A new care guide for 2020; this care sheet is intended for complete beginners to help them care for their Ficus retusa indoor bonsai tree and covers watering and feeding etc..
Watering your Ficus bonsai
This is very simple for the Ficus bonsai. Regular watering is not essential. The soil damp be maintained just damp.
Misting the leaves of your Ficus bonsai will increase humidity. If you use our bonsai mist, it will help to condition the leaves.
Feeding bonsai trees is good practice. The bonsai rely on us to provide the nutrients and trace elements they need. A well balanced bonsai feed, such as Bonsai Direct Fertiliser, will maintain healthy and beautiful trees and promote growth, fruiting and flowering.
To maintain the lovely highly defined foliage pads and pretty canopy it is important not to let the shoots grow too long and straggly. By keeping the shoots trimmed, you will be encouraging back budding and new leaves to grow. Most new growth will appear during spring or summer. Allow a shoot to grow approx. 4cm and then prune back to the first two new leaves. Use a sharp pair of bonsai pruning scissors to do this. Within 4-6 weeks you can usually see signs of new shoots emerging further back down the branches, it is very rewarding.
Re-potting your Ficus bonsai
If a bonsai becomes pot bound the roots cannot grow. Consequently, the tree cannot grow. The younger the tree the quicker it is growing and the more frequently it will require root pruning or re-potting. As a general rule you are looking at approximately every 2-3 years, and older specimens every 4-5 years. If the pot that your bonsai is in is aesthetically large enough, you may simply be able to root prune your bonsai and it may not require a larger pot at all. Re-potting is best done when the bonsai is actively growing during the warmer summer months.
If the bonsai requires a larger pot, simply lift the root ball out of the current pot, tease out approximately one quarter of the root ball with a chop stick to loosen the roots around the edge and position into its new, slightly larger, pot. Use good quality, free draining soil, such as Akadama, and work around the edge of the pot. Stand your re-potted bonsai in water, so that the water covers the whole pot, for approximately 5 mins and then allow to drain.
Akadama is a high quality Japanese bonsai soil made from dried loam. It is granular, so is free flowing and easy and clean to work with. The small balls also encourage the growth of lovely fibrous feeder roots, which is what we want when growing bonsai trees.
Please avoid using air freshener near your bonsai, they are not overly keen!
Ficus bonsai trees respond well to the use of a Plant Invigorator to help keep the free from pests and help promote new growth. We use this weekly as a preventive measure.
