Cold Hardy Citrus / Re: Cold Hardry Grapefuit/Pommelos
« on: February 10, 2018, 09:50:46 AM »
My young, first year in ground oro blanco grapefruit withstood 16 degrees (-8.89 degrees celcius) one night and 17 degrees (-8.33 celcius) the next night.  It lost all leaves and the new green growth it has looks fried, but the mature growth is still alive.

Hit 16 degrees one night and 17 the next.  I believe all survived above the mounded dirt with only leaf loss and small twig dieback including red grapefruit, navel, and minneola tangelo.  I didnt offer any protection other than mounding dirt above graft line to ensure scion survival and hosing the ground with water prior to midnight to have add a little extra warmth.

For a quick way to throw some protection on the stem above the graft line, i make at least a foot diameter circle around the trunk with cardboard and fill it with dirt as high as i can.  I then pack it so there is not a gap when the tree sways in the wind between the trunk and dirt.  It looks this far as most of my trees have pulled through with multiple nights around 20, one down to 16, and one to 17.  There is some damage but it does not appear to have killed any above the dirt.  A lemonquat looks to have taken significant damage.

Citrus General Discussion / Re: HLB Getting Worse in California

Unfortunately without a cure I do not see the spread of HLB in California slowing down.  There just isn't enough of cold temperature drops to decrease the ACP population.

Does anyone know any source for the lilly pilly in the U.S.?

Justfruitsandexotics have a few satsumas including xie shan.  Its in northern florida.

I cant tell you anything about Orlando, but i abhore almost all citrus from California as it never tastes good but somehow i am never disappointed with a minneola from there.

I have all arbequina.  They started off slow but are growing a lot faster now.  I have had a few olives here and there bit not enough for a harvest yet.  They dont seem to have issues with the cold at all.

Neem oil/insecticial soap kills the acp and its nymphs.  I dont think you can grow citrus without the soil drench imidacloprid in central and south florida due to how pervasive citrus greening is.  I dont know what people are doing in your region but there are some on this forum that do have citrus growing there.  I

That appears to be the asian citrus psyllid nymphs feeding on your tree.  The white strings is their excretement.  Do not let these remain on your tree as these spread citrus greening.

I dont know if there is a difference between a sunquat and a lemonquat, but I am a big fan of the lemonquat.  It is my favorite lemon by far, even over a store bought lemonade lemon.

Citrus General Discussion / Re: HELP! Sick trees!

Leafminers come back every year here but dont become active until May or June.  All growth next year until the leafminers appear will not have the damage to the leaves (citrus leafminers for the most part only attack the new growth).  You can get soil drench pesticides to kill them or just let them be.

The question is how quickly do the current tests identify whether the tree is infected with HLB?

Those are citrus leafminers.  Nothing to worry about unless it is a young seedling.

Citrus General Discussion / Re: Asian Citrus Psyllid Survival
« on: August 16, 2017, 04:45:23 PM »
Hopefully they will find a solution.  I think the least controversial if they can't cure the disease itself in infected trees would be to either breed specifically for or genetically modify the acp to not transmit the disease and release those insects to breed.

Is there a specific type of mesh/screen that needs to be used to keep out the acp?  Additionally, if ants transport the acp, how could they be kept out froming coming underneath the screenhouse?

Aren't the trees kept indoors where the acp can't get to them?

Temperate Fruit Discussion / Re: Mulberry Thread.
« on: July 22, 2017, 04:11:13 PM »
I am interested in the white pakistan mulberry.  Any opinions on it? And does anyone know of a source on it (I see justfruits but they haven't had them in stock in a while)?

Well that is not good news.  I was hoping our colder winters would prevent the spread of it here.  I haven't noticed any acp in my area but will have to be even more proactive in inspecting.

Cold Hardy Citrus / Re: breeding cold hardy pomelo
« on: June 17, 2017, 11:52:23 AM »
Doesnt bloomsweet grapefruit have a high percentage of pomelo in its dna?

What is the chestnut story please?

Chestnut trees used to be 1/4 of eastern forests. Around 100 years ago a chestnut
blight got accidently imported and wiped them all out. American chestnut to this day can't
survive anywhere. Some hybrids american x chinese chestnut can survive.

The American chestnut can survive (already growing trees), it just cant reproduce.  The trees growsx blight knocks it down to its roots, and it grows again.  Citrus may have to be grown in areas where acp cant survive.  Hopefully a cure is found soon.

Thanks for the responses.  No goats or kids running rampant.  Maybe something shot out of the lawn mower?  We dont live in a neighborhood so i think that would be the most likely cause.  I was just hoping it was any kind of disease.  Would that greeb tape harbor water and promote rot?  I was thinking of covering it but did not want to have the cover hold water and result in rot.

Citrus General Discussion / Issue on bark above graft on meyer lemon
« on: June 03, 2017, 11:14:26 AM »
I didnt notice this until yesterday, but underneath the canopy and above the graft, there is a chunk missing out of the bark.  Fire ants are going in and out of it.  I dont know if it was cold damage from this past winter or what is the cause but i want to know what to do.  This tree right now appears to be completely healthy and is currently the most vigorous out of 25 or so citrus trees that I have.  It appears wet because i sprayed some diluted hyrdrogen peroxide in it prior to taking the photo.  Does anyone know the cause and/or a solution to this issue?

Here is what the tree looks like from above showing no symptoms of the issue:
