How to choose a pomegranate bonsai

If you can visit a store to choose your bonsai, there are some characteristics of the pomegranate that can help you select a more beautiful and healthy plant.

Trunk: It takes several years for the pomegranate to develop a thick trunk, and the trunk of a pomegranate is unlikely to thicken when grown as a bonsai. Therefore, look for a tree with a thick trunk.
Bark: As mentioned at the beginning of this text, a wrinkled and scaly bark adds a unique beauty to this bonsai.
Leaves and flowers: Look for healthy and vibrant leaves. If you visit the store during the flowering season of this plant, be cautious of faded, discolored, or spotted flowers.
Seller: Make sure that the place where you’re buying this plant is reliable and has bonsai experts. This way, you avoid the risk of buying a plant that may have pests or diseases.

After choosing your pomegranate bonsai, it’s time to learn the main care you should provide for it.

Placement

Thanks to the climate of its natural habitat, the pomegranate loves sunlight and can be grown outdoors.

The ideal condition for this bonsai is to provide at least 6 hours of direct sunlight daily. Therefore, a balcony or a well-lit window is a great option.

On very hot days, protect your pomegranate bonsai from direct sunlight during the hottest parts of the day.

Similarly, be cautious of frost.

During winter, to ensure proper dormancy, aim to provide a temperature between 2°C and 8°C (36°F and 46°F) for your pomegranate bonsai. Because it loses its leaves, light is less important during dormancy, but avoid keeping it too warm, or it will produce weak shoots.

Watering

Throughout the year, the watering needs of this bonsai change significantly.

Therefore, pay attention to the tips below to avoid mistakes in watering, which are among the most common bonsai problems.

The first and most important tip is:

Water when the soil dries.

This will happen more often in summer when the pomegranate’s flowers appear. During this period, you might need to water twice a day.

In this case, water in the early morning and late afternoon. In the hottest hours, the water evaporates quickly and the pot heats up, so the roots benefit less.

During winter, the frequency of watering will decrease significantly. Water only when the soil starts to dry, which may take a week or more.

During this period, be very cautious not to water when the temperature is too low, as this can freeze the soil and kill your plant.

Ideally, water your plant in the early morning.

Now, in spring and autumn, watering is usually done once a day. Try to water during the morning hours and avoid watering your plant during very hot or cold moments.

Checking if the soil is moist

With the tips above, you’ll likely get the watering frequency of your pomegranate bonsai right.

However, there are several factors that can make your plant need more or less water. The main ones are:

Temperature: The higher it is, the more you’ll need to water
Humidity: The higher it is, the less you’ll need to water
Pot size: The larger it is, the less you’ll need to water (this can vary)

Therefore, below you’ll learn how to check if the soil of your bonsai is moist. Remember that the ideal watering for the pomegranate is just after the soil dries.

Follow the 2 steps below:

Insert your finger into the soil up to 2.5 cm (1 inch)
Feel if the soil is moist. If it feels dry, water; if it’s still moist, wait.

During watering, be careful not to oversaturate your bonsai’s soil, as this can lead to root rot and other diseases. Learn more in the article on pests and diseases in bonsai.

Temperature and lighting

Lighting is likely the simplest factor in growing this bonsai.

Being a very resilient tree that thrives on sunlight, the pomegranate bonsai should be placed outside your house or in a window with plenty of sun.

To provide adequate lighting for your pomegranate bonsai, follow the tips below:

Direct sunlight in fall, winter, and spring, but make sure the soil stays slightly moist.
During summer, provide protection during the hottest hours (between 10:00 AM and 4:00 PM); typically, placing your bonsai on a balcony or under trees can be a good option.

Regarding temperature, the ideal range for this bonsai is 10°C to 25°C (50°F to 77°F), while in winter, temperatures of 2°C to 8°C (36°F to 46°F) support its dormancy.

Fertilization

Fertilization is extremely important for the development of your bonsai.

With it, you’ll be able to provide the nutrients your plant needs to grow, be healthy, and produce flowers and fruits.

For the pomegranate, there are two types of fertilization:

Organic: Using natural fertilizers
Inorganic: Using synthetic fertilizers

Normally, organic fertilization is recommended for growers who are still starting their journey.

This type of fertilization is milder, but it also poses lower risks to your bonsai.

To organically fertilize your pomegranate bonsai, follow the steps below:

Use organic bonsai fertilizer pellets and bone meal
Fertilize with just one of these every 2 months (e.g., month 1: organic pellets – month 3: bone meal – month 5: organic pellets, and so on)

Inorganic fertilizers require a bit more caution.

They are more efficient and faster, but you must be very careful not to over-fertilize your bonsai.

To avoid this mistake, we recommend using only half of the recommended dosage on the packaging.

For example, if the packaging recommends 20 ml per 1 liter, use 10 ml per 1 liter.

As for fertilization, follow these tips:

Fertilize every 20 days
Do not fertilize during winter or intense flowering periods
To promote more flowers and fruits, use a fertilizer with higher phosphorus and potassium content from spring to summer (e.g., a 4-14-8 NPK formula)
After repotting your bonsai, wait at least 3 months before the first fertilization

Choose the best fertilization method for you and fertilize your bonsai.

Pruning

Structural pruning is done in late winter or early spring, before new growth starts.

During the growing season, maintenance pruning prevents your tree from growing excessively: trim new shoots back to one or two pairs of leaves.

To get flowers, let the shoots grow from midsummer until flowering ends, and only then trim them.

To perform it, you should have sharp bonsai shears to avoid crushing the branches of your pomegranate and causing damage.

Cut the branches that emerge from undesired areas of your bonsai.

NOTE: Pruning to a triangular silhouette is typically the best approach for the pomegranate bonsai.

Repotting

Repotting involves changing your bonsai’s pot.

This typically happens every 2 to 3 years, with younger plants requiring more frequent repotting.

During repotting, follow these tips:

Gently remove the old soil from the roots
Remove dead or rotten roots
Avoid cutting thicker roots, as this can dry out some branches of your bonsai
Repot in spring
After repotting, place your bonsai in a location protected from the strongest sunlight

Propagation

Propagation is a slightly more advanced topic.

So, if you don’t want to propagate your bonsai, it won’t hinder your cultivation in any way.

Essentially, you can propagate your pomegranate bonsai through seeds or cuttings.

If you want to learn how to take cuttings, watch the video below.

Growing from seed

Fortunately, pomegranate seeds sprout easily without much assistance.

Below are some tips that can increase your success rate in planting pomegranates.

Plant during warmer months
Clean and dry the seeds before planting
Plant them in quality soil at a depth of about 1 to 1.5 cm (around 1/2 inch)
Keep the soil moist and expose the pot to sunlight every day
Wait for germination to occur; this can take up to 6 weeks

Once the seedlings have a few pairs of true leaves, you can move them into individual pots.

Now, just keep caring for the plant and follow the steps in the video below to gradually transform your pomegranate tree into a pomegranate bonsai.

Remember that this is a lengthy process: seedlings take a few years to flower, and it can take years to achieve the ideal result of a beautiful bonsai.

So, be patient.
