Citrus General Discussion / Re: Please help with my limequat tree!

Those aren't psyllids, which are the vector for HLB (citrus greening).  Look to be fungus gnats or something innocuous.  Fungus gnats in small numbers are harmless though in high numbers in a pot might chew on a rootlet or two.

Iíve been picking them in November/December. Perhaps September would be better. My other citrus nearby do not suffer from dryness.

Citrus General Discussion / Re: Flying dragon variety: Snow Dragon
« on: May 08, 2020, 03:20:22 PM »
This is mine after 15+ years in the ground. Long before someone made up the name "snow dragon"...

Its amazingly small for a 15 year old tree.  I suppose lack of chlorophyll limits its ability to fruit or grow.

Citrus General Discussion / Re: how to prune
« on: May 08, 2020, 03:16:34 PM »
Citrus tree growth is upright in most varieties. During the first years, there is no need to prune, since research has shown that any cut to a young tree reduces root growth.  This is due to the equilibrium between foliage and root system.  A citrus tree is a biological unit.  Heavy cuts on a young tree discourages canopy growth and delays the tree to  come into bearing.  After a few years, depending on the speed of the growth a selective canopy THINNING may be carried out.  The choice of branches to eliminate is based on the concept that any space within the canopy must be covered by only ONE branch. It is not wise to let surplus branches occupy the same aerial space. It is important that thinning does not deplete any canopy sector. A harmonious citrus tree grows to an almost round shape.  Vegetation free canopy spaces must be avoided since they reduce yield.  In citrus areas such as the United States, Brazil, etc. pruning is either practiced rarely or not at all.  Unpruned trees come into bearing quickly and yield crops for many years. After many years of growth crops are reduced and fruits become smaller.  This is the time to make heavy cuts and renew growth.
I have a 20+ year old in ground meiwa kumquat that had become quite empty in the center. Since the tree has become too wide for its spot, I pruned some top branches in order to get more light into the center of the tree hoping it would cause new growth closer in the main trunk.  That has been slow but seems to be coming along.  Once that takes hold I will prune the side branches (this fall) that are pretty leggy so as these send out new growth I will have a nice full canopy that is closer to the trunk.

It is 32'x18' with 15' peak in the center.  There's another thread on here documenting all the construction, it was a ton of work to build!

I am lucky enough to have piped natural gas which is extremely inexpensive, so I am using a gas air heater.
Ah, yes!  Natural gas is the most economic way to heat anything.

My Chandlers are always dry and tasteless.  Maybe I should pick then earlier when they are still rather green instead of waiting till December when they turn uniformly yellow.  if that doesn't work, it 11 years wasted and I will have to replace.

Yorgos, Bomand,

Thank you for the warm welcome and advice! I am very familiar with leaf miners and my comment was made because i saw the deformed leaves but no line paths inside them. I will search for Bayer but i know as the tree becomes older it will provide its own defense alongside what I can do.

I was more concerned about that wasp. Someone locally mentioned to me it could be a borer and I freaked a little. I found these other guys too. One looks like a wasp and the other i have no idea. Both are very tiny and zoomed in almost all the way on my phone. Are these guys dangerous?

Sorry, I feel like a first time parent! Lol

The top pic is an immature grasshopper of some sort. Unless you have lots of them any damage they do is minimal so no worries.  The bottom is an ichneumon wasp. These wasps are solitary, do not sting but deposit their eggs in caterpillar or larval hosts. They are a beneficial insect.

Definitely leaf minors.  Bottom pictures reflect that clear enough.  As to the insect on the first pic, it's not a robber fly and looks to be some sort of solitary wasp or possible a moth imitating a wasp. Need some more pics to be sure. Either way, it is doubtful that it is bothering your citrus.  If it is a solitary wasp it is likely helping your citrus as a predator of other insects.

Looks like a thrip.

Citrus General Discussion / Re: Blood orange not flowering

It took my Moro and sanguinelli  blood oranges 4 or 5 years to begin producing after planting. And they exhibit  a very strong alternate bearing tendency. 

Citrus General Discussion / Re: What is flowering now for you?
« on: March 24, 2020, 11:18:45 PM »
Oh, well.  The satanic, bushy tailed horde are pretty much taking all my green peaches. History repeats.  Star Ruby grapefruits and oranges (n-33, Moro, sanguneli) are blooming nicely! Loquats are tasting great now! Ujukitsu has more flowers than IV ever seen.  So does Chandler pomelo.

All my citrus are blooming except Bloomsweet GF. It had a pretty large crop last year so it might be in its alternate year.  Also persimmon, and peaches are bloomed out with a tons of ping pong ball sized peaches. Need to thin them out.     

