Black Pine seeds, Ref. 5700

Seeds (5 pieces per pack).

Japanese Black Pine (Pinus thunbergii) is an evergreen conifer that reaches a height of 30 meters. It is one of the symbols of the art of bonsai because it conveys the beauty of the tree.
Its blackish-grayish bark, which becomes coarser with age, is especially expressive. The crown is conical in shape with horizontally growing branches and bright green lush needles.

Pine seeds require stratification at +1-5ºC for a month.
Pre-soak them for a day in warm water, and then plant to a depth of about 7 mm in a mixture of high peat and humus (2:1), and put on the bottom shelf in the refrigerator for 1 month, covered with plastic wrap dishes with seeds. After a month move to a bright place, as the seeds are photosensitive and germinate in the light for 5 to 8 weeks. Sprouts need to be aired. Overwatering and drying out of the seeds should be avoided.
To germinate seeds in a container, a container should be chosen of medium size, at least 15 cm deep, and each seed should be planted in its own pot, so as not to traumatize the delicate roots during picking.
Before sowing, containers are necessarily disinfected, using a solution of potassium permanganate. Sand with claydite is calcined in an oven at 220 ºC for 20 minutes, and fertile soil is poured steep boiling water or a weak solution of manganese.
The soil should be slightly moist. Plants tolerate drought much better than too wet soil. You can do without spraying water with a sprayer even in the summer, since pine trees tolerate hot and dry environments well.
