I have seen Figs grown intensively with little spacing and of course also spread very far apart. If you were planting an orchard how far would you space your plants? Is anyone growing there figs closer than 10 feet apart? If so how is that working for you?

Have seen them grown at 5-6' spacing in a yard and doing fine. Commercial orchards are more like 15' spacing. You need to consider access for watering, pruning, weeding, etc. and different fertilizer regimen for close plantings. It is less about what is right, and more about properly meeting of requirements of which one you choose.

Thanks for your response!  Any insights on spacing and yields?

Hi,
It depends on the land you're planting in, climate, the varieties that you'll be planting and the pruning you'll be using.
It depends on the shape that you will use: cordon ? espalier ? tree ? bush ? wild ?
For pruned dwarfish fig trees, 6' (2 meters) should be enough.
For mowing with a machine in between, 9' (3 meters) would perhaps be better.
You could use 6' distance in the line, and 9' between the lines - this would be my choice here in my locales.
In a dry climate with cheap land, one would use a bit more of distance in between the trees.
You could use 12' distance for big trees like Panaché, bourjassotte, col de dame, ... - I wouldn't use any of those here in my locales ...
Remember that fruits need sun and heat to ripen to a good quality.
It depends of course of the age of the trees. Young trees use less space when a bigger one will need a bit more space while producing a bit more.

For the yield, once more, it depends on the strain that you'll plant, the weather damages, the bird damages, the watering, the feeding, the pruning, strains with brebas and main crop ...
To start with, don't mess up and use a smyrna strain (like Ice crystal), or a late ripening variety: Remember that you're in Zone7 ... Or you'll get nothing ...
Did you select some strains already ?

Thanks for your input.  There are a lot of variables for sure.  I have selected some varieties, right now I have Southern Brown Turkey, Celeste, Brunswick trees and I am rooting MBVS and RdB.  I want Hardy Chicago and a green variety.  The plan is to keep the trees pruned to about 7 or 8 feet tall.

It depends on the form you will grow them. I think 10-12 ft would be plenty of if you are growing them in tree form. However, I too am in zone 7a, and I would suggest bush form. This allows more chances of above-ground survival in a harsh winter. In that case I would go for 12-15 ft spacing.

Most likely I will grow bush form.  Anyone growing a fig hedge?

There are four fig trees planted in a row on a property in our neighborhood that are about four feet apart.  They are two feet from a building on one side, and the other side is about three feet from the street.  They were planted in heavy clay in an area that has been built up to be about four feet above street level.  The trees all range from eight to twelve feet in height and are very healthy.  Hope this helps.  

I just planted 200 brown turkey type figs, spaced 2ft apart, they were in 5gal pots 4-6ft tall. Also planted 100 black mission fig trees in 10gal pots, 5-8ft tall, at 3ft spacing. I want a fast dense hedge to keep the wild pigs, dogs, cats, goats, horses, humans, ect out of the yard. I'm going to try to pleaching the branches together.

Wow! That sounds really nice Figgysaid1. It would be awesome to see some pictures :) I am sure others have questions in regard to spacing in high density.

Thanks for the input Figeater. How mature are the trees? Are they growing in bush or tree form?

The trees are at least 6 years old.  They are growing freely w/o pruning of any kind, except for the street side, which is cut back severely to allow people to walk past on the sidewalk.

I'm planting my figs 15ft apart
