Juniperus tetragona

Propagation: The seed requires a period of cold stratification. The seed has a hard seedcoat and can be very slow to germinate, requiring a cold period followed by a warm period and then another cold spell, each of 2 - 3 months duration[1][2]. Soaking the seed for 3 - 6 seconds in boiling water may speed up the germination process[3]. The seed is best sown as soon as it is ripe in a cold frame. Some might germinate in the following spring, though most will take another year. Another possibility is to harvest the seed 'green' (when the embryo has fully formed but before the seedcoat has hardened). The seedlings can be potted up into individual pots when they are large enough to handle. Grow on in pots until large enough, then plant out in early summer. When stored dry, the seed can remain viable for several years[4].

Cuttings of mature wood, 5 - 10cm with a heel, September/October in a cold frame. Plant out in the following autumn[4][1].

Layering in September/October. Takes 12 months[1].

Cultivation: Succeeds in most soils if they are well drained, preferring a neutral or slightly alkaline soil[4] and succeeding on chalk[5]. A drought tolerant plant once established, succeeding in hot dry positions[5].

This species is not very hardy in Britain[4].

Dioecious. Male and female plants must be grown if seed is required.

Range: South-western N. America - Texas to Mexico.

Habitat: Pine-oak forests in mountains, to 4500 metres in Mexico[6].

Edibility: Fruit - raw or cooked[7]. A sweet resinous flesh[6]. The fruits are about 12mm in diameter[8].

Usage: Wood - brown, hard. Used for construction etc[9].

Pollinators: Wind

Soil: Can grow in light, medium, and heavy soils.

Drainage: Prefers well drained soil.

In Leaf: Evergreen

Seed Ripens: Mid Fall

Flower Type: Dioecious
