Almost all peaches are self-fertile and require no pollinators. They will set heavy crops on single trees, which need heavy and aggressive thinning early in the season for best fruit size. Maintain good vigor in peaches by pruning every year, and fertilizing moderately. Aim for 1-3 feet of new growth a year. Fertilize early in the season, so that growth is well hardened off before fall and winter cold weather.
Gloria is so new that Grandpa doesn't have a lot of experience with it yet, but he believes it has potential for northern peach areas like western Michigan where many peaches are grown.
