How to Grow a Bonsai Tree from Seed Step by Step

Loading ....

Bonsai is a miniature plant propagated in a container. It is just like any other plant but bonsai is somewhat different because it is maintained in its small size. A bonsai tree can be cultivated from a cutting or seed. Bonsai seeds do not actually exist.

Bonsai are just derived from a normal tree seed. The tree seed should be planted in a container, repotted according to the needs of a certain bonsai tree species, its branches and roots are pruned on a scheduled basis, and its trunk and crown are trimmed to be a bonsai. Cultivating a bonsai tree seed requires extra care, patience, and proper knowledge.

Bonsai tree seeds are available in all gardening stores and even online businesses. You can choose whatever species you like but make sure you know how to properly germinate and care for it. You have to ask or read instructions on how to germinate and care for the specific species you bought because each species has different specific requirements in order to grow and develop into a beautiful and healthy bonsai tree.

Germination

One very important factor in the success of bonsai tree seed germination is to maintain its freshness. If you are not ready to plant your bonsai tree seed, you place it in a plastic bag. Label it so that you won’t get confused about what species it belongs especially if you purchase a number of bonsai tree seeds.

You should refrigerate the bonsai tree seed at a temperature of 5-6°C. This will be a perfect temperature for them. If you are ready to plant it, there are two germination methods you can choose from namely, natural germination and forced germination.

Natural germination involves planting the bonsai tree seed in the required type of soil during autumn. Scarification and stratification, which are required processes for seeds to germinate, normally take place during the winter season. Then, the bonsai tree seed will sprout next spring.

Forced germination involves the artificial accomplishment of the germination process. It includes three steps: scarification, stratification, and sowing. Most of the species need the three steps, while some may need more or less than these three steps.

1. Scarification

The first step in forced germination is scarification, which is a process that softens the outer shell of the tree to allow the water to reach the inside portion of the seed. You need to put the seeds in a bowl with water for about 24 to 48 hours.

Scarification

The water that will be used primarily depends on the species of the bonsai tree seed; they may require boiling water, warm water, or water in a room temperature. After soaking, you will only use the seeds that go under the water because they can live. The floated seeds should be discarded because they are empty.

2. Stratification

The second step is stratification, a process wherein a seed undergoes pretreatment to activate natural winter conditions because this is required for the seed before germination. Cold stratification is used for species that require cold weather before they undergo germination in the summer.

Stratification

You just have to place the seed in a moist medium (paper towel, peat, or sand). Then, put it inside a ziplock container. It must be placed in the refrigerator and store for 90 to 120 days. The seeds undergo dormancy at this period before they can proceed to the germination process.

Some species may require heat stratification. It is preceded by cold stratification; it serves as an interruption to the cold stratification process. For a specific period of time, the bonsai tree seeds are placed in a bowl and exposed a room temperature.

Then, it is placed back in the refrigerator to continue the cold stratification process. It is very important to have adequate knowledge about the bonsai tree seed species you are about to buy to ensure proper processes and timing will be followed.

3. Sowing

The last step is sowing. The bonsai tree seed is planted in suitable soil for a specific species. You can plant it in a container or in the ground. You should plant the bonsai tree seed half-inch down in the soil. You should keep the soil moist to allow the seed to grow.

Basic Growth Requirements for Bonsai

After planting the seed, it is very essential to consider the amount of light and water it will receive. You should water it on a regular basis. You should check out the soil where your bonsai tree seed is planted. Prevent the soil from getting dry as this can cause dehydration and death to your growing seed.

Enough sunlight should be given to your planted bonsai tree seed. If it is planted outside, you should make sure that enough sunlight can reach it. If it is planted in a container and placed inside your home, you should place it near the window that sunlight can get through it.

Water and sunlight are basic requirements for the bonsai tree seed to grow. Thus, knowing your bonsai tree seed species about its growth requirements is necessary to support its proper growth and development.

Quick and Easy Techniques to Starting Bonsai from Seed

I am here to show you some quick and easy techniques about starting bonsai from seed. It is a really simple process for you to carry out.

What you need to prepare:

  • Dish with holes at the bottom
  • Screen
  • Bonsai seeds
  • Soil mix
  • Sand
  • Water

You can start out by preparing a  dish, and you put a screen in it. You have to have holes in the bottom of the dish so it allows the water to drain. Put a screen in it to prevent the soil from falling out.

When comes to choose the bonsai seeds, it is recommended for you to use the real bonsai soil mix. It’s better for starting out the seeds because it’s got a lot of aeration and has a lot of water retention. It’s very loose so the seedlings don’t struggle when they’re sprouting.

Then, you can get a whole bunch of seeds that you have been accumulating and you may just do things like a potpourri batch. Plant them all and see what happens.

What you need to do first is to cut the little section off the seeds or file a little section of the seeds where the seed was attached to the plant you can see it’s almost like a little dimple.

You may cut the larger seeds or trim them off. By doing so, it will help to break the shell of the seed so the seed can sprout and germinate out of this hard shell. Then put them all in warm water and soaked for 24 hours.

After 24 hours, any of the floating seeds should be taken out because they are unviable. But you need to pay attention to some light seeds and you shouldn’t take them away. They aren’t sinking because of their shape and not because they are unviable.

You can carefully water your bonsai soil mix and let the water absorbs. After the water has soaked right into the soil mix, you will get good watering on your soil mix.

Next, you can start to put those bonsai seeds just all over the place in random patterns. You can simply place them in the soil with almost no covering. With that, it makes the seeds to be very easy to sprout without much of a strain.

Then, cover them with a thin coating of sand to keep everything protected. The thin coating of sand will keep the seeds protected and also keep the moisture in the soil.

That’s almost it. From now on, you just need to water them on a regular basis to keep the soil reasonably moist.

After 1 or 2 weeks, some of the seeds will start to sprout. So you know planting bonsai from seeds is a numbers game. You got to do a lot of them to get viable seeds.

How long does it take to grow a bonsai tree from a seed?

Planting a bonsai tree from a seed is a slow and satisfying process. If you plant a tree, you must give it some time to root and strengthen it before you start pruning and trimming it.

Depending on the species you want to grow, it may take up to 5 years for a bonsai tree to grow into a decent height. Many people believe that such a long time and effort is worthwhile because seeds are very economical and people can control the tree at every stage of its growth.

Something to Pay Attention to When Growing Bonsai Tree from Seed

  • If you are growing Judas Tree and Japanese Maple Tree, it can be very helpful for you to use sandpaper on the seeds right before you put them in the water container for the required 24 or 48 hours. By doing so, it will help the plant to grow faster when you put it in the soil. What you need to pay attention to is not over or under-watering it.
  • When doing the wiring, you need to be careful by not doing it forcefully which can accidentally snap the branches. Therefore, you need to wire them gently and slowly.
  • If you are growing the pine bonsai, you can sow all the seeds at once into the dish. Then you can take them out to separate them into one tree per pot.
  • If you are growing Japanese Black Pine Tree Seeds, you will need to sow one seed per pot. Or else they won’t have enough space to grow.
