Answer: I hope you mean under four feet, not under four inches! Low-bush blueberry cultivars grow only 1-2 feet tall but the fruit is plentiful, most bushes producing 1-2 pints of berries per year. Lowbush blueberries are extremely cold tolerant. Blueberries have a reputation for being particular about soil, demanding a low (or acidic) pH. Amend the soil with lots of peat moss and add sulfur if a soil test shows it is above 5.5. Blueberries are self-fertile but produce better where there is a second variety grown. Try Brunswick, Tophat or Bloodstone in your garden. There are many dwarfing rootstocks used for peach trees. While the branches remain small, the fruit is normal size. You're in USDA gardening zone 7 and can grow Early Redhaven, Golden Jubilee, Newhaven and Ventura, among others.
