Citrus General Discussion / Re: Fungal disease on new flushes?
« on: May 23, 2022, 09:17:25 PM »
Fungicides ae usually needed for adequate control.  Maneb, mancozeb, chlorothalonil, metiram, strobilurins, and copper fungicides are the most widely used products.  Where the disease is severe and environmental conditions are favorable for he pathogen, several applications are usually required to produce acceptable control.  In humid climates, applications begin when the spring flush is one-fourth expanded  Where humid conditions exist, follow-up sprays could be required.   Good Luck with your tree.  We would appreciate hearing out how your tree is doing.  (Taken from the Compendium of Citrus Diseases.)

I never tasted a Lemonquat.  I did have a Sunquat some years ago.  It was not worth keeping and tossed it out on the compost pile.

Citrus General Discussion / Marsh Seedless White Grapefruit
« on: May 21, 2022, 04:21:07 PM »
In Colorado the temperatures are not high enough to sweeten white grapefruit as sweet as Florida grown fruit.  Therefore, I have continued to leave my Marsh grapefruit hang on the tree until the end of May.  Over the months I sampled a fruit every couple weeks.  And every couple weeks the fruit became a little sweeter.  Today, the 21 of May I ate two of the grapefruit and they were quite sweet.  I noticed that when I picked them they were also some what soft and  juicier .  Time heals all things.

First, your tree is still small, and has a corresponding small root system.  The roots most likely extends out about the same distance and the above leaves Poncirus guy recommendation to remove the grass from under the tree is one thing that NEEDS to be done., as it is surely robbing most of the available nutrients from the tree.  I would remove the grass to match the trees drip line. Further, what has been the tree's nutrient plan.  A young tree such as your needs should to be fertilized 4 times equally spaced out during the growing season (March through September)  You can use 6-6-6 or 10-10-10.

I agree the tree doesn't look all that bad.  Note: the highest period of leaf fall for a citrus tree is during flowering.   Your tree does look a little undernourished.  A three year old citrus tree should be fertilized 4 times a year equally spaced out during the growing season (March - September).

Sour orange petioles are not slender but are quite winged.

Citrus General Discussion / Re: when to pick Chandler pummelo?
« on: May 13, 2022, 09:00:13 PM »
I have not seen them dry much, but quickly deteriorate, especially after falling from the tree.    After falling from the tree the fruit will quickly become soft and  start to decay.  The pummelo that I have seem perfectly fine to eat when quickly picked up after they fall from the tree. The best time is to pick them (especially grapefruit) when a slightest twist easily removes them from the tree.

Olivier, are you watering your trees with municipal water or well water?   If municipal water, you can get the water's composition from your supplier.  For well water you will need the water tested.  Could very well be from high levels of carbonates and bicarbonates.  When I stared growing citrus I used my well water, and the trees had all sorts of problems due to high  levels of bicarbonates.  I switched to a mixture of 1/3 well water and 2/3 rain water and my trees quickly returned to good health.

I believe it is just the result of the transition from the inside to the outside.  Many growers set their trees in a shaded spot for several days to a week before placing the tree in the direct light of the sun.

Citrus General Discussion / Re: sunburn from led lights?

Thousands of citrus trees in Florida are grafted upon Carrizo. The humidity in Florida reaches up to 100%.

Many container growers grow in a 5-1-1 medium or a 50/50 peat turface MVP medium. The 5-1-1 medium has been thoroughly tested over the years,  the 50/05 medium is a relatively (several years) new blend.

I don't think the single leaf you show was caused by over fertilizing.  Over fertilizing damage normally shows leaf burning or scorching.  It is impossible to determine a tree's problem from seeing just one leaf. It would be much better to show a picture of the whole tree rather then just one leaf.

I would guess it is, since the tree that the CCPP has in it inventory was grown from seed,

.brian, the trees you show look very well balanced, healthy, and amazingly well taken care of.  What is the mix you are using in the shallow containers  (turface & MG) or 5-1-1

Single.  Spray to get good coverage, upper and lower leaf surface, but do not over soak the tree.

Citrus General Discussion / Re: Horticultural Oil For Insect Control
« on: April 30, 2022, 01:08:14 PM »
Ultra Fine horticultural oil (the brand I use) vaporizes off of the leaves in approximately 1+- hours.  Therefore, it does not clog the  stomata for days and days, letting the leaves to breathe.  Various cooking oils remain coating the stomata for longer period of time.


JACK'S 25-5-15  contains Mg 0.1%,   Sulfur  .130%,  Boron .0125%,   Chelated Copper .0125%,  Chelated Iron (Fe) .125%,  Cheated Mo .0125%, Chelated Mn .0630%       

You have done well growing that tree.  It looks very healthy and balanced.

Yes you can use it on inground trees but it would be expensive.   I would recommend you purchase a 50-lb; bag of 8-8-8 or 10-10-10 and sprinkle it evenly under the tree out to the end of the drip line.   Then use you sprinkler and water it in.  For trees the age of yours apply  this 3 times per year equally spaced out during the growing season.

Poncirus Guy,  the Fukushu  shown in the last picture, does the picture's description mean that Pt was grafted on a sour orange root stock and then the Fukushu was grafted onto that combination ?
