Tropical Fruit Discussion / Re: Help: black scale on jaboticaba
« on: November 27, 2023, 11:51:51 AM »
If these are outdoor then all you usually have to do is stop the ants from farming them with a barrier like tanglefoot at the base of tree (not ideal to put the tanglefoot right on the tree due to asthetics). Provided that you have a healthy ecosystem then wasps, ladybugs, lacewings and parasitic wasps will take care of them. Try to encourage local predatory bugs by planting native flowers and avoiding systemic insecticides.

All my scales and meat bugs get stripped of my infested plants if I take them out in the spring.

K, Iíve tried a couple of different things to fix the clogging. The hose end sprayer I have now does have a little filter on the intake, but itís surface area isnít enough. I tried prefiltering and that was too slow. Recently with my leachate containers I have a spigot about 2 inches from the bottom and I try not to disturb it so the solids settle to the bottom. That seems to work pretty well right now.

Carolyn, I usually just have a cold water line for watering. The water can get really cold in January (40F), but by then I am not having to water much and then would be just using the water from my dehumidifiers. The Venturi would be for the summer, Iíve realized over time that my containerized plants are both unwatered and underfed during the summer months. I think for optimum growth they need daily fertigation.

This fall Iíve been fertigating weekly with a cheap hose end sprayer whose maximum concentration is still more dilute than I like (tap water 110ppm, with the fertigation 200ppm max). But the growth has been remarkable even with it this dilute.

In the past I only used solid organics as a top dressing twice a year. A alfalfa/verimcompost in January (the alfalfa I supposed to break down over a year), and then a mix of composed fruit peels and vermicompost (potassium rich) in may. I was treating them like in growing plants cause there isnít much info on containerized culture. All the composting people say the liquid byproducts of compost/vermicompost/bolashi should be thrown away.

The big issue with the solid organics was the fruit flies and fungus gnats, it was crazy. There are basically no flies anymore with the dilute fertigation cause all the chemical energy has been sucked out from the decomposition. The secondary benefit is that the plants are even more happy with the regular dilute feed. I think I should have been thinking about things as a hydroponic setup.

I get about 20 gallons a week of deionized water from a dessicant and compressor dehumidifier. The water is warm and usually plentiful enough when the tap water is just above freezing. Electricity is relatively cheap here (vast hydroelectric reserves).

I will let everyone know how it works out.

I actually just found a website that sells a bunch of different Venturi style injectors. They even have pressure and flow charts on their website. Assuming my hose is 50psi and by flow is about 12gallon/minute the rkv175 would give me a dilution of about 15:1. Itís only 40bucks so Iíll probably give it a try.

Has anyone used these before from this company?

Tropical Fruit Discussion / Re: Are there dwarf loquats
« on: November 22, 2023, 08:35:13 AM »
Andrew, I grew loquat seedlings for 6 years in a 20 gallon pot before it finally flowered. I bought 2 1 gallon cultivars and grew them in a 2 gallon pot for 1 year before they flowered (forced flowering in spring) and them potted them up to a 10 gallon. This is the plant now 18 months after purchase.

Hey all, so Iíve been fertigating (water and dilute fertillizer) my containerized plants with home made organic liquid fertillizer from a worm farm and bokashi composter. Itís working well and everything is super healthy. Iíve been trying to track down a hose end sprayer that had a dilution factor of 10. Does anyone have any suggestions.

Mike, very interesting. What happens with the seeds in the female only plants? Also (best guess) how frequently will they be self fruitful?

I had my sugar apple grow fast and fruit (only 2-3 per year) within 2 years but it as looked progressively worse for the past 3.

9
Not sure if itís just me (all plants in containers) but after a couple of years my sugar apple has started to look terrible. If you are going to be able to protect them in the winter why not a soursop, they grow like crazy.

Nate, I just thinks itís a cool concept, but you are right not suitable as building material as of yet. We need more people doing research in advanced materials for greenhouse design so that everyone can grow tropical fruit.

Another neat idea is to use phase change materials (pcmís). Water barrels work like this, if the water were to freeze they release a huge amount of energy (100x what you can get from a concrete floor) they also use special salt solutions and waxes. You can really nerd out on this stuff, but you start to sound kinda weirdÖ and eventually people donít want to talk to you anymore, so then you just talk to your plants. Iíll shut up now.

14 years!!! Iíve had mine for 5. 2Ē trunk diameter. It flowered a bunch last 2 years, no fruit set despite me obsessively collecting pollen. Perhaps I should use this for kindling like my jackfruit?

Tropical Fruit Discussion / Soursop fruiting in container?

Has anyone gotten soursop to yield fruit in a container? If so what size of plant/pot was required.

It sounds like it seems pointless to try and fruit jackfruit in a container. Itís too bad, itís such a nice looking tree. I guess itís next on the chopping block next time I need space.

16
Nick, how long have u had that tree? Any flowers yet?

17
I am no expert in either, but I was able to get three starfruit off a plant that was completely ignored in a7 gallon container this summer. I am now taking better care of it. It is currently reflowing and setting more fruit. Iíll let you know how many set.

 As for jackfruit, I was asking the same question a couple of days ago. I searched through all the threads and seems it needs a large container (25gallon) with considerable trunk girth (4Ē) before it is weíll established enough to fruit in a pot.

Tropical Fruit Discussion / Are my Loquats ripe?
« on: November 05, 2023, 11:51:29 AM »
So Iíve got my first bunch of loquats which are in the process of ripening. Iíve never seen or eaten a loquat fruit before. These fruits are starting to get soft, but they donít seem orange enough and there is still a touch of green. Do I leave them on for longer? Thanks Iím advance for your knowledge.

Tropical Fruit Discussion / Re: First Nam Wah bananas for 2023
« on: November 05, 2023, 12:15:19 AM »
How tall are your plants and how many bananas did it produce? I had a ďdwarfĒ namwa a couple of years ago and it fruited but barely fit in my 14í greenhouse (it was in a pot). Also I got 57 off of it in a 35 gallon pot, curious what they would max out at.

21
Plantinyum,
Thanks for posting your pics. Iím always curious about the different setups people come up with. Do u have strategic ďmicroclimatesĒ for specific plants? Specifically, I was wondering about what is next to the heater do u need spider mite resistant plants due to the heat and low humidity (not sure low much the rads dry out the air).

This guy better watch it or heís going to be labelled as a witch and be burned on a tree stake.

John, there have been studies that rocks in the bottom donít help increase drainage, they just waste root space. For my pots that sit on the ground I actually drill large holes 1Ē on the side at the bottom so the holes donít get plugged from The weight of the pot. The drainage is good but some soil will spill out and make a mess. To stop that I put a small handful of shredded cedar mulch in front of the holes ( 2 holes for <10gallon, 4 for >10 gallon) to act like a course filter to stop the soil falling out. If ceramic pot with large bottom hole they sit on ďfeetĒ or sit on another pot full of soil.

24
Plantinyum, are your radiators on the ground? Do you have space for a ceiling mounted heater? Iíve got infrared heaters mounted on the North wall that work very well for my greenhouse design.  They can be a bit pricey to buy/run.

25
Plantinyum,
Any issues witch phytotoxicity with that regiment? Iím always worried that sprays will damage new growth or flower buds. I heard star fruit doesnít handle oil sprays well. Also how much is neem oil, vs an ultra fine hort oil. The canola oil product with pyrethrine was 30usd per litre, which is ridiculous. I need to get over my ďecoĒ obsession and use an ultra fine mineral oil compound which is half the price.
