Overwintering tropical fruit trees

Your tent and a thermostatically controlled small heat should work. Put it close to the cabin as possible with a southerly exposure. I over winter dwarf citrus in 15-20 gal pots: I built a roofed porch with removable glass panels with a thermostat heater as I get up to 110F summers and 19F winters. Move them into porch around mid-November and out late March. I have 4 banks of double 4ft fluorescent tubes for supplemental light and SE sunlight. One lime and one lemon are 25yrs old; orange and mandarin are 20 yrs and and other lemon and kumquat are 10yrs.

Wow huge pots. how tall is the orange? I have a calomondin and a blood orange, a key lime, a meyers lemon and a mandarin they r lovly. Now in 2 gallon nursery pots. Is that ok? There is southern exposure on the side and that is where I was thinking of putting the pop up greenhouse. Thanks for the help.

Orange is roughly 6 ft from soil line, as is one of the lemons; I usually trim them down a bit when going to porch. Growth is pretty slow during winter, though they do flower and set some fruit. I don't fertilize during winter unless I detect deficiencies as I really don't want much growth...they are in a holding pattern.

You haven't said how old yours are. You should pot up to at least 5gal and that should be ok for 2 or 3 yrs

Not sure how old these r. I just received them this past month
I said they were cloned, lol, in op but I am just guessing they r this year's. One banana, the mango n the mandarin are around 20 inches tall. The others are around 12 inches. I have 5 gallon nursery pots here n can transplant. The soil I have has fertilizer in it. Selection is limited here. As I get familiar with nurseries I'll scout for better soil. My hens will be helping with fertilizer come spring. Surely you have help.moving your orchard to the porch.Here it is just me n I need to comw up with a more permanent solution before they get too big. I just moved here but haven't decided to stay... Sorry for typos, I just have internet on phone.

Just me as well. I use a dolly (hand truck). I just assumed yours were older and bigger; don't know much about the others, but I would TP the mandarin to a 5g. I am thinking about building a small exclusive greenhouse for them, and plant them in the ground inside it. Its getting old moving them around twice a yr for 25 yrs lol

OMG ! Yeah you r very dedicated. There is a very large concrete pad here on the property that I was going to put the cabin on when a septic was uncovered elsewhere n there were severe drainage issues that had to be corrected so I used the existing septic to save money n now I have a lovely concrete pad that is over 30 x 30 looking like a big parking lot. I had thought of putting a greenhouse / temple there n if I stay (n if I can ever afford it). It is in a beautiful spot for it
I'd love to hear more of your plans n hope they happily unfold soon for you. I think it is very doable.

Hope you can stay...I'd kill for that concrete pad LOL. I retired 2 months ago and have a project list a mile long.

This was a mistake that I hope can b corrected next spring.
