Starting Osage is really easy.
Put the hedge apples in a 5 gallon bucket and fill so the water is at least 2 to 3 inches over the top of them.
Place you bucket in some place without any heat allowing the bucket to freeze and thaw until next spring.
You should have a soft mush by next spring. Add water to the bucket and then using something like a baseball bat or whatever will work pulverize whatever is in the bucket making a slurry.
Now dig a shallow trench and pour your slurry along the length of your trench and cover with soil.
Keep it watered and you'll have more Osage saplings than you'll know what to do with.
In years gone by that was how Texans built fence..lol, Head high and hog tight!
