Bonsai Tree Care for Beginners: A Practical Guide
Keeping a bonsai alive comes down to four steps, taken in order: identify your tree, put it in the right position, water it by the soil rather than the calendar, then settle into a simple routine. Get the first step right and the other three become much easier.
Bonsai is a way of growing and shaping a tree in a small pot, not a single type of plant, so care depends on the species you own. Each step below gives you the essentials and links to a detailed guide when you need more.
Your route through bonsai care:
- Identify your tree: indoor or outdoor species?
- Choose its position: enough light, away from vents
- Check watering: when the soil starts to dry
- Understand routine care: soil, feeding, pruning and repotting
Step 1: Identify Your Tree
Find out your tree’s botanical name before anything else. Check the label or ask the nursery. Every other care decision depends on whether it’s an indoor or an outdoor species.
| Type | Common species | Where it lives |
|---|---|---|
| Indoor (tropical and subtropical) | Ficus, dwarf jade, Fukien tea, Ming aralia, serissa | Inside, near a bright window |
| Outdoor (temperate) | Juniper, pine, Chinese elm, Japanese and trident maple | Outside, in sun, year-round |
If this is your first bonsai and you want it indoors, choose a ficus. It’s the most forgiving species for beginners.
Juniper is the most common beginner mistake. It’s widely sold as a desk bonsai, but it needs full outdoor sun and usually declines within a year inside.

Step 2: Choose Its Position
Lack of light is the most common reason bonsai struggle. Place your tree by what its species needs:
- Indoor species: within one metre of your brightest window. In Australia, north-facing is usually best, with east-facing a good second. If no window is bright enough, use a full-spectrum LED grow light 20–30 cm above the tree for 12–14 hours a day.
- Outdoor species: at least 4–6 hours of direct sun a day, and more for junipers and pines. Light afternoon shade helps during the hottest inland summers.
Wherever it sits, keep the tree at least a metre from heaters and air-conditioner vents, and keep leaves off hot or cold window glass. Once you’ve found a good spot, leave it there; frequent moves cause leaf drop.

Step 3: Check Watering
Check your tree every day, but water only when the soil tells you to. No fixed schedule works: the same tree may need water twice a day in summer and once a week in winter.
- Push a finger or wooden chopstick 1–2 cm into the soil.
- Still damp: leave it and check again tomorrow.
- Just dry: water gently over the whole surface until water runs from the drainage holes.
- Let it drain, and empty any saucer so the roots never sit in water.
Species matters here too. Ficus, Fukien tea and most outdoor trees like evenly moist soil. Dwarf jade is a succulent and prefers to dry out most of the way between waterings.
Small bonsai pots dry out fast, so a bonsai often needs water more often than a houseplant. Don’t let the soil dry out completely.

Step 4: Understand Routine Care
With species, position and watering right, the rest is a light routine.
| Task | How often | Essentials |
|---|---|---|
| Check soil moisture | Daily | Finger or chopstick, 1–2 cm down |
| Inspect for pests | Weekly | Look under leaves and along stems for scale, mealybug, spider mite and aphids |
| Feed | Every 2–3 weeks, about September to April | Balanced fertiliser at half strength, onto damp soil; reduce or stop in winter |
| Trim new growth | As shoots extend, spring to autumn | Sharp bonsai scissors; cut back to the shape you want |
| Repot | Every 2–3 years (young trees) to 3–5 years (older trees), in early spring | Fresh, gritty bonsai mix in a pot with drainage holes |
Soil and pot: Use a free-draining bonsai mix of pumice or scoria, akadama and fine pine bark, never ordinary potting mix. Every pot needs drainage holes covered with fine mesh. Don’t add a gravel layer at the bottom; it raises the wet zone into the roots.
Tools: You need only bonsai scissors, a watering can with a fine rose and a chopstick to start. Add wire, cutters and root tools as your skills grow.
When something looks wrong: Don’t reach for fertiliser, secateurs or a new pot. Check the four basics first: Is it the right species for where it lives? Is the light good enough? Is the soil too wet or too dry? Are there pests?

Common Beginner Mistakes
| Mistake | Do this instead |
|---|---|
| Keeping a juniper or other outdoor species indoors | Grow it outside in sun, year-round |
| Placing an indoor tree away from the window | Keep it within a metre of bright light |
| Watering on a fixed schedule | Check daily; water when the top 1–2 cm is just dry |
| Overfeeding, or feeding a struggling tree | Half-strength feed in the growing season, only for healthy trees |
| Repotting every year | Repot every 2–5 years, in early spring, when roots fill the pot |
