The Tropical Fruit Forum

I can’t find old-fashioned Christmas lights and my POA won’t let us do Christmas lights for half the year anyway. I’ve wondered about propane patio heaters but I don’t think it would be economical nor would the heater last more than a few hours.

These are photos I took of Nansho dai dai, tiawanica at the Armstrong Arboretum in Savanna, GA.

I plant in spring after last chance of frost, after mother’s day. That way, the plant has a chance to put on more girth before freezing temps return in late October.

Will2358, citrus aurantium is usually called “sour orange “ and makes lovely bright orange large fruits and has large unifoliate leaves and is not supposed to be hardy much below 15 degrees F; however, poncirus trifoliata, otherwise known as bitter orange or even bitter lemon by some, is hardy to -15 degrees F and has tripled leaf pattern. Big differences actually. Notice in my pic that the swamp lemon which is a form of poncirus trifoliata and the poncirus and pumelo hybrid citrumelo have trifoliate leaves and the sour orange is large unifoliate or single leaves.

Mine here in NC finally died after years of dying back despite protection in a high tunnel with water barrels. I took a pic of one at Armstrong University in Savanna and it had fruit on it but looked pretty rough.

I have a bunch of PT seedlings. I remember someone on this forum wanted a bunch of fruit to treat cancer. I’ve tried to research treatment of cancer with PT but can’t find anything telling me how to process it or who I could be a supplier of fruit for. Anyone know of a profitable industry for poncirus other than root stock?

69 degrees at my house when I got home from work today at 4:30 PM. Was in the 80’s in Asheville, NC at work. My satsumas are blooming now so I’m glad we’re past the threat of freezing here.

My poor citrumelo is making a comeback. Green leaves this spring. Yay!

I’ve been to JC Ralston Arboretum in Raleigh, NC last October.  I saw the fruit on the ichangensis calveleri ( sure I misspelled it) and it was small ( size of my thumb) green,oblong, and did not look like ichangensis that I’ve seen before. The citrumelo they had was full of fruit and Dunstan type. The “citradia “ they had was also full of what I’m pretty sure is Swingle citrumelo fruit. They got the citrus trees from Woodlanders nursery in Aiken, SC. I’ve discussed the fruit discrepancy with the owner of Woodlanders and showed him photos of the mislabeled “citradia “ tree and he agreed that it is Swingle. It’s a beautiful arboretum, but they don’t know cold hardy citrus hybrids; it’s NC which is not citrus territory.

Ilya, is peel sweet like kumquat?

That’s true. Why didn’t you prune the dead wood last year during growing season? What does MIC stand for?

Thanks, guys.
