What are Cherry Blossoms (Genus Prunus)?

Cherry blossoms are the flowers of many trees of genus Prunus, particularly the Japanese cherry, Prunus serrulata, which is also known as Sakura. These ornamental trees are celebrated worldwide for their profusion of delicate, showy flowers that bloom in early spring, heralding the arrival of warmer weather. Cherry blossom flowers are typically pink or white, and varieties range from single-petaled to double-petaled, with varying shades and forms. While some Prunusspecies produce edible cherries, ornamental cherry blossom trees are primarily grown for their floral display. They are deciduous trees, meaning they lose their leaves in the fall. Cherry blossoms are deeply ingrained in Japanese culture, symbolizing the fleeting nature of life and the beauty of spring. They are cherished for their spectacular spring blooms, elegant appearance, cultural significance, and ability to thrive in urban environments, making them a beloved choice for gardens and landscapes around the world.

Are Cherry Blossom Trees Good for Outdoor Pots?

Yes, certain types of cherry blossom trees are well-suited for outdoor pots and container gardening. Dwarf cherry tree varieties and those with a naturally smaller mature size are best for growing in containers. Growing cherry blossom trees in pots offers several advantages:

• Space Saving: Allows you to enjoy cherry blossoms in small gardens, patios, balconies, and other limited spaces where planting in the ground is not feasible.
• Portability: Potted cherry trees can be moved to different locations to optimize sunlight exposure, provide shelter from harsh weather, or for aesthetic arrangement.
• Control over Soil Conditions: Container gardening allows you to provide the specific soil type and drainage that cherry trees prefer.
• Manageable Size: Confines the root system, helping to keep dwarf cherry trees smaller and more manageable than they would be in the ground.

Ideal Growing Conditions for Cherry Blossom Trees in Pots:

• Types of Cherry Blossom Trees for Pots (Dwarf Varieties): Not all cherry blossom trees are suitable for pots. Choose dwarf or semi-dwarf varieties that are grafted onto dwarfing rootstock. These varieties are bred to stay smaller and are more manageable in containers. Some excellent choices include:

  • ‘Kojo-no-mai’ Cherry (Prunus incisa ‘Kojo-no-mai’): A very dwarf variety, reaching only 6-8 feet tall and wide, known for its zig-zag branching and delicate pink flowers. Excellent for small pots and balconies.
  • ‘Fuji Cherry’ (Prunus incisa ‘Fuji Waterfall’ or ‘Pendula Nana’): A dwarf weeping cherry, reaching 6-10 feet tall, with cascading branches and pink flowers. Beautiful in elevated planters or large pots where its weeping form can be showcased.
  • ‘Royal Burgundy’ Cherry (Prunus serrulata ‘Royal Burgundy’): A dwarf cultivar of Kwanzan cherry, reaching about 15-20 feet, with deep burgundy foliage and double pink flowers. Requires a larger pot but offers striking foliage color in addition to blossoms.
  • ‘Pink Perfection’ Cherry (Prunus ‘Pink Perfection’): A compact, upright variety reaching about 15-20 feet, with double pink flowers. Suitable for larger containers and offers a classic cherry blossom look in a smaller size.
  • ‘Accolade’ Cherry (Prunus ‘Accolade’): A small, vase-shaped tree reaching 20-25 feet, but slower growing and more manageable in a pot than full-sized cherries. Features semi-double pink flowers.
  • Gisela 5 or Gisela 6 rootstock: When purchasing any cherry blossom tree for a pot, ensure it is grafted onto a dwarfing rootstock such as Gisela 5 or Gisela 6. This is crucial for keeping the tree size manageable in a container. Check plant labels or ask nursery staff for rootstock information.

• Light: Cherry blossom trees need full sun to thrive and bloom profusely. They require at least 6-8 hours of direct sunlight per day. Choose a sunny location for your potted cherry tree, such as a south-facing patio or balcony. Insufficient sunlight will result in poor flowering and weak growth.

• Soil: Cherry blossom trees need well-draining soil that is also fertile and retains some moisture. Use a high-quality potting mix amended with compost or well-rotted manure to improve fertility and drainage. Avoid heavy clay soils or mixes that retain too much water, as cherry trees are susceptible to root rot in soggy conditions. A slightly acidic to neutral pH (around 6.0-7.0) is ideal. Good drainage is paramount for cherry trees in pots.

• Watering: Cherry blossom trees in pots need regular watering, especially during the growing season and when they are blooming. Water deeply when the top inch of soil feels dry. Water until water drains from the drainage holes. Avoid letting the soil dry out completely, but also avoid overwatering and soggy soil. Check soil moisture regularly, especially during hot, dry, or windy weather, and adjust watering frequency accordingly. Reduce watering slightly in fall and winter when the tree is dormant. Consistent moisture is important, especially for young trees and during bloom time.

• Temperature: Cherry blossom trees are cold-hardy and require a period of winter chill to bloom properly. They can tolerate cold temperatures down to USDA zone 5 (and sometimes even colder, depending on the variety). However, when grown in pots, their roots are more exposed to cold, so some winter protection may be beneficial in very cold climates (zones 5 and colder). This can include wrapping the pot in burlap or bubble wrap, or moving the pot to a sheltered location like an unheated garage or shed during the coldest periods. Cherry blossoms bloom in early spring, after a period of cold dormancy. They prefer moderate spring temperatures during bloom time. Avoid placing pots in overly exposed windy locations, which can desiccate trees in winter and damage blossoms in spring.

