I have some young rooted plants in pots.Some of the have long trunks (i had cut long suckers to root).Is t better to plant them deeper than the root level meaning coverng their long trunk better or should i plant at root level.Here is a pic.   

Hi Lydios!
I planted a noid black fig deep last fall, then asked if it was a mistake. The response was that there was no problem, and that with multiple 'trunks', it would be hedge-like. Cool! Besides, you'll have good roots, and a greater likelihood of survival there's a bad freeze.
Here's a pic from a few days ago, and it has ~10 figs on it. This went from nearly dead last fall, to healthy and fruiting less than a year later.

What varieties are you growing?
What city or zone are you in?

I have 2 fig (unknown varieties - collected locally from neighbors)  grown in pot for 2 years.  Then after the last frost date in North Texas (DFW area) - I planted them in the ground.  Both - I planted about 8 inch deeper than what was on the pot.  Both leafed out fine and very vigorous growing now.  I think - somewhere I read - you can plant figs few inches deeper to make it bushier looking.  

Thank you for the replies guys. 

Where in Greece are you from? My wife's family is from Rhodes south side of the island

Sohelz--it makes sense that planting the fig tree deeper would give it a bigger root system and bushier growth. I suspect this is true of many plants that root readily from the stem.
Lydios and Sohelz--do you have pictures of your trees, leaf and fruit?

I kind of envy these growers in warm areas where many plants grow so easily, although I realize that any zone will have its advantages and disadvantages. The tulips and hyacinths that grow effortlessly here in zone 6 are nearly impossible for my trading buddies in more tropical areas...it doesn't stop me from trying to grow bananas andthe like....

,

my inground trees were planted with the top of the root ball 12'' underground. this protects  from both cold n drought.
the buried trunks have grown roots pllus branches. people call these suckers but they are just branches.
