Prunus persica 'Madison'
Madison peach is a medium sized, bright red freestone fruit. This high quality fruit has slightly fibrous, firm orange-yellow flesh that is mild and rich in flavor.Tree is hardy, vigorous, frost resistant and self-pollinating. Recommended for Northern climates. It ripens late in mid-season.
Released by the Virginia Station in 1963, Madison was found to have excellent late frost tolerance and good cold hardiness, so seems to do very well in marginal peach areas.
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.
