I live in zone 3, I actually grow them year round in my heated greenhouse zone 11. I grow yellow wonder and they are delicious. Very small i can usually get about 3berries per week per plant all
Winter long. I have them next to a window so they may dip down to 8-9c in January. I grow them in 2 gallon buckets and they produce well until the heat of the summer, my greenhouse maxes out at 32-33c. I will usually divide the plants in summer and plant them all Outside except for a couple. I grew them from seed and chilled them in the fridge for a month.

Regarding the fertilizers, yeah itís still a bit of an experiment/stubbornness on my part. For some of my older trees in big pots with lots of critters (worms millipedes)  it works not too bad provided the soil is warm during the winter. Iím trying a bunch of different things, green manure, bokashi/vermileachates, and vermicomposts. Once Iíve got the logistics/science all figured out Iím gonna try organic/synthetic and compare yields.

I was asking the question as it relates to grower personal preference due the fact that I have limited space and if one is significantly better than the other Iíd like the extra room.

Hey everyone, Iíve been struggling for a while to grow container tangerines in my (tiny)greenhouse. I love tangelos, and have been growing a ďMinneloaĒ for about 5 years. Despite it being very healthy, It struggles to hold fruit, and the fruit that it has produced has been less than impressive. I also picked up a 4í sugarbelle 18 mo ago, and am currently (almost finished) resolving a chlorosis problem that has probably arisen as it transitioned from synthetic to organic fertilizers over the past year.

For those of you with greener thumbs or better climates, which plant do you prefer in terms of health productivity and taste? We donít have HLB in canada so that isnít a factor. Also if a citrus has been unproductive but looks healthy, do you think is worthwhile to graft onto it?

Thanks Al,



I like the red lime (kumquat rangpur hybrid) mostly because it is unique and very productive. Up here itís hard to buy interesting citrus. The red is cool cause it has a unique flavour if you are used to standard citrus (lemon lime orange) and u can eat the peel. Itís also very everbearing and productive, just over our long dark cold winter and it already has 7 fully ripe and 16 fully formed fruits on. 4ft tree in a 25 gallon pot. They are also a good size, like a good Persian lime. Onlyissue is the seeds, I cut them in half and flick  the seeds out before a crush it in a cocktail.

The desiccant dehumidifiers arenít nearly as powerful as the compressor ones we are used to here.I was planning on deflecting it with a a plant and it just so happens I have a dragon fruit that may work well.

I guess I should also ask which plants people think are MOST SENSITIVE to warm dry air during the winter. Donít La NiŮa weather patterns cause warm dry winter air in California?

Aip, thanks for the plant suggestions. Humidification at night doesnít work in the winter cause even though the greenhouse frame thermally broken, water condenses on the frame at 0c, and starts to ice up on the frame at -15c. At -40c outside even if the room humidified the moisture wonít stay in the air and just freezes to the frame. I use the dehumidifier for when the sun is setting to keep it under 65%, as at that time the rh can temporarily shoot  above 80% as the inside temp drop from 28c  before it crashes down to 40% by the morning when the air temp is 17c.

How were the cocktails ?
Any different to using regular Lemon or Lime ?
I hear it has flavour elements of both.
Sounds interesting.

It was ok, I like citrus with sparkling water and a nice blanco tequila. Usually in a 1:1 of juice to tequila. The flavour was ok, the half ounce of tequila was the most dissapointing. I much prefer a red or persian lime flavour wise, also I can usually get 2 oz of juice per fruit.

When people say 8 feet tall they donít include the leaves do they?

Hey everyone, my 4 season cold climate greenhouse uses a dessicant dehumidifier in the winter to both minimize condensation and also provide some heat for when itís really cold (-40). The issue is the dry air it produces isnít great f for some plants. My meyer lemon dropped almost all the leaves that were in the area where the dehumidifier blows.

Does anyone have suggestions for plants that could handle dry warm air in the winter?

Hey everyone, I have limited space in my greenhouse and just got my first fruit of my baboon lemon. It was a nice size and looked good and was looking forward to making a couple of cocktails for myself and a friend, but was very embarrassed with the amount of juice I got from it, less than a tablespoon.

What do I do? Will it get better as the tree ages, or did it need more water etc. Or do I get rid of it in an attempt to save my reputation as a tropical cocktail connoisseur?

Here is whatís left after I crushed it trying to salvage my cocktail.

