I learned at one of the SE citrus expos or on this forum that the psillids are not killed by freezing weather, and that there is greening in coastal SC and GA with quarantined counties. I'm wondering if the psillids will be able to use other members of the rue family to spread throughout the continent. The "toothache tree" ranges natively from FL to Canada.

I'll answer my own question: Just make it about 12 to 15 inches long. Go with what feels right. Use your instincts.

Citrus General Discussion / Air propagator question.
« on: June 19, 2017, 09:44:53 PM »
I have some of these air propagator clam shell devices and want to try it on some citrumelo branches. How long should the branch be that I'm trying to root? I have the small and medium size propagators.

P.S.  These are trifoliate hybrids and Ichang lemons. Can I root cuttings from these water sprouts?

Cold Hardy Citrus / Water sprouts on freeze-damaged citrus
« on: June 19, 2017, 08:52:50 PM »
I'm sure this question has been aswered already, but I missed it: I have severe freeze damage and lost upper half of trees. New growth coming out on branches that survived two, three, four feet from ground. Vigorous sprouts coming up from base and trunk of tree. Do I remove the sprouts that are trying to form new multiple trunks to encourage growth forming higher up, or leave the trunk/base sprouts to help build trunk caliper, supply glucose to root system, and help shade trunk and protect from sunburn?

Irregular yellowing of leaves; hopefully not greening disease.

The only thing that survived this winter here unscathed without electric heat for protection was my Dunstan citrumelos that had no protection at all. All other cold hardy hybrids with Ichang or trifoliate heritage got knocked to the ground after a 14 degree night and a 16 degree night in late March after mild February.

Sorry for your loss Vugearhead.

Good luck! Lemons on trifoliata?

Slime mold flux disease infected one of my wild crabapples and now is killing a redbud tree. I noticed discoloration of patches of bark on the crab near where a major branch broke near trunk and death spread over a year systemically throughout the tree with dieback noted in canopy until I had to remove tree. Redbud is huge and green but loosing some small branches and big sections of bark on trunk popping off with noted wet-looking dark discoloration of bark. Extension agent told me no cure for it. Just have to clean pruners with bleach water solution between cuts. Don't know why red bud got it since I don't prune it. Crab got infected because I failed to prune out busted branch near trunk; couldn't reach it well since wild tree so thorny. Maybe your tree got infected from mower damage on exposed root?  Hopefully yours isn't slime mold. Can you post pic?

Good for you, Luak! Boldly go we're no one has gone before! You're a citrus pioneer! Good luck!

Fascinating post. Maybe those varieties will become more popular and more readily available in the future.

Could a high concentration of phosphorus/triple phosphate  in soil cause such early blooming?

Sounds like a good idea to me; dwarfing and cold hardiness. I'm a fan of that.

After reading your post again, I bet you could graft all of the above onto the callery pear. The pear is a heavier frame tree so the more slender Rowan and hawthorn limbs would be better served as part of upper body of tree instead of rootstock for a pear graft.

I would be concerned with viability of sorbus in a tropical/subtropical climate. Sorbus aucuparia grow like weeds for me on top of a mountain in 6b, but most sorbus/Rowan/mountain ash are happier in zone 5 and lower as I'm sure you've studied. Our native Sorbus Americana was at one time classified as pyrus Americana. From what I've studied, Sorbus readily hybridizes with other members of the rose family. I have a locally grown hybrid Rowan from wild gathered seeds that flowers profusely at a young age every year and produces fruit and flowers all along the lengths of dropping branches. Rowan and callery pear are both vigorous growers; don't know why one would graft one onto the other, but good luck in your efforts. Let us know about results.

What does sunburn on citrus tree look like? Mine defoliate in winter, so may they be sunburned?

Cold Hardy Citrus / Am I safe to prune yet?
« on: June 04, 2017, 11:19:00 AM »
My defoliated freeze-damaged citrus hybrids are putting out sprouts at base of trees and some sprouts on low branches but higher branches that are still green are not sprouting yet. Am I safe to prune or dead brown branches yet? Will pruning at this point stimulate or hinder growth? Should I wait for asprout to from on a branch before pruning the dead end off of the branch?

I found out it is an Italian feminello lemon variety that is popular with making limoncello. They are currently out of stock at Four Winds in CA.

Is Santa Teresa a variety of citrus? Never heard of it.

Citrus General Discussion / Re: Meiwa Kumquat fruit have no joice
« on: May 31, 2017, 07:35:06 PM »
My Meiwa are not really juicy either. The "Hardy Citrus for the Southeast " book by Tom McClendon says about Meiwa, "with a tender peel and very little juice." We eat Meiwa for the sweetness of the peel. I think of them as citrus gum balls. The only weird thing I find about eating the kumquat is chewing up the seeds, otherwise I find the Meiwa quite enjoyable. Maybe your fruit got some frost damage that caused the pulp inside to shrivel. I noticed one of my grapefruit had dry shriveled pulp that was dry after freeze damage.

So tragic. I hope citrus doesn't go the way of the chestnut.

Try calling Stan Mckenzie at Mckenzie Farms in SC or some other grower of cold hardy citrus since those folks use PT as a rootstock, they will have fruiting PT trees.

I only have two trees old enough to bloom, and only harvested three fruit last year. This year my trees were covered with flower buds when the big 14 degree freeze hit in late March, and I'll have no fruit this year.

How do you plan on processing the fruit to make it edible? I've heard of people making marmalade out of it. Maybe could process a lot of fruit when it comes in to use all year long. Interesting. Maybe I should add more poncyrus trifoliata trees to my orchard. That would be ironic if we started growing and selling PT fruit on large scale.
