off around the seed. You need long nails to do 😄

I might try that, I was going the other direction, soaking them to try and loosen it up.   I know if the seed dries out, it may not sprout.

Why do you want to clean them?
Some people suck the pulp off and that will clean them somewhat.
Cacao is normally fermented without water to process.
To plant the seeds they donít need to be cleaned.
Peter

I edited it, I want to sprout and plant them.
