This year our grass came back good enough that when we bushhog next weekend, it will be the fifth time this year.
We sprayed with 2-D-4 this spring hoping it would help with weed control. It helped some but not nearly enough.
After talking to the vet, I have concluded that we must have nettle up on the ridge and I have seen one form of pig weed.
Horses won't eat either one unless they are literally starving, but they will eat the grass around nettle or pig weed. All they have to do is touch either one to get a violent skin reaction.
Pig weed can't be killed. It has to be pulled up by hand and even then if all the root doesn't come out, it will grow back. Walking 23 acres and hand pulling pig weed on it isn't going to happen :(
We have also been overpowered this year by dallis grass. Its sticky pods and seeds attach to anything, including the my car bumper. It will leave dark sticky marks on the horses legs (much like pine sap will). If I don't get most of it wiped off, it can leave hairless spots up and down the horse's legs. Or it can dry out the spots it is stuck too and leave light marks on the hair.
So between that garbage and the midge flies deviling my Arab and one of the Walkers, I spend 8 weeks of summer treating skin issues twice a day.
Needless to say I am one of the ones that can't wait for winter. I can be sassy and say that because I retired from the OH/PA border to Middle Tennessee, so winters aren't that bad anymore :P
