how did you come up with 3 cans of water..???

take a tablespoon and dig a 3 to 6 inch hole.. is the ANY moisture in the root zone??

if not..water until ALL the media is moist..

did you premoisten it.. before you put the plant in it???

the plant is severely stressed.. NEVER fert a stressed plant... nor a recent transplant..

if you can.. protect form sun.. until the roots start pumping water ..

flowers are the first things sacrificed .. at least the leaves havent burnt yet.... so increase watering before you lose those...

the fact that the boards of your barrel are not tight together.. means the wooden barrel has not sealed due to moisture... and the barrel itself might be wicking moisture form the media...

next time.. premoisten your media on repotting.. and water to maintain said level of moisture....

I see some  problems on how you say to  do things   because I learned to master cla  without adding anything. I've  always  had to grow  citrus in flowerpots  and when it came to transplanting  I learned the hard way how to grow everything in clay  from  a garden to  houseplants an  prickly pear cactus   yucca plants and citrus seeds  you add too much  water    you need to get   a balance   and when  the leave show burning it's offten from mineral salts build up

Agreed that the only way to know if watering has been adequate or excessive, is to dig down at least a few inches (away from the central stem) to check on soil moisture. Does the pot have adequate drainage holes? At each watering, enough should be given to start draining out the bottom; then no more until the upper soil levels are drying out.

Prepared soil mixes are often too heavy and poorly draining, and can get soggy in bottom layers. I generally amend them at least 1:1 with something lightweight like Pro-Mix.

Make sure there are no insect pests lurking under leaves and on stems. Citrus can be prone to scale infestations.

         The only things I added was   tea bags that I opened and applied to the top of the soil and  liquid   fertilzer  and may be  some small amount of a commercial polutry  manure fertilizer  to  the surface

When you water, water with at least three gallons of water. That pot looks too big though. It may stay wet too long resulting in root rot.

I bet you are using Miracle Gro soil for (one marked for Citrus). Miragro Gro soils are high in peat moss and bake in the sun outdoors. Then, the soils become very hydrophobic and resist any water retention. You may think you are watering, but I bet the soil is bone dry. Also, I agree with the above poster, your container is massively oversized for the size of the plant.

 James    how much  water are u    using  the problem  with   peat it can take hours. To  absorb  all the water   it is many  times slower than clay is at least asorbs  fast   this is my experience with pear      I hope  your root system  is large   for  the container  don't  make your tree look too healthy

Why are you using an organic fertilizer in your potted tree?

Why not a good all around readily available one once you get the right mix in action?

i just applied citrus tone for the first time to my containers maybe 2 weeks ago when fruit was setting. citrus tone was recommended several times on reddit. is it no good for container trees?
