Pinus thunbergii fresh seeds, Black pine, Japanese black pine, Japanese pine, Coniferous tree seeds, Organic seeds (lat. Pinus thunbergii).

Plant, a widespread species of the genus Pine of the Pine family (Pinaceae). It grows naturally in Japan and South Korea.

Tree up to 30 m high with a wide crown and trunk diameter up to 2 m. The bark is scaly, gray-black. The shoots are orange-yellow. The buds are elongated, 1.2-1.8 mm long, whitish. The needles are arranged two in a bunch, 6-11 cm long and 1.5-2 mm thick. They live on trees for up to 3 years.

The cones are ovoid, 4-6 cm long and 3-4 cm thick, brown in color. Seeds 5 mm long, with wing. Pollination occurs from April to May, the seeds ripen two years later in October.

Loves sunny places, but also tolerates light shade. It is recommended to place it on a hill so that the lower branches receive enough light. You should always choose a well-warmed place for better tree growth. The only exception is excessively wet and closed areas with poor air ventilation, especially during the rainy and frosty seasons, since such conditions are difficult for the roots. It can winter outside, but the plant must be protected from excess moisture.

Can occur in a variety of soil types, including bare mineral soil, sandy soil, volcanic ash, limestone soil, limestone soil and everything from dusty soil to red soil. Because it is drought tolerant, it will grow even in barren landscapes.

USDA Hardiness Zone: 6 (-23°C to -18°C).

Instructions

Growing Japanese Black Pine Tree (Pinus Thunbergii) from seed is a rewarding process. Follow these guidelines for best results.
Seed Preparation: Cold stratification is required. Place seeds in moist sand or vermiculite in a sealed bag and refrigerate at 1–5°C for 4–8 weeks before sowing. Some species may require 60–90 days of cold stratification for optimal germination.
Sowing: Sow seeds 0.5–1 cm deep in well-draining seed compost mixed with sharp sand or perlite. Water gently and keep in a cold frame or unheated greenhouse at 18–22°C.
Germination: Seeds may germinate over 2–8 weeks depending on species. Some conifers require a warm period (20°C for 4 weeks) followed by cold stratification before germination will occur.
Transplanting: Transplant seedlings into individual pots once they have 2–3 pairs of true leaves. Harden off gradually over 7–10 days before planting in final position. Space according to the mature size of the species.
Aftercare: Keep soil evenly moist, especially during the first growing season. Apply a layer of mulch around the base to retain moisture and suppress weeds. Protect from strong winds until established.
Hardiness: Hardy in most temperate climates. Suitable for USDA zones 4–8 depending on species. Established plants can tolerate winter temperatures well below freezing.
