Day

The Day avocado is a variety known for its cold hardiness and relatively small size, making it suitable for container growing. A 3-gallon container would house a young, relatively small Day avocado tree.

1. Tree Size and Maturity:

• Young Tree: In a 3-gallon container, you can expect a young Day avocado tree, typically under 3 feet tall.
• Grafted: Most commercially available avocado trees, including Day avocados, are grafted onto a rootstock. This enhances disease resistance and fruit production.
• Not Mature Size: The Day avocado tree will not be at its mature size in a 3-gallon container, which can be 15 to 25 feet tall when planted in the ground.
• Container-Friendly: The Day avocado’s smaller size makes it more suitable for container growing compared to larger varieties like Choquette. 

2. Fruit Production:

• Possible Fruiting: It’s possible for even young grafted avocado trees in containers to produce fruit, but it may take a few years.
• Type A Flower: Day is a Type A avocado, so you may need another avocado tree with a Type B flower to ensure good pollination and fruit production if not growing in Florida. .
• Fruit Characteristics: The Day avocado produces medium-sized, pear-shaped fruit with a green skin that turns yellowish-green when ripe. It has a creamy, pale green flesh and a mild flavor. 

3. Tree Care:

• Sunlight: Avocado trees need full sun, ideally 6 to 8 hours daily.
• Watering: Water regularly, letting the soil dry out slightly between waterings. Avoid overwatering.
• Soil: Use a well-draining potting mix specifically formulated for avocados or citrus trees.
• Fertilizing: Feed regularly with a balanced avocado fertilizer.
• Pruning: Prune to maintain shape, remove dead or crossing branches, and control size. 

In summary, a Day avocado in a 3-gallon container is a good starting point for growing this cold-hardy variety, particularly if you have limited space. Be sure to provide proper care, including adequate sunlight, water, and fertilizer, to ensure healthy growth and potential fruit production.
