As winter settles quietly around us, our bonsai rest in their deep, unhurried sleep. In this stillness, we’re reminded of a simple Zen truth: nothing in nature rushes, yet everything unfolds in its own time.
May this new year invite us to slow down, breathe deeply, and appreciate the quiet beauty of our trees – their bare silhouettes, their patient strength, their trust in the seasons.
Just as our bonsai gather energy beneath the surface, may we also find renewal in these calm winter days. When spring returns, we’ll meet again with fresh hands, open hearts, and new growth waiting to be shaped.
Until then, may peace, clarity, and gentle purpose accompany you into the year ahead.
❄️ Winter Care Reminders for Zones 7a & 7b
- How to protect roots during freeze–thaw cycles
- In our region, the biggest winter danger isn’t steady cold — it’s the yo‑yo of warm days and sudden hard freezes.
- Keep pots out of direct sun to slow rapid thawing. North‑facing walls, shaded patios, or under benches work well.
- Mulch around pots with pine needles, leaves, or bark to insulate root zones.
- If trees are in a cold frame or shed, keep temperatures stable — not warm, just consistent.
- Avoid placing pots directly on concrete; elevate them slightly or place them on wood to reduce conductive freezing.
- When to water (and when not to) in cold, dry air
- Even dormant trees need moisture, but far less than in spring or summer.
- Water only when the soil surface is dry and the pot feels noticeably lighter.
- Choose midday on above‑freezing days so water can soak in before nighttime lows.
- Avoid watering frozen soil — the water won’t penetrate and can damage roots. 🪷Ken’s latest advice.
- Tips for monitoring trees in garages, sheds, or cold frames
- Trees stored in garages or sheds dry out more slowly, so check them weekly rather than on a schedule.
- Aim for temperatures between roughly 28–40°F — cold enough for dormancy, not so cold that roots freeze solid.
- Provide some airflow. Stagnant air encourages mold, but strong drafts can dry trees out.
- Check for rodents if trees are stored in outbuildings; they love chewing bark in winter.
- Keep light low as dormancy doesn’t require bright light, and too much warmth + light can trigger early budding.
- What “healthy dormancy” looks like
- Buds are tight, firm, and not swelling prematurely.
- Branches remain flexible, not brittle.
🌲 Winter Spotlight: Japanese Black Pine (Pinus thunbergii)
The Japanese black pine brings strength and presence to the winter bench. While deciduous trees rest bare, this evergreen stands steady, offering color, texture, and a reminder that not all growth sleeps at once. In our Reno and Carson City climate with bright sun, dry air, and freeze–thaw swings this species remains one of the most reliable winter performers.
- Needles stay vibrant and full, adding life to the winter landscape
- Strong bark and bold structure become more visible in low winter light
- Naturally tolerant of cold when roots are protected from rapid temperature changes
Winter Care Notes for Zones 7a/7b
Japanese black pines appreciate the cold, but they still benefit from thoughtful winter care in our high‑desert region.
- Cold Tolerance: Protect roots from freeze–thaw cycles with mulch, pot‑in‑pot setups, or cold frames
- Sunlight: Enjoys winter sun, but avoid warm afternoon thawing
- Watering: Water only on above‑freezing days when the top layer feels dry
- Wind: Provide a windbreak to prevent needle desiccation
⭕A winter meditation
The Japanese black pine teaches a quiet lesson this time of year: strength doesn’t always look loud. Sometimes it’s simply the steady presence of green in a sleeping garden, the patience of buds waiting for warmth, or the calm endurance of a tree that trusts the seasons.
📚 Winter Learning Corner
- Recommended books
- I’ve been looking at my personal book library. I have books about bonsai, bamboo, moss and Japanese gardens. Winter is a great time to review techniques, strategies, rules and all things gardening. I recently moved and the contractors just finished putting in a modern Japanese garden. I reviewed these books to find ideas and inspirations.
- Here is a book I constantly return to.

A Christmas gift from my family this year is The Japanese Garden by Sophie Walker
An in-depth exploration spanning 800 years of the art, essence, and enduring impact of the Japanese garden. The most comprehensive exploration of the art of the Japanese garden published to date, this book covers more than eight centuries of the history of this important genre.

(315) Japanese Black Pine Seedlings to Beautiful Bonsai – YouTube - Did you know?
- 🌿Bonsai began over a thousand years ago in China as penjing, the art of creating miniature landscapes. When the practice reached Japan, it evolved into the more refined, tree‑focused form we now call bonsai. Today, it’s a global art that celebrates shaping living trees to reflect age, balance, and the spirit of nature.
🌬️ Local Climate Notes for Reno & Carson City
Why this matters for bonsai
These temperatures are cold enough for healthy dormancy, but the freeze–thaw swings in our high‑desert climate can stress roots – especially in shallow pots. That’s why mulching, grouping trees, and keeping pots shaded from afternoon sun is so important in winter
- Carson City (Zone 7a/7b)
Historical data shows that January lows typically fall between 22°F and 25°F, with colder nights occasionally dipping to around 11°F. - Reno (Zone 7a)
Reno’s January lows commonly range from the upper teens to mid‑20s, with many nights landing around 20–27°F based on historical monthly patterns.
🪷 Until the Light Returns
Until next month, may your days be calm, your trees protected, and your spirit steady as the season unfolds. We’ll meet again as the light slowly returns, carrying the promise of new buds and new beginnings.
