Plum – Bluefree – Prunus domestica

The plum (Prunus domestica) is one of the most well-known and popular fruit trees, widespread in many countries across Europe. It is particularly popular in Hungary, where a variety of plum cultivars can be found. One of the most well-known varieties is the Bluefree, which captivates the hearts of both fruit growers and consumers with its excellent taste and abundant yield.

### Variety Description

**1. Appearance and Characteristics:**
The Bluefree plum tree is medium-sized, reaching a height of 4-6 meters when fully grown. The crown of the tree is dense and rounded, providing an attractive appearance in the garden. The young branches are green and smooth, while the older branches develop a gray, cracked bark over time. In spring, the trees are covered with white or light pink flowers that appear before the leaves. Blooming usually begins in April, and the flowers are self-pollinating, so the presence of other varieties is not necessary for fruit development.

**2. Fruit:**
The fruits of the Bluefree plum are large, typically 5-7 cm long and oval-shaped. Their skin is thin, dark blue, and covered with a thin white waxy layer. The flesh is yellowish, juicy, and sweet, with a slightly tart flavor. The ripening period is from late July to early August, allowing the fruits to be enjoyed in the summer. The Bluefree plum is excellent for fresh consumption, but it is also popular for processing into jams, syrups, dried fruits, or baked goods.

**3. Cultivation and Care:**
The Bluefree plum tree thrives best in sunny locations, as sufficient temperature and light are fundamental for the ripening of the fruits. The soil should have good drainage and be rich in nutrients. After planting, it is important to regularly water the young trees, especially during the fruit ripening period. Pruning helps shape the crown of the tree and promotes airflow and light penetration. A spring pruning has positive effects on the quality and quantity of the fruits.

**4. Diseases and Pests:**
The Bluefree plum tree is resistant to most diseases; however, it is not immune to Monilia, leaf spot disease, and other fungal infections. Aphids and plum fruit flies can also damage the fruits. To maintain the health of the trees, regular inspections and the application of necessary plant protection products are important. Biological control methods, such as the use of neem oil, can help manage pests.

**5. Harvest:**
The fruits of the Bluefree plum typically ripen at the end of July and the beginning of August. The ripeness can be assessed by color and firmness. The fruits should be soft and colorful at the time of harvest. The harvest is typically done by hand, with care taken to ensure that the fruits are not damaged.
