It used to have train tracks going across it, so there was a hill of cinders with a couple of ditches next to the cinders, and basic disrepair meant that the grass was infested with poison oak. *shudders*
So. We had it leveled (yay, heavy machinery! XD) and planted a rye mix so that it could be made into pasture. Our old pasture was horribly depleted from years of horses grazing on it with no rotation, so the pasture was planted as well.
And now, almost a year later, we have GRASS. Eeee.
(I've had to lead them through that gate when they get scared for whatever reason. That is not an activity for the faint of heart.)
Founder, for the uninformed, is NOT good. Colletta has had it at least once (a mild case, but still) and while it can be cured/dealt with, once a horse has it they become prone to it in the future.
