Do you want your trees to look like this photo below?
Take a peek at DeBoer's large selection at www.deboertreefarm.com. If it is fruit trees you are looking for (this is a food blog, after all), he has those, too. Notify him by March or earlier this Spring to request special varieties that interest you. Or maybe you've heard to buzz about the aronia berry? He's hoping to supply those healthy berry bushes soon! Whatever you're looking for, you'll enjoy the drive out to the tree farm (and the prices).
