Thanks for asking questions.

Where are you, what is your climate?

Bay area, California.

So you have a warm temperate maritime climate, yes?

Most of the rain falls in cooler months and very little in summer, correct?




What is the soil like where it is planted? Depth? Composition?
Layering?

I do not know how to describe the soil. It is semi black (i.e.. not
sandy, if that is a technical term). I do not know about any layering
either. It all came with the house.


Perhaps you need to find out what is under your topsoil. Dig some holes,
you don't need to go down more than about 18in (45cms), and find out how far
this black topsoil extends. Just as an example, if it was trucked in and is
only 4" (10cm) deep with hardpan or clay underneath then trees (even
shallow-rooted ones like citrus) will find it hard going and it will dry out
badly in summer. You need to understand your soil if you are going to do
anything in the garden apart from guess.


Do you feed, water or spray it at all, if so when, with what?

I water it everyday.

Stop it! Very generally, when it rains in the winter don't water it at all
and if your summer is very dry do a deep watering once a week unless it
rains. Few deep waterings are much better than many shallow. Rather than
water on a schedule it is much better to check the soil moisture and water
according to need. Mulch the surface under the tree to retain water.

I also gave miracle grow for fruits sometime
(once in 15 days) with no visible effect.



Only do this during the growing season and stick to the instructions. I
don't know miracle grow, does it have trace elements in it? Citrus are
heavy feeders and may exhaust some nutrients, shortages of iron (trace
element) and nitrogen (bulk nutrient) are common.


What is the aspect? How much sun, wind and rain does it get? Is it
on potential a watercourse or a dry ridge?

What is 'aspect'? If you mean 'aspect ratio', it is about 3 ft tall
and 1.5 ft in width measured end-to-end on its branch. It is under
open sky and get plenty of sun and as much rain as you get in Bay
area. There is no watercourse or dry ridge anywhere nearby that I
know.


Aspect means the way that the garden faces, the direction, the amount of sun
and other elements that it is exposed to. How many hours of sunlight does
the orange get now?


Can you show us a picture?


Will post one soon.
