Beautiful fruit Mark!

Was it ripe at that stage of color? How did you determine the best point to cut it open? By smell?

I am growing mango in a container for the first time and a Pickering at that. Have a couple of fruit hanging. I am quite surprised by the fruit size growing in a container.

It was totally hidden.  I only found it poking around in the canopy.   I always let my mangos ripen on the tree until they color up.  Will try it today.

Highly recommend a root pruning pot. You'll get much more production in a smaller pot.

I agree with Mark in regards to spreader stickers but I like the added benefits of extenders as well. I recently started using Nufilm P, they were sold out of Nufilm 17. Once activated by UV, it is ran fast. The Nufilm 17 is a better extender and the Nufilm P is better if you are harvesting within a couple weeks because it doesn’t last as long.

These new types of spreader, sticker extenders significantly increases the efficacy of foliar sprays and will save you time and money in the long run. In areas with frequent rainfall, it will enable you to spray once and not have to worry about spraying again after rains.


Interesting and it's made by Red River.  I buy their NIS.

Got mealybugs? Me too! Found this Pickering mango tucked away in the canopy covered with them. This delicious "condo" mango has a background of coconut, rind smells like it it too.  Been fighting these bastards for years.  They really like annonas and mangos.  Control has to be in the crawler stage.  Hort. oil with bifenthrin. 

I religiously add a non ionic surfactant to all my sprays, period.  If not you're wasting your time.

Best systemic OMRI approved coppers are Phyton 35 and Magnabon CX2005.  Magnabon is also good for fire blight control. 2 tsp./ gallon, 1 tsp. of a surfactant.  Becomes rain fast once dry.

Just wanted to share pics of my yellow undatus plant sold as "giant hawaii gold".

This is easily the fastest growing DF plant I've got out of around 30types.

It's starting to flower for the first time. 

Nice group!

I tried to follow the link, but it ways only visible to members ... can you help me get there, would love to see video of this 'cool house' Mark

P J, the Dirt Diva

Sorry, gave you a link to a SoCal avocado group.  Also there's a ton of great tropical gardening groups on Facebook. I belong to a couple in Hawaii, am a member of Southern California Backyard Avocado Growers, Mango Tree Growers Of America, greenhouse growers, etc. 

I tried to post a MP4 video here but no luck.  I just show a scan of the greenhouse and the fogger.  Fog is hard to see due to the white background so you're not missing much.

Would you post a picture of the nozzle, and its location?

Read the thread.

Supposed to be smooth.  The tissue culture plants grow like crap too so compost those.  I'll send you a couple good pups later in summer if you want the WJ like in my pic

Hell ya, will reimburse ya.  I think I'm going to dump all of them.


Thanks Brad. I got Sugarloaf from a friend, pups.  White Jade came from Wellsprings Gardens.  Looks like I just got dogs.  One of them fruited in winter.  Gold color, taste was awful.

Yeah, leaves are serrated.  So they're supposed to be smooth?

My experience is similar to yours.  Mine do fruit but the fruit stay small and the plant throws all kinds of pups.
Were I in the pup selling business, it will the the goose that laid the golden egg.
But I want to eat some pineapples.

I get some pretty big ones off twistees.  So I have to core, big deal.  They are sweet, smell rich, just great.

Here's a Sugar Loaf, big mess of pups.  Notice the 2 little pups shooting off the fruit too!  I think I'll stick to store bought DelMonte twistees.  They put off excellent fruit a year or so ahead of the white ones. 

Only way to go -->

Kinda expensive. I got a 25# shipped for $46 from a TX distributor.   Excellent sunburn protection, easy peasy to apply, good pesticide for tough bastards like the grey leaf footed bug that ruins maters, peaches, etc.

Yeah, it's a fogger.  Check out the video.

Even with very soft water pads are a PITA.  They have to be cleaned, replaced, sealed during winter.  Moving parts have to be replaced - pump, float valve, etc.  This fogger is very simple in its design.  The only thing that would eventually have to be replaced is the motor.

Hey Mark,

Any reason you went with misters instead of an evaporative wall cooling system?

This not a misting system. 

Wall evap. is a PITA regarding maintenance unless I use R/O or rainwater. Gotta seal it up during the winter too.   Trust me, I have selected the best cooling system available regarding reliability, no maintenance, rainwater sustainable and high efficiency.

Beautiful pineapple Mark, we had a big White Jade a week ago was sweet an delicious right through the core all totally edible except  skin of course ;) I had it in squat 7-gal pot too!

Wow, how nice!  I don't know what I'm doing wrong.  Guess I need to get it out of those small pots.  BTW the fruit also has a lot of plant pups on it.  Need to get a picture......

Awesome, Mark!
I am still cooling with tap water misters, but I DID just get a descaler, so I am hoping that helps.


Howdy Carolyn, take a look at TAC conditioning.

Lots of systems out there.


I use a 7 gallon on the white jades and the plant gets giant.  They usually make about 4 or 5 pups at the base and another 4 or 5 along the stem and under the fruit. 

The one in the pic is a smaller commercial type plant in 5gal.


I like the Del Monte Golds better.  Got 2 "twistees" from Costa Rica started. Fruit was unreal.

Nice cooler Mark.  Jealous of the rain tank and rain during summer.  We get zero rain the entire warm season.  Complete opposite of what we want here.

We're like you, come about June the tap is turned off.  We get a high dome of pressure dead center over central Texas and it doesn't move until early Sept. unless we're lucky.

That sounds small, interesting... Could the proliferation of pups have to do with the pot size?

Nice Mark!
My system is pretty low tech..
The plastic sheeting on the south facing wall of my greenhouse was held down with battens and screws.
I remove the screws and battens... roll up the plastic... and reverse the whole process when cold weather returns.

Kevin Jones

I wish I could do that but my polycarbonate is held in with self tapping screws.   Many folks do hoop houses here where it's covered in poly during the winter and shade cloth in the summer.  They also cuss a lot when they have to cover in a wind.  :)  One hail storm and it's toast too.

Nice setup for cooling.
Id be carefull with that pipe from the barrel that passes near the GH in winter.It could freeze and crack if you get low winter temperatures.

Thanks.   I have ball valves at the tanks plus a slip joint in the middle. All you do is unscrew the ends and it drains or comes apart.

BTW, got some flex PVC pipe from a pool/spa supply company.  PVC fittings glue up to it and I finally get some flexibility I need rather than have to measure and cut to tolerances within a mm.  You guys that work with PVC, bends, turns, and what not don't know what you're missing.  This is 1" ID.

Nice pineapple! What size pot do they fruit in?

3 gallon for me.  Am really disappointed in Sugar Loaf and White Jade.  One is fruiting now after about 2 years and all they seem to want to do is throw pups.  Never seen so many.

Thanks guys.  Teed off to a garden hose bib so I can water my faves. 

I have a feeling that when our normal summer RH drops below 40% this thing will be the bomb.

You can also fog the house with pesticides and fungicides.

After 2 years of research, "what ifs", and 3 weeks of messing with tank installation, fittings, pipe and climbing ladders IT'S DONE! This new greenhouse centrifugal, adjustable Aquafogger, pump, and 2,800 gal. rain water collection system is "too cool".

Fairly quiet, output adjustable from 1 - 15 gph.  Unlike nozzles and high pressure pump this is supposed to be the most reliable and easy to hang system on the market.

If anyone does Facebook my page is public and has some video.

Nice Mark, your reeds are a little earlier than here.  Extra heat from the GH.

I guess.  Another fell off.
