Zelkova care tips

Light requirements for Zelkova

Zelkova parvifolia thrives in bright light. Place your bonsai near a window where it receives plenty of natural light throughout the day.

Direct sunlight for a few hours is usually fine, but very strong afternoon sun can sometimes dry the soil quickly.

Expert tip! If your bonsai starts losing leaves or growing very long shoots, it may need more light.

Watering

Bonsai trees require consistent watering because they grow in relatively small pots. Water your Zelkova when the top layer of soil feels slightly dry.

Make sure to water thoroughly so the entire root ball becomes moist.

Expert tip! It’s better to water deeply than to give small amounts frequently. This helps the roots stay healthy.

Never allow the soil to dry out completely.

Nutrition

During the growing season in spring and summer, your Zelkova will benefit from monthly feeding with a bonsai fertiliser or balanced houseplant fertiliser.

This supports healthy leaf growth and helps the plant stay strong.

In autumn and winter, fertilising can usually be reduced or stopped.

Temperature & humidity

Zelkova bonsai trees grow best in temperatures between 15–25°C. They adapt well to normal indoor humidity levels.

Avoid placing the bonsai near heaters, air conditioning units or cold drafts, as sudden temperature changes can stress the plant.

Soil & repotting

Bonsai trees require well-draining soil that allows air to reach the roots. Special bonsai soil or a well-draining mixture works best.

Repot your Zelkova every 2–3 years in early spring. This refreshes the soil and prevents the roots from becoming too crowded.

When repotting, gently trim some of the roots and place the plant in fresh soil.

Propagating Zelkova

Zelkova parvifolia can be propagated through stem cuttings.

Here’s how to do it:

1. Cut a healthy young shoot from the plant.
2. Remove the lower leaves from the cutting.
3. Place the cutting in moist potting soil.
4. Keep the soil slightly moist while roots develop.
5. Place the cutting in a warm spot with bright, indirect light.

Over time, the cutting can develop into a new bonsai plant.

Most common pests on Zelkova

Zelkova bonsai trees can sometimes attract pests such as aphids, spider mites or scale insects.

Regularly checking the leaves and stems helps catch problems early. If pests appear, gently wipe the leaves or treat the plant with a suitable plant care product.

Is Zelkova poisonous for your pets or children?

Zelkova parvifolia is generally considered non-toxic to pets and humans. However, it’s always best to discourage pets or children from chewing on houseplants.
