Ginkgo biloba 1-7

It needs a substrate that is always moist. Water it regularly while allowing the root ball to dry out slightly between waterings to avoid excess water. 

In spring/summer, watering will be done regularly, when it's hot, it's every day ! On the other hand, in winter, water according to the soil monitoring you do. Thanks to the rain and cold, you won't necessarily need to water regularly since the substrate will remain moist. 

Important : Don't hesitate to water the entire root ball up to the roots, the water will drain away through the holes under the pot or bathe the tree in water (drenching) for a few minutes, to be sure to water well up to the roots. We do not recommend putting a cup or container underneath your pot as the water will stagnate and can cause root rot. (Too much water = asphyxiation). 

In the nursery, we use agricultural soil composed of black peat, blond peat, eco-aged, topsoil, horse manure, pozzolana. During the next repotting, which is done about every 2/3 years at the beginning of spring, you can mix more draining substrate such as: akadama, pumice, kiryu... Just be careful not to disturb the root bread, don't destroy the whole root ball

Many bonsai react noticeably when repotted at the wrong time or too drastically. For this reason, you should cut as few roots as possible

Young trees have an "open " branch shape, but as they age, they develop dense columns. We advise you to structure your tree according to its natural shape because the Ginko Biloba has quite large leaves that are difficult to reduce. During the flowering period, prune the jets to 2 or 3 leaves, being careful to cut above one leaf facing outwards. Be careful, do not prune strong branches because ginko does not heal well.

In the nursery, we use NPK 12, 12, 17 blue tomato/flower fertilizer. Put a handful of them on the substrate (small or large depending on the size of the pot) from spring to autumn, every 2 months , alternating chemical/organic.