Citrus General Discussion / Re: Recommendation on citrus to plant
« on: March 06, 2020, 04:32:32 PM »
Plant them both.  Use the High Density Home Orchard approach.  Place them just three or four feet apart and treat them like one tree. For a home owner you get plenty of fruit.  For commercial harvests the crop is lessened but for homeowner use its perfectly fine.  So instead of 400 fruits from 1 tree, you'll get a couple of hundred on each. This assumes the growth habit on the two trees is approximately the same so that one doesn't take over the other.

My New Zealand lemonade tree must be 5 or 6 years old.  It had a ton of fruit this year, I let the fruit hang on the tree until they turned completely yellow, doing so, the fruit had a sour sweet taste.  Very good,
I have an ujukitsu lemon that was all the rage when I got it 10+ years ago.  I have not been impressed.  How does NZ lemon compare to the ujukitsu?

That is good news. So spraying in the evening, regardless of ambient temperatures, is go!

yorgos, can't you spray in the evening?
It often doesn't get below 90 until 10-11 pm here in the summer. I can't imagine spraying at midnight or later because 1: I couldn't see what I was doing, 2: neighbors would peg me as crazy and 3: I need my sleep.

Very few flower buts on my moro this year (2nd year in row)  :(,  but my ruby/sanguinelli have a lot of flowers buds.

It's been a warm winter everywhere, maybe it has an effect. Especially the sun rays are stronger.
It may be a warmer period we are in, but the suns rays have not changed one iota and are the same as they always have been.

It gets pretty hot in Pennsylvania in summer, but the growing season is short.  I have my greenhouse foggers set to keep it under 95F or else it would be >110F inside on sunny warm days.  Even in the winter if it is 40F outside but full sun the greenhouse will easily be 80-90F.

I will simply wait and see how the next couple crops turn out.  The tree is growing rapidly, it should easily reach the greenhouse roof/fans in the next couple years.

I'm sure it gets hot in PA.  In the Rio Grande valley that produces the best GFs in the world it gets into the 80's and 90's by April (if not earlier) and strays hot until Thanksgiving. With you greenhouse temps you have a shot at some pretty good GF.  At least they look great!

Im growing moro, sanguinelli, tarocco, and vaniglia sanguingo.  Intend to keep only one, not sure which yet.
I am growing the first three you listed.  Only the moro colors up at all and here on the upper Texas Gulf Coast it does so sporadically.  Some years a little better than others. Never like what you see in the store.   The sanguinelli & torocco taste fine but never have I picked one with any hint of color. (Even when picked into March) They all have been in the ground about 10 years. My biggest complaint is the habit of all 3 varieties to be severely alternate bearing.

Grapefruits need a lot of heat as they develop to achieve desired sweetness.  Not sure Pennsylvania gets hot enough for long enough to allow a grapefruit to ever get very sweet. Even here in Houston I have to let my Rio Red GF hang into January at least to get the sweetness I like.  Your fruit looks great and hopefully in the green house you can give it can get enough heat units to develop the flavor you want. 
Also, the fruit tastes better as the tree matures.  My in-ground GF is about 10 years old and really it just began developing the wonderful grapefruitiness flavor I love the past year or two. Your tree just may need more time.

Yorgos, for Chandler pummelo you need to keep the soil moisture levels up.  II used to have the dry problem, but after paying attention to the moisture content my pummelos produced wonderful fruit.
Thanks Millet. Something to look after. My chandler pomelo grows close to a bloomsweet grapefruit and gets the same water regimen.  The bloomsweet's are wonderful tasting, no hint of dryness.  would pomelo be more sensitive to uneven watering than a grapefruit?

First year of moro oranges too...


While my moro's don't color up much where I live, when they do they are more red/purple that these appear.  These pics remind me more of a cara cara navel from the color. Could just be the color in the photo. Nice fruit regardless!

How was last year's crop?
Last year was a moderately heavy crop, hence the manifestation of alternate bearing on this tree.  The mite infestation is not helped by my reticence to spray in July, August and September when the temps are in the 90's all day long (which, sadly, coincides with the mite population explosion). 

I usually use a neem/spinosad regimen in the spring, alternating between the two when I do spray. I read that neem and insecticidal soap are the worst sprays during hot weather.  So is my choice only spinosad?  Any other treatment recommendation?   
Last years Moro crop did color up some but only with some reddish streaks. Toracco and Sanguineli's have never shown even the slightest hint that they are blood oranges.

My 10 yr old, in ground Moro only produced a handful of fruit this year.  Pic is of a just picked orange. Winter has not been that cold but we have had quite a few low 40ís to 60 hi days but as you can see no color at all.  Last year had a fairly large crop from this 18í tall tree.  Also, rust mites love this tree more than any other of my citrus
