Peters is used dissolved in water and applied to the root zone.

In my opinion Peters 25-5-15 is the very best fertilizer for citrus .  The bag does give a rate for use when used to apply to containers as well as in ground.  You will find the amount for Small Volume Measuring on the bags lower left hand corner.   The rate for your container is 1 teaspoon of Peters per gallon of water.  This will give your tree 225 PPM N..

What Lebmung wrote, cold can be a possibility in certain sections of the country, but not in an area such as San Diego. As to the fertilizer, I personally would not use it.  Citrus are heavy feeders, more so than many other plants.  I use a fertilizer with a NPK percentage of 25,5,15.  Meaning 25%N, 5% P, and 15% K.  Note: this is a 5-1-3 nutrient ratio fertilizer.  According to the text book Citrus, and University research,  this is the ratio that citrus absorb nutrients.  Lastly, besides the low level of the elements NPK, many of the nutrients in your fertilizer example are oxides, instead of being sulfates.

Using a water soluble fertilizer and Osmocote will not cause a problem.  Using both types of fertilizers is actually a good nutrition program, as it reduces the highs and lows of available nutrition to your tree.  As it now stands your tree is nutrient deficient.  The best to you and your tree.

The discoloration of your tree's leaves are not due to seasonal changes.  It certainly looks like deficiencies of iron and nitrogen.  The deficiency leaf symptom for iron is:  NEW leaves with green veins on otherwise a yellow leaf.  This deficiency can be caused either by high pH  or the shortage of minerals.  The leaf symptoms for a nitrogen deficiency is: Totally yellow leaves with no variation of color, or yellow/orange veins with some green out on the leaf sides.  Nitrogen is highly soluble, and thus is quickly leached from the medium with watering. For a container grown tree, growing in a rapidly draining medium, the tree should be fertilized at the very least once a month.  Once ever couple weeks would be much better.  Locate a water soluble fertilizer with higher levels of nitrogen and potassium and a lower level of phosphorous. Be sure the fertilizer also contains trace minerals.  It is difficult to see your tree's medium, as it is covered with dead laves.  What is the makeup of the medium mixture that the tree is presently growing in?

In my greenhouse I have two large propane heaters.  One is set to come on when the greenhouse temperature falls to 55-F.  The second propane heater is set to come on when the greenhouse temperature falls below 40-F, therefore the second heater  only ignites if the primary heater fails.  I have used this system for 30 years.  Both heaters are vented to the outside. I have never ever had a problem with low oxygen.

Brian, the high CO2 should greatly help the growth of your trees.  Commercial greenhouses  install CO2 generators for exactly this additional growth,

Citradia, looks like you have to build a higher frame for your Changsha.  I agree with lebmung, you did an exceptional job with your seedling Changsha.

Citrus General Discussion / Re: Lemon tree help -yellowing leaves
« on: December 01, 2019, 01:34:26 PM »
It is easy to determine the difficulty your tree is having.   No fertilizer all summer is not a good situation. without fertilizing the tree certainly will become deficient of the vital minerals required, thus is incapable to producing any growth., Using an organic fertilizer in a container, such as Citrus tone, is also not a good situation.  Organic fertilizers require microorganisms to break down the organic fertilizer to make it usable to the tree.  Container mediums do not have the microorganisms required to accomplish this.  Be careful purchasing Miracle grow as the product is different in different parts of the country.  A 50/50 mix of Turface and Miracle Grown Garden Soil is also a very good medium for container culture.  Miracle Grow Garden soil is different than plain Miracle grow  potting soil.  Also a 5-1-1 or a 5-2-1 mix is a good medium. I would recommend using a conventional fertilizer with higher levels of nitrogen and potassium and a smaller concentration  of phosphorous plus with trace minerals. Good luck to you and this tree.

To try to get a hold on the situation.

How long has the tree  peen planted in this same medium?
What fertilizer are you using to feed this tree?
How often do you fertilize the tree?

Cold Hardy Citrus / Re: Kulu lemon
« on: November 28, 2019, 10:12:47 PM »
From looking at Ilya11 picture there seems to be very little pulp, and a lot of thick peel.  Therefore, its use as a lemon is greatly reduced

I pick them as I need them.  Anywhere from 2 weeks to a month or so.

Lebmung,  may or may not kill 100% of the cottony cushion scale (CCS) but at this point giorgosgr's tree is heavily infested with the insect. A hard direct in line spray with his hose will certainly greatly reduce the highly damaging attach that his tree now has.

Also I found this on the University of California's web site about  imidacloprid.

Do not apply imidacloprid (Merit or Bayer Advanced Citrus Fruit and Vegetables) for cottony cushion scale control. Although imidacloprid has scale insects listed on the label, it doesnít kill cottony cushion scale. To make matters worse, imidacloprid is very toxic to vedalia beetles. The beetles are poisoned when they feed on cottony cushion scale that have ingested imidacloprid. Cottony cushion scale outbreaks have been observed following use of this insecticide because the vedalia beetles were removed and the insecticide didnít control the pest

Citrus General Discussion / Re: Shiranui and Tahoe ripening?
« on: November 26, 2019, 06:10:05 PM »
In Japan Shiranui (Dekopon) is harvested between December through February.  Here in Colorado (greenhouse grown) the fruit on my tree began to color up 3 weeks ago, and today are fully yellow.  I ate one several days ago, and it was good, but not as sweet as it should have been.  I am going to leave mine hang for a while, and taste again in a week.  Know that the Japanese growers let them set after picking for 20 to 40 days wrapped in paper to let the acids reduce and the sugars increase.

Benton is frequently used as a rootstock for lemons.  One of the requirements for a commercial rootstock variety is that the fruit produce adequate amount of seeds.

I have an in ground Dekopon tree in my greenhouse.  The greenhouse is at 5,440-ft  elevation (1,658 M).  Day  temperatures are around 70F during the winter when the sun is out, and the temperatures is set to maintain a 55-F night temperature.  Under these conditions the Dekopon's are now most completely yellow.

As Spaugh wrote, put one of those brass adjustable nozzles on your hose and adjust the nozzle  to the straight water spray, and you can blast them from the tree.  Make 3 to 4 follow up sprays.  Keep an eye out for any further build up and blast them as quick as you see them.

lebmung, you don't cover your seeds with a layer of the medium?

Kumin, good post.  100 years of mono cropping, plus keeping Florida citrus grown bare of vegetation as taken its toll.  Your post make sense.

Dihvac,  California produces citrus cultivars that are for eaten out of hand.  Florida growers dominantly produce,citrus cultivars for juicing and not for eating out of hand.  Therefore, most of the eatable citrus in Florida are California oranges.

As written above citrus seeds do not transmit HLB, also  none of the true virus diseases (Tristeza, psoriasis ect.) . are also not transmitted through the seed.

I used to live on  Okinawa and never heard of this cultivar.  Let us know from time to time how your Shiikuwasha is doing, I would be interested.

I have been hearing a lot about the use of rice hulls in general nursery culture of bedded plants.  I am very interested in experimenting with rice hulls in the cultivation of citrus trees.  Doing tests such as the length of time before the hulls begin to deteriorate, root zone aeration, etc.
