Temperate Fruit Discussion / Re: Leaf Scorch?

Trilogy’s tracker, it may depend on what constitutes “wet feet” for paw paw. They naturally thrive in flood planes. Also, once established, they do well with n full sun. Mine thrive well in a climate similar to yours but on top of a mountain on a sandy slope with high winds often. Maybe it’s not a burn on the leaf but a fungus or other disease. Either way, I wouldn’t worry much since paw paw is native and I’ve found need little to no care. Nice green leaves. Must get plenty nitrogen.

My lows the past three days have been in upper 40’s F, highs low 60’s. My first freeze is usually between Halloween and 11/11.

Sorry to hear of Stan’s loss. I still have one of his Kimbrough satsumas with fruit on it; maybe I’ll bring some to the expo. Laaz, did his Ichang lemon and citrumelos survive?

As a jam/jelly maker, I found this very interesting and informative. I've never had enough home-grown citrus to make marmalade ( except maybe Meiwa or satsuma), but maybe one day. I think Ben Salley in Columbia sells satsuma jam. Thanks for the ideas, Millet.

Do you have well water? Looks like calcium deposits to me. Try wetting a cloth and wipe the deposits off just to clarify that's what it is.  Could be spray residue from whatever you may have sprayed on plant. Leaves look healthy.

Laaz, my tree never fully greened up or grew this year. Just put on leaves but no height. All my other citrumelo and trifoliate hybrids died except a Thomasville and citradia that surprisingly came back from the roots. One citradia leafed out, started growing, and then within a few days just died to the roots. I won't be surprised if this last citrumelo dies this winter. I plan to replace it with a lilac or native hydrangea.

Well, after reading more on phytopthora, that or some other root rot is probably what I have here. Despite have well drained soil and being on top of a mountain with no really flat ground to cause ponding of water, we have had a lot of rain this year and even my rhododendron bushes are dying back some. My antique roses in a raised bed are dying back also. Maybe I'll lose everything. We will see. Thanks for the info guys.

I did notice a small crack in base of trunk on south side that I figure is from winter trunk split damage but there is no discoloration or gummosis or sunken areas anywhere on trunk. The article Lorenzo shared mentioned phytopthora living in citrus-producing areas, which is definitely not where I live. Perhaps phytopthora can live outside subtropical regions too? I planted this citrumelo in a spot where I had a large native crabapple that progressively died of a disease that worked it's way systemically from the distal parts of the branches eventually down the trunk, with leaves and bark wilting and turning black; I figured it was a bad fire blight infection that took hold despite pruning and treatment with agromycin. It's nearby sister crabapple died similarly the year before from what local extension agent told me was slime mold disease in trunk that originated from split branch near trunk where infection set in. I replaced it with a rowan tree that grew well for a year or two and then died from the base of the trunk up but tried to come back from base of trunk. Extension service told me the slime mold disease doesn't reside in soil and shouldn't infect another plant planted in the same spot. Don't know.

Cold Hardy Citrus / Re: Grapefruit that grows outside in England
« on: September 28, 2018, 08:15:56 PM »




This pink fruit is my Rio Red grapefruit that fell off tree in late October 2017 and the yellow fruit is my Croxton that was harvested or fell off, I don't remember, in late January 2018. My Croxton fruits have only at best had only a tinge of pink colored flesh. I think it doesn't get warm enough here for my grapefruits to fully mature.

I like my Meiwa. I eat them like citrus gum balls. Someone on here mentioned making marmalade out of them. Mine just started blooming now. Much later than  last year. I think it didn't like the cold January we had and some of my fruit froze on tree.

We have had a lot of rain this year. However, my other citrus don't look like this. Well drained soil. Did have voles eating nearby guara bush roots though. The tree seems tight in ground but maybe some root damage from voles. My other theory was that it never fully recovered from winter and now the tree is trying to shed the older damaged wood and recover by sending up new suckers from base of trunk.

Isaac-1, you're right. I should check the pH. I've checked it all over the property before and it's always been about 6.5. I should check at that site though.

Cold Hardy Citrus / Re: Swamp Lemon Adventure!
« on: September 17, 2018, 10:22:32 PM »
I think I may have already alluded to this theory earlier in this post/thread, but the current flood waters in eastern NC are probably not good for any citrus, swamp lemon, or not. Almost all of eastern NC from I95 east is under water. This is not a rare occurrence for this region since rivers there are prone to flooding historically speaking. I didn't see poncyrus in Whiteville area perhaps because they'd been flooded out of existence long ago. The search, however shall continue.

Maybe it will be similar to a citrangequat but with more poncyrus traits.

Cold Hardy Citrus / Re: Grapefruit that grows outside in England
« on: September 17, 2018, 09:58:21 PM »
From what I've briefly researched, London, England has a mild maritime climate with cool summers and warm winters with temps seldom below freezing. I think the citrus grows and survives there because it doesn't freeze much. I agree with you on the poor development of fruit due to lack of warm weather; my two grapefruit trees produce similar fruit to the ones shown here, with large pith and poorly colored flesh. It seldom reaches 90 degrees at my house in NC mountains.

Dunstan citrumelo. Has lush green sucker coming from base and rest of tree is yellow. Been fertilizing with miracle grow and super thrive. Suggestions?

« on: September 09, 2018, 09:59:56 PM »
Is this because they know the trees will die small from greening,so want to pack a lot of small trees onto a lot to maximize production before having to replant?

They said on the Making it Grow show on Tuesday's on public  TV out of South Carolina that trifoliata is invasive in SC and is actually plugging up creeks and streams there. Coastal NC where swamp lemon supposed to come from is a similar climate with live oaks, cabbage palms, palmetto bushes,etc.  I didn't see anything resembling trifoliata in the immediate vicinity of where it was found in the past, but maybe one day when I have a three day weekend, I'll take my kayak down there and explore waterways.

Temperate Fruit Discussion / Re: Paw Paw questions.
« on: August 18, 2018, 07:22:14 PM »
Paw naturally grow on fertile soil along edges river and creeks and in flood planes in the woods. They like drainage and plenty of water. I've seen them and gathered fruit from the wild here in the mountains of NC along sides of creeks in flat areas where creek is about 3 to 5 feet below edge of the flood plain. These grow to be high trees with rather large trunks. They don't like their roots damaged at time of planting and need a long tap root to form before seedling will break surface of soil, hence usually grown from seed in tall pots. My trees are planted on top of a mountain in NC in deep sandy yet black soil with good drainage on a gradual slope, which is not their native habitat; they are found wild in the valley along side river/ creek with better access to water, not on mountain top. Therefore, I make sure to mix plenty of compost into planting site and mulch around trees with homemade shredded leaf/tree matter to help promote moist soil. They don't start to bloom until about 5 feet tall in ground. I wouldn't expect great results over the long term in a pot.  Paw paws are wonderful and strange native trees that unlike other domesticated fruit trees have picky root systems initially, but once established in ground, can withstand some drought and don't need pruning or spraying with insecticide and are pretty much unmolested by deer and bear predation up until harvest, unlike apples and pears and drupes.

Looks like the Southeast Citrus Expo will be in Valdosta November 16 and 17th this year. I hope to attend.
