Growing Bonsai from seed

The Japanese term, “Misho,” refers to the practice of growing Bonsai from tree seeds. It can be a very rewarding process that allows you to grow a plant as a Bonsai tree from the very beginning, although it does demand a great amount of patience. It takes a minimum of three years before seedlings mature enough to start shaping, but it’s advantageous, as you have full control over your Bonsai tree from the beginning. Misho is the only real way to grow a Bonsai right from the start!

To get started, you need to get your hands on some tree seeds. You can collect seeds from trees in your surroundings or you can choose to buy them at an online shop. Keep in mind that Bonsai are created from normal trees, so there is no such thing as special “Bonsai tree seeds”.

Creating your Bonsai from seeds collected in your local area ensures that they will be in their ideal climate and are more likely to thrive. Locally sourced seeds should be planted during Autumn for the best results. However, if you want to plant local seeds out of season, purchase seeds online, or plant foreign seeds that come from a different climate, it may be necessary to use stratification techniques.


Stratification is the process of treating seeds to simulate the natural growing conditions that they need to germinate. Seeds of many tree-species are genetically programmed to survive through winter and germinate in early spring. This helps them maximize the duration of their first growing season. Most of these seeds can grow only after a cold period.

So, when you’re planting seeds for Bonsai that are from different climates, or you’re planting out of season, it may be necessary to simulate a cold season to increase the germination rate. Most tree-species will require you to soak their seeds in water before storing them in your refrigerator for one or two months. The exact amount of time and optimal temperature depends on the tree-species. A quick online search will provide you with an exact answer.

For beginners, this process may be too advanced, so we advise you to collect seeds from tree species in your area, keep the seeds outside and plant them in early spring, just like Mother Nature does!

Where do I find seeds?

As previously mentioned, you can collect seeds during autumn from local trees growing in your area. Chestnuts and acorns are easy seeds to find in the forest. Conifers seeds are found inside pine-cones. When you’ve collected the pine-cones, store them somewhere warm so they release their seeds from in between their scales. Seeds of various tree species are also easily available for purchase in online Bonsai shops.

When should I sow my seeds?

The best time to sow your seeds is in the autumn to align with nature’s schedule. This gives young seedling the full summer to grow after germinating in spring, and it means you don’t have to worry about stratification.

Before we start propagating seed, it’s important to know the seedlings stages of development first. Growing Bonsai from seeds will be a test of your patience, but it’s a great way to style Bonsai trees without the need to prune thick branches, as you would when styling Yamadori or nursery stock. Read the “Bonsai styling” section for more detailed information on wiring and pruning techniques.

Pros and Cons of Growing Bonsai from Seed


Growing bonsai from seed allows you to be involved in every aspect of your tree’s development, so you have the satisfaction of knowing that the work of art is completely your creation.

You can begin shaping and pruning much earlier in the tree’s life. This way, you can train your plant as it grows, rather than having to re-train what is already established. Seeds are less expensive than seedlings or mature plants.


Growing bonsai from seed requires a lot of patience, and extra care must be taken as new sprouts and seedlings are very delicate.

It will be at least three years before you will be able to start shaping or styling your tree. With an established plant, you can begin designing or creating immediately. Some seeds may need to be “stratified” or prepared for planting, which can be a complicated process, especially for beginners.

While growing bonsai from seed can be rewarding, it requires a lot of time and patience. If you are just beginning your journey into the world of bonsai, why not plant a few seeds and purchase an established tree.

Choosing and Preparing Seeds

Although there are no specific “bonsai” seeds, those prepared by companies specializing in bonsai supplies have had proven success and may be easier for beginners. If you choose to purchase your seeds, make sure to use a reputable supplier so that you won’t be disappointed with the results.

Of course, the least expensive way to obtain bonsai seeds is to collect them yourself from plants growing in your area or from mature bonsai trees already in your collection. It is best to gather your seeds when they are ripe, typically in late Summer or early Autumn.

Unless you are an experienced bonsai grower, it is recommended that you choose a species that is indigenous to your climate. This will ensure that your seeds will have the right conditions in which to germinate and grow.

If the seeds are fresh and have ripened within the current growing season, they can be planted right away. Otherwise, a process known as cold stratification is sometimes necessary.

Cold Stratification will be used if.

  • you want to plant your seeds out of season
  • the seeds have been stored inside and out of the soil over the winter
  • you are using seeds that will not germinate in your local climate

In nature, a seed will fall to the ground and remain nestled in the cold soil throughout the winter. When Spring arrives, the warming ground becomes very moist, bringing the seed out of dormancy and softening the shell so growth can begin.

If you are using packaged seeds or ones that have been stored indoors for a period of time, stratification is a way of artificially breaking dormancy and preparing the seeds for planting. Basically, by using moisture and temperature, you can re-create the conditions that occur in nature to encourage germination.

Steps for Cold Stratification

  • Soak the seeds in a container of water for 24 hours.
  • Seeds that sink to the bottom are the ripest, whereas floating seeds are usually empty shells that will not germinate.
  • Remove these seeds.
  • Place the good seeds on a damp paper towel.
  • Seal the paper towel and seeds into a clear plastic bag.
  • Place the bag in the refrigerator for 7 days to cold stratify.
  • Remove the seeds from the fridge and plant.

When to Plant Bonsai Seeds

For most species, the best time to plant is in the Autumn. Since seeds typically remain dormant during the Winter and germinate in early Spring, by planting in the Autumn you will be following nature’s timetable.

If you are using fresh, ripe seeds, sowing in the the Fall will also mean that you don’t have to worry about Stratification. And, young seedling will have the entire Summer season to grow and develop in preparation for the cold Winter.

How to Plant Bonsai Seeds

1. Choose a planting container. Some people prefer a pot, while others like to use a seed or starter tray. Keep in mind, however, that if you use a tray, you seedlings will have to be moved to a pot or deeper container once they sprout. Make sure that your container is not too small or you may find that you have to re-pot several times once your seedlings begin growing vigorously. It is also important that the pot have sufficient drainage holes to prevent the roots from rotting.

2. Cover the bottom of your container with fine gravel or sand to allow for good drainage.

3. Fill the starter tray or container with a suitable potting compost or bonsai soil to about 3/4”- 1” below the rim. Be sure to choose a nutrient rich soil, as your seedlings will need plenty of nutrition once they sprout. Pat the soil down lightly to ensure that it is settled, but not compact.

4. Use a chopstick or your finger to make shallow holes in which to place the seeds. Be sure not to sown the seeds too closely together or they will become overcrowded once they germinate.

5. Place a thin layer of bonsai soil over the seeds. This layer should be no more 1/2”-1” thick, depending on the size of the seeds you are planting. Sowing seeds too deeply may prevent them from germinating.

6. Water carefully, making sure that you do not disturb the seeds. Some people prefer to use a spray bottle, rather than pouring water directly onto the soil.

7. Put the container outside so the seeds can germinate naturally, or place it in a well ventilated location with minimal direct sunlight.

8. Keep the soil damp, but not wet. Do not let the soil dry out.

9. If your pot is outside, you can expect the seeds to germinate and sprout in early Spring. However, if you have used cold stratification or are growing your seeds indoors, you will likely begin to see sprouts about 4 weeks after planting.

10. Begin fertilizing about 5-6 weeks after the appearance of sprouts,but use a diluted solution as young root systems will burn easily.

11. After the first year, the seedlings can be separated and moved to their own pots.

While it will be about three years before your little trees are ready for training, growing bonsai from seed can be a rewarding experience. If you have the time and patience, beginning with a seed allows you to be in control throughout the entire artistic process.
