The mulberry bonsai should be grown outdoors, preferably all year round.

This plant is highly resistant to both high and low temperatures, so it’s usually not necessary to bring it indoors or into greenhouses during winter.

The only exception is during extreme weather conditions:

  • Frost
  • Heavy rain

The chosen spot for your mulberry bonsai should receive a good amount of sunlight, especially during the early morning and late afternoon hours.

Sun exposure is crucial for this plant, especially when grown as a bonsai, as lack of light leads to larger leaves, which affects the bonsai’s appearance.

Once you’ve decided on a location for your mulberry bonsai, avoid changing its position frequently.

Lighting Care

As mentioned before, this plant should be exposed to sunlight throughout the year, receiving sunlight in the early morning and late afternoon.

Avoiding the hottest hours is important.f your Morus nigra bonsai is getting inadequate sunlight, you’ll notice:

  • Larger leaves
  • Abundant shoots

If you’re cultivating it indoors, artificial lighting might be necessary.

Ideal Temperature

The mulberry is highly resilient to temperature variations.

According to “revista jardins” (in Portuguese), the ideal temperature range for its cultivation is between 20°C and 30°C, with a minimum of 3°C and a maximum between 35°C and 40°C.

Very low temperatures, like 0°C, can halt the plant’s development, and -11°C can kill it.

Therefore, keep in mind that this is an extremely hardy bonsai, but it should be protected during extreme conditions.

The mulberry bonsai requires regular watering and proper humidity.

Because its leaves can easily dehydrate, during temperatures above 20°C, daily watering is necessary.

The ideal practice is to water your plant as soon as the soil dries out.

When watering your mulberry, make sure the soil is moist but not waterlogged. On very humid days, avoid wetting the leaves to prevent fungal growth.

Watering frequency will be reduced during flowering and winter.


Care must be taken when fertilizing this bonsai to avoid excessive leaf growth.

Fertilization is done during the plant’s growth period (spring and summer) and also during the autumn.

ertilization should be avoided in winter and during extremely hot periods.

There are two excellent options for fertilizers that you can use:

  • Organic fertilizers
  • Chemical fertilizers

If you opt for chemical fertilizers, choose one that is rich in Phosphorus (P) and Potassium (K), but low in nitrogen (N).

This way, you won’t stimulate excessive leaf growth and you’ll aid in the fruiting of your mulberry bonsai.

Transplanting should be done in early spring, just before the budding season. Do it approximately every 1 to 2 years, depending on your plant’s growth rate.

New plants usually grow faster.

During this process, you should remove rotten roots, unwanted branches, and some leaves.

If you heavily prune the roots, consider doing the same with the leaves and branches. Ideally, avoid drastic root pruning.

Using root stimulants with fungicides can increase your success rate during transplanting.

After transplanting, wait for your mulberry bonsai to start budding before applying new fertilization.

This way, you allow your plant to adapt to the new pot before receiving new nutrients.


Pruning is an essential aspect of bonsai care.

When done correctly, it helps maintain the size and shape you desire for your tree.

The mulberry bonsai requires frequent pruning due to its leaves. However, remember to allow some leaves to grow, as this promotes fruit formation on your mulberry.

The best time to prune your mulberry is after flowering, when you should cut between 1/3 and 2/3 of the branch length.
