Citrus General Discussion / Re: Is horticultural oil safe for citrus
« on: August 11, 2018, 04:50:21 PM »
Sylvain, thanks for your clarification on neem oil as a citrus spray.  Like I wrote, I have never used it. 

Mtlgirl, I would be very cautious spraying HO or anything if the tree's flowers are opening. I would not foliar spray while the flowers are open or even opening.  By the way does Mtlgirl stand for Mountain girl?

Ilya11, your a treasure.

Vlad, actually I have never used neem oil even once.  I have nothing against neem oil, I suppose it works well.  Using HO, I only have to purchase one chemical.  HO provides excellent results against spider mites, aphids, mealy bugs,  scale, and white fly eggs.  I suppose neem oil would work just as well, as it also has a good reputation.  I just do not like the smell of neem.  Either one could well be used.

Mtlgirl,  If the flowers are still tightly closed, a spray with a good horticultural oil will not be a problem.  However, NEVER EVER foliar spray anything when a citrus flower has opened.  I have never heard of the two HO oils you mentioned in your above post.  I use one called Ultrapure HO.  I use it at the rate of 40 grams HO per gallon water.  The best to you and your trees.

gnappi, I don't know about the red lime growing in Florida personally, but I do know various citrus cultivars never fully color up when growing in Florida. Give your tree a few years, and the tree should settle down. Foliar spraying the tree with low biuret urea approximately 1.5 months before the expected flowering date will greatly help a lot, both with the size of the crop, and also fruit retention.

Yes, your tree seems to be old enough to bear and keep fruit. Of all the fruit on the tree, what percentage of the fruit is discarded?   All citrus trees, even 25-year old trees discard fruit.  Once near the beginning of fruit set (small fruitlets) and again  at what is called "June Drop".  During June Drop the fruit size are larger. There is also a post harvest drop period.  All three are very normal and common .

How old are your trees, and what percent of the crop is being discarded?

Nice looking trees TFN

Citrus General Discussion / Re: Xie Shan in a pot?
« on: August 07, 2018, 02:40:13 PM »
I have two Xie Shan satsumas, both grafted on Flying Dragon. The oldest of the two is approximately 6 years old. It is a container tree growing in a 15-gallon container. The medium is Miracle Grow Garden Soil mixed with large sized perlite. The fruit matures in late September, and has always tasted rather good from the first fruiting, however each year the taste improves. Xie Shan, even in the ground never gets to what one would call a large tree, but as a container plant grafted on FD it will always be a quite small tree.

Citrus General Discussion / Re: Spider Mites

I use Ultra Pure Horticultural Oil, for spider mites, aphids, white fly and Mealy bugs.  The sprayer I use is a Solo sprayer.  Actually spider mites can be killed with just a strong water spray.  It might take 2 or 3 spays to accomplish the job. 

Cold Hardy Citrus / Re: Long term cold hardy citrus breeding project

Kishu is indeed a good tasting cultivar.  I used to have a kishu tree, but I removed it to plant another cultivar.  The main problem with kishu is that they are a such a very small fruit.  I also have a Page fruit, great for juicing, but it is also a small fruit, but larger than Kishu.

The common method is simply tasting a fruit every now and then as the ripening period is nearing.

SoCal2Warm thanks for the post.  I'll have to spend some time looking it over.  Appreciate your kindness.

Citrus Buy, Sell, & Trade / Re: WTB Finger Lime Tree
« on: July 31, 2018, 09:34:47 PM »
You can purchase Finger Lime trees (red or green) from Logees on line.  Also from other nurseries.

Lory nice seeing you on the forum again.  Question, are the leaves of concern from a newer flush? New growth leaves have a higher transpiration rate than mature leaves, thus loose water to the atmosphere at a higher rate.  What daytime temperatures occur at this time of year in your area.

Brain, Looking at the variegated Minneola tangelo  that you planted in the greenhouse soil, I would equate its size to a 2 year old tree that has been growing in the ground from its beginning. .  The University of Florida's fertilizer recommendations for an in ground tree of that size and age is that it should be fertilized 5 times per year.  When I first planted citrus in my greenhouse's ground, I fertilized frequently as I did when the tree was growing in a container.  The outcome was weak spindly growth.  Now I fertilize using Jacks 25-5-15 five times a year for new trees, 4 times a year on 3 year old tree, and 3 times a year on all trees 4 years and older.

