Italiangirl,
You have to harden the new trees off for the wind as well. In spring it usually gets windy at times. I would still introdude them to the sun outdoors for short periods of time
for a few days at least. Keep a check of the moisture level as well. I do the same for my garden veggie plants as well.

Depending on the size of the pots, you could end up really drying out the trees in a window. I'd put a thermometer up there and check from time to time. Can get over 90 degrees near a window in sunny weather. The combination of dehydration and heat may dessicate your new roots.
Of course the larger the root containers the less risk, cause it takes a lot longer to heat up a 4 gallon pot of soil than a 4 inch pot.
On the other hand, resist the temptation to water unless you do a 'moisture check. If you push a popsicle stem into the soil and it comes out dry, you can add water, but if moist soil holds to it, wait another day.
For a few $ you can get those moisture meters to check for better accuracy.
a bit dry is far safer than damp.
Figs tolerate dry much better than soggy.

Ciao Lou, Thanks, the wind is very important factor. I will consider this.I forget about how windy it gets around here in the spring. It can really strip a poor fig tree when they ( the winds ) are whipping.

Ciao Boizeau, Thanks for your info. I am not talking about my young new cuttings that have rooted out, they are in their own environment at the moment because they are delicate and need extra love and attention and they are doing just wonderfully. I am talking about the trees that I have which are very large and have produced well the past few years. Since this is the first year without my lights, I just needed to know about the Big boys. The Large ones are already in very large pots, I do have a moisture and temp barometer set up in the garden room where I keep it maintained to certain specifications for the figs. I just wondered about sunburn, The temperature and the humidity I already keep under control. Thanks for your imput. Ciao

I lost my tree that used to provide dappled sun to put my spring rooted plants under. I am thinking of providing a slanting tarp wall (or canopy) using four sturdy sticks in the ground. This temporary wall will be actually slanting at about 45 degrees with the top slanting toward North to give more shaded area from sun but lighted area. I hope it will work for hardening in the spring.

Oh K

I thought you had young cuttings there.
Either you have a big house or need to squeeze through that room!
One down side of keeping plants indoors is that we tend to keep the house warmer at night than is natural for outdoor plants, and that means they are using up energy at night and burning carbohydrates. If you can keep that room around 50 at night, the trees will be better off.

ottawan, yes, I have very limited shade in the back where all the veggies, figs, ect go. I remember my grandfather used to use a real large white almost mesh looking tarp that he had over many of his plants, it was huge, like a big blanket but white and almost clear, sun got through, but not intensity. This was in Italy where always the sun beat on things hard, he didn't want to get such hard sun on certain plants that he grew. Our figs were always in the full sun though. Do you know what I mean. It was lifted on polls about 10 feet above all those plants. It was probably 50ftx50ft. It was very translucent linen looking material. I can't find that here. Maybe he just made it? I wish I had something like that. I will use the back porch though and see if that helps, the back porch is on the north side of the house and only gets about 2 hours of sun in the morning, kinda shaded by the neighbors house. We had a maple tree that grew in the back, but I chopped it down because I wanted more sun for the Fig trees. It still tries to come up every spring though. I always feel bad about chopping a tree down, but there are millions of Maple trees here in Pennsylvania. Still, I could use the shade to harden off, Yes? Oh well, We will do something, I would rather have lots of sun instead of the cold shade. Ciao Ottawan and good luck. Hope it works well for you. Maggie

In hardening off I have found that the greatest damage to plants being introduced outside isn't necessarily temperatures or wind, its definitely UV radiation! You will need to harden off against UV or your plants will quickly develop bleached-sunburnt leaves.

Most of mine are still sleeping, but I did awaken two early specifically to try out the question about whether or not an early awakening really does put the plant back or if it is just a potential outcome of early awakening.

I have an ash tree that I've been wishing death upon for the past couple years. It truly is in decline (Emerald Ash Borer is most likely) but out of spite it has been holding on even after splitting 2 years ago and smoldering for almost a week at the uppermost branches early last summer. WEre it in my yard there would be no question, but it is actually just inches inside my neighbor's yard. The overhanging branches are not the primary issue, but the tendency of it to shade my garden is my issue with it.

Chills, yes, the issue of a tree shading areas where you have gardens or plants that require full hot sun is a big problem that I hope you can resolve. Figs in particular do not like shade, they love the Sun, all day! Ciao
