The ASPCA has F. benjamina listed as toxic to horses because of ficin and ficusin. I was thinking of planting some figs in and around a horse field, but I don't want to kill the horses if they do some browsing when the grass gets short, obviously. So does anybody have any experience with horses and figs? Thanks.

Ficus benjamina is the common weeping fig, the edible fig is ficus carica.  Either an equine vet or a univ. vet school with an equine program should be able to answer your question. 

From http://www.hort.purdue.edu/newcrop/morton/fig.html in reference to ficus carica:

Toxicity The latex of the unripe fruits and of any part of the tree may be severely irritating to the skin if not removed promptly. It is an occupational hazard not only to fig harvesters and packers but also to workers in food industries, and to those who employ the latex to treat skin diseases.

Thanks, I will look for a vet to ask in Cali where figs grow wild, if any vet knows it would be somebody in the South or West. I doubt our vet would know because figs are so rare here.

I sort of think that individual horses could be a problem because they all have different tastes and personalities. An electric fence inside the field would be safe as well (we do not electrify most of their fences all winter and they still don't go near them ; ) and plant larger trees than I normally would. Not this year though.

I doubt the horses will mess with the figs.  I have goats and they are the one thing they will not eat.

I cannot answer if fig leaves are toxic to horses but the converse is true.
I have read that what horse leaves is toxic to the fig plant if used the first year unless composted for some time.

Good to know goats will not eat fig leaves. I would think they would be climbing the trees to get the figs!

Good point Akram. I should test the soil to see how high the nitrogen levels are there. The site I was planning on planting is on the back side of the stalls so it may get way too much ammonia from runoff.

Make sure there is no oleander plants around them horses .
It can kill them if eaten in small amounts according to articles i have read.
Its one of the most poisonous plants one can grow in the yard.

Kids either! It amazes me that people grow deadly poisonous plants just because they look nice and do not have as many pest problems.

I feed fig leaves to my rabbits, they love it.

I have an oleander in a pot and it looks nice hmm wonder if i lay leave some leaves in the veggie garden if the wabitts would try them instead of my veggies !

Just spend extra time fussing over your oleander and those squirrels will zero right in on it  and just have to take a taste ; )
SOBs just pulled up one of most treasured cuttings and gnawed it all to hell. I am getting my babies out of this dangerous city environment tomorrow.
