Growing bonsai from seed is a comparatively easy procedure in nurturing the seeds into youthful trees. Seed germination varies depending on the seed species. Seeds should be maintained fresh to facilitate their proper germination. Collected or purchased seeds should be stored in a moist-free container. Smaller seeds can be sown directly in spring and autumn. Larger seeds should be soaked for a minimum of 24 hours in lukewarm water. It is also necessary to make an incision if the seed’s protective layer is thick or hard. If the seed is protected by an external shell, it should be opened carefully with pliers. Seeds can also undergo stratification, wherein alternate layers of moist sand and seeds are formed to soften the seed.
It is ideal to sow bonsai seedlings in peat with sand or pure peat. The potting compost should be kept moist to facilitate the development of young roots. It should be cleared of pebbles or any bigger impurities. It is also necessary to disinfect the soil with steam or formalin to prevent diseases.
The seedling should be transferred to a pot once the first pair of leaves has sprouted. Great care is needed so that the roots or the seedling don’t get damaged. The seedling should be sowed in a temporary container to be transferred to a permanent container where the bonsai will be planted. It is important to cover the base with fine sand or gravel to ensure good drainage. The container should have a drainage hole to drain away excess water.
