Persikkapuu

Persikkapuu, Finnish for the peach tree, refers to Prunus persica, a deciduous fruit tree in the Rosaceae family. Native to Northwest China, it is now cultivated in temperate regions worldwide for its aromatic stone fruit. The tree is typically medium-sized, reaching 4–6 meters, with a broad, open canopy. Young shoots are slender and brown; leaves are oval, 3–8 cm long with fine serrations. In spring, the tree bears pink-to-white blossoms before leaf emergence. The fruit is a drupe with a fuzzy epidermis, varying in color from yellow to red depending on cultivar, and containing a hard stone.

Growth and cultivation: Peach trees require warm summers and a period of winter chill; they tolerate a range of soils but prefer well-drained, fertile sites and full sun. They are sensitive to late frost during bloom and may be managed with pruning and irrigation. In commercial orchards, propagation is by grafting or budding onto hardy Prunus rootstocks. Varieties are chosen for climate, disease resistance, and fruit quality; many are not fully self-pollinating and rely on bees for pollination, though some cultivars are self-fertile.

Uses and varieties: Peaches are consumed fresh or processed into jams, desserts, and canned products. Cultivars are categorized as freestone or clingstone and as melting or non-melting flesh, with a wide range of flavors and colors.

Pests and diseases: The crop faces issues such as peach leaf curl, brown rot, peach scab, and aphids; management combines cultural practices, monitoring, and fungicidal or insecticidal treatments as needed.
