Sweetheart Cherry Info: Can You Grow Sweetheart Cherries At Home?
Dwarf Sweethearts are a type of cherry tree which grows naturally in the temperate zone from northern Europe to North America. They have small flowers with white petals and red seeds. Dwarf sweethearts are very popular because they produce large fruit, but not too big that it will spoil quickly. They require little care, so they make great houseplants or even indoor plants.
The name “sweetheart” comes from their resemblance to a woman’s face. Some varieties grow up to 10 feet tall and weigh over 1,000 pounds! Their leaves are alternate, wavy and elliptic; some have multiple leaflets. These types of cherry trees do well in full sun and shade.
They prefer moist soil, but don’t mind standing water during dry periods. They like bright light, but don’t need much.
They are hardy to USDA Zones 8 through 11 and resistant to powdery mildew. They’re tolerant of poor soils and require no special fertilizers or pesticides. Sweethearts are drought tolerant, but they do best when given plenty of moisture year round. When grown indoors, they thrive in temperatures between 60°F – 80°F (16°C – 26°C).
Stella cherry trees (Prunus avium) have large flowers and small oval leaves. They grow well in temperate climates, but rarely survive winters without protection in colder areas. Stella cherries can reach heights of 20 feet tall and 15 feet wide. They bear fruit early, in about 3 years, and continue bearing fruit for 5 to 10 years.
Stella cherries grow best in full sunlight and are not picky about soil types. They don’t like poorly drained areas and will not grow in waterlogged soil. These trees can be grown in containers: just keep the soil moist, but well drained. They prefer daytime temperatures between 60°F – 80°F (16°C – 26°C) at nighttime, 55°F – 60°F (13°C – 16°C).
Stella cherry trees are self-fruitful and will not need another tree for pollination.
