Intro

The Juniper 'Nana' is a beloved outdoor bonsai, famed for its lush, trailing foliage and rugged aesthetic. Native to Japan, this slow-growing evergreen forms natural-looking mats that evoke ancient landscapes. It’s a resilient species that rewards patience and a light touch.

Care Instructions

Light

• Needs full sun—at least 4 to 6 hours daily.
• Do not keep indoors; it weakens without natural outdoor conditions.

Watering

• Water thoroughly when the topsoil is dry to the touch.
• Allow slight drying between watering, but never let the root ball go bone-dry.
• Avoid misting—Junipers dislike moisture sitting on their foliage.

Temperature & Climate

• Hardy to USDA Zone 4–9.
• Thrives in cool to temperate climates.
• Protect the pot in deep winter to avoid root freeze (e.g., mulch or overwinter in a cold frame).

Pruning

• Best time: Spring and early summer.
• Use sharp bonsai shears or pinch by hand.
• Do not cut back into old wood—junipers do not bud back easily.

Repotting

• Every 2–3 years, in early spring.
• Use a well-draining mix: akadama, pumice, lava rock.
• Remove no more than one-third of the roots during repotting.

Seasonal Tips

• Spring: Best time for repotting and pruning. Fertilize lightly as new growth appears.
• Summer: Monitor for pests and dry soil—Junipers can dry out quickly in heat.
• Autumn: Begin to reduce feeding; prep for winter protection.
• Winter: Keep outside in a sheltered spot. Protect roots if the pot may freeze.

Companion Moss & Plants

• Pairs beautifully with Kyoto moss or cushion moss.
• Add texture with small stonecrop succulents or dwarf ferns nearby.
• Avoid moisture-loving plants—Junipers need airflow and dryness around the roots.

Display Suggestions

• Ideal in rock-style containers or on slab displays.
• Use white gravel or crushed granite to simulate a mountainous terrain.
• Looks great as part of a mini zen garden, or atop driftwood for drama.
• Consider a windswept or cascade style to highlight its natural growth habit.