• Fertilizer: Cherry blossom trees benefit from regular fertilization, especially when grown in pots where nutrients can leach out more quickly. Fertilize in early spring as new growth begins, and again after flowering. Use a balanced fertilizer (e.g., 10-10-10 or 20-20-20) or a fertilizer specifically formulated for flowering trees and shrubs. Follow package instructions for application rates. Avoid over-fertilizing, which can lead to excessive leafy growth at the expense of flowers, and can also create salt buildup in pots. A slow-release fertilizer can also be incorporated into the potting mix at planting time.

Choosing the Right Pots for Cherry Blossom Trees:

• Suitable Pot Types: Choose large, sturdy pots made from durable materials that can withstand the weight of a mature tree and the elements. Good options include:

  • Large Resin Pots: Lightweight, durable, weather-resistant, and available in various styles mimicking terracotta or stone. Excellent choice for cherry trees due to their durability, lighter weight than terracotta or concrete, and good insulation for roots. Choose high-quality, UV-resistant resin pots.
  • Large Plastic Pots: Inexpensive, lightweight, and retain moisture well. Choose thick, durable plastic pots that are UV-resistant and can withstand outdoor conditions. Darker colors can heat up more in sun, so lighter colors may be preferable in very sunny locations.
  • Heavy Terracotta or Stone Pots: Classic and aesthetically pleasing, but very heavy and can dry out quickly. Terracotta and stone pots can be used, but require careful attention to watering and may be difficult to move once planted. Choose very large sizes to provide adequate root space and stability.
  • Wooden Planters: Attractive and provide good insulation for roots. Ensure wooden planters are well-constructed and lined with plastic to prevent rot and improve moisture retention.

• Drainage: Excellent drainage is crucial for cherry blossom trees in pots to prevent root rot. Ensure your chosen pot has large drainage holes at the bottom. Adding a layer of gravel or pot shards at the base of the pot can further improve drainage, especially for very large, deep pots. Use a well-draining potting mix. Elevating pots slightly on pot feet can also improve drainage and air circulation around the base.

• Pot Size: Choose a pot that is appropriately sized for the dwarf cherry tree variety you select, and allows for future growth. Start with a pot that is at least 20-24 inches in diameter and depth for dwarf varieties like ‘Kojo-no-mai’ or ‘Fuji Cherry’. Larger varieties like ‘Royal Burgundy’ or ‘Pink Perfection’ will eventually need even larger pots, 24-30 inches or more in diameter and depth.

  • Initial Pot Size: When planting a young dwarf cherry tree, start with a pot that is at least 20-24 inches wide and deep.
  • Repotting: Cherry trees in pots will eventually become root-bound and need repotting into larger containers every 2-3 years, or as needed. When repotting, increase the pot size by only a few inches in diameter each time. Mature dwarf cherry trees may eventually reach their maximum pot size and will no longer need repotting, but will require regular root pruning to maintain them in the same container size (see “Root Pruning” below).
  • Depth: Ensure pots are at least 20-24 inches deep to provide adequate root space for dwarf cherry trees. Deeper pots are better for root development and stability.

• Color and Style: Choose pot colors and styles that complement the cherry blossoms and your outdoor décor. Neutral pots in gray, white, black, terracotta, or natural stone tones can provide an elegant backdrop and highlight the delicate pink or white flowers. Ornate or decorative pots can add a more formal or artistic touch. Consider the overall style of your patio or garden and choose pots that enhance the aesthetic.

Essential Care Tips for Thriving Cherry Blossom Trees in Outdoor Pots:

• Watering: “Water Deeply When Topsoil is Dry, Avoid Overwatering”. Water deeply when the top inch of soil feels dry. Water until water drains from drainage holes. Avoid letting soil dry out completely, but also avoid overwatering and soggy soil. Check soil moisture regularly and adjust watering based on weather conditions.
• Sunlight: Provide Full Sun (6-8+ Hours Daily). Place cherry blossom pots in a location that receives full sun for best blooming and healthy growth.
• Fertilizing: Fertilize in Early Spring and After Blooming. Fertilize in early spring and again after flowering with a balanced fertilizer or flowering tree/shrub fertilizer. Follow package instructions. Avoid over-fertilizing.
• Pruning (Minimal Annual Pruning): Cherry blossom trees require minimal annual pruning. Prune lightly in late spring or summer, after flowering, to remove any dead, damaged, or crossing branches, and to maintain shape. Avoid heavy pruning, which can reduce flowering. Focus on maintaining good air circulation within the tree canopy.
• Root Pruning (Every 2-3 Years for Mature Potted Trees): As cherry trees mature in pots, they may become root-bound. To maintain them in the same container size and prevent them from becoming overly root-bound, root prune every 2-3 years when repotting or in early spring. Carefully remove the tree from the pot, and using sharp, sterile pruning shears or a root saw, prune away about 20-30% of the outer roots around the root ball. Repot in fresh potting mix in the same pot or a slightly larger one if needed. Root pruning helps to rejuvenate the tree and encourages healthy growth in a container.
• Pest and Disease Control: Cherry blossom trees can be susceptible to certain pests and diseases, such as aphids, spider mites, scale, borers, leaf spot, and blossom blight. Monitor regularly for any signs of pests or diseases. Treat promptly with appropriate insecticidal soap, horticultural oil, neem oil, or fungicides if necessary. Good air circulation, proper watering, and fertilization can help prevent many pest and disease problems.
• Winter Protection (In Cold Climates): In USDA zones 5 and colder, provide some winter protection for potted cherry trees. Wrap pots in burlap or bubble wrap to insulate roots, or move pots to a sheltered location like an unheated garage or shed during the coldest periods. Water sparingly during winter dormancy, only enough to keep the soil from completely drying out.