Cold Hardy Citrus / Re: Yuzu - Not branching

Indole-3-acetic acid (IAA) is a major auxin produce by citrus trees. IAA controls a citrus tree's growth by cell enlargement and cell division. IAA along with cytokinin (another growth hormone) controls both apical dominance and its correlative bud inhibition. In apical dominance, growth of the apical bud inhibits the growth of all the lower lateral buds (Shoots) below the apical bud by releasing the auxin IAA and sending the auxin down the shoot past all the lateral buds.. Apical dominance results from the relative amounts of IAA, which moves down the shoot to the lower lateral buds and inhibits the synthesis of cytokinins in the lateral buds, thus inhibiting  their development and branching.  Removing the source of IAA by removing the apical bud decreases the IAA concentration moving past the lateral buds, allowing cytokinin biosynthesis to proceed and lateral buds to undergo bud break and grow out into new shoots (branches) and flowers.  Cutting off the dominant apical bud removes the source of IAA and thus causes growth of the lateral buds.  Many growers cut the apical bud at approximately 30 inches +-.  Once this is done the tree should soon start to show side growth. You can read about this process further in the Citrus Production Manual.

Citrus General Discussion / Re: Is this iron deficiency?
« on: July 24, 2018, 09:40:19 PM »
Iron deficiency symptoms on a citrus tree, shows up on the tree's new leaves as you have written.. Further, the symptoms for iron identification is green veins on otherwise  yellow leaf.  However, in your tree's case, if it is deficient in iron, the deficiency is very slight indeed.. After the recent past history of this tree, it could be caused soil pH, or the highly wet soil.

Bryan, now that the tree is planted in the ground, know that the tree's fertilizing schedule will be MUCH different than when it was a container plant.

During the first few years, apply fertilizer to young trees to stimulate vigorous growth of leaves and branches that will become the framework of the mature tree.  Beginning about 2 weeks after planting, frequent light applications of fertilizer should be made approximately every 6 weeks.  Fertilizer should not be applied between October 1 and February 1 for the first year or two, most especially in colder regions. The goal of the fertilizer program for young fruit bearing trees is to continue to stimulate vigorous growth of leaves and branches that may compete with early fruit production.  After the tree has become established, the goal will be to replace nutrients removed by the fruit and to provide enough nutrients to sustain continued tree growth. Many different fertilizers formulations are available for use on dooryard citrus trees. In general, the numbers on a fertilizer bag refer to the percent of nitrogen, phosphorus and potassium plus other secondary and micronutrients.  For example if the numbers 8-8-8 were listed on a fertilizer bag it would contain 8% nitrogen, 8% phosphorus and 8% potassium. Other nutrients like magnesium, copper, and boron may also be listed.  This type of fertilizer would be ideal for a nonbearing young citrus tree.  Higher analysis, mixed formulations such as 10-10-10, 12-12-12, or 15-0-14 are used on mature trees.  A 1 year old tree should be fertilized 6 times a growing season. A 2 year old tree should be fertilized 5 times per season. Three year old trees  4 times per season. Four year old trees and older fertilize three times a year.   For young trees, apply fertilizer uniformly in a 3-ft. diameter circle around the tree. As the tree becomes older, the area fertilized should be enlarge as the root system expands. As a rule of thumb, fertilize an area twice the diameter of the tree canopy.  Care should be taken to avoid root or trunk damage by uneven placement or mounding the fertilizer against the trunk. Purchase real fertilizer for your tree. Personally I would not use fertilizers such as  Dr. Earth and Alaska Fish fertilizer, your tree needs a real fertilizer.  Just looking at the tree it is quite easy to see that the poor thing is struggling to find some food to live on.  The best to you and your tree.

LionKing, you need to feed your tree with real fertilizer.  Citrus absorb nutrients in a 5-1-3 ratio, meaning for every 5 parts nitrogen, the tree will also absorb 1 part phosphorous and 3 parts potassium.  From my experience, you can throw away "Superthrive", its pretty much worthless. Citrus are heavy feeders, requiring more nutrition than many plants.  Find a fertilizer with a formula that is higher in nitrogen and potassium that also  contains trace minerals, and feed your tree 4 times during the season.  You should have started a good fertilizer program for your tree last March.  You are starving the poor tree. Good fortune to this trees.
