Perfect for urban gardening, the Tasty Red Urban Apple tree from Garden Debut produces delicious, full-sized apples on slender, vertical trees. The slender, vertical tree does well in a large pot on sunny decks or balconies and comes in several varieties, including Tangy Green, Blushing Delight and Golden Treat. The tree matures at 8 to 10 feet tall, but don’t get larger than 2 feet in diameter. When grown in full sun, you can expect to see apples in the first year as long as there are two or more varieties for cross pollination. As the tree matures, the yield increases. It’s hardy in Zones 4 to 9.
