Fill a shallow tray with a layer of gravel.
Add a small amount of water.
Pop your bonsai into the tray.
This will give it some additional moisture to counteract the heating systems indoors.
How often do you have to water a bonsai tree? Your bonsai is one plant which you must never neglect to water!
As soon as the soil begins to look dry, top up the water.
You should never allow the soil to dry out completely.
If you have it positioned in a spot that gets plenty of sun, we recommend you water at least once every 1-2 days.
Do I need to fertilize my bonsai tree? It is definitely necessary to fertilize your bonsai to ensure it remains healthy! They usually grow in a small amount of soil, so fertilizing will ensure that your bonsai will get the nutrients it needs. Apply your fertilizer once a month throughout spring, summer and autumn.
How do I keep my bonsai mini? Trimming and pinching is the best way to ensure you bonsai stays miniature.
Pinch and trim back any new growth to a safe point – never removing all of the new growth.
Always leave a little to ensure the tree stays healthy.
Monitor the growth rate and adjust the timings of your pinch and trim to suit, as each bonsai will grow at a different rate.
Do I need to repot my bonsai? As your bonsai tree grows, its root system will fill the pot and therefore it may need repotting to allow it to grow, or to compact its roots. This will also give you a chance to freshen up the soil. Have a look at this toolkit of tips:
Deciduous trees require repotting every 2-3 years.
Evergreen trees require repotting every 4-5 years.
To be sure it needs repotting, check the root systems once a year.
Remove the tree, and all of the soil, from the pot.
Remove the outer and bottom ¼ of your bonsai’s root mass by raking away the soil and pruning the roots.
Simply pop your bonsai back into its original pot to compact the roots or repot into a new pot to allow it to grow.
If you’re repotting in a new pot don’t forget it will need drainage holes, a layer of gravel beneath the soil and fresh soil to elevate the height of your bonsai.
