Here is a pic of my first inground success, a Sal's (Gene).  This is a tree received late 2014 as a successfully rooted cutting.  Last May I planted it inground beside my above ground pool for protection.  It misses some sun due to shading from the adjacent arborvitae, probably not in full sun till 11 AM.  It grew rather slowly initially last year, and did not put on figs till late.  They were kind of bland but were ripening in 2nd half of Oct, rather late here.

I winterized it by surrounding it with a 5ft tall wire cage, pruning back to a basic frame not over 3ft tall, filling the bottom 18 inches with large pine bark mulch chunks, then putting plastic bags full of leaves around loosely the top branches, inside wire cage.  Whole thing then covered with large tarp.  I uncovered the fig plant in mid May, long after my stored potted figs were brought out.  At that point it was starting a few 1 inch long shoots.  There was die back of about 1 inch on the two branches closest to the edge of the wire cage, likely not enough insulation for those tips.

Now with minimal fertilization this is growing like mad - almost 5 ft tall at peak - and has a large number of figlets on it - many more than any of my potted figs that are a year older.  Some of the potted plants are a couple weeks farther along in the way of fig development.  Encouraged by this success I have planted 6 more in ground - MBvs x 2, Adriatic (JH), BryantDark, Hardy Chicago and Salem White - the Salem White and a MBvs are going to be trialed along a low cordon.  If this is successful in giving a large number of figs from each in the future, I will likely transition many more to inground, except for those that require a longer growing season, and perhaps a potted plant or two of early varieties like RdB, Lattarula, Florea to have a slightly earlier harvest.

I believe the large pine bark chunks provided good drainage for any moisture inside the base of the cage while protecting the trunk's bottom 1.5 ft very well.  I would not be surprised if a really severe winter could damage the branches just protected by bagged leaves and tarp.  We will see!

I have one from Switzerland, can't get a clone from it or I would leave it uncovered to see if it makes it, the bark is very hard, tried so hard, no luck Had a crack at the base  which I made when I bend it over two years ago and last winter I cut it down, and covered it. It's growing back, had a lot of old wood stock but zero luck, I have given some from spring cuttings to a buddy who did root it, even tried to air layer it with no luck It did get down to minus 20 for two days here where I live in CT. I think it may be the cold hardiest, because of the hard time of have of getting to root it. Got 3 new shoots coming hoping I get one with some root, then I'm sure I can make a clone Have other figs, which grow like weeds when I clone them not this girl Here's a  pics of the figs

Well, that's my aim to be able to have one here in the ground like that too, I even gave about 8 old wood cuttings to a guy who owns a huge garden center that ell fig tree he tried no luck here is the type I have

THAT IS MINUS 20 F FOR TWO DAYS i'm in the coldest part of my town Southbury CT. 06488

I'll have to put pictures up of the larger, in-ground trees, but here's the in-ground nursery as of this morning.  -ER, zone 7
 

Wow, the fig nursery looks great FF. Thanks for sharing

Very nice trees everyone!!

Hi all,
here are pictures of some of my in ground fig trees:
Ali Pasha, Black Cartagena, Dottato, Michurinsk-10,
Precose de Dalmatie, Ronde de Bordeaux, White Adriatic.
  

Here's the latest of my Celeste. It's a beast at 6' tall by same amount wide. The Spanish mission next to it looks the same. This is the optimal fig tree shape ... Nice and full. It's trees like these that make the inground effort so worthwhile in cooler zones. Nothing like a robust inground fig tree in non-accommodating climate.