Tropical Fruit Buy, Sell & Trade / Anybody trading/selling in Canada?
« on: March 12, 2023, 04:32:05 PM »
Due to some import bans some of the inconsistencies with bringing plant material across from the U.S. I was wondering if anybody sells/trades plants and scions in Canada?

Which ones have you found to be the best for eating out of hand?

Also have you tried groundcherries, I havenít tasted them
Yet. I tried some last summer and they got hammered by spider mites. I tried them again this winter (not planned). They seem to also be aphid magnets, however they are still flowering and fruiting like crazy despite being infested. They were a spontaneous volunteer in one of my banker plant systems so Iím leaving the aphids be.

Iím not sure if mine is a Sabara but I just got my first ones this year they are amazing. I actually thought the skin was good too. Enjoy.

How do your citrus do at those temps? Iím worried there isnít enough microbial activity to keep up nitrate production when my soils are under 15c.

What temp are u currently running it at? Iím contemplating dropping mine a bit (5c) so I can get more chill hours for nectarines but Iím worried it gonna mess up all my other stuff (I use organic fertilizers so nitrate production may get messed up). I currently have mine between 16-19c at the warmest areas, goes down to 8 deg on the coldest night by the windows.

So sad. I had a dwarf cavendish in a container that rotted as well just as it was flowering. I was able to successfully fruit a dwarf namwah with our any difficulty before the cavendish died. The only difference with the two was one was near a circulation fan in a warmer diet part of my greenhouse while the other was closer to a window.

Brian, how big are these trees? As a fellow container gardener Iím curious about people experience/ opinions about what is the upper limit of practicality and productivity? Iím still figuring things out, but I used to have a bunch of trees in 35 gallon pots but Iíve been downsizing to 25 gallons more recently with the trees and pots being less then 7í in height total.

I realize I have no where near the heat and sun of Phoenix but the low pressure misters work great along with air exchange. I live in the northern prairies, last summer it went up to 38c, but with low pressure misters (only 5 heads) and 1.5 air exchanges per minute I kept the greenhouse temp under 32c. With the air exchange alone it would have been about 45c (university of florida has greenhouse temperature modelling papers on their website).

Cool, very jealous. Iíve never been able to find one to taste in Canada. I just started mine from seed 2 years ago. I looked for years but I couldnít get cultivars this far North. Is it the same requirements as sugar apple? What size of container did you use? Also when did it start flowering and how big is it now? Any other tips/tricks?

Just a bit of info from a fellow cold climate banana grower who has a limited experience.
I grew a ďdwarfĒ namwah to fruiting a couple of years back in a 35 gallon pot. I used a peat based potting mix top dressed with homemade compost. The dwarf tree had leaves pushing on the top of my 14í ceiling at 18 months. When the give the height of the plant they only mean the stalk.

Also after it fruited (57 bananas) the mother plant got so rootbound the soil wouldnít absorb any water. And the pups struggled to get large enough to flower in the same pot. When I finally gave up and cut down the tree, the soil in the pot was so heavy and dense with roots the soil was almost unworkable for composting and recycling afterwards. So donít spend a bunch of money on a good potting mix. If I were do do it again I think Iíd make a good portion of the soil from a homemade compost. Also Iím not sure what would happen if you used a smaller pot.

Evgenia, I understand what youíve been going through. For years Iíve struggled with mango in containers. I also have a tough time getting them in Canada. Iíve had a similar experience. Iím not sure what a cause the problem. I think the best way to to prevent it. The things I have found are the following. Mind u I am no expert and have only got my Pickering to fruit.

Disease resistant cultivars - pickering florigon and Valencia pride seem to have least black leaves etc
Root bound in small porous pots with fast draining soil
Very low strength water soluble fertillizer with every watering (10% strength)
Clean water - no chloride or carbonates
Misting every am when temp is cool to stop spider mites and powdery mildew
Rh <70% when hot and no wet leaves for ancathranose
Inspect every 2-3 days for scale

Best of luck

Yuhu, great link! Does anyone know how to tell when the flower is mature enough for this technique? I do t speak Spanish.

poncirsguy, when do u do this? Does that pot have a single hole in the bottom?

This is my passion fruit pot, same setup as my citrus 35 gallon. The hole is actually 1.5Ē. The pot lifters are 3D printed.

Lol down at the bottom. The white things are pot lifters, the holes are right beside them. I have the pot sitting 1Ē out of a 2Ē saucer. Iíll try to send better pics tomorrow.
