Cold Hardy Citrus / Re: breeding cold hardy pomelo
« on: August 19, 2017, 10:27:10 PM »
Wonder what the cold hardiness of a Valentine pummelo is compared to other pummelo varieties.  I ask this because Valentine is not a true pummelo, it is a hybrid of pummelo and a blood orange.

I wound all cutting that I root, by scraping a line about 1 inch long at the cutting bottom.   One note, a cutting must have energy in it to root well,  weak skinny cuttings generally do not root.

I have rooted CCPP cutting after I have used the buds I needed.  Do not skimp on quality of the ingredients for the rooting medium  Oxygen is necessary for root respiration at all times, but oxygen plays an even more critical role in the initiation of new roots on a cutting.  For example, for rooting of cuttings, drainable pore space in the medium should be 45 to 50 percent.   Once the cutting has rooted drainable pore space in the medium should be about 20 to 25%.   Use a container with a depth NO less than 4 inches.  There is no ideal rooting medium, but several combinations of materials can provide a good workable medium with a drainable pore space of 40 to 50 percent.  Good quality peat and coarse perlite, or peat and ground pine bark, on a 1:1 or 1:1.5 or 1:2 basis by volume works well in propagation containers approximately 4 inches deep.  CLEAN, CLEAN CLEAN.

To prevent leggy container grown trees, put the tree outside starting when the young tree is 2" tall.   It is the bending back and forth resistance against the wind that gives a tree's trunk strength.  If you can put the tree outside than use a fan that rotates back and forth.  Don't over due it.

In both mosaics I don't think the leaves on the "pineapple" look like actual leaves.  In both pictures they look more like a spike leaf of a pineapple, and not a deciduous leaf of a tree or bush.

Mark, my greenhouse would always be about 95-F to 110-F on sunny summer days.  I would hose down the floor, and spray water from the hose in the air and on the trees in an effort to cool the greenhouse down some.   After I installed a Wet Wall cooler system it stays at 83-F even on the hottest days.

I find that quite common this time of the year.  When my trees flush new grow during the summer months, I spray the flush with a horticultural oil solution every 3 or 4 days until the leaves firm up.  If I don't, thrips and other insects quickly begin feeding on the tender growth by sucking out the juices which cause the leaves to become very crinkled.  Once crinkled the remain that way for life.  Your damage looks only in the beginning stage. My in ground trees are also grown inside a large greenhouse. .

None of the cones in the pictures that Mikkel posted have the pineapple type spiky leaves growing out of the top like a pineapple, as they are shown in the mosaic.

I have no idea what the cone of an umbrella pine (Pinus pinea) looks like, but I know the tree grows all around the city of Rome.

It has been traditionally thought that a Meyer lemon is a hybrid of a lemon and an orange, or possibly a even a mandarin.

First you ask to much of citrus, or for any fruit for that  manner.  If you want long season (almost year around) citrus you can get it from just two trees.  A Washington Navel, and Valencia orange. Valencias can hand on the tree in good shape for a long time. 

Citrus General Discussion / Grapefruit Oil
« on: August 10, 2017, 12:27:44 PM »
Global grapefruit oil market will reach US$ 378.7 Mn in the year 2022.  Grapefruit oil has a number of widespread benefits, due to which the market of grapefruit oil is gaining traction all over the world. One of the most popular uses of grapefruit oil is in the area of weight management, where it is used as a suppressant of appetite. Grapefruit oil is rich in Vitamin C, due to which it helps in strengthening the immune system of the body. Grapefruit oil also acts as an antidepressant, and helps to maintain the digestive system of the body and also aids in the body metabolism.

Citrus General Discussion / Citrus Greening Discovered In Alabama

We knew this would happen one day, we were just trying to prolong it as long as we could. Itís happened in Mississippi, South Carolina, Georgia, Louisiana, Florida, we were the only ones to keep it out of our state until now

The condensation water should be fine, sort of like using rain water..  Just don't over water the tree.  When I was In the US Navy stationed in Okinawa our commanding officer used to collect the condensation water from the air conditioner for his wife's stem iron because of it purity.

Sylvain, an amazing chart, I'll have to study the chart before I have some question.  Thanks for the post.

If a tree is to be topped, most growers top them about 28 inches.  Very soon after topping you will see side shoot growth. 

 Florida growers who have a citrus tree in their yard, can get a vial of Tamarixia wasps to release in your tree.
 Tamarixia are great killers of citrus psyllid that spreads Greening disease.

Xie Shan (pronounced She Shan) one of the earliest maturing satsuma.  In most areas the fruit is ready to eat by mid September.  As Mr. Texas wrote, Xie Shan is ready before the peel is still green.

Citrus General Discussion / Asian Citrus Psyllid Survival
« on: August 01, 2017, 05:51:05 PM »
The two major factors that have a significant impact on the development of psyllid population, and their survival, are the availability of new growth flushes for the female ACP to lay their eggs and the temperature.  In laboratory studies it was observed that approximately 50 percent of the ACP population can tolerate low temperatures at or below freezing (32-F) for two days,  These temperatures are below most citrus growing areas. ACP subjected to higher temperatures of 104-F to 114-F the survival rate decreased by 95 percent to 100 percent.  Therefor, it would appear that as temperatures increase or decrease from the optimal life temperature range of 68-F to 77-F, the rate of ACP mortality is affected.  The impact of higher temperatures have greater effect on the death rate than exposure to lower temperatures.

It took a long time for citrus to reach the Mediterranean and beyond.

Citrus General Discussion / Re: Is this Citrus Greening ?

Two possible causes for the crinkled leaves of a new flush.  The first is Citrus leaf miners.  You can look up "Citrus leaf Miners" on the Internet and it will tell you every thing you need to know. As Susanne wrote, if the damage is indeed caused by leaf miners you will see trails through the leaf where the worm mined.  The second is two insects called aphids, and thrips.  You can also see pictures of thrips on the Internet.  Thrips VERY FREQUENTLY attack the tender young leaves of a new flush of growth.  They feed by sucking the juices from the leaves which causes the leaves to become very distorted.   This damage will last for the life of the leaf (about 2 years).  I have a thrip problem just about with every new flush.  I spray a horticultural oil on the new flushes every two or three days until the leaves firm up. This stops any leaf damage, and results in a tree with beautiful foliage.  Horticultural oils are completely safe to humans and annals.  Note: : NEVER spray a citrus tree with anything during the heat of the day.  Hope this helps.
