Thanks.  How log does the Vaseline stay sticky?

Citrus General Discussion / Re: Is horticultural oil safe for citrus

HardyVermont,  I have never seen (other than your post) where HO cannot be applied until 6 weeks since last application.  I do not know the purity of Southern Ag's HO product as I have never purchased the product, Perhaps that is the reason for their caution..  I use Ultra Pure HO, which is the most purified  HO on the market.  I have spayed it for years and years  several times in the same week, specially when a tree is flushing new growth, so that the leaves do not develop all twisted and deformed from aphids, and thrips feeding on them,.  I just don't care for the smell of neem, particularly when spraying inside a greenhouse or home.   By the way, it is GREAT seeing you on the forum.

Leaf burn by neem could be caused by both dosage and temperature at the time of spraying.  Personally, I do not use neem, as I prefer  a good horticultural oil, but I have nothing against neem.

Countryboy is correct, however the three rootstocks used were the three most used rootstocks by the commercial citrus industry.   This study is also going on with testing of many more rootstocks.

Luak, there is not a chance that HLB will ever be in Colorado.

Then get one growing of the root stock Swingle.

Although trees used in the study were not infected with HLB, Killiny notes that Sugar Belle® trees with Swingle citrumelo rootstock produced the greatest amounts of two compounds known to have antimicrobial effects, quinic acid and ferulic acid. Consequently, it appears likely that Sugar Belle® will tolerate HLB best when grown on Swingle citrumelo, because the two acids would probably limit the bacterial population, or titer, in an infected tree. These results led the team to conclude that, among the three rootstocks tested, Swingle citrumelo is probably the best choice for optimizing greening tolerance in Sugar Belle®.  (Citrus News)

TFN, concerning cold weather it is the other way around from what you wrote above. Spraying with horticultural oil in the fall puts plants at increased risk for winter damage and dieback.   After the new leaves have firmed up, leaf miners normally start to leave the leaves alone.

I always spray new flushes.  This keeps the leaves from being all crinkled up from aphids and thrips feeding on them,  We do not have leaf miners in my location, so luckily I never ever have to worry about them.  I spray the new flush several times until the new leaves reach good size.

Research as found leaving one fruit on a very small citrus tree, does not affect its growth at all.

Brian, if you have the right rootstock for your soil, or even close, the difference will be night and day.  My greenhouse in ground trees have reached to  the top of the greenhouse, and are approximately 15-feet wide.

Spray with a good copper fungicide

I'm not certain, but isn't FF-6-15-150 the pre released research name of Gnarlyglo?

I presently have Sour Orange seed if anyone wants to grow Sour Orange seedlings for grafting, or a Sour Orange tree.   Seeds are fresh, as I will sent them still in the fruit.

How many leaves on the tree has the damage that is shown by your picture? 

Cold Hardy Citrus / Soon To Be Released By The USDA

Gnarlyglo  is in the USDA pipeline, and is soon to be released. It is the very first scion for use as a fresh fruit containing Poncirus in its pedigree.

Phil, I'm not sure about Nordman's taste in Texas, but I think they taste about the same as a regular Nagami, only seedless.

I agree with SC2W, in that much of your tree's problem is Arizona's extra hot sun, and that it is a young tree. Try to help shade the tree for a while,  It is now the middle of August and temperatures should start to lower.  The tree also looks under fertilized.  What is the fertilizer formula and what trace minerals does the fertilizer you used have? It should be written on the bag. How old is the tree, (how long has it been in the ground)  2 year old in ground citrus trees are fertilized 5 times a growing season, 3 year old citrus trees 4 time a season, and 4 year old trees and older 3 times a season.

Mtlgirl, the answer to your question concerning HO, no it is because HO actually kills an open citrus flower when sprayed on it, therefore that flower cannot produce its fruit.

Zitrusgaertner,  I can see you do not know of Dr. Malcolm Manners, or you would have never asked that question.  Dr.Manners  holds the Chair of Citrus Studies at Florida Southern Collage. He is one of the best known minds concerning citrus in the USA.

I once ask Dr. Malcolm Manners if citrus trees started from seed were more cold hardy that grafted trees.   Dr. Manners said no.

Nice things happen to those who wait.  Great story. Thanks SC2W for thinking of us.

Citrus General Discussion / Nordmann Kumquat & Where Did It Come From
« on: August 12, 2018, 08:49:05 PM »
Nordmann kumquat (Fortunella margarita “Nordmann,” Citrus margarita “Nordmann”): What is the Nordmann kumquat, and where did it come from?  It came from a Nagami kumquat tree growing in Mr. George Otto Nordmann’s citrus grove.  Out of the many trees in his grove, one of George's trees was found to have a surprise mutation.  That special tree started producing seedless Nagami fruit.  The new mutation was named after the grove's owner, George Nordmann. Nordmann kumquat is a great hand-to-mouth treat directly off the tree, and there is no seeds to spit out. You can also slice some into salads or add some juice or fruit into desserts, baked goods or preserves.  I like to squeeze some juice into a Coke.

You will find the seedlings very easy to separate.  You can do so any month of the year, if not any day of the year.  There is a common nursery saying that a tree should be transplanted when it is 2 times the height of the container.  Transplanting once a year, or at the very least 2 years is also a good rule.

TFN, the peel scaring on your fruit is caused by an insect called a thrip.  Thrips are a sucking insect, as they feed on the peel it takes away the chlorophyll.  Actually not much damage to the fruit.  Can be controlled by a routine HO spay.
